ABSTRACT:
To increase the efficiency of energy transfer from an auxiliary compressed air supply (12, 13, 14) to the compressor blades or vanes (22) of an exhaust gas turbosupercharger compressor (1), auxiliary drive vanes (23) are formed at the compressor wheel, located for reception of streams of compressed air from the auxiliary compressed air supply, the auxiliary compressed air escaping to the compressed air outlet manifold of the turbosupercharger for introduction to an inlet of an internal combustion engine (ICE) if extra charging air is required thereby. The auxiliary compressed air injection nozzles may be formed with bores in a part (17) of the compressor housing or as grooves (40) in the circumference thereof, fitted against a closing flange (39) of another portion of the compressor housing. The auxiliary vanes or blades may be located at or close to the periphery of the compressor wheel (7), either on the front side, where the main compressor blades (22) are located, or on the back side thereof. Preferably, and odd number of injection nozzles (e.g. five, seven, nine) is used.
