摘　　要：本文介绍了作者开发研制的微机版内燃机缸内多维气流运动模拟程序ＳＵＮ－Ⅰ的数学模型及程序的结构，探讨了开发微机用大型模拟程序所出现的问题及解决的途径和方法，采用作者开发的计算程序，对柴油机缸内气流运动进行了具体模拟计算，并与在ＣＲＡＹ巨型机上用ＫＩＶＡ－Ⅱ程序的计算结果进行了对比，结果表明，作者开发的微机用模拟程序ＳＵＮ－Ⅰ，已基本实现了ＫＩＶＡ－Ⅱ的功能，其计算精度及使用方便性与ＫＩＶＡ－Ⅱ程序基本相同。A mathematical model on multidimensional gas flow in cylinder of internal combustion engine and its program structure of personal computer are introduced in this paper. The problems occurred when the simulation program was developed and their solutions are also discussed. By using our program the gas flow motion in cylinder of diesel engine was practically calculated. The calculated outcomes, compared with those by using KIVA Ⅱs, show the calculated precision and the convenience are the same as the KIVA Ⅱs on the whole.
