Product Description

Application areas:

At present, my country will fully implement the National VI emission standards for heavy-duty diesel vehicles. Using common rail technology, the high-pressure fuel pump delivers high-pressure fuel to the common rail pipe, and the common rail pipe delivers high-pressure fuel to the injectors of each cylinder through the high-pressure fuel pipe. The actual operating state of the engine is detected by various sensors, and the fuel injection volume, fuel injection time, fuel injection rate, and fuel injection pressure are accurately controlled by ECU calculation, analysis, and processing.
Vane pump, camshaft, tappet body and metering valve are one of the main components of high-pressure oil pump system.
vane pump function:
1. Deliver a certain pressure of fuel from the fuel tank of a diesel vehicle to the high-pressure fuel pump;
2. Deliver fuel circulation to cool the high-pressure oil pump.

Camshaft function:
1. Connect the diesel engine to transmit torque;
2. Convert the rotary motion of the camshaft into linear reciprocating motion and drive the tappet body;
3. Drive vane pump.

Function of tappet body:
1. The movement of the cam is smoothly transmitted to the plunger;
2. Adjust the oil supply time of the plunger appropriately.

metering valve function:
1. Control the amount of oil entering the rail pipe to meet the requirements of the pressure setting of the common rail system;
2, together with the rail pressure sensor to form a closed-loop control of the rail pressure.
