1台ZAXIS360-3H型挖掘机配置日本五十铃6HK1型高压共轨电喷柴油机。该柴油机经常出现启动困难、启动后运转不稳、冒黑烟、动力下降、自动熄火现象。根据上述现象,初步判断为燃油供给系统故障。该柴油机有2级柴油滤清器来保证3～5μm颗粒的过滤精度(传统柴油机的滤清器只能过滤
A Taiwan ZAXIS360-3H excavator configuration Japan Isuzu 6HK1 high-pressure common rail EFI diesel engine. The diesel engine often appears difficult to start, start running instability, black smoke, power decline, automatic flameout. According to the above phenomenon, initially judged as a fuel supply system failure. The diesel engine has two diesel filters to ensure the filtration accuracy of 3 ~ 5μm particles (the traditional diesel filter can only filter
