汽油机均质压燃实际应用的最新进展(英文)

Recent Progress in HCCI Combustion for a Practical Usage as a Gasoline Engine

内燃机被广泛用于乘用车、卡车和公交车,其中燃用汽油的火花点火发动机主要用于乘用车。随着世界上乘用车的迅猛增长,亟待以最小的代价来改进汽油机的热效率。均质压燃(HCCI)燃烧技术一直被看作是有前途的新技术。为了解决这一挑战性课题,尽管许多研究人员一直在努力,但是其实际应用可行性至今还不清楚。本综述涵盖了至今检验过的技术方法,包括作者本人在"下吹式增压"(blow-down super-charged,BDSC)的HCCI方面的思想,以便帮助那些在这项技术方面愿意寻求新方法或者启动新研究的人员,为全球范围的节能而加快HCCI技术的实际应用。

Internal combustion engines are widely used in cars, trucks and buses. Among them, the spark ignition engine with gasoline fuel is mainly employed for passenger cars. As the number of cars is extremely increasing in the world, thermal efficiency in gasoline engines must be improved urgently with less expensive cost-up. The homogeneous charge compression ignition （HCCI） combustion system has been attracted as the promising and alternative combustion system to the spark ignition. Although many researchers have been conducted to this system to solve the challenging issues, the practical usage is still unclear. This review paper covers the technical methods examined so far, including the authors＇ idea of blow-down super-charged HCCI, to introduce interesting ideas helping researchers who like to find a new way or to start investigating on the system leading to accelerate the practical usage of HCCI systems for the energy saving in the world.
