由于柴油发动机的定时齿轮副、凸轮轴、随动柱、柱塞副、出油阀等零部件的磨损或高压油泵的安装不当,会使供油时间偏离正常范围,引起发动机性能的明显恶化。因此,及时地对供油时间迟、早做出正确的经验判断,并加以调整,对于节能和改善柴油机的工作状况是很必要的。下表可以帮助我们判断。 Due to the wear and tear of the timing gear pairs, camshafts, follower columns, plunger pairs, oil outlet valves and other components of diesel engines or the improper installation of high-pressure oil pumps, the oil supply time will deviate from the normal range, causing obvious deterioration of engine performance. Therefore, in time for the oil supply time late, early make the correct judgments, and to adjust for the energy saving and improving the working condition of diesel is necessary. The following table can help us judge.
