摘要
将一台柴油机改装为缸内直喷式汽油机,采用KIVA-Ⅱ软件时缸内直喷式汽油机的两个典型工况(分层燃烧和均质预混合燃烧)的燃烧过程进行了三维数值模拟。计算结果表明,采用分层燃烧和均质预混合燃烧具有不同的火焰传播方式和特点。
For a gasoline direct injection engine refitted from a diesel engine, the 3D simulation of combustion process with KIVA-II was achieved on two typical running points (stratified-charge combustion and homogeneous stoichiometrie combustion) .The results show that, these two ways of combustion have different types and characteristics of flame propagation and development.
