摘要
为了减少污染物的排放,农用柴油机已全部达到国Ⅲ排放标准,即使用电控燃油喷射发动机。目前主要使用的技术路径有高压共轨和电控单体泵+废气再循环(EGR)两种。两种技术由于燃油喷射的方式不同,从排放的需要出发,对润滑油的品质也提出了不同的要求。
In order to reduce the emission of pollutants,the agricultural diesel engine has reached the china III standard,that is,to use of electronically controlled fuel injection engines.At present,the two mainstream technologies are high-pressure common rail and electronically-controlled unit pump+exhaust gas recirculation(EGR).Because of the different fuel injection methods,the two technologies put forward different requirements for the quality of the engine oil.
