Description
 

Fuel injection pump is an important part of automobile diesel engine. The fuel injection pump assembly is usually a whole composed of fuel injection pump, governor and other components installed together. Among them, the governor is a component that ensures the low-speed operation of the diesel engine and the limitation of the maximum speed, and ensures a certain relationship between the injection quantity 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 fails, the entire diesel engine will malfunction. The fuel injection pump can be mainly divided into three types: plunger fuel injection pump, fuel injection pump-injector and rotor distribution fuel injection pump. Among them, the plunger type fuel injection pump is the oldest and the most widely used, with high reliability; the fuel injection pump-fuel injector is a combination of the two, which is directly installed on the engine cylinder head, which can eliminate the high-pressure fuel pipe. The adverse effects brought by (requires an additional drive mechanism on the engine); the rotor distribution fuel injection pump has only one pair of plungers, and mainly relies on the rotation of the rotor to realize the pressurization and distribution of the fuel. It has small size, light weight, convenient use, Features such as low cost. The fuel injection pump is mainly composed of four parts: the pump oil mechanism, the fuel supply adjustment mechanism, the driving mechanism and the fuel injection pump body. Among them, the oil pump mechanism includes the plunger coupler, the oil outlet valve couple, etc.; the oil supply amount adjustment mechanism refers to the rack-type oil amount adjustment mechanism or the fork-type oil amount adjustment mechanism; the driving mechanism includes camshafts, tappet assemblies, etc. ; The fuel injection pump body is the installation base of the above three, and it is required to have sufficient strength, rigidity and sealing, and to facilitate disassembly, adjustment and maintenance.

 
 
Characteristic

1. The oil is supplied according to the working order of the diesel engine, and the oil supply of each cylinder is uniform.
2. The fuel supply advance angle of each cylinder should be the same.
3. The oil supply duration of each cylinder should be equal.
4. The build-up of oil pressure and the stop of oil supply must be rapid to prevent dripping.
5. It has the characteristics of small size, light weight, convenient use and low cost.
