柴油机经过一段时间的使用,技术性能变差,要想恢复至原来的功率而且易于启动,在检修中必须注意以下3组精密部件。供油时间精度高不同型号的柴油机,根据设计要求有不同的供油时间。供油时间太早,因活塞要继续向上,而燃气又迫使它向下行,这样不仅抵消了一部分机械能,降低了功率,而且还因撞击使活塞销、销孔、连杆衬套、轴瓦等零件过早 Diesel engine over time, poor performance, in order to restore the original power and easy to start, in the repair must pay attention to the following three sets of precision components. High precision fuel supply time Different types of diesel engines, according to the design requirements have different fuel supply time. The fueling time is too early, because the piston to keep up, and gas forced it down, so that not only offset some of the mechanical energy, reducing power, but also because of the impact piston pin, pin hole, connecting rod bushings, bushings and other parts Premature
