| 摘 要： | 柴油机具有良好的动力性和经济性,但NOx和颗粒排放高.为此,概述了柴油机废气再循环技术(EGR)的特点、控制方法,分析了存在的问题.为了降低柴油机的NOx排放,研究了不同工况下EGR率对柴油机性能的影响.试验结果表明:柴油机小负荷时,宜采用大EGR率;大负荷时,宜采用小EGR率;随着EGR率提高,空燃比降低,排气温度提高,采用EGR可以有效地降低NOx排放.

| Abstract: | Diesel engine have good powerful and economical efficiency, but more NOx emission. This paper introduced the characteristics and control methods of diesel engine exhaust recycle technology , analyzed it problem. For reducing NOx emission of an engine, the effects of EGR ratio on performances of diesel engine under different operating conditions were studied. The test results showed that the NOx emission was reduced when using EGR. |
