DC5V Car Water Temperature Sensor,
LPG Car Water Temperature Sensor,
CNG engine water temperature sensor
The function of the water temperature sensor is to provide an analog signal of temperature
change to the engine control unit (ECU) through its internal resistance change. Its power
supply voltage comes from the power supply provided by the ECU, and the signal returned
to the ECU is a linear change signal.
The main function of the water temperature is to inform the ECU of the engine temperature.
Its signal is important to the ECU and leads to different working methods of the engine under
different working temperatures:
1. Correct the fuel injection amount; when the temperature is low, increase the injection
2. Correct the ignition advance angle; increase the ignition advance angle at low temperature,
and delay the ignition to prevent deflagration at high temperature.
3. Affect auxiliary air regulator; at low temperature, ECU activates the auxiliary air regulator
to increase the RPM according to the water temperature signal.
