Abstract [en]

The demand for lower emission engines forces the car industry to build moreefficient engines. Turbocharged engines are on the rise, and better understandingof the heat transfer and efficiency of the turbocharger is needed to build better ones. A lot is known about the overall efficiency of the turbocharger, but not much is known about where the heat losses are located and how they interact with each other.

This thesis presents a one dimensional model for heat exchange in the tur-bocharger and investigates how the heat flows from the hot exhaust gases to the cold intake air. Data is gathered by performing tests on a single scroll turbocharger in an engine test bench at Linköping University. The tests are focused on operating points where the air mass flow is low and neither the compressor nor the turbine works adiabatically.

The results show that it is possible to estimate the heat flows together withthe efficiency of the turbine and compressor using only known parameters, elim-inating the need to add any new sensors to the engine.
