摘　　要：针对增压直喷柴油机开展全面净化的研究,设计了一套废气再循环(EGR)结合机外废气净化(EGC)系统,该系统能在柴油机较宽转速和负荷范围内有效净化废气排放。试验结果表明,EGR结合EGC技术在降低柴油机的废气排放方面具有很大突破。The technology about cleaning exhaust gas emission has been researched and used in a turbocharged direct-injected diesel engine. An Exhaust Gas Recirculation (EGR) with External Exhaust Gas cleaning (EGC) system has been designed and this system can reduce emission on a large scale of velocity and load. According to the results of the experiments, it has proved that EGR with EGC system can perform a great aspect at reducing diesel emission considerably.
