摘要
柴油机燃烧室的设计，通常以经验设计为主，要通过实机实验，比较得到较优燃烧室形状，周期长，费用高。本文通过模拟不同形状燃烧室内的三维流场，分析缸内气流运动规律，评述了不同燃烧室形状的优缺点。
The DI combustion chamber is used to designed by experience and must be validated by experiments. This paper provide a three - dimensional flow field numerical simulation in different com- bustion chambers. The characteristics of the flow field are analyzed. The merits and demerits of the dif ferent combustion chambers are analyzed too.
