Abstract

According to the system requirement of a certain type of aviation piston engine, the reconstruction and matching of fuel injection system is carried out. The schematic design of the air-assisted injection assembly and the improvement of pressure regulator assembly are completed. After that, the air-assisted direct injection system is studied experimentally. The results reveal the effect of injection parameters and injection pressures on the system flow characteristics and spray characteristics. The effects of gasoline and kerosene on the actual engine performance are compared. The test results show that the self-designed air-assisted direct injection system can meet the system fuel injection requirements. In addition, the effect of injection pressure on the spray width is more noticeable than other spray characteristics.
