2. Product introduction
The water level sensor in the container transmits the sensed water level signal 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, sends "" Open ""close" command to ensure that the container reaches the set 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.
The function of the water temperature sensor is to convert the cooling water temperature into an electrical signal, which is input to the ECU as follows:
3.1. Correct the fuel injection quantity; increase the fuel injection quantity when the temperature is low.
3.2. Correct the ignition advance angle; increase the ignition advance angle at low temperature, and delay it in order to prevent deflagration at high temperature.
3.3. 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.
3.4. Affect the EGR valve.
