Write the second part of the vehicle emission factors. Write the third part of the automobile exhaust emissions control and management. Fourth cent wrote to diesel exhaust emissions from gasoline engine differences. Write the fifth part of the diesel engine exhaust gas purification and particulate collector, and the analysis of the automobile emission pollution and human survival environment, introduced from the engine combustion, structure design, fuel and other technology and strengthen the vehicle repair and maintenance, the development of new environmentally friendly cars and other measures, control vehicle emission, reduce air pollution. After 20 years of reform and opening up, Chinas rapid increase in the number of private cars, the car begins to enter common people family life. The car needs of rapid growth is fueled by 2002 China an important force for economic growth. Last year the auto manufacturer and sales of 3250000 vehicles, an increase of 37% in 2001. Last year than in addition, passenger vehicle sales exceeded the 1000000 mark, jum
