摘　　要：“发动机原理”课程中的均质充量压燃燃烧涉及大量化学动力学机理,学生理解较为困难,运用Chemkin软件搭建发动机均质充量压燃燃烧的仿真实验模型,通过修改相应参数,得到不同初始条件下的放热率、缸内温度、缸内压力等仿真结果,针对仿真结果进行分组讨论,得到相应结论,并将燃料扩展到天然气,分析参数变化对天然气发动机均质充量压燃燃烧的影响,激发了学生的兴趣,加深了学生对教学内容的理解。The homogeneous charge compression ignition in the course of Automobile Engine Principles involves a large amount of chemical kinetic mechanism which is difficult for students to understand.We can build a simulation experiment model of homogeneous charge compression ignition with the software Chemkin.By modifying the corresponding parameters,different simulative results of heat release rate,in-cylinder temperature,and in-cylinder pressure under different initial conditions are discussed in groups.The fuel can be replaced by natural gas,and parameter variables and their effects are analyzed for the homogeneous charge compression ignition of natural gas engines.The simulation experiment model has stimulated students'interest and deepened their understanding of homogeneous charge compression ignition..
