Automotive auxiliary electronic pump is a water pump used to assist with operation of the engine cooling system. Its working principle is described as follows:

1. Sensor detection: Whenever the engine temperature reaches a certain level, the sensor will detect it and send a signal to the control unit of the vehicle.

2. Control unit response: After receiving the signal from the sensor, the control unit will control operation of the auxiliary electronic pump depending on parameter settings.

3. Water pump startup: The control unit will start operation of the auxiliary electronic pump through the circuit.

4. Auxiliary cooling: After the auxiliary electronic pump starts operation, it will extract coolant from the engine cooling system and deliver it to the radiator to help cool down the engine.

5. Circulation control: The auxiliary electronic pump will continue to work until the engine temperature drops to a defined level, after which the control unit will stop operation of the water pump.

Through the above processes, the automotive auxiliary electronic pump can effectively assist in cooling of the engine cooling system, thus ensuring normal operation of the engine and extending its service life.
