Discharge gas turbo charger for charging a combustion engine and method for charging a combustion engine using such a discharge gas turbo charger

摘要

The turbocharger has a compressor (1) for compressing fresh air for a supercharged internal-combustion engine e.g. diesel engine. The compressor includes a housing (3), an inlet (4) for the fresh air to be compressed and an outlet (5) for the compressed fresh air. The housing includes a cooling device (6) i.e. water cooling device, for cooling the fresh air. Cooling channels are provided in the housing, where the channels form a cooling mantle and lead coolant through the housing. An independent claim is also included for a method for compressing fresh air for a supercharged internal-combustion engine using an exhaust-gas turbocharger.
