摘　　要：随着排放法规的逐渐加严,汽车的排放控制工作已成为国家环保部门、汽车科研、检测机构和车企共同关注的课题。本文简述了汽油机主要排放污染物的形成机理和危害,重点从机内净化、排气后处理和燃油质量优化等方面分析了当前汽油车主要排放控制技术,并对下一阶段汽油车的排放控制技术的发展趋势进行了展望。With the gradual tightening of emission regulations, the emission control of automobiles has become a common concern of the national environmental protection department, automobile scientific research, testing institutions and automobile enterprises. This paper briefly describes the formation mechanism and harm of the main pollutants emitted by gasoline engines, and focuses on the analysis of the current main emission control technologies of gasoline passenger vehicles from the aspects of in-engine purification, exhaust after-treatment and fuel quality optimization. The development trend of control technology is prospected.
