摘　　要：以单缸四冲程LPG发动机为研究对象,为了能直观地分析其工作过程中各参数的变化而构建仿真模型。基于AVL fire软件对其进行模拟计算,通过与试验结果对比其工作过程中缸内压力、温度等数据,验证了仿真结果的有效性,为LPG发动机燃烧过程的完善提供了参考。A simulation model of single cylinder four stroke LPG engine was established for analyzing its parameters variation of the working process. The simulation model is calculated based on the AVL fire software. The calculated results of pressure and temperature of working process are compared with experimental results, and then the effectiveness of simulation results is verified. This can provide a reference for the perfection of combustion process of LPG engines.
