摘要

设计了一种带冷却系统的柴油机废气再循环(EGR)装置

并进行了EGR及冷EGR对柴油机燃烧和排放性能影响的试验研究.结果表明

在各种工况下

EGR都可以显著降低NO

排放

当EGR率为15%时

中高负荷下NO

排放可以降低50%左右

当EGR率为30%时

高负荷下NO

排放可以降低75%左右.但是

EGR率的增加会给柴油机的动力性、燃油消耗率、烟度、CO和HC排放带来不同程度的负面影响

使柴油机的最大爆发压力及放热率峰值下降且出现的位置略微后移.使用冷EGR、中高负荷下

排放可以减少15%左右

烟度排放略有降低.

Abstract

An EGR unit with a cooling system was developed for a diesel engine and the effects of cooled EGR and uncooled EGR on combustion and emission were investigated experimentally. The results show that EGR can reduce NO

emission of the diesel engine significantly under various operation conditions. NO

emission can decrease by about 75% at the EGR rate of 30% under high loads but the increase of the EGR rate has negative influence on torque output

brake specific fuel consumption

and emissions of smoke

CO and HC. Moreover

peak values of combustion pressure and heat release rate decrease. The cooled EGR system can reduce NO

and smoke emission more effectively compared with the uncooled EGR system under high and normal loads.
