摘　　要：近几年我国汽车保有量的快速增长,汽车排放问题逐步凸显,为有效控制汽车排放总量,我国已对汽车相关排放法规进行了多轮次的加严。为满足排放法规,很多排放控制技术应运而生。本文主要对我国轻重型车现阶段主流排放控制技术进行了梳理,详细介绍了轻重型车各项机内净化技术以及机外后处理技术,并结合实际市场占有率,提出了典型技术路线建议,力求为汽车车型开发提供技术支撑。In recent years,the number of vehicles in China has grown rapidly,and vehicle emissions have gradually become prominent.In order to effectively control the total amount of vehicle emissions,China has tightened several rounds of vehicle-related emission regulations.To meet emission regulations,many emission control technologies have emerged.This paper mainly sorts out the current mainstream emission control technologies of light and heavy vehicles,introduces in detail the various in-machine purification technologies and external post-processing technologies of light and heavy vehicles,and proposes typical technical route suggestions based on the actual market share to provide technical support for the development of automobile models.
