Research on the application and maintenance of the temperature sensor in the vehicle

The temperature of intake, exhaust, tail gas in the car engine reacts the state of the engine, which is an important parameter of running normal or not. The applications of the thermocouple temperature sensor in the vehicle detection is discussed in the paper from the principle and performance of thermocouple temperature sensor, the thermal state of the control engine, intake air temperature and exhaust temperature which use sensors to calculate gas flow, purification of row and exhaust gas is researched. By automotive electronic control systems, the engine can run at optimal working conditions.
