Fuel injection pumps are mainly used in automobile diesel engines. The fuel injection pump assembly is usually a whole composed of fuel injection pumps, governors and other components installed together.
Among them, the governor is a component that guarantees the low-speed operation of the diesel engine and the limitation of the maximum speed, and ensures a certain relationship between the injection volume and the speed.
The fuel injection pump is the most important part of the diesel engine and is regarded as the "heart" part of the diesel engine. Once it goes wrong, the entire diesel engine will malfunction.
