柴油机废气的排放与控制

Diesel Emission and Its Control

由于世界各国排放法规的日益严格,特别是对柴油机中氮氧化物和微粒的排放限制,使柴油机废气的排放与控制成为了近几年内燃机研究的焦点。氮氧化物和微粒对环境和人体的不利影响也越来越受到关注。本文试图对这方面的研究做一个简要的论述。

Due to the engine exhaust emission regulation continually being stringent in many countries in the world, especially for the emission limit of nitrogen oxide and particulate matter from diesel engine exhaust. How to control the diesel emission is becoming a key issue in recent years for the development of internal combustion engine. The negative influence of nitrogen oxide and particulate matter to environment and to human body has been paid more and more attention in recent days. This paper gives a simple overview of the state-of-the-art situation in diesel emission control.
