Fuel silent diesel generatorinjection pump (also called high pressure oil pump) is the "heart" of diesel engine, is the most important parts of diesel engine fuel supply system. Its function is to increase the pressure of the diesel engine, and according to the requirement of the diesel engine working process, timing, quantitatively to the fuel transportation fuel.

On the basic requirement of fuel injection pump:

1) according to the requirements of the diesel engine working cycle, regular supply of fuel.

2) based on the diesel engine working load size, quantitative supply of fuel oil, heavy load when the oil increase, decrease, conversely, and the evenness of each cylinder oil, general requirements each cylinder difference less than 3%.

3) oil supply and demand can rapidly, and can guarantee cut-out quickly, avoid injector produce dripping phenomenon. The structure of fuel injection pump a lot, now commonly used is to use the plunger type fuel injection pump. Multi-cylinder machine for fuel pump can be in a separate shell (namely monomer pump). Can also be combined in a shell (i.e., the overall pump).
