An exhaust re-circulation system has at least two exhaust (2,2') and two coolant openings (3,3'), with at least one connected via a flange (4,4') to a corresponding opening in the cylinder head. The remaining exhaust and/or coolant openings are each connected fluid- and gas-tight to a corresponding opening via a tube (5,5'), which can be plugged-in positively on cylinder head side and heat exchanger side. The tube has a plug section at each end, with a radial recess, contain an O-shaped sealing ring (8). The tube is of a metal material, or of plastic. |
