火花点火发动机燃烧研究新进展

评述了火花点火发动机燃烧研究的新进展。着重讨论了油束引导直喷式汽油机和HCCI汽油机研究取得的成果和存在的问题。为使上述直喷式汽油机得以实用,必须重视对可变气门机构、低射程喷油器(如压电晶体式)及基于气缸压力的控制系统等关键部件的研究。

New Progress of Combustion Research for Spark Ignition Gasoline Engine

The new progress of combustion research for SI gasoline engine was introduced, and the acquired achievements and the existed problems of spray-guided direct injection gasoline engine and HCCI gasoline engine were mainly discussed. The key parts such as variable-valve actuation, low penetration injector (e.g. piezoelectric) and cylinder pressure based engine control system had to be researched in order that the above-mentioned gasoline engine could be applied
