1、开启油箱开关，拆下来输油泵进油管，看油排状况，假如油排迅速，表明是正常的，假如油排断断续续查油道。

1. Turn on the oil tank switch, remove the oil inlet pipe of the oil pump and check the oil discharge condition. If the oil drain is fast, it indicates that it is normal. If the oil drain is intermittent, check the oil passage.

2、低压油排通畅后，可以用手压泵油道中的气体，开启泵头放气螺丝，直没有汽泡时，方能扭紧放气螺丝。

2. After the low-pressure oil is drained smoothly, the gas in the oil passage can be removed with the hand pump, and the air release screw of the pump head can be opened until there is no bubble.

3、明确油道通畅，柴油发动机提供系统软件没有气体后，可拆开来油泵档板，旋转控制摇杆，拨动油泵拉杠，看拉杠是不是灵便和柱塞弹簧是不是破裂。在拉杠灵便和柱塞弹簧没断的状况下，可运行柴油发动机中速运行十分钟，再有断火状况时，可以用一只铜榔头轻轻地敲打输油泵大螺帽，一面敲一面听柴油发动机响声，假如响声异常，表明输油泵活塞和推杆发卡，开展维修或拆换。

3. Make sure that the oil passage is unobstructed and there is no gas in the system software provided by the diesel engine, remove the oil pump baffle plate, rotate the control rocker, and toggle the pull rod of the oil pump to see whether the pull rod is flexible and whether the plunger spring is broken. Under the condition that the pull rod is flexible and the plunger spring is not broken, the diesel engine can run at a medium speed for 10 minutes. If there is a fire cut-off condition, a copper hammer can be used to gently tap the big nut of the oil pump, while tapping and listening to the noise of the diesel engine. If the noise is abnormal, it indicates that the piston and push rod of the oil pump are jammed, and maintenance or replacement can be carried out.

4、如不成则应考量是油嘴不雾化，油泵柱塞弹簧和弹簧座破裂，卡住不运行，或者柴油内有水。拆下来油嘴总成查验开启压力和雾化，假如油嘴总成是正常的，可让客户用洁净柴油装进壶中用油路旁接法开展实验。若再有断火状况应考量是发动机状况。

4. If not, it should be considered that the nozzle is not atomized, the plunger spring and spring seat of the oil pump are broken and stuck, or there is water in the diesel oil. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the customer can fill the pot with clean diesel oil and carry out the experiment by oil way side connection. If there is a broken fire condition, the engine condition should be considered.

5、拆下来喷油器总成，旋转曲轴数圈，即有水喷出来，表明缸盖，缸体有裂痕或沙孔，碰到这类状况时，可向客户表述或向柴油发动机公司反应。归属于发动机状况就不作叙述。

5. Remove the fuel injector assembly, rotate the crankshaft for several turns, and the water will spray out, which indicates that there are cracks or sand holes in the cylinder head and cylinder block. In case of such situation, you can express to the customer or respond to the diesel engine company. The engine condition is not described.
