摘要： 柴油车具有燃油消耗率低、转矩输出高、功率覆盖范围广等优点，在交通运输和工程机械
等领域得到广泛应用。随着汽车排放法规的加严，柴油车只有采用后处理装置才能满足未来严格的
排放法规。该文给出了欧洲、美国、日本和中国等国家或地区的汽车排放法规的发展趋势及其对油
品的要求；分析了满足相关法规的轻型柴油车和重型柴油车的排放控制技术路线；重点介绍了柴油车
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）和微粒捕集器（DPF）等
后处理技术的研究现状；对柴油车排放法规和后处理技术的未来发展进行了展望。

Abstract: Diesel engine has advantages of low fuel consumption, high torque output and wide power range,
and has been widely used in transportation and engineering machinery as a power. The diesel powered
vehicles can only meet future stringent emission regulations using aftertreatment devices. This paper compared
the different vehicle emission regulations in Europe, the USA, Japan and China, and analyzed in-cylinder and
aftertreatment technical approaches to meet the emission regulations for light-duty and heavy-duty diesel
vehicles. The research status of the mainstream aftertreatment technologies like diesel oxidation catalyst (DOC),
nitrogen oxides (NOx) selective catalytic reduction (SCR), lean NOx trap (LNT) and diesel particulate filter (DPF)
was described and discussed. The future development of the diesel emission regulations and aftertreatment
technologies was prospected.

Key words: diesel engine, emission regulation, aftertreatment, selective catalytic reduction (SCR), diesel particulate filter (DPF)
