Injection Pump Drive Ass’y

The main function of the fuel injection pump drive component of the excavator is to provide constant pressure fuel supply and timed fuel supply.
The fuel injection pump is an important component on the diesel engine of the excavator, and is considered the “heart” of the diesel engine. The fuel injection pump assembly is usually composed of components such as the fuel injection pump and governor installed together as a whole. The governor ensures the low-speed operation of the diesel engine and limits the maximum speed, ensuring a certain relationship between injection quantity and speed. The fuel injection pump is the most important part of the diesel engine, and any problems with it can cause the entire diesel engine to malfunction.
The functions of the fuel injection pump include:
Constant pressure fuel supply: The fuel injection pump raises the low-pressure oil supplied by the fuel pump to a certain pressure, and then delivers it to the injectors through high-pressure oil pipes to achieve good diesel atomization.
Timed fuel supply: The fuel injection pump should ensure that fuel is supplied at the specified time and continuously, which is crucial for ensuring the normal operation and performance of the engine.
In conclusion, the excavator fuel injection pump drive component ensures the normal operation and performance of the diesel engine through constant pressure fuel supply and timed fuel supply.
