单缸柴油机在使用中常发生起动困难的故障,主要是燃油供给系统和压缩系统方面的原因造成。碰到这种情况,通常先从起动时喷油嘴能否发出“咕咕”的喷油声入手检查判断。一、如听不到油嘴喷油的“咕咕”声时,表明无油进缸或进入气缸内的燃油无力。这时,可将喷油泵泵体上的放气螺钉(指190柴油机,195则为进油管接螺栓)拧松,观察螺孔处是否有燃油流出。1.如无燃油流出,表明低压油路不正常,应检查
Single-cylinder diesel engines often occur in the start-up difficulties of failure, mainly due to fuel supply system and compression system. In this case, usually start with the nozzle can issue “” cuckoo “injection sound to start judging. First, if you can not hear the ”Nozzle injection“, ”Cuckoo " sound, that no oil into the cylinder or into the cylinder of the fuel weakness. In this case, loosen the bleed screw on the pump body (referring to 190 diesel engine and 195 to the inlet pipe bolt) to see if there is any outflow of fuel at the screw hole. 1. If there is no fuel outflow, indicating that the low-pressure oil is not normal, should be checked
