Abstract [en]

To have knowledge about the exhaust temperature is of great importance in several ways. Knowing the exhaust temperature means that it is easier to protect the catalyst and turbine from too high temperatures but it also important in controlling the turbine power.In this thesis a physically based model of the engine out temperature is developed. The model is built up by two different cylinder pressure models and one engine out temperature model. Measurements has been made using a test engine at Linköping University. These measurement has then been used to  parameterize and validate the model. Since the measurements of the engine out port temperature are not showing reasonable temperatures, the temperatures in the pipes has been used for validation. That makes the results less reliable since no heat transfer between the port and pipe are considered in the model.
