| 摘 要： | 我国柴油车（尤其是重型柴油车）污染问题突出，亟须重点控制.为此，对我国重型柴油车后处理技术的主要研究进展进行了综述与展望.结果显示:我国自柴油车国Ⅳ标准实施以来，后处理技术已经成为柴油车尾气污染控制的必备技术.目前发展出的主要后处理技术包括用于控制CO和HC排放的柴油机氧化催化剂（DOC）、用于控制PM排放的柴油颗粒捕集器（DPF）、用于控制NOx排放的选择性催化还原技术（SCR）.我国国Ⅳ和国Ⅴ阶段主要采用SCR技术路线控制重型柴油车污染排放，而国Ⅵ阶段严苛的标准要求为柴油车污染物排放控制带来巨大挑战，需要将多种后处理技术进行耦合，并且需要将后处理系统与发动机系统进行融合.除柴油车新车外，我国在用柴油车也需要有针对性地开展污染治理，主要涉及NOx和PM高效协同减排技术和排放在线监管技术.

| Abstract: | Diesel vehicles, especially heavy-duty diesel vehicles, have caused serious air pollution problems in China. Therefore, the development and application of diesel exhaust aftertreatment technologies in China were reviewed in this paper. Since the implementation of Chinese Ⅳ standard, the aftertreatment technologies have become necessary for the emission control of diesel vehicles. The developed aftertreatment technologies mainly include diesel oxidation catalyst (DOC) for controlling CO and HC emissions, diesel particulate filter (DPF) for PM emission control, and selective catalytic reduction (SCR) for the control of NOx emissions. During the Chinese Ⅳ and Ⅴ stages, SCR was the main aftertreatment technology for the emission control ofheavy-duty diesel vehicles. Due to the stringent requirements of Chinese Ⅵ standard, the combination ofdifferent aftertreatment technologies is needed for the emission control, and the aftertreatment system needs to be integrated with the engine system. In addition to new vehicles, the in-use diesel vehicles need targeted emission control, which mainly involves two types of technologies:simultaneous control technology for NOx and PM and on-line monitoring technology for emissions. |
