摘　　要：发动机沉积物的生成从来源上讲主要有燃料和润滑油,本文就从燃料和润滑油为切入点来研究减少沉积物生成的技术方法.通过对发动机台架运行试验表明:燃料的不完全燃烧以及机油的高温氧化是沉积物生成的主要途径.所以,选用优质的柴油燃料和添加柴油机油油品清净剂是减少柴油机EGR管路沉积物生成的技术方法.Engine sediment generation from the source of fuel and lubricating oil,this paper from fuel and lubricating oil as a starting point to study the reduction of sediment generation technology.The results show that the incomplete combustion of fuel and high temperature oxidation of oil are the main ways of sediment formation.Therefore,the selection of high quality diesel fuel and the addition of diesel oil detergent are the technical methods to reduce diesel EGR pipeline sediment formation.
