car Water tank engine water temperature sensor structure
Its interior is a semiconductor thermistor, the lower the temperature, the greater the resistance; on the contrary, the smaller the resistance. The electronic control unit according to the measured change in the temperature of engine cooling water,
As a fuel injection and ignition timing of the revision numbers.
car Water tank engine water temperature sensor principle
The water level sensor in the vessel, the water level sense signal to the controller,The computer controller within the measured level signal and the set signal for comparison, the deviation,Then according to the nature of the deviation, to issue the "on" "off" command to the electric water valve, and the vessel reaches a set level.
After the water is complete, the computer makes part of the thermostat "on" command to the heat medium supplying electric valve, then the system starts to heat the water in the container.The set temperature.The controller only issue the command off valve, cut off the heat source system into the insulating state. Program preparation process,Ensure that the system does not meet the security situation under water,Electric control valve to control the heat source does not open the valve,Thus avoiding the occurrence of heat loss and accidents.
The role of car Water tank engine water temperature sensor
It is installed in the engine block or cylinder head water put in direct contact with cooling water. Thus the measured engine coolant temperature. The electronic control unit according to the measured change in the temperature of engine cooling water, the lower the temperature, the greater the resistance; Conversely smaller resistance. Electronic control unit according to the change in the measured temperature of the engine cooling water as a fuel injection and ignition timing of the revision numbers.
