Description

The water temperature and water level sensor is composed of a thermostat part and a water level control part. It is also matched with a decompression device in front of the electric valve and a rotary muffler heater for heating. The water level sensor in the container will sense the water level. The signal is transmitted to the controller, and the computer in the controller compares the measured water level signal with the set signal to obtain the deviation, and then according to the nature of the deviation, issues "open" and "close" commands to the water supply electric valve to ensure that the container reaches Set the water level. After the water inlet program is completed, the computer in the temperature control part sends an "open" command to the electric valve supplying the heat medium, and the system starts to heat the water in the container. to the set temperature. Only when the controller issues a command to close the valve and cut off the heat source, the system enters the heat preservation state. In the process of programming, it is ensured that the electric regulating valve that controls the heat source does not open when the system does not reach the safe water level, thereby avoiding heat loss and accidents.

Characteristic
 

1. Correct the fuel injection quantity; increase the fuel injection quantity when the temperature is low.
2. Correct the ignition advance angle; increase the ignition advance angle when the temperature is low, and delay it in order to prevent deflagration when the temperature is high.
3. Affect the idle speed control valve; when the temperature is low, the ECU controls the idle speed control valve action according to the water temperature sensing signal to increase the speed.
4. Affect the EGR valve;
5. The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal
