Electric vehicle (EV) has become a potential traffic tool, which has attracted researchers to explore various traffic phenomena caused by EV (e.g. congestion, electricity consumption, etc.). In this paper, we study the energy consumption (including the fuel consumption and the electricity consumption) and emissions of heterogeneous traffic flow (that consists of the traditional vehicle (TV) and EV) under three traffic situations (i.e. uniform flow, shock and rarefaction waves, and a small perturbation) from the perspective of macro traffic flow. The numerical results show that the proportion of electric vehicular flow has great effects on the TV’s fuel consumption and emissions and the EV’s electricity consumption, i.e. the fuel consumption and emissions decrease while the electricity consumption increases with the increase of the proportion of electric vehicular flow. The results can help us better understand the energy consumption and emissions of the heterogeneous traffic flow consisting of TV and EV.

The article was dedicated to the topic of energy consumption of driving cars equipped with an electric motor. Due to the emerging demands for the excessive use of energy by vehicles (including car-sharing system vehicles), the authors carried out research to determine factors that affect the energy consumption. Due to the occurrence of a research gap related to the lack of reliable scientific information regarding real electricity consumption by vehicles used in car-sharing systems, the authors attempted to determine these values based on the proposed research experiment. The purpose of the research was to identify factors that increase energy consumption while driving in the case of car-sharing systems and developing recommendations for users of car-sharing systems and system operators in relation to energy consumption. Based on data received from car-sharing system operators and to their demands that users move cars uneconomically and use too much energy, the authors performed a scientific experiment based on Hartley’s plan. The authors made journeys with electric cars from car-sharing (measurements) in order to compare real consumption with data obtained from operators. As a result, the authors developed a list of factors that negatively affect the energy consumption of electric vehicles from car-sharing systems. As conclusion, a number of recommendations were developed for car-sharing system operators on how to manage their systems to reduce excessive energy consumption in electric vehicles.

RESUMOO Irã como país em desenvolvimento está enfrentando uma quantidade excessiva de poluição do ar em suas grandes cidades. Parece que usar veículos elétricos / híbridos é uma solução apropriada, mas qual carro será mais compatível com a sociedade, o ambiente e as pessoas do Irã ainda é vago? Para responder a essa pergunta, projetamos nosso modelo no qual os quatro híbridos mais populares mundialmente / A eletricidade foi analisada com base nas idéias de especialistas. Em geral, é utilizado o método analítico-descritivo, a comunidade da pesquisa inclui todos os especialistas no campo da gestão ambiental e o tamanho da amostra é obtido usando o método objetivo não aleatório (10 especialistas foram questionados) para priorizar entre carros diferentes com base em um método processo analítico de hierarquia. Os resultados mostraram que, com base na perspectiva dos especialistas, veículos totalmente elétricos são preferencialmente mais compatíveis com a situação do Irã do que veículos híbridos. A característica mais significativa que é contribuída para os veículos elétricos é o alto nível de eficiência de combustível e a menor quantidade de poluição atribuída ao seu motor elétrico, o que significa que eles não liberarão nenhuma poluição no ar. Finalmente, com base nos resultados, sugerimos algumas estratégias, entre as quais a substituição de veículos a combustível antigos e de baixa eficiência, aplicando impostos excessivos regularmente.Palavras-chave: Veículos Elétricos / Híbridos, Poluição do Ar, Transporte Urbano.USING GREEN VEHICLES AS AN APPROACH TO IMPROVE AIR QUALITY IN IRANIAN METROPOLISESNowadays due to the overwhelming levels of pollution, especially in large cities, going green, which means products have higher levels of energy consumption efficiency, is one of the crucial features of any product. In fact being green for vehicles which are responsible for majority of air pollution is significant, therefore companies are trying to product more environment-friendly cars and governments are more intended to place more environmental standards on this industry. Iran as a developing country is facing excessive amount of air pollution in its big cities and it is necessary for this country to invest on more environmental products, especially in transportation system which release a numerous level of air and noise pollution into the environment. It seems, it will be an appropriate approach for this country to produce or import Electric/Hybrid vehicles, but which car will be more compatible with Iran’s society, environment and people situation is still vague, in order of answering this question we designed our model in which 4 most globally popular Hybrid/Electric has been analyzed based on experts’ ideas. In general, descriptive-analytic method is used, the survey community is included all experts in the field of environmental management and sample size is obtained using non-random objective method (10 experts have been questioned) for prioritizing between different cars based on an analytic hierarchy process. The results showed that based on the experts’ perspective, fully electric vehicles are would rather be more compatible with Iran’s situation than Hybrid ones. The most significant feature that is contributed to Electric vehicles is about their high level of fuel efficiency and the least amount of pollution attributed to their Electric engine, which means they will release no pollution into the air. We finally based on the results, suggested some strategies, among which replacing old and low efficient fuel vehicles, placing excessive tax on regular cars and Tax exemption(for driving, importing and manufacturing electric cars) are the practical approaches for government in order to engage people buying-using more efficient cars. Keywords: Electric / Hybrid Vehicles, Air Pollution, Urban Transportation

This article focuses on the introduction of electric vehicles in Norway and how electrical cars are understood culturally in relation to conventional car use. Theoretically, elements of social practice theory and the analysis of processes of domestication are combined to frame practical, cognitive, and symbolic dimensions of electric car use. The empirical data consists of individual and focus group interviews with electric car users. The analysis unpacks the implications of user-designated meaning in driving practices, competencies considered necessary when driving electric cars, and the material aspects regarded as critical features of electric car driving. Preliminary findings suggest that the practice of electric car driving alters user habits by making transportation needs more salient and raises both the technological and energy consumption awareness of users.


Subject Impact of electric vehicles on oil demand. Significance Even with high sales, electric vehicles (EVs) will have limited impact on oil demand over the next decade. However, by 2040 the cumulative impact could be large, potentially representing more than 11 million barrels per day (b/d) of displaced fuel demand. While EVs are proving successful as light-duty vehicles (LDV), they are not yet penetrating the heavy-duty vehicle (HDV) sector where current EV ranges are a constraint. Growth in HDVs could offset any improvement in fuel efficiency on future oil demand. Impacts The belief that EVs are the technology of the future could affect investors' perception of the oil industry's growth prospects. Positive consumer reception of the new sub-40,000-dollar EV models could boost investment in lithium-ion battery production. High EV sales bode ill for alternative transport technologies such as hydrogen-fuel-cell cars Social mobilty services replacing private-vehicle ownership in the long term would transform EVs prospects.

The plug-in hybrid electric vehicle not only has the advantages of low emissions from electric vehicles, but also takes advantage of the high specific energy and high specific power of petroleum fuels, which can significantly improve the emissions and fuel economy of traditional vehicles. Studying its comprehensive energy consumption evaluation method is an important part of analyzing the economics of plug-in hybrid electric vehicles. This paper first puts forward the concept of statistical energy consumption and then proposes an innovative calculation method of plug-in hybrid electric vehicle energy consumption based on statistical energy consumption by referring to and analyzing the energy consumption test regulations of the United States, the European Union, and China. Given the two use case assumptions of charge depleting mode priority and charge sustaining mode only, considering the fuel consumption and the energy consumption that converts electrical energy consumption to fuel consumption, the probability density function of travel mileage distribution and energy consumption is derived. Finally, the interpretation and analysis of statistical energy consumption evaluation results are carried out.

Fuel price crisis has caused people to demand a car that is having a low fuel consumption without compromising the engine performance. Designing a naturally aspirated engine which can enhance engine performance and fuel efficiency requires optimisation processes on air intake system components. Hence, this study intends to carry out the optimisation process on the air intake system and airbox geometry. The parameters that have high influence on the design of an airbox geometry was determined by using AVL Boost software which simulated the automobile engine. The optimisation of the parameters was done by using Design Expert which adopted the Box-Behnken analysis technique. The result that was obtained from the study are optimised diameter of inlet/snorkel, volume of airbox, diameter of throttle body and length of intake runner are 81.07 mm, 1.04 L, 44.63 mm and 425 mm, respectively. By using these parameters values, the maximum engine performance and minimum fuel consumption are 93.3732 Nm and 21.3695×10-4 kg/s, respectively. This study has fully accomplished its aim to determine the significant parameters that influenced the performance of airbox and optimised the parameters so that a high engine performance and fuel efficiency can be produced. The success of this study can contribute to a better design of an airbox.
