长城哈弗柴油机故障2例

2 cases of hover diesel engine failure in the Great Wall

文章对长城哈弗柴油机故障举例说明,得出结论:第一对于电控柴油机和缸内直喷汽油机,有些元件出现的故障现象一样,要加以总结,但有些是柴油机特有的故障特点,如油路故障需要考虑是否进了空气,油路是否有杂质,要注意是先排除。第二对于有故障码提示的故障,主要对电控元件原理要熟悉,检测电压或电阻就能判断故障所在,证明维修人员基本功要扎实。

This article gives an example of the fault of the Great Wall haffer diesel engine,and concludes:first,for the electric-controlled diesel engine and the in-cylinder direct-injection gasoline engine,the failure of some components should be summarized,but some of them are unique fault characteristics of the diesel engine.If the oil road failure needs to consider whether there is air,whether there are impurities in the oil road,it should be taken care of first.The second is the failure of the failure code prompt,mainly familiar with the principle of the electronic control element,the detection voltage or resistance can be judged where the fault,proving that the basic skills of the maintenance personnel must be solid.
