Full specification Copper & Stainless steel Engine Block Temperature Sensor
- PRODUCT DETAIL
The function of the water temperature sensor is to convert the temperature of the cooling water into an electrical signal.
After entering the ECU:
1. Correct the fuel injection amount:
Increase fuel injection at low temperatures.
2. Correct the ignition advance angle: Increase the ignition advance angle at low temperatures and postpone to prevent detonation at high temperatures.
3. Affect the idle speed control valve: When the temperature is low, the ECU controls the idle speed control valve according to the water temperature sensing signal to improve the speed.
4. Affect the EGR valve;
Water temperature and level sensor structure principle
The water temperature and water level sensor is composed of a temperature controller part and a water level control part. It is also accompanied by a pressure reducing device in front of the electric valve and a rotary muffler heater for heating
Water temperature and level sensor principle
The water level sensor in the container transmits the sensed water level signal to the controller. The computer in the controller compares the measured water level signal with the set signal to get the deviation. Then according to the nature of the deviation, an "on" and "off" instruction is issued to the electric water supply valve to ensure that the container reaches the set water level. After the water inlet procedure is completed, the computer in the temperature control section issues an "open" instruction to the electric valve that supplies the heat medium, so the system begins to heat the water in the container. When it reaches the set temperature. The controller sends a command to close the valve, cut off the heat source, and the system enters the thermal insulation state. Programming process, ensure that the system has not been reached safety level, the electric control valve controls the heat source is not opened, thereby avoiding the occurrence of heat loss accident.
