中文摘要:
      在固定柴油机压缩比和燃烧室容积的前提条件下,提出通过改变燃烧室缩口率及内部形状,实现柴油机各排放生成物量变的研究思路。运用计算流体动力学(CFD)分析方法,对所设计的3种不同的燃烧室进行缸内工作过程的仿真分析,得出不同形状的燃烧室对缸内气相流场、温度场及排放生成物的影响规律。
英文摘要:
      This paper put forward the research thought of realizing the different amount emissions of diesel engine by changing the necking coefficient and inner geometry of combustion chamber,under the condition of keeping compression ratio of diesel engine and volume of combustion chamber invariable.Simulation analyses of working process of three kinds of different combustion chambers designed in the paper were carried out by using CFD numerical simulation method.And the influence rule on in-cylinder gas flow field,...
