废气再循环在柴油机中的应用

本文回顾了废气再循环（EGR）在减少排放，特别是减少NOx排放上的潜力以及限定这一技术的应用范围。详细分析了RGR装置对柴油机的排放和性能的影响，通过深入分析，发现在柴油机进气中引入废气再循环（EGR），相当如置换了部分吸入的空气，这种方式能充分减少NOx的排放。因此，废气再循环的使用是最有效改善尾气排放的技术措施之一。

Using exhaust gas recirculation in Diesel engine

This paper is to review the potential of exhaust gas recirculation(EGR) to reduce the exhaust emissions, particularly NOx emissions, and to delimit the application range of this technique. A detailed analysis of results of EGR effects on the emissions and performance of Diesel engine, from the deep analysis, it was found that adding EGR to the air flow rate to the Diesel engine rather than displacing some of the inlet air. This way may allow exhaust NOx emissions to be reduced substantially. The use of EGR is, therefore, believed to be most effective in improving exhaust emissions.
