many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

In the process of promoting development China’s alternative fuel vehicle industry, government has issued preferential tax policies that are beneficial to its industrial development, and actively guided industrialization process. The purpose this paper is research analyze policy optimize allocation resources, promote rapid realization energy saving, emission reduction environmental protection. T...

Biofuel, a form of renewable fuel, has promising future, especially as the alternative fuel for transportation. Biofuel is usually blended with petroleum fuel and used in flex fuel engines. Since the characteristics of biofuel are quite different from those of the petroleum based fuel, it is very important to optimize the combustion properties for biofuel engines under different fuel blends. Th...

There is much interest in developing fuel cells for commercial applications. This interest is driven by technical and environmental advantages offered by the fuel cell, including high performance characteristics, reliability, durability, and clean power. A fuel cell is similar to a battery—it uses an electrochemical process to directly convert chemical energy to electricity. Unlike a battery, h...

The fuel consumption is an important component of the vehicle operating cost which is a significant component of the total transportation cost. Fuel consumption data are extensively used by transport planners, transport managers and other professional for various evaluation processes in overall gambit of sustainable transportation system. Accuracy of fuel consumption data is one of the key fact...

This report examines the possible safety benefits from driving in a manner that results in lower fuel consumption and emissions. It attempts to assess the potential of promoting additional motivations to drive safely – better fuel economy and other environmental outcomes, and reduced running costs. Reducing speeding, lower speed limits and modifying driving style were found to improve fuel econ...

Petrol powered traffic has replaced domestic heating and industry as the main causes for urban air pollution (Colvile, Hutchinson, Mindell, & Warren, 2001). Automobile combustion engines are responsible for the better part of a city’s CO2 and NOX pollutants. The amount of pollutants emitted by a vehicle largely depends on fuel consumption: the more fuel the vehicle consumes, the higher its emis...

Engine mathematical model can be used to simulate vehicle dynamic performance and fuel economy for vehicle design. Simulation of vehicle dynamic performance and fuel economy is based on mathematical model of engine. Least square method and multiple regression analysis were used to fit curve of external characteristics and universal characteristics when the test data of external characteristics ...
