【Abstract】 With the development of automobile industry, people have made much effort on resource saving and environmental protection. Based on the requirement of economy and emissions for gasoline engines in the near future, some effective methods are put forward for meeting stricter regulations in this paper. Up to now, exhaust gas recycle and catalytic instrument are widely used on electronic controlled gasoline engines. Variable exhaust system and dynamic exhaust gas recycle can obviously reduce emissions. Using adaptive control of air fuel rate in the range of lean burn and the whole operating mode, the combustion process of gasoline engines is improved. The succesful application of electronically controlled, fuel injection technique on two stroke gasoline engines is an important development and innovation.更多还原
