Abstract (en)

[origin: WO2006100090A1] The invention relates to an exhaust system (1) on an internal combustion engine (2), comprising an inlet system (3) and an exhaust outlet (4), whereby the exhaust outlet (4) and the inlet system (3) are connected by means of an exhaust recycle line (5) in which an exhaust treatment unit (6) and a heat exchanger (7) are embodied. The heat exchanger (7) has a first back pressure and the exhaust treatment unit (6) has a second back pressure, smaller than the first back pressure, characterised in that the exhaust treatment unit (6) is embodied at such a first separation (8) from the heat exchanger (7) in the direction of flow that, during operation, a gas flow (14) entering the exhaust treatment unit (6) is equilibrated. Said exhaust system permits an advantageous embodiment of a heat exchanger (7) and an exhaust treatment unit (6), such as for example a honeycomb body in the exhaust recycle line (5), whereby both the heat exchanger (7) and the exhaust treatment unit (6) can have a smaller embodiment than in conventional systems. The above reduces the costs considerably on equipping such a system.
