Abstract

The invention relates to a charging device for an internal combustion engine (1) and a method for operating the charging device. The charging device has an exhaust gas turbocharger (4) and a regenerative supercharger (12), wherein the regenerative supercharger (12) has a compressor-turbine (13) and an electromechanical motor-generator (14 ), the electromechanical motor-generator (14) is coupled to the compressor-turbine (13). Here, the high pressure side (HD) and the low pressure side (ND) of the compressor-turbine (13) can be connected via line connections and valve means (15a-d) to the fresh air The charge air supply line (8) downstream of the machine (6), wherein the regenerative supercharger (12) can be operated via a valve arrangement (15a-d) and a motor-generator (14) at least in the enhanced mode of operation and Switching between regenerative operating modes, wherein the regenerative supercharger can be operated on the one hand in booster operating mode as a compressor driven by the motor-generator (14) in order to increase the pressure, or alternatively operated as a turbine driven by the flow of charge air for energy recovery via the motor-generator (14).

Description

technical field [0001] The invention relates to a charging device for an internal combustion engine having an exhaust-gas turbocharger and to a method for operating the charging device. Background technique [0002] Exhaust-gas turbochargers are increasingly used to increase the power in internal combustion engines, especially in motor vehicles. Against the background of increasingly stringent laws and regulations in this regard, exhaust-gas turbochargers are increasingly used for the purpose of reducing the power consumption of the internal combustion engine while maintaining the same power level or even achieving an increased power level. structural size and weight while reducing consumption and thus CO 2 emission. The principle of operation consists in utilizing the energy contained in the exhaust gas flow to increase the pressure in the intake tract of the internal combustion engine and thereby achieve an improved charge of air oxygen (Luft-Sauerstoff) into the combust...
