【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。更多还原

【Abstract】 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 NOx 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 comprehensively will be the trend of after-treatment devices in the future.更多还原
