car water temperature sensor composition structure And the impact on the car engine

There are many automotive sensors, This brings a certain degree of trouble to vehicle maintenance. Different sensor detection and repair methods are different. If you understand the principle of automotive sensors, Structure and its detection method, For the failure to solve a great help. Yaxun years of electronic design and production of automotive water temperature sensor. By analyzing the function of water temperature sensing and the production process, This article provides vehicle maintenance reference. This paper describes the automotive water temperature sensor on the car engine.

         Thermistor type water temperature by the thermistor temperature sensor and bimetal composition, As shown in Figure 1. Among them, the thermistor is the temperature of the transmitter information, Bimetal heating wire for receiving parts, the two series. (Copper probe) thermistor transmitter, That is, the water temperature sensor is installed in the water channel in contact with the cooling water, When the water temperature is low, Copper probe thermistor value is high, The current in the loop becomes smaller, Resistance wire of the heat is small, Bimetal will work properly, The water temperature indicator pin is in the low temperature zone (C zone). When the water temperature is high, The thermistor value becomes smaller, The current through the loop is large, Resistance wire high temperature fever, Bimetal bending deformation is large, The water temperature indicator needle points to the high temperature zone (H zone).

Water temperature table The water temperature sensor used is a negative temperature coefficient thermistor temperature sensor, It is installed in the cylinder cover water jacket, The water temperature sensor uses the water temperature sensor to sense the water temperature of the engine.

Automotive water temperature sensor performance is good or bad on the engine's fuel injection has a great impact, Serious will affect the combustion performance of automobile engine.

When the mixture is too thick or too thin, The combustion condition of the automobile engine deteriorates, Car engine is not easy to start, Running is not smooth, At this time should check the car water temperature sensor. Automotive water temperature sensor installed in the engine block or cylinder head of the water jacket,

The probe is in direct contact with the coolant, Used to measure the coolant temperature of an automotive engine. The temperature sensor used for the coolant thermometer is a negative temperature coefficient thermistor (NTC). Its resistance decreases with increasing temperature, A wire is connected to the ECU.
