装载机一旦柴油机出现问题，就会直接导致装载机无法正常工作，但是对于柴油机而言，启动困难是我们常常与到的故障，那么在遇到启动困难时应该如何处理呢？

一、观察柴油机的启动转速。当按下起动按钮而不能启动时，可能出现以下几种现象：起动转速正常；起动转速降低；曲轴因启动电机不工作，或起动电机空转而不转动。上述现象除起动转速正常外，都属于蓄电池或起动电路技术状况不良造成的故障现象，故应检查蓄电池和启动电路技术状况。
Observe speed diesel engine starts. When you press the start button and can not start, it may appear the following phenomenon: the normal starting speed; starting speed is reduced; crankshaft due to the starter motor is not working, or not turning the starter motor idling. In addition to the above phenomena outside normal starting speed, are all caused by poor symptom technical condition of the battery or the starter circuit, so you should check the technical condition of the battery and start circuit.
二、启动转速正常，但是发动机不能启动，应注意查看柴油是否进入气缸，即观察排气管是否排烟和倾听发动机有无爆发生。若起动时无烟排出，也无爆发声，表明柴油没有进缸，原因是喷油泵不泵油，或低压油路不供油?？上燃觳橛氏淠谑欠裼杏?，然后拧松喷油泵上的放气螺钉，检查油路是否堵塞和有空气，如上述检查正常，再进一步检查喷油泵是否泵油。
Start speed is normal, but the engine does not start, you should pay attention to see if the diesel into the cylinder, that observe and listen to the exhaust pipe of the engine exhaust is whether the outbreak of the students. If the starter smokeless exhaust, no outbreak of sound, indicating that there is no diesel into the tank, because the fuel pump does not pump oil, or low pressure oil is not oil. Can first check whether there is oil in the mailbox, and then loosen the bleed screw on the fuel pump, check the oil and air is blocked, such as the examination is normal, check the fuel pump if the pump further oil.
