摘　　要：以氢气为汽车代用燃料,以方便性、实用性和可靠性为基本要求,设计出一套氢-汽油双燃料模式发动机电控系统,并对发动机运行中油气转换过程进行了细致研究,提出一套油气转换控制策略。根据ECU发出的指令,可以使发动机分别独立工作在两种燃料模式下,且在发动机不停机的状态下平稳地进行油气切换。Based on hydrogen for the automotive alternative fuel, and convenience, practicability and reliability as the basic requirements, the paper designs a set of electronic control system of hydrogen/gasoline dual fuel mode engine. This paper researches the switch process of the two fuel carefully, and brings a set of switch strategy. According to the ECU instruction, the engine can independently operates in two kinds of fuel modes, and switches the fuel smoothly in operating condition.
