Abstract [en]

A turbocharger is currently widely used to boost performance of an IC-engine. The turbine and compressor of the turbocharger have an influence on the propagation of low frequency engine pulsations in intake and exhaust systems. In this paper a passive acoustic effect of automotive turbo-compressor is in focus. Current wave action models developed in CMT for computation of gas exchange processes in IC-engines are implemented to study the wave transmission through the compressor. The models are validated with experimental data measured in the turbocharger test facility at KTH CICERO. The results are presented for different operating conditions of the unit.
