摘要
针对15A型摩托车汽油机排气系统的流动过程进行了模拟计算，对计算中某些边界条件的计算方法进行了探讨，提出了作者的改进意见。计算结果与实测排气压力波基本吻合。在此基础上，分析了发动机的结构参数和运转参数对排气压力波的影响。
In this paper, computational non-steady gas flow process simulating of exhaust systemof Model 15A petrol engine has been made. Computing methods of some boundary conditions arediscussed and some improving suggestions are proposed. The computed results ngree mainly withmeasured pressure wave data. On this basis, effects of engine geometric parameters and operatingfactors on exhaust pressure wave are analyzed.
