摘　　要：在介绍和分析发动机电喷控制系统原理的基础上 ,对 NISSAN NA2 0 S化油器式发动机进行了电喷改造研究 .通过发动机的改进设计和电子控制汽油喷射系统的采用以及匹配实验 ,使该机的动力性和经济性明显改善 ,其排放已达到欧 排放标准 .本研究表明 。A carburetor of Model NA20S gasoline engine in Nissan is altered based on the study and analysis of the principle of electronic fuel injection system. The power and economy of the engine are well improved and its exhaust emission complies with EURO Ⅱ by well designing the engine,adopting the electronic fuel injection system and matching experiment.It is feasible that carburetor gasoline engines are directly altered by the electronic injection systems.
