Automobile engine temperature sensor

Car engine is a one of the most important car , its temperature for a car 's fuel consumption also has a decisive influence . Not to say that high temperatures will fuel more, in fact, the temperature is too low will lead to an increase in fuel consumption . Car engine work required to have normal temperatures ( 80 to 90 ) , Coolant Temp Sensor on the engine is particularly important. If the temperature is too high , the engine cooling system can automatically change the cooling water , increase the heat , remove excess heat ; Conversely, reducing the circulation of cooling water to maintain the necessary temperature . To achieve the main components of the cycle automatically change the engine temperature Coolant Temperature Sensor, thermostat valve thermostat and magnetic fan. Cold start , the magnetic fan is stopped , the thermostat valve is in the down state , the engine coolant in the engine water jacket only in small cycles , easy to heat , while computers were affected Crankshaft Sensors temperature index , will be issued to increase fuel injection, increasing the idle valve opening instruction , increase the engine speed is conducive to allow the engine to heat up quickly ; temperature is normal , the fuel injection quantity and idle valve opening are restored to normal. When the temperature exceeds 80 to 90 degrees ( of the vehicle slightly different) , the thermostat valve is opened , the engine water jacket through which coolant flows through the radiator thermostat valves bigger radiator circulation of air generated by the vehicle flow , away a lot of heat , to maintain normal temperature of the coolant . Slow or even stop , but if the speed does not stall , no flow of air to help dissipate heat , the engine will quickly heat up, then issued a directive to the magnetic temperature sensor helps radiator cooling fan starts .
