摘　　要：以一台 D6 114涡轮增压柴油机为研究对象 ,采用了一套带文曲利管的排气再循环系统进行了试验研究。试验结果表明 ,该系统在高工况下能克服平均排气压力低于平均进气压力的困难 ,方便地实现排气再循环。研究了在不同工况下柴油机的 NOx 排放、烟度和比油耗随 EGR率的变化规律以及 EGR的冷却效果对 NOxAn experimental investigation on the D6114 turbocharged diesel engine is carried out by using exhaust gas recirculation (EGR) system with a venturi tube.The results show that EGR can be realized conveniently with this system at higher load,while mean pressure of exhaust pipe is lower than that of intake pipe.This paper also shows the relationship between EGR ratio and NO x emissions,smoke and fuel consumption under various running modes.The effect of EGR cooling on NO x emissions is also described in this paper.
