满足欧Ⅳ排放的不同柴油机技术路线对润滑油规格发展的影响

DIFFERENT TECHNOLOGY CHOICES OF DIESEL TO MEET EURO IV EMISSION AND ITS IMPACTS ON LUBRICANT SPECIFICATIONS

介绍了为满足欧Ⅳ排放的柴油机所采用的两种不同技术路线:选择性催化转化(SCR)技术和微粒捕集器(DPF)技术,并比较了两种技术的优缺点。同时分析了两种柴油机技术路线对欧洲、美国润滑油规格发展以及对中国润滑油市场的影响。

In this paper, two different technologies of diesel to meet Euro Ⅳ emission are introduced： Selective Catalytic Reduction （SCR） and Diesel Particulate Filter （DPF）. The two technologies have different strong points and weak points. The impacts of different technologies on lubricant specifications in Europe, U.S.A and China are also analyzed.
