在更换柴油机喷油嘴偶件的过程中,过去由于我们忽视了调压的反作用,在未放松调压螺钉前,就拆出或装上喷油嘴偶件,这样势必造成损伤喷油器体和喷油嘴的结合面或定位销,使喷油器漏油,也影响了机身的清洁。由于喷油器漏油,致使油压降低、喷油雾化不好、敲缸而影响发动机的性能。因此,在向喷油器体上装喷油嘴偶件时,必须首先放松调压螺钉,
In the replacement of diesel nozzle couplings in the past, because we neglected the reaction pressure regulator, before not relaxing the pressure screw, it is removed or fitted with nozzle fittings, it is bound to cause damage to the injector body And nozzle combination of surface or positioning pin, so that the fuel injector leakage, but also affect the body’s clean. As injector spills, resulting in lower oil pressure, spray atomization is not good, knocking cylinder and affect the performance of the engine. Therefore, when installing a nozzle on the injector body, the regulator screw must be loosened first,
