柴油机的供油提前角、柱塞偶件密封性及出油阀偶件密封性3项指标,一般都是采用单项分别检查的方法,不仅费时间多,而且比较麻烦。我们采用一次连续检查法,效果很好。现以195型柴油机为例说明其方法如下。先将高压油管从喷油器接头上拆开,然后拧开高压油管与油泵出口的接头螺母,放尽管中燃油,并转动高压油管使出油口向上,再拧紧 Diesel fuel supply advance angle, the plunger seal and the valve seal sealing three indicators are generally used individually check the method, not only time-consuming, but also more trouble. We use a continuous inspection method, the effect is very good. Now 195 diesel engine as an example of its method is as follows. First disconnect the high-pressure tubing from the injector connector, then unscrew the union nut of the high-pressure tubing and the pump outlet, and let the oil outlet up, despite the medium fuel, and tighten
