The invention relates to an arrangement for recirculating and cooling exhaust gas of an internal combustion engine ( 2 ), in particular of a diesel engine in a motor vehicle, wherein the internal combustion engine ( 2 ) has an exhaust line ( 3 ) with an exhaust gas turbine ( 6 ) and an intake line ( 4 ) with a charge air compressor ( 8 ) which is driven by the exhaust gas turbine ( 6 ), wherein an extraction point ( 11 ) for branching off an exhaust gas recirculation line (EGR line 5 ) is arranged downstream of the turbine ( 6 ) and a recirculation point ( 12 ) for recirculating the EGR line ( 5 ) is arranged upstream of the compressor ( 8 ), and wherein at least one exhaust gas heat exchanger ( 13 ) and an EGR valve ( 14 ) are arranged in the EGR line ( 5 ). It is proposed according to the invention that a charge air throttle element ( 17 ) is arranged in the intake line ( 4 ) and that the EGR valve ( 14 ), the recirculation point ( 12 ) and the throttle element ( 17 ) are formed as an integrated component ( 19 ). |
