摘　　要：本文根据天然气发动机混合气的形成特点,把天然气发动机分为预混合燃烧型和非均质扩散燃烧型,并分析了这两种天然气发动机的技术特点、燃烧特点与排放等性能。本文重点介绍了实现非均质扩散燃烧的不同型式高压缸内直喷天然气发动机技术及其性能特点,最后提出非均质扩散燃烧天然气发动机技术需要研究的相关问题。According to the features of the mixture formation in natural gas engine, natural gas engine can be classified as two types: premixed combustion type and heterogeneous diffusive combustion type. This paper respectively analysed emission exhaust performance and charateristics of mixture formation and combustion in the two types of natural gas engine. And emphasis was given to the technology of direct injection natural gas in cylinder (DING) which can fulfill heterogeneous diffusive combustion. Finally, author brought forward some technology problems to be solved further for heterogeneous diffusive combustion natural gas engine.
