摘要
该文介绍了开发的一种降低轻型车 NOx排气污染物的排气再循环系统以及该系统进行的发动机台架及整车排放试验 ,给出和分析了排放试验结果 .研究表明 ,该系统对降低轻型车的 NOx排放物有显著效果 .
An exhaust gas recirulation(EGR)system that can decrease the pollutant of NOx from an light duty motor vehicle is developed in this Paper. The results of engine and vehicle emission tests are presented and the relevant analyses illustrate that this devloped EGR system can reduce NOx exhuast emission greatly.
