    1979-01-01

    A thermal energy storage (TES) system developed for use with the Stirling engine as an automotive power system has gravimetric and volumetric storage densities which are competitive with electric battery storage systems, meets all operational requirements for a practical vehicle, and can be packaged in compact sized automobiles with minimum impact on passenger and freight volume. The TES/Stirling system is the only storage approach for direct use of combustion heat from fuel sources not suitable for direct transport and use on the vehicle. The particular concept described is also useful for a dual mode TES/liquid fuel system in which the TES (recharged from an external energy source) is used for short duration trips (approximately 10 miles or less) and liquid fuel carried on board the vehicle used for long duration trips. The dual mode approach offers the potential of 50 percent savings in the consumption of premium liquid fuels for automotive propulsion in the United States.

    2015-01-01

    The coupled model of a four-cylinder internal combustion engine and a dash panel was constructed to analyze the relationship between the engine noise and interior noise of an automobile. Finite element analysis, flexible multi-body dynamics, and boundary element analysis were integrated to obtain the tetrahedron-element models, structural vibration response, and radiated noise, respectively. The accuracy of the finite-element model of the engine was validated by modal analysis via single-input multi-output technology, while the dash panel was validated by sound transmission loss experiment. The block was optimized to reduce the radiated acoustic power from the engine surface. The acoustic transfer path between the engine cabin and passenger compartment was then established. The coupled analysis results reveal that the interior noise is optimized due to the engine noise reduction.

  16. A mathematic model of thermoelectric module with applications on waste heat recovery from automobile engine

    International Nuclear Information System (INIS)

    Over two-thirds energy of fuel consumed by an automobile is discharged to the surroundings as waste heat. The fuel usage can be more efficient if thermoelectric generators (TEG) are used to convert heat energy into electricity. In this study, a thermoelectric module composed of thermoelectric generators and a cooling system is developed to improve the efficiency of an IC engine. Two potential positions on an automobile are chosen to apply this module, e.g. exhaust pipe and radiator to examine the feasibility. To predict the behaviors of this module, a one dimensional thermal resistance model is also build, and the results are verified with experiments. The maximum power produced from the module is 51.13 mWcm-2 at 290 oC temperature difference. The model results show that, TE module presents better performance on the exhaust pipe than on the radiator.

    Volatile organic compounds (VOCs) in automobile cabins were measured quantitatively to describe their emission characteristics in relation to various idling scenarios using three used automobiles (compact, intermediate sedan, and large sedan) under three different idling conditions ([1] cold engine off and ventilation off, [2] exterior air ventilation with idling warm engine, and [3] internal air recirculation with idling warm engine). The ambient air outside the vehicle was also analyzed as a reference. A total of 24 VOCs (with six functional groups) were selected as target compounds. Accordingly, the concentration of 24 VOC quantified as key target compounds averaged 4.58 ± 3.62 ppb (range: 0.05 (isobutyl alcohol) ∼ 38.2 ppb (formaldehyde)). Moreover, if their concentrations are compared between different automobile operational modes: the 'idling engine' levels (5.24 ± 4.07) was 1.3-5 times higher than the 'engine off' levels (4.09 ± 3.23) across all 3 automobile classes. In summary, automobile in-cabin VOC emissions are highly contingent on changes in engine and ventilation modes. PMID:27261883

    1994-11-01

    The advantages/disadvantages of energy storage devices, which can provide nonpolluting automobile systems are discussed. Four types of storage devices are identified: electrochemical (batteries); hydrogen; electromechanical (flywheels); and molten salt heat storage. A high-speed flywheel with a small permanent magnet motor/generator has more advantages than any of the other systems and might become a real competitor to the internal combustion engine. A flywheel/motor/generator system for automobiles now becomes practical, because of the technological advances in materials, bearings and solid state control circuits. The motor of choice is the squirrel cage induction motor, specially designed for automobile applications. The preferred controller for the induction motor is a forced commutated cycloconverter, which transforms a variable voltage/variable frequency source into a controlled variable-voltage/variable-frequency supply. A modulation strategy of the cycloconverter elements is selected to maintain a unity input displacement factor (power factor) under all conditions of loads voltages and frequencies. The system is similar to that of the existing automobile, if only one motor is used: master controller-controller-motor-gears (fixed)-differential-wheels. In the case of two motors, the mechanical differential is replaced by an electric one: master controller-controller-motor-gears (fixed)-wheel. A four-wheel drive vehicle is obtained when four motors with their own controllers are used. 24 refs.

    Full Text Available An air flow meter for measuring the intake air of an automobile engine is presented. It is based on a miniaturized silicon thermal mass flow sensor using a thick porous Si (Po-Si layer for local thermal isolation from the Si substrate, on which the sensor active elements are integrated. The sensor is mounted on one side of a printed circuit board (PCB, on the other side of which the readout and control electronics of the meter are mounted. The PCB is fixed on a housing containing a semi-cylindrical flow tube, in the middle of which the sensor is situated. An important advantage of the present air flow meter is that it detects with equal sensitivity both forward and reverse flows. Two prototypes were fabricated, a laboratory prototype for flow calibration using mass flow controllers and a final demonstrator with the housing mounted in an automobile engine inlet tube. The final demonstrator was tested in real life conditions in the engine inlet tube of a truck. It shows an almost linear response in a large flow range between –6,500 kg/h and +6,500 kg/h, which is an order of magnitude larger than the ones usually encountered in an automobile engine.

    Laser sparks that were built with high-peak power passively Q-switched Nd:YAG/Cr4+:YAG lasers have been used to operate a Renault automobile engine. The design of such a laser spark igniter is discussed. The Nd:YAG/Cr4+:YAG laser delivered pulses with energy of 4 mJ and 0.8-ns duration, corresponding to pulse peak power of 5 MW. The coefficients of variability of maximum pressure (COVPmax) and of indicated mean effective pressure (COVIMEP) and specific emissions like hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and carbon dioxide (CO2) were measured at various engine speeds and high loads. Improved engine stability in terms of COVPmax and COVPmax and decreased emissions of CO and HC were obtained for the engine that was run by laser sparks in comparison with classical ignition by electrical spark plugs.

  4. Imaging diagnostics of ethanol port fuel injection sprays for automobile engine applications

    International Nuclear Information System (INIS)

    This paper presents characteristics of ethanol sprays at port fuel injection (PFI) conditions with variations in injection and ambient parameters. Details of temporal and spatial development of ethanol PFI sprays are studied using Mie-scattering and high-speed shadowgraph imaging techniques. Momentum flux-based injection rate measurement is also performed. The influences of fuel flow-rate, injection duration, and ambient air cross-flow are of particular interest in an effort to understand ethanol PFI spray characteristics that are relevant to automobile engines. For comparison purposes, the results from gasoline fuel are also presented. Ethanol flow-rate effects are studied using two injectors with different nozzle-hole sizes at a fixed injection pressure. From the experiments, it was found that the actual injection duration was longer for the higher flow-rate injector although an electronic pulse width was fixed. This was due to an extended delay in the injector needle closing as the flow resistance against the needle was increased for the high flow-rate injector. For liquid droplets, the larger hole size of the higher flow-rate injector caused a higher mean droplet diameter and higher number of droplets. Injection duration was also varied to study transient spray behaviour: short-injection sprays with the end-of-injection transient dominating the overall spray development were compared to long, steady-injection sprays. From Mie-scattering images, the number of droplets and mean droplet diameter were found to be less for the short injection sprays. Detailed analysis using an axial profile of the number of droplets and mean droplet diameter suggested that the observed trends were a result of increased evaporation rate near the nozzle after the end of injection. This was consistent with shadowgraph images showing no liquid regions but only the vapour-phase fuel near the nozzle. Under the influence of ambient air cross-flow, both mean droplet diameter and number of

    Full Text Available Code Recognition Device is a security device for automobiles. It responds only to the right sequence of codes that are keyed from the key pad. This closes the electrical circuitry of the automobile and enables it to start. If a wrong key is touched, it resets the device which disengages the electrical circuit of the automobile from the power supply. The device works properly on closing all the doors of the automobile, otherwise it cannot start. Also, once the automobile is in operation, opening of any door will disengage the device and the engine will stop. To restart the engine, the doors must be closed and the codes rendered sequentially-in this case the codes are 1974.

    Kim, Hwajin

    2015-04-01

    Similarities and differences in physico-chemical and optical properties of combustion generated particles from various sources were investigated. Coal-fired power plant, charcoal kiln, automobile and ship engine were major sources, representing combustions of coal, biomass and two different types of diesel, respectively. Scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDX) equipped with both SEM and HRTEM were used for physico-chemical analysis. Light absorbing properties were assessed using a spectrometer equipped with an integrating sphere. Particles generated from different combustion sources and conditions demonstrate great variability in their morphology, structure and composition. From coal-fired power plant, both fly ash and flue gas were mostly composed of heterogeneously mixed mineral ash spheres, suggesting that the complete combustion was occurred releasing carbonaceous species out at high temperature (1200-1300 °C). Both automobile and ship exhausts from diesel combustions show typical features of soot: concentric circles comprised of closely-packed graphene layers. However, heavy fuel oil (HFO) combusted particles from ship exhaust demonstrate more complex compositions containing different morphology of particles other than soot, e.g., spherical shape of char particles composed of minerals and carbon. Even for the soot aggregates, particles from HFO burning have different chemical compositions; carbon is dominated but Ca (29.8%), S (28.7%), Na(1%), and Mg(1%) are contained, respectively which were not found from particles of automobile emission. This indicates that chemical compositions and burning conditions are significant to determine the fate of particles. Finally, from biomass burning, amorphous and droplet-like carbonaceous particles with no crystallite structure are observed and they are generally formed by the condensation of low volatile species at low

  11. HPLC analysis of aldehydes in automobile exhaust gas: Comparison of exhaust odor and irritation in different types of gasoline and diesel engines

    International Nuclear Information System (INIS)

    This study investigated high performance liquid chromatography (HPLC) to identify and measure aldehydes from automobile exhaust gas. Four aldehydes: formaldehyde (HCHO), acetaldehyde (CH3CHO), acrolein (H2C=CHCHO) and propionaldehyde (CH3CH2CHO) and one ketone, acetone (CH3)2CO are separated. The other higher aldehydes in exhaust gas are very small and cannot be separated. A new method of gas sampling, hereafter called bag sampling in HPLC is introduced instead of the trapping gas sampling method. The superiority of the bag sampling method is its transient gas checking capability. In the second part of this study, HPLC results are applied to compare exhaust odor and irritation of exhaust gases in different types of gasoline and diesel engines. Exhaust odor, irritation and aldehydes are found worst in direct injection (DI) diesel engines and best in some good multi-point injection (MPI) gasoline and direct injection gasoline (DIG) engines. Indirect injection (IDI) diesel engines showed odor, irritation and aldehydes in between the levels of MPI gasoline, DIG and DI diesel engines

    Actions taken by Expert's Group WP 29 of the United Nations Economic Commission for Europe concerning the protection of the environment from automobile pollution are reported. Regulation 15, adopted by the group, establishes tests and sets limits for the amounts of carbon monoxide, hydrocarbons and nitrogen oxides emitted from internal combustion engine automobile exhaust and crankcases under urban and idling conditions. Regulation 29 specifies limits to the same pollutants emitted from diesel engines, to be determined by measurements of the opacity of exhaust fumes during constant engine operation and acceleration. Regulations limiting pollutant emissions from motorcycles and mopeds have also been established, and, while adherence to these regulations has already reduced vehicle emissions, research is continuing on stricter controls, fuel conservation, test standardization for the United States and Japan, and analysis sampling methods.

    International Nuclear Information System (INIS)

    Out of a conversion of 120 billions metric tons of fossil carbon per year 1 billion are traffic related. But this amount is growing steadily. The global automobile density is about 10 automobiles per capita. It grows with 1.7% per year, as fast as the population. The number of automobiles doubles in 25 years. In all groups of developed countries the automobile density increased from 5 to 50 automobiles per capita in less than 50 years so far. Where is the fuel for the 1 billion automobiles of the year 2030 or 2050? Can one reduce this number or what chances does one have to reduce the adverse consequences? Whatever the number of motor vehicles will be, man will have the chance to reduce fuel consumption and therefore CO2-emission together with other emissions considerably

In vapour compression refrigerant system, the system utilizes power from engine shaft as the input power to drive the compressor of the refrigeration system, hence the engine has to produce extra work to run the compressor of the refrigerating system utilizing extra amount of fuel. This loss of power of the vehicle for refrigeration can be neglected by utilizing another refrigeration system i.e. a “Vapour Absorption Refrigerant System”.

    A 6 kW (8 hp), single-cylinder, rhombic-drive Stirling engine was restored to operating condition, and preliminary characterization tests run with hydrogen and helium as the working gases. Initial tests show the engine brake specific fuel consumption (BSFC) with hydrogen working gas to be within the range of BSFC observed by the Army at Fort Belvoir, Virginia, in 1966. The minimum system specific fuel consumption (SFC) observed during the initial tests with hydrogen was 669 g/kW hr (1.1 lb/hpx hr), compared with 620 g/kWx hr (1.02 lb/hpx hr) for the Army tests. However, the engine output power for a given mean compression-space pressure was lower than for the Army tests. The observed output power at a working-space pressure of 5 MPa (725 psig) was 3.27 kW (4.39 hp) for the initial tests and 3.80 kW (5.09 hp) for the Army tests. As expected, the engine power with helium was substantially lower than with hydrogen.

  16. Corrosion protection and finishing of automobiles

    International Nuclear Information System (INIS)

    finishing of automobiles is an important aspect. There have been considerable reductions of weight in automobiles by the use of composites components replacing heavy metallic components. Fenders previously based on metal have been replaced with plastic and painted with the same colour shade as of the metallic body, this has eps for proper adhesion of the paints on the plastic fender to avoid chipping off the paint form it. This paper discusses the necessary processes required for finishing of an automobile along with the corrosion protection measures. Automobiles contains a variety of engineering materials, engine main body fuel tanks connecting rods heat radiators and other mechanical parts are made from different types of engineering alloys having varying chemical compositions. Other parts like dashboard, front panel and other are made from composites. The main body made from cold roll ed steel having various contours 'c' it due to the different designs is the potential site for corrosion attack, The main body is exposed to the hostile environment through out its life period. An automobile is given a particular finish with a view to counter the hostile environments as they are not limited for plying in a limiting conditions and are taken to different weather conditions in one day thus facing severe stresses and strain. Thus it is essential that an automobile before rolling 'out of the assembly line should properly corrosion resistant and aesthetically pleasant also. Finishing for automobiles being very specialized, the main requirement being maximum durability with minimum numbers of coats baked, at the fastest possible schedule. High gloss and range of good eye catching colours being important to increase sales appeal. In the near past the car finishes were based on alkyd-amino resins baking materials and force drying lacquers, which have excellent appearance originally and maintain it on aging. The finishing system for the synthetic baking type may consist of

    We estimate up-to-date values of the average isotopic compositions of CO emitted from automobiles. In the estimation, we determined the isotopic compositions of CO in tail pipe exhaust for four gasoline automobiles and two diesel automobiles under varying conditions of both idling and running. While the dependence on the automobile manufacturer is little, each automobile equipped with functional catalytic converter exhibits a large temporal δ13C and δ18O variation. They tend to show 13C and 18O enrichment in accordance with the reduction of CO in exhaust, suggesting that the functional catalytic converter in engines enhances the δ13C and δ18O values of CO from tail pipes through a kinetic isotope effect during CO destruction. Assuming that automobiles run a modeled driving cycle, we estimated the average δ13C and δ18O of CO to be -23.8±0.8‰ PDB and +25.3±1.0‰ SMOW, respectively, for recent gasoline automobiles, and -19.5±0.7‰ PDB and +15.1±1.0‰ SMOW, respectively, for recent diesel automobiles. While the δ13C and δ18O values of recent gasoline automobiles coincide well with the isotopic compositions of source CO in present trunk road atmosphere estimated in this study, those are +4-+6‰ ( δ13C) and +1-+3‰ ( δ18O) higher than those reported previously and also those emitted from old, non-catalyst automobiles determined in this study. Recent improvements in functional catalytic converters have enhanced and will enhance the δ13C and δ18O values of CO from automobiles.

    Slovic, P; MacGregor, D; Kraus, N N

    1987-10-01

    Descriptions of safety engineering defects of the kind that compel automobile manufacturers to initiate a recall campaign were evaluated by individuals on a set of risk characteristic scales that included overall vehicle riskiness, manufacturer's ability to anticipate the defect, importance for vehicle operation, severity of consequences and likelihood of compliance with a recall notice. A factor analysis of the risk characteristics indicated that judgments could be summarized in terms of two composite scales, one representing the uncontrollability of the damage the safety defect might cause and the other representing the foreseeability of the defect by the manufacturer. Motor vehicle defects were found to be highly diverse in terms of the perceived qualities of their risks. Location of individual defects within the factor space was closely associated with perceived riskiness, perceived likelihood of purchasing another car from the same manufacturer, perceived likelihood of compliance with a recall notice, and actual compliance rates.

  13. Analytical description of the modern steam automobile

    Science.gov (United States)

    Peoples, J. A.

    1974-01-01

    The sensitivity of operating conditions upon performance of the modern steam automobile is discussed. The word modern has been used in the title to indicate that emphasis is upon miles per gallon rather than theoretical thermal efficiency. This has been accomplished by combining classical power analysis with the ideal Pressure-Volume diagram. Several parameters are derived which characterize performance capability of the modern steam car. The report illustrates that performance is dictated by the characteristics of the working medium, and the supply temperature. Performance is nearly independent of pressures above 800 psia. Analysis techniques were developed specifically for reciprocating steam engines suitable for automotive application. Specific performance charts have been constructed on the basis of water as a working medium. The conclusions and data interpretation are therefore limited within this scope.

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

  4. Environmental implications of the automobile

    International Nuclear Information System (INIS)

    There are over 12 million automobiles in Canada, each travelling over 16,000 km annually. The value of motor vehicles and parts produced in Canada accounts for over 6% of the gross domestic product, and vehicle-related sales account for the largest proportion of Canadian retail activity. The environmental issues related to the high impact of the automobile on Canadian life are discussed. In the manufacture of motor vehicles, over 2 billion kg of metal are used a year; although much of this comes from recycled materials, some depletion of nonrenewable resources is required. It is also estimated that 66-105 GJ of energy are needed to produce a motor vehicle, equivalent to as much as 20% of all the energy consumed during the vehicle's lifetime. Environmental impacts result from this use of resources and energy, including land disturbances and air pollution. Land use impacts are also those related to appropriation of urban and rural land for roadway and service uses, plus pollution of adjoining lands by road runoff. In 1990, the transportation sector used 29% of end-use energy, of which retail gasoline sales for motor vehicles accounted for 54%. Environmental impacts from oil refining, fuel combustion, and waste disposal are described, and programs to mitigate these impacts are outlined. Significant reductions in automobile emissions have already occurred from the increased use of emission control devices, improved fuel efficiency, and stricter standards. Further improvements are possible via such means as better manufacturing procedures, increased recycling of automobile components, better inspection and maintenance, and use of alternative fuels and alternate transportation modes. 35 refs., 3 figs., 4 tabs

    Barbusse, St.; Gagnepain, L.

    2003-05-01

    Over the last three decades, automobile manufacturers have made a lot of progress in specific fuel consumption and engine emissions of pollutants. Yet the impact of these improvements on vehicle consumption has been limited by increased dynamic performances (maxi-mum speed, torque), increased safety (power steering and power brakes) and increased comfort (noise and vibration reduction, electric windows and thermal comfort). Because of this, the real CO{sub 2}-emission levels in vehicles is still high in a context where road transport is a major factor in the balance sheet of greenhouse gas emissions, thus in complying with the inter-national climate convention. Although European, Japanese and Korean manufacturers signed an important agreement with the European Commission for voluntarily reducing CO{sub 2} emissions from their vehicles, with a weighted average emission goal by sales of 140 grams per km on the MVEG approval cycle by 2008, it has to be noted that the European procedures for measuring fuel consumption and CO{sub 2} emissions do not take accessories into account, especially air-condition ng (A/C). The big dissemination of this equipment recognized as a big energy consumer and as using a refrigerant with a high global warming potential ed ADEME to implement a set of assessments of A/C's energy and environmental impact. In particular these assessments include studies of vehicle equipment rates, analyses of impact on fuel consumption as well as regulated pollutant emissions in the exhaust, a characterization of the refrigerant leakage levels and an estimate of greenhouse gas emissions for all air-conditioned vehicles. This leaflet summarizes the results of these actions. All of these studies and additional data are presented in greater detail in the document,-'Automobile Air-conditioning' (ADEME reference no. 4985). (author)

    We studied the information search behaviors of Chinese consumers of miniature automobiles. First, we identified the main sources where consumers acquire or seek information about miniature automobiles and discussed their extent of information search. Then, based on logistic regression and optimal scaling regression of statistics, we studied the influences of characteristics of consumers of miniature automobiles on the extent of information search and on Internet usage. The results indicate that consumers often utilize four sources to obtain information about miniature automobiles. The dominant information source for consumers is their friends/family, followed by dealers, newspapers, and TV. Age, occupation, education and income significantly affect the extent of information search, but gender and city of residence do not have significant impacts. Age, city of residence, occupation, education and income produce significant influences on Internet usage. Gender has an insignificant influence on whether a consumer uses the Internet to search for information.

  7. Life cycle models of conventional and alternative-fueled automobiles

    Science.gov (United States)

    Maclean, Heather Louise

    This thesis reports life cycle inventories of internal combustion engine automobiles with feasible near term fuel/engine combinations. These combinations include unleaded gasoline, California Phase 2 Reformulated Gasoline, alcohol and gasoline blends (85 percent methanol or ethanol combined with 15 percent gasoline), and compressed natural gas in spark ignition direct and indirect injection engines. Additionally, I consider neat methanol and neat ethanol in spark ignition direct injection engines and diesel fuel in compression ignition direct and indirect injection engines. I investigate the potential of the above options to have a lower environmental impact than conventional gasoline-fueled automobiles, while still retaining comparable pricing and consumer benefits. More broadly, the objective is to assess whether the use of any of the alternative systems will help to lead to the goal of a more sustainable personal transportation system. The principal tool is the Economic Input-Output Life Cycle Analysis model which includes inventories of economic data, environmental discharges, and resource use. I develop a life cycle assessment framework to assemble the array of data generated by the model into three aggregate assessment parameters; economics, externalities, and vehicle attributes. The first step is to develop a set of 'comparable cars' with the alternative fuel/engine combinations, based on characteristics of a conventional 1998 gasoline-fueled Ford Taurus sedan, the baseline vehicle for the analyses. I calculate the assessment parameters assuming that these comparable cars can attain the potential thermal efficiencies estimated by experts for each fuel/engine combination. To a first approximation, there are no significant differences in the assessment parameters for the vehicle manufacture, service, fixed costs, and the end-of-life for any of the options. However, there are differences in the vehicle operation life cycle components and the state of technology

  9. Environmental implications of alternative-fueled automobiles: Air quality and greenhouse gas tradeoffs

    International Nuclear Information System (INIS)

    The authors analyze alternative fuel-powerstrain options for internal combustion engine automobiles. Fuel/engine efficiency, energy use, pollutant discharges, and greenhouse gas emissions are estimated for spark and compression ignited, direct injected (DI), and indirect injected (II) engines fueled by conventional and reformulated gasoline, reformulated diesel, compressed natural gas (CNG), and alcohols. Since comparisons of fuels and technologies in dissimilar vehicles are misleading, the authors hold emissions level, range, vehicle size class, and style constant. At present, CNG vehicles have the best exhaust emissions performance while DI diesels have the worst. Compared to a conventional gasoline fueled II automobile, greenhouse gases could be reduced by 40% by a DI CNG automobile and by 25% by a DI diesel. Gasoline- and diesel-fueled automobiles are able to attain long ranges with little weight or fuel economy penalty. CNG vehicles have the highest penalty for increasing range, due to their heavy fuel storage systems, but are the most attractive for a 160-km range. DI engines, particularly diesels, may not be able to meet strict emissions standards, at least not without lowering efficiency

    Since the automobile turbochargers are installed in an engine compartment with limited space, the ducts upstream of the turbocharger compressor may be curved in a complex manner. In the present paper, the effect of a curved duct upstream on performance of small centrifugal compressors for automobile turbochargers is discussed. The computational fluid dynamics (CFD) analysis of a turbocharger compressor validated for the compressor model with the straight pipe applied to the compressor with the curved pipe are executed, and the deterioration of the performance for the curved pipe is confirmed. It is also found that the deterioration of compressor performance is caused by the interaction of the secondary flow and the impeller.

    2015-01-01

    Controller area networks (CANs) have been designed for multiplexing communication between electronic control units (ECUs) in vehicles and many high-level industrial control applications. When a CAN bus is overloaded by a large number of ECUs connected to it, both the waiting time and the error probability of the data transmission are increased. Thus, it is desirable to reduce the CAN frame length, since the duration of data transmission is proportional to the frame length. In this paper, we present a CAN message compression method to reduce the CAN frame length. Experimental results indicate that CAN transmission data can be compressed by up to 81.06%with the proposed method. By using an embedded test board, we show that 64-bit engine management system (EMS) CAN data compression can be performed within 0.16 ms;consequently, the proposed algorithm can be successfully used in automobile applications.

    2008-01-01

    Full Text Available With the advancement of digital signal processing technologies, consumers are more concerned with the quality of multimedia entertainment in automobiles. In order to meet this demand, an audio enhancement system is needed to improve bass reproduction and cancel engine noise in the cabins. This paper presents an integrated active noise control system that is based on frequency-sampling filters to track and extract the bass information from the audio signal, and a multifrequency active noise equalizer to tune the low-frequency engine harmonics to enhance the bass reproduction. In the noise cancellation mode, a maximum of 3 dB bass enhancement can be achieved with significant noise suppression, while higher bass enhancement can be achieved in the bass enhance mode. The results show that the proposed system is effective for solving both the bass audio reproduction and the noise control problems in automobile cabins.

    During this PhD, we have developed an optical technique based on radicals fluorescence. The objective was to obtain more information on combustion phenomena. We first have applied the OH and HCHO PLIF technique simultaneously in laminar premixed counter-flow flames under pressure. With this technique, we have obtained the local heat release rate of the flame and an estimation of the laminar flame speed and the thickness of the flame for different fuels and pressure. We have then applied this technique on a Diesel fuel jet in combustion placed in a high pressure cell to understand the different phenomena occurring. Then PLIF at 355 nm was applied in direct and indirect injection spark ignition engine to detect the unburned. We have demonstrated the high potential of the technique used during this PhD to obtain local heat release rate of a flame. We have also progressed in our comprehension of the phenomena occurring during the combustion processes. (author)

Para o levantamento de informações sobre as EPs adotadas, entrevistas semiestruturadas foram feitas com pelo menos um dos principais responsáveis - gerentes - pela unidade produtora de motores em cada empresa. Observou-se que as EPs adotadas pelas empresas são distintas entre os grupos e em cada grupo (intragrupos, marcadas por diferenças nas áreas de decisão estruturais, apesar de haver semelhanças entre as estratégias competitivas das empresas em cada grupo (estabelecidas e entrantes. Alguns dos resultados encontrados nesta pesquisa confirmam proposições da literatura, outros indicam que há temas que precisam ainda ser cuidadosamente investigados.The operations strategies adopted by six engine assemblers between 2005 and 2006 in Brazil were identified and analyzed. Three of them started their operations some decades ago and were, therefore, denominated "established firms". The other three have started their operations only after the 1990s and were denominated "entrant firms". Information on the adopted strategies was gathered through interviews with at least one of the main managers in each engine assembly plant investigated. We observed that the adopted operations strategies are different in terms of inter and intra groups of those plants. The distinct characteristics of operations strategies are mainly due to differences in structural decision areas although the competitive strategies in each group have some common traces.

    Full Text Available Le mauvais rendement énergétique des véhicules utilisés à très faible charge (circulation urbaine, vitesses limitées provient entre autres des combustions non optimales. Celles-ci sont de plusieurs types : combustion lente et/ou tardive, ratés de propagation. L'acquisition de cycles de pression au moyen du système DIGITAP développé à l'In-titut Français du Pétrole (IFP est décrite et le calcul instantané du travail cycle-à-cycle permet de définir un critère de stabilité de fonctionnement du moteur. L'analyse thermodynamique des cycles montre que la composition du mélange air + carburant + gaz résiduels, trop proche des limites de propagabilité de flamme, est à l'origine des phénomènes observés. Des voies d'action portant sur les gaz résiduels, la turbulence et les paramètres du système d'allumage sont dégagées et permettent des améliorations importantes du rendement. The poor energy efficiency of vehicles used at very low engine load (urban traffic, limited speeds comes from non-optimum combustion, among other causes. Such combustion may be of several types, i. e. slow and/or late combustion, propagation misfiring. The recording of pressure cycles by the DIGITAP system developed at Institut Français du Pétrole (IFP is described, and the instantaneous computing of the cycle-to-cycle work enables a stability criterion for engine operating to be described. The thermodynamic analysis of the cycles shows that the composition of the air + fuel + residuel gas mixture which is too close to flame propagation limits is at the origin of the phenomena observed. Methods of action concerning residual gases, turbulence and the parameters of the ignition system are determined and make for great improvements in efficiency and stability for such types of running.

    Commercial fuels contain a multitude of chemical compounds. Their incomplete combustion in car engines leads to pollutants emission. The aim of this study is to improve our knowledge of oxidation kinetic mechanisms at high temperature for aromatic hydrocarbons because of their importance in fuels composition. Kinetics of benzene, toluene, ethyl-benzene and styrene combustion was studied, at equivalence ratio in the range 0.5 to 1.5, by means of two experimental apparatus: a jet-stirred reactor (JSR) and a shock tube (ST). In the JSR, reactive mixtures, diluted by N{sub 2}, were oxidized at atmospheric pressure in the temperature range 950 to 1400 K. Concentration profiles of sampled stable species were measured, at a steady residence time, by gas chromatography (GC/MS, GC/FID/TCD). In the ST, temperature and pressure ranges were higher: 1300 < T(K) < 2000, 1 < P(bar) < 20. Ignition delays were measured by recording OH emission profiles at 306 nm. A detailed kinetic reaction mechanism for the oxidation of aromatic hydrocarbons at high temperature was proposed. This mechanism includes 936 reactions and 125 species. It's based on the kinetic scheme of Ristori et al. (2001),It was further validated in the present work by modeling the ignition of benzene and toluene. Ethyl-benzene and styrene sub-mechanisms were developed. The agreement between the simulations and JSR experimental data is satisfactory. The ignition delays are well simulated. However, the modeling of concentration profiles needs improvements: defaults in the mechanism of benzene have repercussions on the predicted reactivity of ethyl-benzene and styrene which is higher than observed in the experiments.

  2. The promise of fuel cell-based automobiles

    Indian Academy of Sciences (India)

    A K Shukla; C L Jackson; K Scott

    2003-02-01

    Fuel cell-based automobiles have gained attention in the last few years due to growing public concern about urban air pollution and consequent environmental problems. From an analysis of the power and energy requirements of a modern car, it is estimated that a base sustainable power of $ca$. 50 kW supplemented with short bursts up to 80 kW will suffice in most driving requirements. The energy demand depends greatly on driving characteristics but under normal usage is expected to be 200 Wh/km. The advantages and disadvantages of candidate fuel-cell systems and various fuels are considered together with the issue of whether the fuel should be converted directly in the fuel cell or should be reformed to hydrogen onboard the vehicle. For fuel cell vehicles to compete successfully with conventional internal-combustion engine vehicles, it appears that direct conversion fuel cells using probably hydrogen, but possibly methanol, are the only realistic contenders for road transportation applications. Among the available fuel cell technologies, polymer–electrolyte fuel cells directly fueled with hydrogen appear to be the best option for powering fuel cell vehicles as there is every prospect that these will exceed the performance of the internal-combustion engine vehicles but for their first cost. A target cost of $ 50/kW would be mandatory to make polymer–electrolyte fuel cells competitive with the internal combustion engines and can only be achieved with design changes that would substantially reduce the quantity of materials used. At present, prominent car manufacturers are deploying important research and development efforts to develop fuel cell vehicles and are projecting to start production by 2005.

  5. PRODUCT EFFICIENCY IN THE SPANISH AUTOMOBILE MARKET

    Directory of Open Access Journals (Sweden)

    González, Eduardo

    2013-01-01

    Full Text Available This paper evaluates product efficiency in the Spanish automobile market. We use non parametric frontier techniques in order to estimate product efficiency scores for each model. These scores reflect the minimum price for which each car could be sold, given the bundle of tangible features it offers in comparison to the best-buy models. Unlike previous research, we use discounted prices which have been adjusted by car dealerships to meet sale targets. Therefore, we interpret the efficiency scores as indicators of the value of the intangible features of the brand. The results show that Audi, Volvo, Volkswagen and Mercedes offer the greatest intangible value, since they are heavily overpriced in terms of price/product ratios. Conversely, Seat, Kia, Renault and Dacia are the brands that can be taken as referent in terms of price/product ratios.

  6. Optimization of Thermoelectric Components for Automobile Waste Heat Recovery Systems

    Science.gov (United States)

    Kumar, Sumeet; Heister, Stephen D.; Xu, Xianfan; Salvador, James R.

    2015-10-01

    For a typical spark ignition engine approximately 40% of available thermal energy is lost as hot exhaust gas. To improve fuel economy, researchers are currently evaluating technology which exploits exhaust stream thermal power by use of thermoelectric generators (TEGs) that operate on the basis of the Seebeck effect. A 5% improvement in fuel economy, achieved by use of TEG output power, is a stated objective for light-duty trucks and personal automobiles. System modeling of thermoelectric (TE) components requires solution of coupled thermal and electric fluxes through the n and p-type semiconductor legs, given appropriate thermal boundary conditions at the junctions. Such applications have large thermal gradients along the semiconductor legs, and material properties are highly dependent on spatially varying temperature profiles. In this work, one-dimensional heat flux and temperature variations across thermoelectric legs were solved by using an iterative numerical approach to optimize both TE module and TEG designs. Design traits were investigated by assuming use of skutterudite as a thermoelectric material with potential for automotive applications in which exhaust gas and heat exchanger temperatures typically vary from 100°C to over 600°C. Dependence of leg efficiency, thermal fluxes and electric power generation on leg geometry, fill fractions, electric current, thermal boundary conditions, etc., were studied in detail. Optimum leg geometries were computed for a variety of automotive exhaust conditions.

  7. Automobile exhausts as a source for the environmental pollution by polychloro-dibenzodioxins and -dibenzofurans

    International Nuclear Information System (INIS)

    This research project was focussed on the analysis of polyhalogenated dibenzodioxins (''dioxins'') and dibenzofurans (''furans'') emitted through automobile exhausts (halogen = chlorine or bromine). High-resolution selective capillary gas chromatography coupled with mass-selective detection was used. The two compound groups show basic differences in pattern and concentrations for traffic-related samples. In the ''dioxin''-series the higher-chlorinated dibenzodioxins (increasing from Cl4 to Cl8) are preferentially found, in contrast to the ''furane'', present in higher amounts, for which the lower-halogenated dibenzofurans are more important (decreasing from Cl1 to Cl6 and from Br1 to Br4). The distribution of the dioxin- and furan isomers produced corresponds closely to the so-called ''2,6-type'' pattern which is due to a retarded oxidation and/or a stabilization of phenoxy-intermediates containing the 2,6- or 2,4,6-substitution pattern. To what extent a particular dioxin/furan immission is due to automobile-related emissions can, in the light of the present results, be estimated only by taking several factors into account; source remoteness, the predominance of brominated or partly brominated dibenzofurans over the chlorinated congeners, the presence of other, also halogenated, polycyclic aromatics related to the automobile combustion engine. Areas close to traffic are primarily or completely influenced by the ''dioxin''-emissions of automobiles. For the calculation of the toxic equivalents (TE) for traffic-related emissions, the most important of the ''2,3,7,8''-substituted congeners are the furans 2,3,7,8-Cl4DF (F 83) and 2,3,4,7,8-Cl5DF (F 114) as well as the dioxins 1,2,3,4,6,7,8-Cl7DD (D 73) and octachlorodibenzodioxin (D-75).

It is obvious that automobile-dependent urban development is under heavy/powerful influence of the automobile lobby (automobile and oil industries, along with construction. In this domain famous land-use-transportation studies (or ‘grand transportation studies’ are, unfortunately, still prevailing - a vicious circle of self-fulfilling prophecy of congestion, road building, sprawl, congestion and more road building. Until recently, it was commonly thought that investment in public transport was not economically sustainable and that focusing on the development of the automobile industry and financing the construction of roadways stimulated economic growth. In this paper we clearly show that automobile industry is now overcapitalized, less profitable than many other industries (and may become even less profitable in the future, that transport market is characterized with huge distortions (more than a third of motor-vehicle use can be explained by underpriced driving, while new road investment does not have a major impact on economic growth (especially in a region with an already well-developed infrastructure, and that pro-automobile transport strategy inexorably incurs harmful global, regional and local ecological consequences.

  9. Consumer preferences for automobile energy-efficiency grades

    International Nuclear Information System (INIS)

    Recently, increases in energy prices have made energy conservation and efficiency improvements even more essential than in the past. However, consumers experience difficulty in obtaining reliable information regarding energy efficiency, so that many countries have implemented regulations to enforce energy-efficiency grade labeling. In this study, consumer preferences regarding energy efficiency grades are analyzed by the mixed logit and MDCEV model based on the revealed preference data of past automobile purchases. Findings show that consumers rationally apply information on energy efficiency grades when purchasing automobiles. However, they tend to show inefficiency in automobile usage patterns. This study discusses political implications of energy efficiency policies as they might impact consumer behaviors of automobile purchase and usage. - Highlights: ► We model discrete choice model to evaluate energy-efficiency grade regulation. ► Consumers apply information on energy efficiency grades when purchasing automobiles. ► However, they tend to show inefficiency in automobile usage patterns. ► The policies for efficient automobile usage are discussed.

  3. Exposure to emissions from gasoline within automobile cabins

    International Nuclear Information System (INIS)

    Gasoline is emitted from automobiles as uncombusted fuel and via evaporation. Volatile organic compounds (VOC) from gasoline are at higher levels in roadway air than in the surrounding ambient atmosphere and penetrate into automobile cabins, thereby exposing commuters to higher levels than they would experience in other microenvironments. Measurements of VOC concentrations and carbon monoxide were made within automobiles during idling, while driving on a suburban route in New Jersey, and on a commute to New York City. Concentrations of VOC from gasoline were determined to be elevated above the ambient background levels in all microenvironments while VOC without a gasoline source were not. The variability of VOC concentrations with location within the automobile was determined to be smaller than inter-day variability during idling studies. VOC and carbon monoxide levels within the automobile cabin differed among the different routes examined. The levels were related to traffic density and were inversely related to driving speed and wind speed. Overall, daily VOC exposure for gasoline-derived compounds during winter commuting in New Jersey was estimated to range between 5 and 20% and constituted between 15 and 40% of an individual's daily exposure based on comparison to urban and suburban settings, respectively. VOC exposure during commuting in Southern California was estimated to range between 15 and 60%

    Automobile tyre lateral runout is one of the important indexes to measure the quality of the tyre, it will affect the safety of the automobile in moving. This paper introduces a sensor for automobile tyre lateral runout measurement. The variation of the automobile tyre lateral runout causes the change of guide rod probe displacement and deforms of the cantilever beam which connects with the guide bar. The deformation of the cantilever beam leads to the change of the resistance value of strain gauge which is pasted on the cantilever beam. Through measuring circuit, the resistance value of the strain gauge is converted into output voltage that has a certain relationship with automobile tyre lateral runout. Then, the voltage signal is transformed by A/D convertor and send to SCM to process and display the value of runout. Meanwhile, SCM output control signal to control the actuator and adjust the equipment running status in real time so as to ensure the tyre lateral runout is within the allowed range.

    The air pollution coming from automobile is responsible of different diseases in respiratory or cardiovascular system. epidemiological studies in professional or general media give information in term of public health. If the role of air pollution from automobile at short terms is well established, for effects at long term (such cancers or chronic diseases of respiratory system) the measurement or estimation of the exposure is not sufficient for the moment and makes the epidemiology unable to quantify effects. In spite of these lacks, it is important to reduce the risk for the most fragile people. (N.C.)

  20. Development of amorphous wire type MI sensors for automobile use

    Science.gov (United States)

    Honkura, Yoshinobu

    2002-08-01

    Amorphous wire type MI sensors have a high sensitivity compared to thin film MI sensors, but there have been reliability problems in developing an amorphous wire type MI sensor for automobile application because of the wide range of operating temperatures. It was difficult to achieve sufficient soldering strength between the amorphous wire and the electrode of the MI chip. In addition, stress is induced in the amorphous wire during soldering thus lowering the temperature stability characteristics. Therefore, we developed a new method for soldering the amorphous wire and a new method for assembly of the MI chip. Together with the redesign of the electronic circuit, these developments have yielded an MI sensor suitable for automobile application. This MI sensor has a sensitivity of 250 mV/Oe, has stable temperature characteristics between -40°C and 85°C and easily passed the thermal shock test, the most stringent durability test for automobile electronic parts. Two different types of products are under development; one is a standard type whose output is linear to the external magnetic field, and the other is a switch type whose output is ON or OFF relative to a threshold magnetic field. Future applications include an ABS sensor, an electronic compass, an automatic tracking system for automobiles and so on.

  13. The growing interest of automobile manufacturers for natural gas as an automotive fuel

    International Nuclear Information System (INIS)

    The prospects for natural gas vehicles (NGV) are good. The number of trucks, busses and passenger cars that run on natural gas has considerably increased over the last few years. Natural gas is applauded from various sides as the most important alternative engine fuel. Some prestigious automobile manufacturers have meanwhile included NGV in their price list. However, it's up to the authorities and the gas industry itself in particular to make or break the success of NGV. The maximum range of 300 km is still too limited as is the number of natural gas filling stations in most countries. And without financial impetus NGV will not be able to compete with petrol- and diesel-fueled cars. Yet, clean natural gas vehicles appear to realize a market share of 1% soon

    Analyses were performed on change in living body information as time elapses while driving a car, the differences between automobile drivers and fellow passengers, and between automobile drivers and motorcycle drivers. A comparison on body temperatures in automobile drivers and motorcycle drivers shows sharper changes in the motorcycle drivers. Motorcycles, being different from automobiles, put the drivers exposed to atmosphere during driving, applying larger living body load. Adrenalin increases its concentration when a human is under mental load, so does noradrenalin when under physical load. Both of adrenalin and noradrenalin showed an increasing trend in the afternoon as compared with in the morning. From the comparison with the normal daily life, fellow passengers have also large mental living body load, who were found to have concentration change of nearly two times or more than that in normal conditions. A subject who rode in a car in the first experiment and drove a motorcycle in the second experiment was discovered to have his right hand grasping power decreased remarkably after the second experiment. Fatigue factors unique to motorcycle driving are thought the engine vibration, the hot air, the need of taking balance of the motorcycle attitudes, and stress from noise. 14 refs., 8 figs.

    An FE analysis procedure was presented to predict the behavior of soil-geogrid interaction under automobile loading. The dynamic interactions between the transverse bars, the longitudinal ribs and the soil were simulated by a system consisting of nonlinear springs, dashpots and masses, to study the deformation properties of the reinforced soil. The equivalent stiffness and damping ratios could be determined with the shaking table. The dynamic responses of a reinforced subgrade were analyzed with the 3D finite element approach. This approach is programmed and applied to analyze the soil-geogrid interaction under dynamic loading. The comparative analysis of the response of the reinforced subgrade and that of the subgrade without reinforcement shows that the geogrid placed at the bottom of the base layer may effectively reduce the accumulative plastic deformation due to the cyclic automobile loading.

    As part of an overall study to evaluate the usefulness of ride quality criteria for the design of improved ground transportation systems an experiment was conducted involving subjective and objective measurement of ride vibrations found in an automobile riding over roadways of various roughness. Correlation of the results led to some very significant relationships between passenger rating and ride accelerations. The latter were collapsed using a frequency-weighted root mean square measure of the random vibration. The results suggest the form of a design criterion giving the relationship between ride vibration and acceptable automobile ride quality. Further the ride criterion is expressed in terms that relate to rides with which most people are familiar. The design of the experiment, the ride vibration data acquisition, the concept of frequency weighting and the correlations found between subjective and objective measurements are presented.

    A model substance was used which is similar in respect to platinum content of exhaust particles emitted from a three-way-catalytic converter equipped engine. The bioavailability of platinum from such exhaust particles and the kind of platinum species formed in vivo were assessed. An in vitro solubility test showed a solubility of approximately 10 percent of platinum content of the model substance in physiological sodium chloride solution. Two short-term animal studies (8 days) were performed. In all examined rat tissues and body fluids platinum could be detected. In addition, the contribution of the overall bioavailability caused by swallowing a certain amount of the intratracheally applied platinum was evaluated by oral application. It was very low. An analytical method was developed to determine platinum species. Synthetic samples (matrix with a platinum standard solution) were analysed. In rat bronchoalveolar lavage spiked with a platinum standard solution only low molecular complexed platinum was found whereas in rat blood plasma all platinum was bound to proteins. In ongoing studies, the model substance is being tested in a three month rat inhalation study. PMID:9820662

  7. Globalization of the automobile industry in China: dynamics and barriers in greening of the road transportation

    International Nuclear Information System (INIS)

    This article describes the state of the automobile industry and urban road transportation management in China. It reviews how the automobile industry is evolving to respond to challenges in economic development, environmental regulations, and technological change. The dynamics and barriers resulting from technological change of automobiles in response to reduction of exhaust emissions and energy-efficiency improvement are analyzed. It is argued that consideration of externality costs should be integrated in automobile industrial policymaking and transportation management. Efforts need to be made to use more economic incentives for emissions reduction, and to promote technological change for cleaner vehicle development. This paper questions the current government policy of encouraging private car ownership, and suggests that improvement in public transportation systems, stronger emissions control, and technology innovation on environmental friendly automobile technologies would be relevant to China's drive toward sustainable transportation development. Social inequities resulted from automobile use is also stressed in the analysis

    Urmetzer, P.; Blake, D. E.; Guppy, N. [British Columbia Univ., Vancouver, BC (Canada)

    1999-09-01

    Air pollution associated with motor vehicle use is one of the prime indicators of the tension between consumerism and the environment. The use of private automobiles seems so convenient, whereas the alternatives are off-putting enough to make significant changes in personal transportation behaviour well-nigh impossible. At the same time, combating the air pollution associated with extensive use of cars has become one of the major policy objectives for cities around the world. Available policy alternatives can be divided into two categories: (1) incentives, such as improved public transportation, and (2) disincentives, such as environmental tax on gasoline. This paper attempt to directly assess links between these two alternatives, associated attitudes towards them, the level of public support for command and control (i.e. regulatory) policy approaches as well as for economic incentive/disincentive policies. Answers are sought and findings discussed relative to the link between opinions about the environment and support for different types of environmental policies, the usefulness of a rational choice perspective in explaining support for environmental policy alternatives, the role that partisan political attachments play in support of environmental policy approaches, and the roles played by environmental activism, knowledge, and action in shaping support for environmental policy alternatives. Overall results indicate that while most people living in urban environments support the ideas of environmental protection and would be willing to incur costs to confront the problem, exposure to air pollution plays an inconsequential (actually nearly non-existent) role in support of automobile-related environmental problems. Automobile users act like 'free-riders' i.e. they tend to support policies that socialize the cost of solutions rather than policies that attempt to pass the cost of pollution directly on to individual car owners.

    Full Text Available Introduction: traffic accidents are one of the main causes of death and disability, with motorcyclists representing the great majority of both the victims and the perpetrators. Objective: this work studied the characteristics of motorcyclists injured in accidents involving motorcycles and automobiles. Method: this study sought to interview 100 motorcyclists who had been injured in collisions between motorcycles and automobiles, and who were undergoing emergency hospital treatment in the region of Belo Horizonte, Brazil. The questionnaires included demographic information (age, gender, skin color, education level, profession and questions about years of licensed driving practice, how often they would drive an automobile, how long they had had a motorcycle driver’s license, how often they would ride a motorcycle, the number of prior accidents involving a car, and the number of prior accidents not involving a car. Results: of the 100 consecutive accidents studied, 91 occurred with men and 9 with women, aged between 16 and 79 (m = 29 ± 11 years. Regarding their reason for using a motorcycle, 83% reported using it for transport, 7% for work, and 10% for leisure. Most of these accident victims had secondary or higher education (47%. Of the motorcyclists who held a car driver’s license, 68.3% drove the vehicle daily or weekly and held the license for more than one year. Sixty-seven percent of the accident victims used a motorcycle daily and had a motorcycle driver’s license for at least one year. Conclusion: among the motorcyclists injured, most were men aged 20 years or older, with complete secondary education, and experienced in driving both motorcycles and cars, indicating that recklessness while driving the motorcycle is the main cause of traffic accidents.

By contrast, an “EV society” is a concept whereby EVs are more fundamentally woven into the fabric of society with the aim of solving a range of social problems, while at the same time questioning the meaning of what an automobile “is” and “can be.” It is this “game-changing” principle of integration that drives our research.

  7. Phenols and nitrophenols as tropospheric pollutants: emissions from automobile exhausts and phase transfer in the atmosphere

    International Nuclear Information System (INIS)

    Motor exhaust gas from an automobile motor, operated under stationary conditions with unleaded gasoline, was sampled with two different impinger bath methods. The samples were analyzed by gas chromatography/mass spectrometry (GC/MS) for phenol, cresols and nitrated phenols. Phenol and cresols were measured in the range of 80 - 220 nmol/L of exhaust gas from a noncatalyst engine, and nitrated phenols were found in the range of 9-36 nmol/L. A large reduction of total phenols down to 7% and less was observed when the engine was operated with a regulated three-way catalytic converter. The result of this study shows that exhaust gas sampling of phenols with alkaline aqueous impinger solutions leads to an underestimation of phenol emissions, since phenols are not stable under high-pH conditions. In order to better assess the environmental fate of nitrated phenols, laboratory experiments were conducted to measure the Henry's law constants of a series of nitrated phenols. For that purpose an apparatus for dynamic determination of the Henry's law constants was constructed and successfully used. Special emphasis was put on temperature dependence of the Henry's law constants. 15 refs., 2 figs., 2 tabs

    2016-06-01

    Full Text Available Asbestos has been used for so long as automobile brake lining material because of its good physical and chemical properties. However, due to the health hazard associated with its handling, it has lost favour and several alternative materials are being increasingly used. Asbestos-free brake lining was developed in this work using pulverized cow hooves along with epoxy resin, barium sulphate, graphite and aluminium oxide. This was with a view to exploiting the characteristics of cow hooves, which are largely discarded as waste materials to replace asbestos which has been found to be carcinogenic. Samples of brake linings were produced using compressive moulding in which the physical and mechanical properties of the samples were studied. The results obtained showed that proper bonding was achieved as the percentage by weight of epoxy resin increased and percentage by weight of pulverized cow hooves decreased. The hardness, compressive strength, coefficient of friction, water and oil absorption, relative density and wear rate of the brake linings were determined and compared with existing brake lining properties. The result indicates that pulverized cow hooves can be used as brake lining material for automobiles.

    Kagawa, Noboru

    Recent advances in the feasibility studies related to the Stirling engines and Stirling engine heat pumps which have been considered attractive due to their promising role in helping to solve the global environmental and energy problems,are reviewed. This article begins to describe the brief history of the Stirling engines and theoretical thermodynamic analysis of the Stirling cycle in order to understand several advantages on the Stirling engine. Furthermore,they could throw light on our question why the dream engines had not been promoted to practical applications during two hundred years. The present review shows that the Stirling engines with several unique advantages including 30 to 40% thermal efficiency and preferable exhaust characteristics,had been designed and constructed by recent tackling for the development of the advanced automobile and other applications using them. Based on the current state of art,it is being provided to push the Stirling engines combined with heat pumps based on the reversed Rankine cycle to the market. At present,however, many problems, especially for the durability, cost, and delicate engine parts must be enforced to solve. In addition,there are some possibilities which can increase the attractiveness of the Stirling engines and heat pumps. The review closes with suggestions for further research.

    Maravas, Alexander; Stengel, Robert F.

    1994-01-01

    Transportation network capacity variations arising from accidents, roadway maintenance activity, and special events as well as fluctuations in commuters' travel demands complicate traffic management. Artificial intelligence concepts and expert systems can be useful in framing policies for incident detection, congestion anticipation, and optimal traffic management. This paper examines the applicability of intelligent route guidance and control as decision aids for traffic management. Basic requirements for managing traffic are reviewed, concepts for studying traffic flow are introduced, and mathematical models for modeling traffic flow are examined. Measures for quantifying transportation network performance levels are chosen, and surveillance and control strategies are evaluated. It can be concluded that automated decision support holds great promise for aiding the efficient flow of automobile traffic over limited-access roadways, bridges, and tunnels.

    2007-01-01

    As point cloud of one whole vehicle body has the traits of large geometric dimension, huge data and rigorous reverse precision, one pretreatment algorithm on automobile body point cloud is put forward. The basic idea of the registration algorithm based on the skeleton points is to construct the skeleton points of the whole vehicle model and the mark points of the separate point cloud, to search the mapped relationship between skeleton points and mark points using congruence triangle method and to match the whole vehicle point cloud using the improved iterative closed point (ICP) algorithm. The data reduction algorithm, based on average square root of distance, condenses data by three steps, Computing datasets' average square root of distance in sampling cube grid, sorting order according to the value computed from the first step, choosing sampling percentage. The accuracy of the two algorithms above is proved by a registration and reduction example of whole vehicle point cloud of a certain light truck.

  13. Maximum Power Point Tracking with Dichotomy and Gradient Method for Automobile Exhaust Thermoelectric Generators

    Science.gov (United States)

    Fang, W.; Quan, S. H.; Xie, C. J.; Tang, X. F.; Wang, L. L.; Huang, L.

    2016-03-01

    In this study, a direct-current/direct-current (DC/DC) converter with maximum power point tracking (MPPT) is developed to down-convert the high voltage DC output from a thermoelectric generator to the lower voltage required to charge batteries. To improve the tracking accuracy and speed of the converter, a novel MPPT control scheme characterized by an aggregated dichotomy and gradient (ADG) method is proposed. In the first stage, the dichotomy algorithm is used as a fast search method to find the approximate region of the maximum power point. The gradient method is then applied for rapid and accurate tracking of the maximum power point. To validate the proposed MPPT method, a test bench composed of an automobile exhaust thermoelectric generator was constructed for harvesting the automotive exhaust heat energy. Steady-state and transient tracking experiments under five different load conditions were carried out using a DC/DC converter with the proposed ADG and with three traditional methods. The experimental results show that the ADG method can track the maximum power within 140 ms with a 1.1% error rate when the engine operates at 3300 rpm@71 NM, which is superior to the performance of the single dichotomy method, the single gradient method and the perturbation and observation method from the viewpoint of improved tracking accuracy and speed.

  14. Ergonomics and workplace design: application of Ergo-UAS System in Fiat Group Automobiles.

    Science.gov (United States)

    Vitello, M; Galante, L G; Capoccia, M; Caragnano, G

    2012-01-01

    Since 2008 Fiat Group Automobiles has introduced Ergo-UAS system for the balancing of production lines and to detect ergonomic issues. Ergo-UAS system integrates 2 specific methods: MTM-UAS for time measurement and EAWS as ergonomic method to evaluate biomechanical effort for each workstation. Fiat is using a software system to manage time evaluation and ergo characterization of production cycle (UAS) to perform line balancing and obtain allowance factor in all Italian car manufacturing plant. For new car models, starting from New Panda, FGA is applying Ergo-UAS for workplace design since the earliest phase of product development. This means that workplace design is based on information about new product, new layout, new work organization and is performed by a multidisciplinary team (Work Place Integration Team), focusing on several aspects of product and process: safety, quality and productivity. This allows to find and solve ergonomic threats before the start of production, by means of a strict cooperation between product development, engineering and design, manufacturing. Three examples of workstation design are presented in which application of Ergo-UAS was determinant to find out initial excessive levels of biomechanical load and helped the process designer to improve the workstations and define limits of acceptability. Technical activities (on product or on process), or organizational changes, that have been implemented in order to solve the problems are presented. A comparison between "before" and "new" ergonomic scores necessary to bring workstations in acceptable conditions were made. PMID:22317404

    1996-10-27

    This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

  16. Influence of particulate trap oxidizers on emission of mutagenic compounds by diesel automobiles.

    Rasmussen, R E; Devillez, G; Smith, L R

    1989-06-01

    Diesel exhaust particles are known to contain mutagenic and carcinogenic chemicals. The aim of this study was to determine whether, and to what extent, catalytic particulate trap oxidizers on light-duty diesel engines may reduce the emission of particle-associated mutagenic chemicals into the environment. Exhaust particles were collected from Mercedes Benz and Volkswagen diesel automobiles, equipped with or without the manufacturer's exhaust traps, while running on a chassis dynamometer under specified load conditions. Exhaust particles were collected from a dilution tunnel onto 20" X 20" Teflon-coated fiberglass filters. Mutagenesis tests of dichloromethane (DCM) extracts of the particles were conducted using the Ames Salmonella bacterial test system. The mutation rate was calculated in terms of histidine revertants per mile of travel during a set of standard test cycles. With both vehicles the traps produced an 87-92% reduction in the total amount of particulate material collected by the filters. There was no significant change in the specific mutagenic activity (revertants per microgram of DCM particle extract) with or without the traps. These studies support the notion that installation of exhaust traps which reduce particulate emission on diesel-powered vehicles will also reduce the emission of particle-associated mutagenic and carcinogenic materials into the environment.

    The use of aluminium alloys in the automotive industry has the weight saving attractiveness leading to improved engine efficiency and reduced vibration. The main restriction for the use of highly alloyed aluminium-silicon alloys is the casting difficulty. The spray forming technique allows the production of preforms of uniform microstructure, fine grains and low segregation effects. There are feasible commercial markets for spray formed Al-Si alloy for pistons, con-rod and cylinder liners. The use of these alloys in the automotive industry means that their corrosion performance in fuel environments needs to be evaluated. Lately, the interest in alcoholic fuels has been increasing due to pollutant emission restrictions. In this investigation, the corrosion behaviour of two Al-Si-Cu alloys produced by spray forming has been studied by means of weight loss measurements, electrochemical impedance measurements and potentiodynamic polarisation tests. The tests were carried out in ethanol automobile fuel. The corrosion of a grey cast iron has also been investigated, in the same solution for comparison reasons. (orig.)

    2005-11-01

    The automobile manufacturing industry plays a very important role in a country's economy. The importance of automobile manufacturing industry lies in its sheer size and complexity in terms of the direct and indirect influence it commands across many other industries. While millions of people are employed in the automobile manufacturing industry, it is estimated that more than two and half times that number are employed in the auxiliary companies that supply parts to the automobile manufacturing companies. The auxiliary companies represent a group of businesses of various sizes, types, and geographical locations, producing a vast variety of products ranging from the very simple to the extremely intricate. In this study, the current environmental practices of management in the core Spanish auxiliary companies that do business with the automobile manufacturing industry (and thus form a large part of the automobile manufacturing industry's supply chain) are investigated. We show that while automobile manufacturing companies are under scrutiny to become more and more environmentally friendly, not only at their manufacturing stage but also at their products' useful and EOL stages, there appears to be no such burden on the auxiliary companies. Our conclusion is based on an elaborate survey conducted during the fall of 2004 of Spanish auxiliary companies with questions about the characteristics, environmental practices and reverse logistics related activities carried out by the companies.

    This paper studies how managers at automobile assembly plants organize production across time. Detailed data from eleven single-source automobile assembly plants display considerable cross-plant heterogeneity. At plants which make low- and medium-selling vehicles the capital stock often sits idle, production is more variable than sales, and week-long shutdowns are often used to vary output. In contrast, at plants which make high-selling vehicles, the capital stock rarely sits idle, production...

    A 67 kW (90 hp) Stirling engine design, sized for use in a 1984 1440 kg (3170 lb) automobile was the focal point for developing automotive Stirling engine technology. Since recent trends are towards lighter vehicles, an assessment was made of the applicability of the Stirling technology being developed for smaller, lower power engines. Using both the Philips scaling laws and a Lewis Research Center (Lewis) Stirling engine performance code, dimensional and performance characteristics were determined for a 26 kW (35 hp) and a 37 kW (50 hp) engine for use in a nominal 907 kg (2000 lb) vehicle. Key engine elements were sized and stressed and mechanical layouts were made to ensure mechanical fit and integrity of the engines. Fuel economy estimates indicated that the Stirling engine would maintain a 30 to 45 percent fuel economy advantage comparable spark ignition and diesel powered vehicles in the 1984 period.

    Full Text Available Automobile have become a very important part of our modern life style. But the future of automobile based on internal combustion engines has been badly affected by two major problems. That is less availability of fuel and environmental degradation. So it is very important to found some new renewable non polluting alternative fuels to ensure the proper and safe survival of internal combustion engines. In present study we evaluate the performance of two stroke single cylinder spark ignition engine with ratio of 10% 20% and 30% of ethanol and gasoline by volume. Performance parameters (brake thermal efficiency, brake specific energy consumption and brake specific fuel consumption were determined at various loads on engine with ethanol blended gasoline. The comparison was made on performance of conventional SI engine with pure gasoline operation. As a result, brake thermal efficiency, brake specific fuel consumption and brake specific fuel consumption showed comparable performance when compared with pure gasoline performances.

    Full Text Available In this paper the authors identify and investigate the key factors which influence intentions to purchase passenger cars among consumers in Pakistan. A questionnaire was developed to check the significance of these key variables identified from previous studies, especially those conducted in the context of automobile purchasing in Asian countries. Faculty members from universities of two major cities in Pakistan were selected at random as respondents for this study. The findings of the study will be useful to both managers in the auto industry as well as policy makers. It will help managers in the auto industry to gain a better understanding of consumer intentions and identify the factors which influence them. Policy makers in Pakistan’s auto sector would benefit from the insights of this study when developing the long overdue Auto Policy. Analysis of the data collected has revealed that the three key factors identified from studies in other Asian countries are also relevant for Pakistani auto consumers.

  20. Study of lead pollution from automobile emissions in Khartoum

    International Nuclear Information System (INIS)

    Aerosol and soil samples were collected from places near the main roads in Khartoum area. The samples were analyzed by energy Dispersive x-ray fluorescence (EDXRF) technique, to study the lead (Pb) concentration in air and soil near roadsides due to automobile emissions. The aim of the study was also to make a comparison with the results of previous measurements made in the same field (Ahmed, 1983) . Thee aerosol samples were taken from three sites in Khartoum area. Tuti island taken as a control area, central Khartoum as a commercial area and south of Khartoum as a residential area. Soil samples were taken from a place near Al Gurashi Park and another near Abu Hamama traffic junction in Khartoum area. The data obtained of (Pb) concentrations in the roadside air were statistically analyzed. Comparisons were made between the concentrations at the various times of the day and correlation were made with meteorological parameters. The (Pb) concentrations in the roadside soil were observed to be inversely proportional to the distance from the road and the depth from the layer of the earth. Finally, the results obtained are discussed and some recommendations are suggested. (Author)

    2016-03-01

    Automated automobiles will be on our roads within the next decade but the role of the driver has not yet been formerly recognised or designed. Rather, the driver is often left in a passive monitoring role until they are required to reclaim control from the vehicle. This research aimed to test the idea of driver-initiated automation, in which the automation offers decision support that can be either accepted or ignored. The test case examined a combination of lateral and longitudinal control in addition to an auto-overtake system. Despite putting the driver in control of the automated systems by enabling them to accept or ignore behavioural suggestions (e.g. overtake), there were still issues associated with increased workload and decreased trust. These issues are likely to have arisen due to the way in which the automated system has been designed. Recommendations for improvements in systems design have been made which are likely to improve trust and make the role of the driver more transparent concerning their authority over the automated system.

  2. On the baseline evolution of automobile fuel economy in Europe

    International Nuclear Information System (INIS)

    'Business as usual' scenarios in long-term energy forecasts are crucial for scenario-based policy analyses. This article focuses on fuel economy of passenger cars and light trucks, a long-disputed issue with serious implications for worldwide energy use and CO2 emissions. The current status in Europe is explained and future developments are analysed with the aid of historical data of the last three decades from the United States and Europe. As a result of this analysis, fuel economy values are proposed for use as assumptions in baseline energy/transport scenarios in the 15 'old' European Union Member States. Proposed values are given for new gasoline and diesel cars and for the years 2010, 2020 and 2030. The increasing discrepancy between vehicle fuel consumption measured under test conditions and that in the real world is also considered. One main conclusion is that the European Commission's voluntary agreement with the automobile industry should not be assumed to fully achieve its target under baseline conditions, nor should it be regarded as a major stimulus for autonomous vehicle efficiency improvements after 2010. A second conclusion is that three very recent studies enjoying authority across the EU tend to be overly optimistic as regards the technical progress for conventional and alternative vehicle propulsion technologies under 'business as usual' conditions

    A study conducted to compare the technological status and the resultant potential vehicle characteristics for hydrogen- and battery-powered automobiles that could be produced from 1985 to 2000 is documented in 3 volumes. The primary objectives of the study were: the assessments of applicable energy storage and propulsion technology for the two basic vehicle types (applied to four-passenger cars); a rigorous comparison of vehicle weight, size, and usefulness versus design range; and an investigation of the relative efficiencies of expending energy from various primary sources to power the subject vehicle. Another important objective, unique to hydrogen powered vehicles, was the assessment of the technology, logistics, and cost implications of a hydrogen production and delivery capability. This volume, Volume III, contains three major sections: the assessment of battery electric vehicle technology for energy storage and the drivetrain system; the technical and economic comparison of hydrogen- and battery-powered vehicles derived primarily from data in the previous vehicle technology assessments, with consideration of alternative energy sources; and a series of appendices that support the vehicle definitions and comparisons.

    This lecture introduces a concept of measurement technology with video integration for commercial vehicles. We would like to present DAVIS-CAR, a system for mobile data acquisition. It enables the simultaneous evaluation of video data and test data and consists of mobile as well as of stationary components in a client/server architecture. The product DAVIS-CAR is suitable not only for testing entire vehicles but for external suppliers developing vehicle components or for analysing a person's driving performance. Even for completely stationary systems DAVIS-CAR provides advantages in situations when video data are recorded to get additional information on tests. The mobile server collects the data of the driving car. The storage of these data can be triggered either manually or by events derived from signal states. The stationary system is capable of administering the measurement data and the associated Meta information from several mobile systems at the same time and of providing this information to the connected clients. The ASAM-ODS interface facilitates the integration of DAVIS-CAR in environments typically found in the automobile industry. The overall architecture also enables the integration of data provided by other measurement systems. (orig.)

  6. Death and injury from automobile collisions: an overlooked epidemic.

    2011-05-01

    Automobile collisions are a major source of injury, death, and disability worldwide. Roadway injuries are affected by societal and cultural influences as much as any other health-related event, but have historically received relatively little attention from the medical anthropology community. The development of safety intervention strategies is affected by notions of responsibility for preventive care, including a balance between regulation, technology, and personal choice. This balance may be affected by perceptions of the risks associated with roadway use, potentially related to notions of individual control and the portrayal of collisions in the popular media and lexicon. Prevention efforts are also affected by the definition of injury as a disease-a biological phenomenon requiring research and intervention efforts from the medical and public health communities. Injury prevention priorities and strategies also differ across cultures and locales, dependent in part on economic constraints, native mobility practices, and the quality and expediency of post-trauma care. Progressing injury prevention worldwide requires multidisciplinary action, including an examination of these various cultural and societal influences. We believe that future efforts will benefit from the expertise and analysis of the medical anthropology community. PMID:21590580

    High solid coating is one of the most important environmental friendly coatings, and has been obtained great attention since 70s' last century. For there are high volatile organic compounds(VOCs) in the conventional coatings, which cause both a serious pollution and consume of a plentiful of natural resource, such as petroleum. The development and production of high solid coatings is pressing target for all the countries, especially for China due to our heavy population and short of resources. Based on the requirement, a novel coating with high solid content has been developed in our lab. The solid content of the resin is 80%, compared to the 55% of conversional resin. This coating is characterized by its unique molecular architecture, it is a kind of hyper-branched polymer with uniform distribution of the reactive groups along the molecular backbone, which can react with other chemicals to form a cross-linking structure at high temperature.The coating has a lower viscosity and lower Tg corresponding to its branched structure( scheme 1).This coating has been applied in the automobile finishing. The experimental results indicated that the developed coating presented high performance properties in fastness, mar resistance, and hardness, it also reduced the baking temperature, resulting in a energy saving.

  8. Comparative Frictional Analysis of Automobile Drum and Disc Brakes

    2016-03-01

    Full Text Available In the present work, a comparative frictional behaviour of drum brakes and disc brakes in automobiles has been investigated. The influential factors; contact force and friction radius were modeled for the estimation of the friction coefficient for drum as well as disc brakes. The effect of contact force and friction radius is studied with varying conditions of parameters; longitudinal force, caliper force and torque on piston side as well as non-piston side. The numerical results obtained have been compared with the similar obtained from virtual Matlab/Simulink models for drum and disc brakes. The results evidenced that friction radius predominantly affects brake pressure and thus the friction coefficient, also the increase in contact force resulted with decrease in friction coefficient both for drum and disc brakes. Further it has been found that disc brakes exhibit gradual decrease of friction coefficient due to the equitable distribution of braking effort while drum brake presents sudden variations in friction coefficient. It can be revealed that frictional behaviour of disc brake is more consistent than drum brake.

  14. Cars gone wild: the major contributor to unintended acceleration in automobiles is pedal error

    Directory of Open Access Journals (Sweden)

    Richard A.Schmidt

    2010-11-01

    Full Text Available “Unintended-acceleration” automobile accidents typically begin when the driver first enters the car, starts the engine, and intends to press his/her right foot on the brake while shifting from Park to a drive gear (Drive or Reverse. The driver reports an unintended (uncommanded full-throttle acceleration, coupled with a loss of braking, until the episode ends in a crash. Pedal misapplications--where the right foot contacts the accelerator instead of the brake that was intended--have been linked to these accidents (Schmidt, 1989, 1993 which, in the 1980s, were thought to occur only at the start of a driving cycle (and/or with the car in Park. But, in 1997, we identified over 200 pedal errors as the cause of accidents reported in the North Carolina database; these crashes occurred during the driving cycle (Schmidt et al., 1997, and/or with the vehicle in a gear other than Park. Our present work provides a more thorough analysis of these North Carolina Police Accident Reports from 1979 to 1995. The vast majority of pedal misapplications (over 92% (a occurred during the driving cycle, (b were generally in “unhurried” conditions, and (c were categorically separate from those events referred to as unintended-acceleration episodes at start-up. These ideas are explanatory for the recent (2009-2010 surge of unintended-acceleration reports, perhaps even suggesting that all of these crashes are caused by pedal errors, and that none of them are based on some vehicle defect(s.

    A complex system is composed of many interacting elements, and its behavior, as a whole, can be quite different from that of the individual elements. An automobile is an example of a common mechanical system composed of a large number of individual elements. These elements are connected through soft and hard linkages that transmit motion to each other. This paper proposes a variety of analytical tools to study experimental data from complex systems using two elements of an automobile as an example. Accelerometer measurements were taken from two elements within an automobile: the door and the dashboard. Two types of data were collected: response to impact loading, and response to road excitation of the automobile driven at different speeds. The signals were processed via Fourier and wavelet transforms, cross-correlation coefficients, Hilbert transform, and Kuramoto order parameters. A new parameter, called the order-deficit parameter, is introduced. Considerable, but not complete, synchronization can be found between the accelerations measured at these two locations in the automobile, and the degree of synchronization is quantified using the order-deficit parameter.

    Environmental sustainability and green environmental issues have an increasing popularity among researchers and supply chain practitioners. An attempt has been made to identify and empirically analyze green supply chain management (GSCM) practices in Indian automobile industry. Six main GSCM practices (having 37 sub practices) and four expected performance outcomes (having 16 performances) have been identified by implementing GSCM practices from literature review. Questionnaire based survey has been made to validate these practices and performance outcomes. 123 complete questionnaires were collected from Indian automobile organizations and used for empirical analysis of GSCM practices in Indian automobile industry. Descriptive statistics have been used to know current implementation status of GSCM practices in Indian automobile industry and multiple regression analysis has been carried out to know the impact on expected organizational performance outcomes by current GSCM practices adopted by Indian automobile industry. The results of study suggested that environmental, economic, social and operational performances improve with the implementation of GSCM practices. This paper may play an important role to understand various GSCM implementation issues and help practicing managers to improve their performances in the supply chain.

    International Nuclear Information System (INIS)

    We report on the ion-exchange separation of Pt and Pd from the main elements emitted from catalysts of gasoline-fueled cars by exploiting the selective chelating ion exchanger Lewatit MonoPlus TP-214. Pt and Pd were then eluted with a recovery of 92% and 96%, respectively, using an acidified solution of thiourea, and the eluent was analyzed by sequential voltammetry. The detection limits are 0. 04 μg L-1 and 1 μg L-1 for Pt and Pd, respectively, and the relative standard deviation is about 4. 0% (for n = 10). The procedure was successfully applied to particles emitted from automobile exhaust catalysts of four capacity engine vehicles. Graphite furnace atomic absorption spectrometry was also employed for reasons of comparison. Emission by four vehicles with 1400, 2600, 3200, and 4800 cc engines, respectively, ranged from 19 to 28 ng km-1 for Pt, and from 102 to 150 ng km-1 for Pd. (author)

    The microstructure, mechanical properties, and misorientation of automobile beam steels produced by EAF-CSP process were studied using optical microscopy (OM) and electron back-scattered diffraction (EBSD). It is shown that the microstructure of strips is mainly polygonal ferrite, and the average grain size is about 5-8 μm. The electron back-scattered diffraction results show that grain boundaries in ferrite are basically high-angle grain boundaries without remarkable preferred orientation. Hot strips of automobile beam steels possess a good combination of strength and plasticity because of their fine microstructures and low quantity of impurities.

  17. Bank Angle of a V-Type 12-Cylinder Engine

    Science.gov (United States)

    Ito, Norio; Nakagawa, Akihito; Kitamura, Ryuji

    As the automobile engine advances towards higher performance and higher power, the increase in displacement and the number of cylinders in the engine has led to larger engines. As a result, the need for rigidity countermeasures and reductions in size and weight have brought about the switch from in-line type engines to V-type engines. Currently, most of the V-type automobile engines produced have six or eight cylinders, and some large passenger cars produced in Europe and America have V-type engines with 10 or 12 cylinders. The bank angles of engines in these passenger are almost fixed based on the cylinder number. Therefore, the form of the V-type engine is limited according to the number of cylinders. The present study examines the bank angle of a V-12 engine by performing a detailed analysis of the relationship between the cylinder arrangement and the exciting moment. The goal of the present study is to find a bank angle that has as of yet not been applied to the V-type engine so that the layouts of the absorption and exhaust systems, as well as the attached apparatuses, can be reconfigured.

  20. Contribution of Road Grade to the Energy Use of Modern Automobiles Across Large Datasets of Real-World Drive Cycles: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Wood, E.; Burton, E.; Duran, A.; Gonder, J.

    2014-01-01

    Understanding the real-world power demand of modern automobiles is of critical importance to engineers using modeling and simulation to inform the intelligent design of increasingly efficient powertrains. Increased use of global positioning system (GPS) devices has made large scale data collection of vehicle speed (and associated power demand) a reality. While the availability of real-world GPS data has improved the industry's understanding of in-use vehicle power demand, relatively little attention has been paid to the incremental power requirements imposed by road grade. This analysis quantifies the incremental efficiency impacts of real-world road grade by appending high fidelity elevation profiles to GPS speed traces and performing a large simulation study. Employing a large real-world dataset from the National Renewable Energy Laboratory's Transportation Secure Data Center, vehicle powertrain simulations are performed with and without road grade under five vehicle models. Aggregate results of this study suggest that road grade could be responsible for 1% to 3% of fuel use in light-duty automobiles.

    2013-06-01

    Full Text Available Engine is the main power source of Automobiles , where combustion takes place & produces heat which converts into mechanical energy. We know IC-Engines are used in Automobiles, Aeroplane etc .But the incomplete combustion produces some harmful gasses, which is one main cause of air pollution. Modern Science & Technology has been taken many positive steps for emission control. Like, using CNGs & LPGs instead of petrol & diesel. Nowtechnology brings Electrical bikes, scooters & cars. The battery of electrical vehicle can charge easily like mobile. They have less running cost & 100% emission free. But they have very less load carrying capacity & not suitable for long run. So basically we have to prefer Engines for more power & more running capacity. Here I have introduced a mechanism which has more load caring & running capacity then electrical vehicles but makes zero emission or pollution.

    2015-01-01

    Full Text Available The cooling system of an Automobile plays an important role in its performance, consists of two main parts, known as radiator and fan. Improving thermal efficiency of engine leads to increase the engine's performance, decline the fuel consumption and decrease the pollution emissions. Water and ethylene glycol as conventional coolants have been widely used in radiators of an automotive industry for many years. These heat transfer fluids offer low thermal conductivity. With the advancement of nanotechnology, the new generation of heat transfer fluids called, “nanofluids” have been developed and researchers found that these fluids offer higher thermal conductivity compared to that of conventional coolants. This study focused on the preparation of Zinc based nanofluids (ZnFe2O4 using chemical co-precipitation method and its application in an automotive cooling system along with mixture of ethylene glycol and water (50:50. Relevant input data, nanofluids properties and empirical correlations were obtained from literatures to investigate the heat transfer enhancement of an automotive car radiator operated with nano fluid-based coolants. It was observed that, overall heat transfer coefficient and heat transfer rate in engine cooling system increased with the usage of nanofluids (with ethylene glycol the base-fluid compared to ethylene glycol (i.e. base-fluid alone. It is observed that, about 78% of heat transfer enhancement could be achieved with the addition of 1% ZnFe2O4 particles in a base fluid at the Reynolds number of 84.4x103 and 39.5x103 for air and coolant respectively

    Full Text Available This paper endeavors to present a classification, review and analysis of the literature on Plant Maintenance Management Practices (PMMP employed in Automobile Industries. There is a considerable amount of published research available concerning plant maintenance during the last few decades. Similarly many research articles are available which focuses on various aspects of automobile industries. However, very few studies focus on critical examination of maintenance practices in Automobile Industries in particular. Hence considering the slump in automobile industries in the recent times, a wide-ranging and focused review is attempted here and only those researches have been examined which mainly concentrates on this core aspect. Thus one of the objectives of this literature review is to investigate the present state of Plant Maintenance Management Practices, based on studies conducted in different countries and published in a variety of journals over the past two decades. An examination of 55 pertinent research studies have shown that the publications can be grouped in two categories namely Conceptual and Empirical Research. An analysis of these research articles published between 1990 and 2008, revealed that current maintenance practices ranges from conventional to the latest techniques for optimizing maintenance function like TPM, RCM and Proactive Maintenance. These studies focused more on maintenance problem solving and the main difficulties are reported along with probable solutions. Another goal of the paper is to analyze the articles by year and type of journal they were published in, to determine the trends in maintenance management studies and recommend future direction for research.

    1979-03-01

    This report projects to the year 2025 the total number of automobiles that would be owned by American households, (total ownership) and the total number of miles that these vehicles would be driven per day (total use) given certain assumptions about the future of U.S. society. These assumptions relate to demographic, economic, and geographical attrributes of U.S. society that are relevant to the automobile. The impacts of these assumptions were analyzed via a set of projection models which explicitly recognize the relationship between these particular attributes of society and the automobile. Part I presents an overivew of the research and Part II the results. The methodology used to generate the projections is discussed in some detail in Part III. In a base case projection the number of automobiles and average daily travel of Americans double by 2025 due to increases in populaion, headship rates (households per population), and incomes. economic variables account for about half of this increase as indicated by a no economic growth projection in which ownership and daily travel increase just over 40% and 50%, respectively. Other projections explore the effects of differing assumptions regarding rates of household formations, population growth, and income growth. Model projections suggest that changed work schedules and the re-emergence of cities as growth areas will have only slight impacts on future travel and vehicle ownership.

    Full Text Available The aim of the paper is to present a three dimensional transient cooling analysis of an automobile cabin with a virtual manikin under solar radiation. In the numerical simulations the velocity and the temperature distributions in the automobile cabin as well as around the human body surfaces were computed during transient cooling period. The surface-to-surface radiation model was used for calculations of radiation heat transfer between the interior surfaces of the automobile cabin and a solar load model that can be used to calculate radiation effects from the sun's rays that enter from the glazing surfaces of the cabin was used for solar radiation effects. Inhomogeneous air flow and non-uniform temperature distributions were obtained in the automobile cabin and, especially in ten minutes of cooling period, high temperature gradients were computed and measured and high temperature values were obtained for the surfaces which were more affected from the sunlight. Validations of the numerical results were performed by comparing numerical data with the experimental data presented in this study. It is shown that the numerical results were good agreement with the experimental data.

    Modern cars use more and more electric power due to more on-board electric systems, e.g., ABS brakes, active suspension systems, electric windows, chair adjustment systems and electronic engine control systems. One possible energy source for electricity generation is to use the waste heat from the car`s engine, which generally is as much as 80% of the total energy from the combustion of the gasoline. Maybe the best location to tap the excess heat is the Catalytic Converter (Cat) in the exhaust system or perhaps at the exhaust pipes close to the engine. The Cat must be kept within a certain temperature interval. Large amounts of heat are dissipated through the wall of the Cat. A Thermionic Energy Converter (TEC) in coaxial form could conveniently be located around the ceramic cartridge of the Cat. Since the TEC is a rather good heat insulator before it reaches its working temperature the Cat will reach working temperature faster, and the final temperature of it can be controlled better when encapsulated in a concentric TEC arrangement. It is also possible to regulate the temperature of the Cat and the TEC by controlling the electrical load of the TEC. The possible working temperatures of present and future Cats appear very suitable for the new low work function collector TEC, which has been demonstrated to work down to 470 K.

    The present work focuses the application of nanostructured materials for storing of hydrogen in different carbon materials by physisorption method. To market a hydrogen-fuel cell vehicle as competitively as the present internal combustion engine vehicles, there is a need for materials that can store a minimum of 6.5wt% of hydrogen. Carbon materials are being heavily investigated because of their promise to offer an economical solution to the challenge of safe storage of large hydrogen quantities. Hydrogen is important as a new source of energy for automotive applications. It is clear that the key challenge in developing this technology is hydrogen storage. Combustion of fossil fuels and their overuse is at present a serious concern as it is creates severe air pollution and global environmental problems; like global warming, acid rains, ozone depletion in stratosphere etc. This necessitated the search for possible alternative sources of energy. Though there are a number of primary energy sources available, such as thermonuclear energy, solar energy, wind energy, hydropower, geothermal energy etc, in contrast to the fossil fuels in most cases, these new primary energy sources cannot be used directly and thus they must be converted into fuels, that is to say, a new energy carrier is needed. Hydrogen fuel cells are two to three times more efficient than combustion engines. As they become more widely available, they will reduce dependence on fossil fuels. In a fuel cell, hydrogen and oxygen are combined in an electrochemical reaction that produces electricity and, as a byproduct, water.

  9. Materials used in automobile manufacture - current state and perspectives

    International Nuclear Information System (INIS)

    The materials which are applied in modern motor vehicles can be considered to be optimally accommodated to the actual demands. Normally a change of materials is only required if by that a cost reduction can be realized, or if the demands change. Such changes at present or in the near future mainly concern ecological aspects: consumption reduction; weight reduction; low emission of pollutants by vehicles and in the production process; recycling of materials. Those materials in question which better accommodate the new requirements can be: improved variants of actually applied materials; fully developed materials approved already in other technical areas but not yet applied in automotive engineering; newly developed materials. Starting from the actual conception examples will be given for each category. They will show that the cost of future materials tend to be higher, but that even with more expensive materials sometimes the cost of a component can be reduced. (orig.)

    The placement of thermoelectric generators (TEGs) in vehicles is analyzed, taking into account the interaction of the TEG with the internal combustion engine (ICE). Alternative locations of the TEG directly in the ICE, on the exhaust pipe, and on the cooling system are considered. In all three cases there is a conflict between the two thermal machines, which reduces the total efficiency of the thermodynamic (ICE + TEG) system. It is shown that the cause of the conflict is the low efficiency of the TEG ( η TEG cars by the TEG, are significantly limited. Also, some problems of finding materials for automotive TEGs and ways to suppress the parasitic Thomson effect in TEG legs are discussed.

  11. Diesel engines vs. spark ignition gasoline engines -- Which is ``greener``?

    Energy Technology Data Exchange (ETDEWEB)

    Fairbanks, J.W. [Dept. of Energy, Washington, DC (United States)

    1997-12-31

    Criteria emissions, i.e., NO{sub x}, PM, CO, CO{sub 2}, and H{sub 2}, from recently manufactured automobiles, compared on the basis of what actually comes out of the engines, the diesel engine is greener than spark ignition gasoline engines and this advantage for the diesel engine increases with time. SI gasoline engines tend to get out of tune more than diesel engines and 3-way catalytic converters and oxygen sensors degrade with use. Highway measurements of NO{sub 2}, H{sub 2}, and CO revealed that for each model year, 10% of the vehicles produce 50% of the emissions and older model years emit more than recent model year vehicles. Since 1974, cars with SI gasoline engines have uncontrolled emission until the 3-way catalytic converter reaches operating temperature, which occurs after roughly 7 miles of driving. Honda reports a system to be introduced in 1998 that will alleviate this cold start problem by storing the emissions then sending them through the catalytic converter after it reaches operating temperature. Acceleration enrichment, wherein considerable excess fuel is introduced to keep temperatures down of SI gasoline engine in-cylinder components and catalytic converters so these parts meet warranty, results in 2,500 times more CO and 40 times more H{sub 2} being emitted. One cannot kill oneself, accidentally or otherwise, with CO from a diesel engine vehicle in a confined space. There are 2,850 deaths per year attributable to CO from SI gasoline engine cars. Diesel fuel has advantages compared with gasoline. Refinery emissions are lower as catalytic cracking isn`t necessary. The low volatility of diesel fuel results in a much lower probability of fires. Emissions could be improved by further reducing sulfur and aromatics and/or fuel additives. Reformulated fuel has become the term covering reducing the fuels contribution to emissions. Further PM reduction should be anticipated with reformulated diesel and gasoline fuels.

    The article proposes an expert system for detection, and subsequent investigation, of groups of collaborating automobile insurance fraudsters. The system is described and examined in great detail, several technical difficulties in detecting fraud are also considered, for it to be applicable in practice. Opposed to many other approaches, the system uses networks for representation of data. Networks are the most natural representation of such a relational domain, allowing formulation and analysis of complex relations between entities. Fraudulent entities are found by employing a novel assessment algorithm, \\textit{Iterative Assessment Algorithm} (\\textit{IAA}), also presented in the article. Besides intrinsic attributes of entities, the algorithm explores also the relations between entities. The prototype was evaluated and rigorously analyzed on real world data. Results show that automobile insurance fraud can be efficiently detected with the proposed system and that appropriate data representation is vital.

    The catalytic purification of automobile exhaust gases (CO, NOx and hydrocarbons) is one of the most practiced conversion processes used to lower the emissions and to reduce the air pollution. Nevertheless, the good performance of exhaust gas purification catalysts often requires the high consumption of noble metals such as platinum. Here we report that the Brønsted acid sites on the external surface of a microporous silicoaluminophosphate (SAPO) act as a promoter for exhaust gas purification...

  1. Estimating the Price Overcharge from Cartelisation of the Irish Automobile Industry

    Price coordination can be very harmful for consumers. Yet, even if a cartel is proved to exist, and successful in enforcement, how do we estimate damages or price overcharges to consumers? We build a structural model of the Irish automobile market that avails of a crosssection of new cars and jointly estimate demand and cost primitives. We use these estimates to quantify the role that price coordination could play in terms of pricing, profits and burden of taxation in three alternative regime...

    1991-03-01

    To evaluate the role of neurobehavioural factors in the aetiology of recurrent automobile accidents, we administered the Revised Wechsler Adult Intelligence Scale (WAIS-R), the Eysenck Personality Questionnaire (EPQ), and choice and simple reaction time tests to 31 accident-prone automobile drivers. These drivers who had caused three or more traffic accidents during the years 1980-1984, were selected from records of 2723 traffic accidents registered by Hefei Traffic Police Department during the years 1980-1984. The same tests were administered to an equal number of sex- and age-matched control drivers who had no reported involvement in automobile accidents. None of the subjects had suffered from any neuropsychiatric illness or head injury. Comparisons between the two groups indicated that for accident-prone drivers scores on picture completion and block design subtests of the WAIS-R were significantly lowered (p less than 0.05); scores for neurosis extrovert behaviour and psychosis (EPQ) were significantly higher (p less than 0.05); and the number of errors in the choice reaction time test was significantly higher (p less than 0.01). It is suggested that accident-prone drivers have lower psychological performance, poorer judgement and a higher tendency than safe drivers to be neurotic, extrovert and psychotic. PMID:2066226

    Aiming at developing exhaust gas driving automobile air conditioning systems, a hydride pair LaNi4.61Mn0.26A10.13/La0.6Y0.4Ni4.8Mn0.2 was developed working at 393~473 K/293~323 K/263~273 K. Property tests showed that both alloys have flat plateau slopes and small hystereses; system theoretical coefficient of performance (COP) is 0.711. Based on this work pair, a function proving automobile metal hydride refrigeration system was constructed. The equivalent thermal conductivities of the activated reaction beds were merely 1.1~1.6 W/(m·K), which had not met practical requirement. Intermittent refrigeration cycles were achieved and the average cooling power was 84.6 W at 423 K/303 K/273 K with COP being 0.26. By altering cycling parameters, experiment data showed that cooling power and system COP increase with the growth of heat source temperature as well as pre-heating and regeneration time while decrease with heat sink temperature increment. This study confirms the feasibility of automobile metal hydride refrigeration systems, while heat transfer properties of reaction beds still need to be improved for better performance.

  9. Kinetic considerations of three-way catalysis in automobile exhaust converters

    International Nuclear Information System (INIS)

    The activity of three-way catalysts is highly dependent on the reactants present in the automobile exhaust gases (CO, NOx, HC, O2, H2O, CO2, N2) as well as their relative concentration. Thus, the influence of each reactant on the kinetic behavior of the whole mixture makes difficult to establish the accurate kinetics of the system. Activity experiments carried out close to the real operation conditions (GHSV, concentration, etc.) with a Pt/CeO2/Al2O3 catalyst supplied data on the CO and HC oxidation and NO reduction reactions in environments formed by different reactant combinations (from binary mixtures to the whole mixture simulating the real conditions at the automobile converter).The obtained results have shown notable variations in the oxidation/reduction mechanisms depending on the presence (or absence) of components in the environment. The presence of water always promoted the three-way activity of the catalyst. The compensation effect applied to the CO, NO and HC conversions confirmed that kinetic expressions obtained with partial mixtures (not very close to the real converter environment) have only limited application for determining the whole kinetic scheme occurring in the automobile converters

    The implementation possibilities of future drive concepts - from hybrid systems comprising an electric motor and an internal combustion engine to fuel cells to alternative fuels like hydrogen or alcohol - will depend largely on quality criteria, e.g. power density, rotary momentum, acceleration characteristics, specific energy consumption, emissions of chemical substances, and noise. The boundary criteria for the introduction of realizeable concepts of alternative drives for motor cars will be defined by the availability and storability of the envisaged fuels, technical complexity, cost, safety, infrastructure and service. The book presents and analyzes the processes, drives and energy sources that can be combined in complex energy management systems for motor cars in accordance with the aforementioned criteria. Knowledge about these facts is indispensable for the development of new concepts. The 2nd edition describes many new developments in car propulsion systems as well as their combinations, new energy sources, energy converters and energy stores.

    2001-10-01

    It is possible to operate a heat engine using a cold substance, such as liquid nitrogen, as a heat sink and the atmosphere as a heat source.(C. A. Ordonez, American Journal of Physics 64), (1996) 479-481. With sufficient work produced per unit mass of liquid nitrogen, such a cryogenic heat engine may be suitable for powering short range, non-polluting automobiles.(C. A. Ordonez, Energy Conversion and Management 41) (2000) 331-341. Using existing liquid nitrogen plants to produce liquid nitrogen at about 50% of Carnot efficiency, and using renewable energy to power the liquid nitrogen plants, the cost to use liquid nitrogen to power an automobile per mile driven would be a few times the cost of using gasoline in the U.S. The increased ``fuel" cost may be acceptable for short range vehicles provided such vehicles have an acceptable price. We report on thermal-to-electrical energy conversion systems being studied for use as cryogenic heat engines. Specifically, capacitors made using paraelectric materials can provide energy conversion based on the electrocaloric effect. The electrocaloric effect is a change in electric field across a material that results from a change in temperature of the material.

    2014-10-01

    Full Text Available Measurement of real driving emissions (RDE from internal combustion engines under real-world operation using portable, onboard monitoring systems (PEMS is becoming an increasingly important tool aiding the assessment of the effects of new fuels and technologies on environment and human health. The knowledge of exhaust flow is one of the prerequisites for successful RDE measurement with PEMS. One of the simplest approaches for estimating the exhaust flow from virtually any engine is its computation from the intake air flow, which is calculated from measured engine rpm and intake manifold charge pressure and temperature using a generic speed-density algorithm, applicable to most contemporary four-cycle engines. In this work, a generic speed-density algorithm was compared against several reference methods on representative European production engines - a gasoline port-injected automobile engine, two turbocharged diesel automobile engines, and a heavy-duty turbocharged diesel engine. The overall results suggest that the uncertainty of the generic speed-density method is on the order of 10% throughout most of the engine operating range, but increasing to tens of percent where high-volume exhaust gas recirculation is used. For non-EGR engines, such uncertainty is acceptable for many simpler and screening measurements, and may be, where desired, reduced by engine-specific calibration.

    Full Text Available With the increase of human population there has been an evident increase in per capita automobile use and ownership, significantly to a point that almost every urban university campus faces serious challenges from the heavy traffic movement as well as the associated parking shortages. Multiple factors, including lack of land for new parking lots, high cost of building parking structures and the desire to preserve the air quality and campus green spaces are leading many educational institutions towards a new vision based upon expanded transit access, better bicycle and pedestrian facilities and financial incentives for students and staff to drive less. (Toor and Havlick, 2004 This is in stark contrast to the traditional approach to campus transportation planning of the University of Malaya (UM, Kuala Lumpur, Malaysia that allows students, staff and visitors to drive in the campus. The objective of this study is to investigate the related issues and environmental impact of allowing automobile driving in the campus. Studies will also be done to analyse the relationship between university campus planning and traffic condition. Air quality and noise pollution data of 3 selected sites in the campus will be recorded. Subsequently, the air pollutant index and noise pollution level will be identified and data analyses will be done on the data samples. Simultaneously, a survey questionnaire will be conducted to gauge the student’s attitude and degree of awareness with air and noise pollution in the campus.

    conservation made necessary by the economic situation. This article examines the compatibility of these two objectives with regard to automobiles. All antiwaste or antipollution efforts not involving the energy generator make up an obvious area of compatibility. On the other hand, the reduction of pollutant emissions requires more or less far-reaching changes in engines, including some that moy create problems from the standpoint of energy conservation. In on attempt to specify the nature of such problems, pollution-control techniques corresponding to different levels of emission limiting are examined from the standpoint of their cost, their influence on fuel consumption and their interaction with energy-conservation processes. A review is thus made of emission-reduction methods based on improving combustion, post-combustion processes, and the problem of reducing the lead content of gasoline.

  5. An impending platinum crisis and its implications for the future of the automobile

    International Nuclear Information System (INIS)

    The global demand for platinum has consistently outgrown supply in the past decade. This trend likely will continue and the imbalance may possibly escalate into a crisis. Platinum plays pivotal roles in both conventional automobile emissions control and the envisioned hydrogen economy. A platinum crisis would have profound implications on energy and environment. On the one hand, inadequate platinum supply will prevent widespread commercialization of hydrogen fuel-cell vehicles. On the other hand, expensive platinum may enhance the competitiveness of hybrid, plug-in hybrid, and battery-powered electric cars. Policymakers should weigh the potential impacts of a platinum crisis in energy policy.

    2006-11-01

    The car, and the range of social and political institutions which sustain its dominance, play an important role in many of the environmental problems faced by contemporary society. But in order to understand the possibilities for moving towards sustainability and 'greening cars', it is first necessary to understand the political forces that have made cars so dominant. This book identifies these forces as a combination of political economy and cultural politics. From the early twentieth century, the car became central to the organization of capitalism and deeply embedded in individual identities, providing people with a source of value and meaning but in a way which was broadly consistent with social imperatives for mobility. Projects for sustainability to reduce the environmental impacts of cars are therefore constrained by these forces but must deal with them in order to shape and achieve their goals. Addresses the increasingly controversial debate on the place of the car in contemporary society and its contribution to environmental problems Questions whether automobility is sustainable and what political, social and economic forces might prevent this Will appeal to scholars and advanced students from a wide range of disciplines including environmental politics, political economy, environmental studies, cultural studies and geography

  2. First gaseous sulfuric acid measurements in automobile exhaust: Implications for volatile nanoparticle formation

    Science.gov (United States)

    Arnold, F.; Pirjola, L.; Aufmhoff, H.; Schuck, T.; Lähde, T.; Hämeri, K.

    Gaseous sulfuric acid (GSA) is thought to represent an important if not the most important nucleating gas present in modern diesel automobile exhaust. It triggers the formation of new aerosol particles, which grow by condensation and coagulation. Here we report on the first measurements of GSA in automobile exhaust. The experiment was made using a modern passenger diesel car equipped with an exhaust after-treatment system composed of an oxidation catalyst and a diesel-particle filter. The diesel fuel used had an ultra-low sulfur mass fraction of only 5×10 -6. Measured GSA number concentrations reached up to 1×10 9 cm -3. Freshly nucleated particles with diameters larger than 3 nm were also measured. The concentrations reached up to 1×10 5 cm -3 and were positively correlated with GSA for GSA exceeding a threshold value in the range of 5×10 7-2×10 8 cm -3. This suggests that GSA was involved in the formation of new volatile particles.

    Full Text Available So far Most of the current work on this area deals with traffic volume prediction during peak hours and the reasons behind accidents only. This work presents the analysis of automobile vehicle directing in various traffic flow conditions using Artificial neural network architecture. Now a days, due to unprecedented increase in automobile vehicular traffic especially in metro-Politian cities, it has become highly imperative that we must choose an optimum road route in accordance with our requirements. The requirements are : volume of the traffic, Distance between source and destination, no of signals in between the source and destination, the nature of the road condition , fuel consumption and Travel Timing. Artificial Neural networks, a soft computing technique, modeled after brain biological neuron functioning, helps to obtain the required road way or route as per the training given to it. Here we make use of Back propagation network, which changes the weights value of the hidden layers, thereby activation function value which fires the neuron to get the required output.

    1995-05-01

    In this paper, the feasibility of using electronically steerable antennas for health monitoring of civil structures and early warning of collapsing bridges to the approaching vehicles is presented. These antennas can also be used in automobile collision warning systems. These antennas are lightweight, low volume, low profile and conformal. They have low fabrication costs and are easily mass produced. They are thin and do not perturb the aerodynamics of a host automobile. Linear, circular, and dual polarization are achieved with simple changes in feed position. Beam steering is accomplished by varying the relative phase between radiating elements. In planar array, both horizontal and vertical beam can be combined to provide full scanning capabilities. Tunable ceramic phase shifters are used in these antennas. The dielectric properties of the ferroelectric material are changed by a bias voltage. In the case of health monitoring of civil structures, these antennas are used in conjunction with ferroelectric sensors. The sensors are fabricated with interdigital transducers printed on a piezoelectric polymer or ceramic type film. They are in turn mounted onto an ultra thin Penn State's novel RF antenna. The wave form measurements may be monitored at a remote location via the antenna in the sensors and the electronically steerable antenna outlined above.

    In this paper, we present a robot vision based system for coordinate measurement of feature points on large scale automobile parts. Our system consists of an industrial 6-DOF robot mounted with a CCD camera and a PC. The system controls the robot into the area of feature points. The images of measuring feature points are acquired by the camera mounted on the robot. 3D positions of the feature points are obtained from a model based pose estimation that applies to the images. The measured positions of all feature points are then transformed to the reference coordinate of feature points whose positions are obtained from the coordinate measuring machine (CMM). Finally, the point-to-point distances between the measured feature points and the reference feature points are calculated and reported. The results show that the root mean square error (RMSE) of measure values obtained by our system is less than 0.5mm. Our system is adequate for automobile assembly and can perform faster than conventional methods.

    Full Text Available An implicit assumption underlying government strategies to achieve a more sustainable urban transportation system is that all automobile users will be encouraged or persuaded to use more “green” transportation: public transportation, walking and cycling. Little consideration has been given as to how sustainable transportation policies and programmess might impact on different age groups in society, including those retired or semi-retired, despite the fact that an unprecedented number of older drivers will be on the highways in the next few decades. There is limited literature on the contextual factors behind their continued reliance on automobiles, their actual driving behavior (e.g., route choice and time of day to drive framed within the context of social sustainability. This paper introduces the elements of transportation and social sustainability then conducts a comprehensive international literature review focusing on older drivers, their travel choices and associated social sustainability issues. It describes a case study, low-density city and presents empirical evidence, from two surveys conducted in Canberra, Australia. The paper concludes with future research directions that address these issues associated with sustainable transportation.

    Full Text Available The Japanese automobile industry has been hit sharply by the economic downturn of recent decades. The rise in costs and decline in sales have led to serious problems in the auto industry. In order to address these issues, most companies engage in downsizing and redesigning production operations. It is crucial to investigate the time wasted by replacing assembly boards occurring in manufacturing lines. Therefore, the aim of this study was to provide an integrated approach, Teoriya Resheniya Izobreatatelskih Zadatch (TRIZ, to providing efficient solutions for the automobile industry. The first step of this methodology is to detail the technical problems using the Function and Attribute Analysis (FAA model. Secondly, a contradiction matrix and the inventive principle were applied to find the solutions. In this study, an auto part supplier named Sumi-Hanel located in Hanoi, Vietnam, was taken as a case study; the empirical results showed that waste time had been reduced to 67%, nearly 8400 square meters was saved, and a 20% cost reduction was achieved by reusing old frames. The research proves that the combination of TRIZ and lean manufacturing successfully increases production performance and reduces waste due to technological advancements.

    The air quality and thermal comfort strongly influenced by the heat and mass transfer take place together in an automobile cabin. In this study, it is aimed to investigate and assess the effects of air intake settings (recirculation and fresh air) on the thermal comfort, air quality satisfaction and energy usage during the cooling period of an automobile cabin. For this purpose, measurements (temperature, air velocity, CO2) were performed at various locations inside the cabin. Furthermore, whole body and local responses of the human subjects were noted while skin temperatures were measured. A mathematical model was arranged in order to estimate CO2 concentration and energy usage inside the vehicle cabin and verified with experimental data. It is shown that CO2 level inside of the cabin can be greater than the threshold value recommended for the driving safety if two and more occupants exist in the car. It is also shown that an advanced climate control system may satisfy the requirements for the air quality and thermal comfort as well as to reduce the energy usage for the cooling of a vehicle cabin.

  11. Anti-Rolling Suspension for an Automobile by Coupled Electromagnetic Devices

    Science.gov (United States)

    Hayashi, Ryuzo; Suda, Yoshihiro; Nakano, Kimihiko

    Nowadays, various suspension control technologies have been developed such as active suspensions, semi-active suspensions and active stabilizers. As an alternative to a hydraulic actuator for suspension, electromagnetic devices have been developed. Electromagnetic devices are attracting much interest due to their high responsiveness, controllability, energy saving performance, and so on. Besides these advantages, electromagnetic devices can be connected to each other very easily. Therefore, the authors focus on this characteristic of the electromagnetic device and propose two methods to use coupled electromagnetic devices as an anti-rolling control device as well as vertical shock absorbers. The automobile experiences anti-rolling effects, such as roll damping and roll stabilization, without affecting the bouncing motion. Through basic experiments with two motors and control circuits, the performance of the proposed system is examined. The results indicate the coupled electromagnetic devices can be operated as a variable roll damper or a roll stabilizer. Numerical simulations of the turning automobile are carried out, and the results indicate the proposed system is effective.

  12. Influence of catalyst deactivation on N2O emissions from automobiles

    International Nuclear Information System (INIS)

    Though estimates of the total N2O emitted by automobiles differ widely, automobiles are believed to be a significant source of non-agricultural anthropogenic N2O emissions. At the Third Conference of the Parties (COP-3) UN Framework Convention on Climate Change, held in Kyoto in 1997, N2O was designated as a greenhouse gas whose release into the atmosphere must be reduced. This action increased the need for more accurate estimates of automotive N2O emissions. The wide variation in estimates may be attributed to differences in emission test modes, types of catalysts, and levels of catalyst deactivation involved in the tests. In this study, we examined the influence of automotive catalyst deactivation on N2O emissions from the perspective of catalyst temperature frequency distribution. Using a model gas and deactivated three-way catalysts (TWCs), we applied the exhaust emission test modes of various countries. The results indicate that the factor behind the increase of N2O emissions following catalyst deactivation is not growth in N2O generation, but a decline in the N2O decomposition capability of the catalyst. It was also found that the effect of catalyst deactivation differs according to the catalyst composition and the emission test mode.(author)

    2012-04-01

    The aim of the work presented in this paper consists of the development of a decision-making support system, based on discrete-event simulation models, of an automobile assembly line which was implemented within an Arena simulation environment and focused at a very specific class of production lines with a four closed-loop network configuration. This layout system reflects one of the most common configurations of automobile assembly and preassembly lines formed by conveyors. The sum of the number of pallets on the intermediate buffers, remains constant, except for the fourth closed-loop, which depends on the four-door car ratio (x) implemented between the door disassembly and assembly stations of the car body. Some governing equations of the four closed-loops are not compatible with the capacities of several intermediate buffers for certain values of variable x. This incompatibility shows how the assembly line cannot operate in practice for x0,97 in a stationary regime, due to the starvation phenomenon or the failure of supply to the machines on the production line. We have evaluated the impact of the pallet numbers circulating on the first closed-loop on the performance of the production line, translated into the number of cars produced/hour, in order to improve the availability of the entire manufacturing system for any value of x. Until the present date, these facts have not been presented in specialized literature.

  14. Limits to leapfrogging in energy technologies? Evidence from the Chinese automobile industry

    International Nuclear Information System (INIS)

    Limits to leapfrogging in energy technologies? One of the most attractive notions in the field of sustainable energy development is the concept of energy-technology 'leapfrogging'. Leapfrogging through international technology transfer can be especially problematic because often developing countries do not have the technological capabilities to produce or integrate the advanced energy technologies themselves. Until they have acquired the capabilities to produce the advanced technologies themselves, most late-industrializing countries buy their new technologies from industrialized countries, usually through licensing or joint-venture arrangements. Empirical case studies of the three main Sino-US passenger-car joint ventures reveal that until the late 1990s, little energy or environmental leapfrogging occurred in the Chinese automobile industry as the result of the introduction of US automotive technology. An improvement in Chinese capabilities and more stringent Chinese energy and environmental policies are needed to induce energy leapfrogging in the Chinese automobile industry. Foreign firms also have a social responsibility to contribute to China's sustainable industrial development. In order to realize the promise of the leapfrogging, the limits to leapfrogging must be identified and acknowledged so that strategies can be devised to surmount the barriers to the introduction of advanced energy technologies in developing countries

    Three questions relating to the technical progress in the utilization of heavy oils are discussed. The first question considers solid injection in high-speed automobile engines, the second concerns the development of the hot-bulb engine, and the third question relates to the need for a more thorough investigation of the processes on which the formatation of combustible, rapidly-burning mixtures depend.

  19. Investigation of NOx Removal from Small Engine Exhaust

    Contribution of emissions from small engines to the air pollution is significant. Due to differences in operating conditions and economics, the pollution control systems designed for automobiles will be neither suitable nor economically feasible for use on small engines. The objective of this project was to find a catalyst for the removal of NOx from the exhaust of small engines which use a rich air to fuel ratio. The desired catalyst should be inexpensive so that the cost of the pollution control unit will be only a small fraction of the total equipment cost. The high cost of noble metals makes them too expensive for use as NOx catalyst for small engines. Catalytic reduction of Nitrogen Oxide (NO) can also be accomplished by base-metal oxide catalysts. The main disadvantage of base-metal catalysts is their deactivation by poisons and high temperatures. Requirements for the length of the life of the small engine exhaust catalysts are much less than those for automobile exhaust catalysts. Since there is no oxygen in the exhaust gases, reduction selectivity is not a problem. Also, the reducing exhaust gases might help prevent the harmful interactions of the catalyst with the support. For these reasons only the supported metal oxide catalysts were investigated in this project.
