Patent ID: 7219661

Claim:
An exhaust gas recirculation means for an internal combustion engine with an air supply line which has an air cooler and which is connected to the air inlet of the internal combustion engine, and with an exhaust pipe which is connected to the exhaust gas outlet of the internal combustion engine, the exhaust pipe being connected by way of an exhaust gas recirculation line to the air supply line, and the exhaust gas recirculation line being connected in the flow direction to the air supply line upstream from the air cooler, characterized in that the air cooler ( 13 ) has a bypass air line ( 31 ); wherein in the exhaust pipe ( 14 ) in the flow direction upstream from the branch ( 20 ) of the exhaust gas recirculation line ( 16 ) there is the turbine ( 17 ) of the exhaust gas turbocharger ( 18 ) for driving the compressor ( 21 ) of the exhaust gas turbocharger ( 18 ), which compressor is located in the air supply line ( 12 ) in the flow direction downstream from the mouth ( 23 ) of the exhaust gas recirculation line ( 16 ) and upstream from the air cooler ( 13 ); and the air supply line ( 12 ) in the flow direction downstream from the branch ( 34 ) of the bypass air line ( 31 ) and upstream from the air cooler ( 13 ) has a cooler air butterfly valve ( 33 ) in the cooler supply ( 35 ).
