  • Dual-charged internal combustion engine and method for operating the same
    Patent number: 7810329
    Abstract: The invention relates to an internal combustion engine, especially of a motor vehicle, which comprises an air path for intake air in which a mechanically driven charge unit (20), especially a compressor, which can be connected and disconnected by means of a coupling (36), an exhaust gas turbocharger (18), an intake pipe (32), connected to air inlets of a cylinder block (10) of the internal combustion engine, and a charge cooler (34) are mounted. One pressure outlet (35) of the mechanically driven charge unit (20 is directly connected to the intake pipe (32) and one pressure outlet (24) of the exhaust gas charger (18) is connected to an intake inlet (28) of the mechanically driven charge unit (20). The pressure outlet (24) of the exhaust gas charger (18) is connected to the intake inlet (28) of the mechanically driven charge unit (20) via an on-off butterfly valve (26) and upstream of said on-off butterfly valve (26) to the intake pipe (32) via a load butterfly valve (30).
