A device and method for enhancing the efficiency of an IC-engine supercharged by means of an exhaust gas turbocharger.

摘要

The arrangement has a compressor (15) in addition to the exhaust gas turbocharger (2) with its compressor wheel connected to the shaft of a high speed electric motor (16). The motor can perform extreme speed changes in fractions of a second, if required high revolution rates and has a maximum output power of about 5 to 30 kW and receives the required electrical drive energy from a machine (17) operated as a generator, which is connected to the engine's crankshaft and controlled by a regulator, and/or a battery. The additional compressor can supply additional air to increase the power. An Independent claim is also included for a method of increasing the power of an internal combustion engine with an exhaust gas turbocharger.
