Abstract
A supercharger device for an internal combustion engine, including an exhaust gas turbocharger and a recuperation charger having a compressor turbine and an electromechanical motor-generator coupled thereto. The compressor turbine is connectable on the low-pressure side thereof to a charge air supply line and on the high-pressure side of the compressor turbine to both the charge air supply line and an exhaust gas tract of the engine. The recuperation charger is able to be switched at least between a booster operative mode and a recuperation operative mode. The recuperation charger may be operated as a compressor driven by the motor-generator for increasing pressure in the charge air supply line in the booster operative mode, or driven by at least a portion of a charge air mass flow, the exhaust gas mass flow, or both, and operated as a turbine so as to recover energy by the motor-generator.
