摘　　要：建立了发动机启动过程仿真模型,根据试验结果对模型进行标定。重点分析了几何压缩比、倒拖扭矩、节气门、进排气门正时、进气包角、第1缸活塞初始位置以及壁面温度,对发动机启动过程的缸内压力、转速以及歧管压力的影响。结果表明,该仿真手段能够用于研究混合动力发动机启动过程,并且能够简单快捷地获得更多启动过程发动机状态参数。The simulation model of engine starting process was established,and the model was calibrated according to the test results.The effects of compression ratio,motor torque,throttle valve,intake and exhaust valve timing,intake cam profile angle,initial piston position of the first cylinder and wall temperature on cylinder pressure,engine speed and manifold pressure during engine starting process were analyzed.The results show that the simulation method can be used to study the starting process of hybrid electric engine,and more engine state parameters can be obtained easily and quickly.
