1发动机调整不当发动机使用一段时间后,由于震动和磨损,使喷油泵的技术参数发生变化,这些变化经常引起启动困难,需要重新调整参数。调整喷油泵的供油提前角时,拆下喷油嘴一端的高压油管螺母,旋松另一端的高压油管螺母,使油管水平放置,管口朝上,将手油门放在供油位置转动飞轮,使高压油管充满柴油,再缓慢转动飞轮,当管口油面开始上升时,观察飞轮上的供油刻线,供油提前角应为16~20°。若刻线超前或滞后,应进行调整。调整一般使用增加或减少垫片的方法。增加垫片,延迟供油,减少垫片,提
1 Engine Misalignment After a period of engine operation, variations in the fuel injection pump specifications due to vibration and wear often lead to start-up difficulties and require readjustment of the parameters. When adjusting the fuel supply advance angle, remove the high-pressure tubing nut at one end of the injector and loosen the high-pressure tubing nut at the other end, so that the tubing is horizontally placed with the nozzle facing upward and the hand throttle on the fuel supply position. Turn the flywheel , So that the high-pressure fuel pipe full of diesel, and then slowly turn the flywheel, when the nozzle surface began to rise, observe the fuel on the flywheel engraved line, fuel advance should be 16 ~ 20 °. If the line advance or lag, should be adjusted. Adjust the general use to increase or decrease the gasket method. Increase the gasket, delayed fuel supply, reduce the gasket, mention
