柴油机供油系的工作情况对发动机的功率影响很大,柴油机常见的故障有:起动困难、发动机无力、发动机运转不平稳,且有敲击声和运转时大量冒黑烟。1发动机起动困难当起动机以正常转速转动发动机曲轴,却不能起动着火,除了气缸压缩力不足和柴油品质低劣外,说明供油系有故障,应按燃油供给系统逐段查找原因。首先检查油箱油量是否充足,开关是否未开,油箱盖通气孔是否堵塞,旋开柴油滤清器上的放气塞,压动手压油泵,若放气塞处排出的柴油总是夹杂气
Diesel fuel supply system work on the power of the engine, diesel engine common faults are: difficult to start, the engine weakness, the engine is not running smoothly, and a large number of percussion and black smoke run. 1 engine start difficult When the starter to rotate the engine crankshaft at normal speed, but can not start the fire, in addition to insufficient cylinder compression force and poor quality of diesel, the fuel system is faulty, the fuel supply system should be section by section to find the cause. First check the fuel tank is sufficient, the switch is not open, the fuel tank cover vents are blocked, unscrew the diesel filter on the deflation plug, pressure hand pump, if the exhaust valve is always expelled diesel exhaust gas
