本文论述柴油机喷油器检修后必须做喷油器供油及喷油压力测试。如果测试不合格需进行必要的调整。因为压力过高,发动机会产生异响,使发动机功率降低,同时也会加剧喷油器柱塞偶件的磨损。压力过低会引起喷雾不良,发动机排烟增大,使发动机功率降低。笔者详细地总结了喷油器供油及喷油压力的测试方法。
This article discusses the diesel injector must be done after the fuel injector and fuel injection pressure test. If the test failed to make the necessary adjustments. Because the pressure is too high, the engine will have abnormal sound, so that the engine power is reduced, but also exacerbate the injector plunger wear. Low pressure can cause poor spray, the engine exhaust increases, so that the engine power is reduced. The author summarizes in detail the fuel injector and fuel injection pressure test methods.
