摘要
在人类社会可持续发展的大背景下,汽车节能一直是人们关注的焦点,发动机作为汽车的心脏,其节能技术研究也至关重要。文章对汽车发动机节能的原理进行简要介绍,对汽油机缸内直喷、稀薄燃烧、可变压缩比、可变配气系统等发动机节能关键技术及研究现状进行总结分析,并提出对未来发动机节能技术发展的展望,期望为后续研究提供理论基础与参考方向。
In the context of sustainable development of society,automobile energy conservation has been the focus of people's attention,the engine as the heart of the automobile,its energy saving technology research is also very important.This paper briefly introduces the principle of automobile engine energy saving,summarize and analyze the key technologies and research status of engine energy saving,such as gasoline direct injection,fuel stratified injection,variable compression ratio and variable valve system,and put forward the prospect of future development of engine energy saving technology,hoping to provide theoretical basis and reference direction for subsequent research.
