摘要
综述车用柴油机氮氧化物机外治理的现状和发展趋势,介绍了降低柴油机NOx排放的机外措施:稀NOx技术、选择性催化还原技术、NOx的吸附技术及等离子体技术,分析了各种技术措施的各自特点和存在的问题。
The technology and recent development trend for nitrogen oxides in after-treatment of engine emission has been summarized. This paper focuses on off-engine measures to reduce diesel NOx emission such as lean NOx,SCR,NAC and Plasma.Features and adverse effect of each measures have been analyzed.
