摘要
柴油机以良好的性能而得到普及,其在动力性、燃料经济性及耐久性等方面具有独特优势。而柴油车尾气中含大量污染物,其中,碳烟颗粒物和以及氮氧化物(NOx)是柴油机尾气排放中两种最主要的污染物。因此需要开发一种柴油车尾气处理净化技术。本文主要介绍了柴油车排放后处理技术的研究进展及四效催化技术的发展前景。
Diesel engines are popular for their unique advantages in power performance,fuel economy and durability.Diesel exhaust contains a large number of pollutants,among which carbon black particles and nitrogen oxides(NOx) are the two main pollutants in diesel exhaust emissions.Therefore,it is necessary to develop a diesel vehicle exhaust treatment and purification technology.This paper mainly introduces the research progress of diesel vehicle emission post-treatment technology and the development prospect of four-effect catalytic technology.
