Abstract
In this paper, the control requirements of the engine electronic control system (ECS) are proposed by analyzing the working principle of an air-assisted injection two-stroke kerosene spark-ignition engine. The software and hardware of the engine's electronic control unit are developed basing on the requirements of the control system. The control strategy of the control software for air-assisted injection system is studied in particular and was tested on a simulation test bench. At last, the engine electronic control system is tested and verified by the engine rig test, and the performance differences between the engine in the air-assisted injection mode and port fuel injection mode are compared. Tests on the simulation test bench and the engine test rig indicate that the electronic control system can meet the control performance requirements of this engine for electronic control systems, and the air-assisted injection system is able to improve the overall performance of the engine.
