缸内直喷式汽油机及其关键技术

GDI ENGINES AND ITS KEY TECHNOLOGY

介绍了缸内直喷式汽油机的原理及其燃烧系统的特点,包括燃烧方式,喷油器特性参数和缸内气流运 动对燃烧系统的影响,缸内直喷汽油机稀燃技术尚未解决的排放问题,以及目前汽油机缸内直喷技术的发展概况。

This paper introduces the principle and characteristics of combustion system of GDI engines, including the effect of combustion types, parameters of injector and air flow in-cylinder in process of the combustion, and the high HC emission, which is not solved yet, by lean burn in GDI engines. The results will be helpful for the further research on GDI technology.
