一般柴油机出厂有三定: 一是定时——就是射油泵的各缸间隔角度相等,射油泵装在柴油机上时,供油提前角符合原设计规定。二是定量——就是说射油泵的每个柱塞偶件在单位时间供给的油量是相等的,并且符合原设计规定。三是定压——就是各缸压缩终了发火压力是相等;各缸喷油咀压力是一致的。一台柴油机,理论上满足上述三要素,就
General diesel engine factory has three set: First, timing - that is, the angle of each cylinder of the fuel pump is equal, when the fuel pump is installed on the diesel engine, the fuel supply advance angle meets the original design requirements. The second is quantification - that is, each plunger of the injection pump is supplied with equal amounts of oil per unit time and is in compliance with the original design regulations. The third is the constant pressure - that is, the pressure at the end of each cylinder compression is equal; the pressure of each cylinder nozzle is the same. A diesel engine theoretically satisfies the above three factors,
