介绍了二冲程汽油机上采用的电控燃油喷射技术，包括燃油喷射系统的设计与喷油器的选择方法，以及喷油器安装位置的确定方法。研制了一套可以适用于二冲程汽油机的电控燃油喷射系统的开发装置。试验表明：喷油时刻对于降低燃油消耗率影响很大，小负荷时必须对喷油时刻进行精确控制；采用电控低压半直接喷射系统后，发动机在全负荷时的燃油消耗率下降显著，同时功率与扭矩也稍有增加。

The electronic injection technology for two stroke gasoline engine,which com prises the layout of electronic fuel injection system and the choosing method an d fixed position of fuel injector were introduced in this paper.The research dev ice of electronic injection system for two-stroke engine was designed.The dynam ometer test results showed that the injection timing had a large effect on the f uel consumption and it must be accurately and precisely controlled,when the engi ne was working at low load.As the semi-direct fuel injection system was used,th e fuel consumption rate was obviously decreased at full load in comparison with the carburetor two-stroke engine,and the power and torque had a sli ght increasing.
