Abstract

Internal combustion engine with mechanical supercharging has a pulsation damper, which is attached to compressor (1) at suction side and pressure side. The compressor, the suction side pulsation damper and the pressure side pulsation damper are each encased with a sound insulation. The sound insulation consists of an inner component (5,9,11), which is made of absorption foam and an outer component (4,10,12), which is made of plastic.
