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. Increase the oil pressure (constant pressure): increase the injection pressure to 10MPa ~ 20MPa.
2. Control fuel injection time (timing): fuel injection and stop fuel injection at specified time.
3. Control the fuel injection quantity (quantitative): According to the working condition of the diesel engine, change the fuel injection quantity to adjust the speed and power of the diesel engine.
4. It has sufficient strength, rigidity and sealing, and is easy to disassemble, adjust and maintain.
5. The fuel injection pump should not be disassembled or adjusted at will, especially the parts with seals.
