降低稀燃汽油机NOx排放技术进展

Technological Development of Reducing NOx Emission in Lean Burn Gasoline Engine

节能和环保的要求,使得稀燃技术越来越受到人们的重视。然而,由于稀燃的富氧燃烧,使得NOx排放降低较小。介绍了国内外降低稀燃汽油机NOx排放技术的进展情况。

Because of requirements of energy and environment, the lean burn technology has been paid more and more attention. However, NOx emissions are reduced a little because of rich oxygen combustion. The technological development of reducing NOx emissions are introduced in this paper.
