摘　　要：从车用柴油机的欧Ⅳ/Ⅴ排放法规出发,指出满足该法规必须采取排放后处理装置,介绍了用以处理NOx排放的稀NOx吸附器(LNT)和选择性催化还原装置(SCR),及控制颗粒物(PM)排放的氧化催化器(DOC)和PM过滤器(DPF),分析了这些后处理装置的主要技术特点及应用情况,并认为今后的后处理装置的发展趋势是不同后处理装置的综合使用。It is pointed out in the paper that after-treatment technologies must be adopted in order to meet Euro Ⅳ/Ⅴ standards, and several after-treatment devices are introduced, such as LNT（ Lean NO, Trap）, SCR（ Selective Catalytic Reduction）, DOC （Diesel Oxidation Catalyst） and DPF（ Diesel Particulate Filter）. Technology characteristic and application situation of those after-treatment devices are also been analyzed in detail. It is indicated in the paper that different after-treatment devices applied compreheusively will be the trend of after-treatment devices in the future.
