Predictive Thermal Management of a Combustion Engine
Sprache des Titels:
Temperature control is very important for combustion engines as temperature is a critical factor both for chemical reactions and mechanical stresses. Traditionally, temperature control is performed by feedback of a global quantity, the coolant temperature, which however is a poor indicator of specific temperatures. The use of electrical pumps opens new possibilities for thermal control, in particular in terms of efficiency, but also of pollution, especially in the cold start phase. This diploma thesis shows that predictive control and the use of electric coolant pumps allow regulating specific temperatures - here as example the cylinder head temperature.
