摘要
文章对柴油发动机有害排放NO_X、HC、碳烟以及CO_2、的生成机理及其控制方式进行分析,立足于从车用柴油机排放污染物源头控制,重点分析机内净化和机外净化的优缺点,阐明了SCR选择性催化还原后处理技术治理柴油车的排放物的合理性和有效性。
This paper analyzes the formation mechanism and control methods of harmful emissions of NOX,HC,soot and CO2 in diesel engines,based on the control of source of pollutants discharged from vehicle diesel engines,focusing on the analysis of in-machine purification and off-board purification.Disadvantages,clarified the rationality and effectiveness of SCR selective catalytic reduction post-treatment technology to treat diesel vehicle emissions.
