The working principle of the automobile fuel pump control unit mainly includes the following aspects:
Working principle : The core of the fuel pump control unit is the electric motor, which drives an impeller or piston through rotation or reciprocating motion, the fuel is extracted from the tank and pressure is applied to ensure that the fuel smoothly flows through the fuel pipeline, and finally to the injector or carburetor

Intelligent control : The fuel pump control unit realizes intelligent control through the ECU, which can accurately control the work of the oil pump according to the running state of the engine, load, speed and other parameters. When the engine starts, the ECU will immediately start the oil pump, so that it begins to supply oil; During normal driving, the oil supply pressure and flow rate of the oil pump will be adjusted in real time according to the needs of the engine
Energy saving and protection : The fuel pump control circuit includes overvoltage protection mechanism and fault diagnosis function. The overvoltage protection mechanism automatically cuts off power when the fuel pump pressure exceeds a predetermined limit, preventing system damage. The fault diagnosis function monitors the working status of the fuel pump in real time through the ECU. Once an anomaly is detected, the fault indicator will remind the driver to repair
