HIGH SPEED TEMPERATURE SENSORS IN EMISSION SYSTEMS OF COMBUSTION ENGINES

S. Augustin, F. Fröhlich, C. Ament, T. Güther
Abstract:
Temperature sensors used in emission systems of combustion engines must register enormous temperature differences within the shortest periods of time. This serves to protect the engine parts with respect to their temperature stability and to govern the energy efficient functioning of the engine. Numerical calculations according to the Finite Elements Method are used to estimate static-thermal measurement errors and dynamic characteristics primarily concerning medium specificity and construction of the temperature sensors. Prediction models are used to correct the dynamic behavior and to predict the medium temperature faster accurately.
