为降低柴油机的排放污染，使柴油机达到国IV以上排放要求，参考国际柴油机的排放技术，目前，主要有2条技术路线可供选择，即SCR技术路线和EGR技术路线。文章对这2种技术路线从结构特点、工作原理、优缺点进行比较分析，结果表明，柴油机在我国近期和远期，不同的车型应采取不同的技术方案，为我国柴油机达到国IV以上排放标准提供了参考。

To reduce the emission pollution of diesel engine and achieve the National IV emission standard, there are two technical routes to choose with reference to international emission technology of diesel engine： SCR and EGR. Two technical routes are compared and analyzed from structure characteristics, working principle, advantages and disadvantages. The results show that there are different technical solutions for diesel engines of different models in short and long term. It provides reference for diesel engine to achieve National Stage IV Emission Standard and above.
