Abstract
In this paper, turbocharger heat transfer losses have been modelled using a lumped capacitance model coupled with one-dimensional whole-engine simulation software. The data from the simulations of a turbocharged Diesel engine, with and without the turbocharger heat transfer model, have been compared with experimental measurements performed in an engine test bench. The analysis is focused on studying the influence in turbocharger outlet temperatures and predicting the engine performance. The main result of the study is the improvement in the prediction of both compressor and turbine outlet temperatures (up to an improvement of 70Â K). The results from the model allow analysing how heat transfer losses are split in the turbocharger and quantifying the importance of heat transfer phenomena in turbocharger efficiency, at full load conditions and as a function of engine speed.
