Research and Test of the Electronic Fuel Semi-Direct Injected Two-Stroke Gasoline Engine

The electronic injection technology for two stroke gasoline engine,which comprises the layout of electronic fuel injection system and the choosing method and fixed position of fuel injector were introduced in this paper.The research device of electronic injection system for two-stroke engine was designed.The dynamometer test results showed that the injection timing had a large effect on the fuel consumption and it must be accurately and precisely controlled,when the engine was working at low load.As the semi-direct fuel injection system was used,the fuel consumption rate was obviously decreased at full load in comparison with the carburetor two-stroke engine,and the power and torque had a slight increasing.
