柴油车具有动力性强、经济性好、热效率高等特点，在交通运输等领域得到广泛使用。随着汽车排放法规的日益严格，柴油车必须加装后处理系统才能满足其限值。本文重点介绍了柴油氧化催化器（DOC）、氮氧化物选择性催化还原（SCR）、稀燃NOx捕集器（LNT）和柴油机颗粒捕集器（DPF）等后处理技术的研究现状，以及联合净化技术的主要研究方向。
시유차구유동력성강、경제성호、열효솔고등특점，재교통운수등영역득도엄범사용。수착기차배방법규적일익엄격，시유차필수가장후처리계통재능만족기한치。본문중점개소료시유양화최화기（DOC）、담양화물선택성최화환원（SCR）、희연NOx포집기（LNT）화시유궤과립포집기（DPF）등후처리기술적연구현상，이급연합정화기술적주요연구방향。
Because the characteristic of diesel in dynamic performance, economy, high thermal efficien-cy,etc.,it is widely used in transportation and other fields.With the emission regulations increasingly strin-gent, the diesel can only meet the limit using aftertreatment devices.This paper mainly introduces the re-search state like diesel oxidation catalyst(DOC), nitrogen oxides(NOx)selective catalytic reduction(SCR), lean NOx trap(LNT) and diesel particulate filter(DPF), and the research direction of combined purification technology.
