Research on the Emission Control Technology for Diesel Engine Reaching Euro Ⅳ and Ⅴ

摘要

In recent years,diesel engines are dominant on the middle-duty and heavy-duty cars,and cars with diesel engines have become the development trend of the future automobile industry.In this paper,the exhaust components from diesel engines,the emission regulation system and two mainstream technology routes for Euro Ⅳ or Ⅴ are introduced.The emphasis is SWOT analysis to this two technology routes,and the specific application cases are given,which will promote the further development of emission control technology on diesel engines.%近年来柴油机不仅在中、重型汽车上占有统治地位,轿车柴油机化也成为未来汽车行业的发展趋势.本文介绍了柴油机排气组分,排放法规体系,以及达欧Ⅳ、Ⅴ的两条主流技术路线,重点对两条技术路线进行SWOT分析,并给出具体应用案例,这将促进柴油机排放控制技术的进一步发展.
