ABSTRACT:
The invention concerns a device for increasing the rotational speed of an exhaust gas turbo-charger on an internal combustion engine. The compressor casing of the exhaust gas turbo-charger is located in the engine air induction duct. The compressor includes a compressor impeller and a volute-shaped gas duct, a guide device being located in the induction duct upstream of the suction-side opening of the gas duct. In order to reduce the power consumption of the compressor during idling and lower part-load operation, the inducted air is guided into a bypass duct by means of the guide device, the bypass duct entering the induction duct downstream of the compressor. The compressor is partially evacuated by means of a pressure-reducing device located in the bypass duct.
