Study On Evaluation Of Energy And WTW Of Vehicle

With reform and openness deepening and social economy further development, energy and environmental question are outstanding day by day of our country. By the end of 2003, our country has already become the 2nd largest petroleum consumed country in the world; and there are 7 cities in our country in the most serious top 10 cities of pollution in the world. In recent years, following the automobile industry's high speed development, the automobile is playing a more and more important role in energy consumption and exhaust emission. In order to solve the problems of the auto industry of our country and the problems of the coordination development of the energy and environment, it is necessary to make the vehicle fuel development strategy of sustainable development.Make the development strategy of vehicle fuel need to carry on overall comprehensive appraisal on various kinds of vehicle fuel, at the basis of the circulation of various kinds of vehicle fuel /vehicle technology fuel, combine energy structure and production status of our country, through data analysis and model simulation, analyze environment and energy benefit of circulation of WTW, which may be used in many kinds of vehicle fuel at present and in near future, establish the foundation for proposing the development strategy of vehicle fuel. While studying the influence of the environment and energy in use of different vehicle fuel, we can't only remain during the course of investigating the automobile uses (namely study various kinds of automobiles and use the corresponding energy efficiency of fuel and situation of exhaust), and we should in the view of visual angle of the whole life cycle, investigate environment and energy benefit caused by the whole circulation of various kinds of fuel from raw materials exploit , processing , transportation , usage.This article analyzed the basic content in the whole course of life cycle of vehicle fuel evaluate at first, introduced domestic and international vehicle fuel life cycle evaluate current situation of studying, explained GREET model method in detail, on this basis, proposed our country vehicle fuel life cycle evaluate is divided into 3 stages: named present situation (2004) stage, near future stage (2008), long term (2020 years) stage.
