摘　　要：欧Ⅴ排放对中国汽车产业将是一个重要的技术拐点。依照该法规减少排放的目标,汽车厂家需要针对缩短催化剂起燃时间、改善稳态NMHC和NOX污染物等方面做大量的工作。研究表明,二次空气喷射系统、发动机管理系统优化及催化剂的改善是一个行之有效的技术途径。EuroⅤ regulation will be an important technology inflection point to the Chinese auto industry.In accordance with the laws and regulations to reduce emissions targets,the vehicle manufacturers need to do a great job to reduce the catalyst burning time and to improve the stable NMHC and NOX pollutants.The results show that the secondary air injection system,engine management system optimization and improvement of the catalyst are effective technical approaches.
