摘　　要：利用零维热力学模型对直接喷射分层燃烧转子发动机工作过程进行模拟计算,得到了燃烧室内工质温度、压力随偏心轴转角的变化和性能参数曲线,并与文献[5]中的计算结果进行了比较。结果表明:该模型可满足工程应用的需要,可作为直接喷射分层燃烧转子发动机初步或改进设计的分析工具。A comprehensive computer simulation has been developed to predict the performance of a direct-injection stratified-charge rotary combustion engine by means of the zero-dimensional thermodynamic cycle model. With giving the model,the chamber pressure and temperature are available during a complete engine cycle. By the chamber pressure,the overall engine performance parameters can be calculated. The model can be used as an analytical tool for the preliminary design and development of the direct-injection stratified-charge rotary combustion engine.
