摘 要: 汽車尾氣是大氣污染的主要來源之一。 世界上發(fā)達(dá)國家的汽車尾氣排放法規(guī)日趨嚴(yán)格， 未來汽車必須達(dá)到低排放、超低排放， 甚至零排放的要求。 汽車尾氣催化凈化技術(shù)被證明是最有效的控制汽車排放污染的方法之一。 新發(fā)展的尾氣催化凈化技術(shù)， 如密偶催化劑、 HC吸附催化劑以及稀薄燃燒條件下的NOx吸附還原催化劑等的應(yīng)用，可滿足國外未來更嚴(yán)格的排放法規(guī)的要求。 同時(shí)概述了我國目前汽車尾氣凈化器行業(yè)的發(fā)展概況， 指出了我國汽車尾氣凈化器在產(chǎn)業(yè)化方面的不足以及努力方向。

Abstract:Automobile exhaust is one of the main sources of the air pollution. All over the world the regulations of vehicle emission in the developed countries are getting strict increasingly. In the future, the vehicle should meet low emission, ultra low emission and even zero emission regulation. Catalytic removal technology has been proved to be one of the most effective ways to eliminate the automobile emission. The latest application and advances in the exhausts catalyst, such as closed-coupled catalyst, HC adsorbed catalyst, NOx storage reduction catalyst under lean-burn condition can meet abroad future stricter emission regulation law. Current developments and deficiencies on the industrialization of the native catalytic converter trade were summarized and the directions of development were proposed.
Key words: catalytic removal; vehicle emission; closed-coupled; HC adsorbed catalyst; lean-burn; NOx storage reduction
