The fuel injection pump is mainly composed of four parts, namely pump oil mechanism, fuel supply regulating mechanism, driving mechanism and fuel injection pump body. The pump oil mechanism includes the plunger coupling, the oil outlet valve and so on; the oil supply regulating mechanism refers to the rack type oil quantity regulating mechanism or the fork type oil quantity regulating mechanism; the driving mechanism includes the camshaft and the tappet assembly, etc. the injection pump body is the installation matrix of the above three, and requires it to have enough strength, stiffness and sealing, and is convenient for it. Disassembly, adjustment and maintenance.


In summary, there are four aspects:


1, constant pressure oil supply: the injection pump should raise the low pressure oil sent by the oil pump to a certain pressure, then through the high-pressure oil pipe to the injector, in order to obtain good spray quality.

2, timing fuel supply: the fuel injection pump must ensure that the oil supply and fuel supply duration will start at the prescribed time. For multi cylinder engines, the injection timing and duration of each cylinder should be equal.
