| 摘 要： | 为了降低涡轮增压柴油机NOx的排放量,设计了一套涡轮增压柴油机的EGR(Exhaust Gas Recircula-tion)系统,对该系统的主要部件文丘里管、EGR冷却器、EGR阀和旁通阀等进行设计,并对系统进行计算。结果表明:该EGR系统在全工况范围内的最大EGR率达40%以上,EGR温度冷却到了130℃以下。

| Abstract: | In order to reduce NOx emissions of Turbo-charged diesel engine,a EGR(Exhaust Gas Recirculation) system for turbo-charged diesel engine is designed.In this paper,the main components of the EGR system such as Venturi tube,EGR-cooler,EGR valve and bypass valve are designed as well.The calculating result of EGR system shows that the maximum EGR rate can reach 40% or more and the cooling temperature of EGR system can be reduced to 130 ℃ or below. |
