| 摘要 |
The invention relates to an exhaust system (8) of an internal combustion engine (7), comprising, upstream to downstream in the direction of flow of the combustion gases emanating from the engine, an exhaust pipe (11), an oxidation catalyst (12) for the oxidation of the combustion gases, and an SCR catalyst for the selective reduction of the nitrogen oxides (13), characterised in that it comprises, upstream of said oxidation catalyst (12), a device (15) for supplying oxidising gas, connected to said exhaust pipe (11), and a means (16) for regulating the flow of oxidising gas supplied to said exhaust pipe (11). |
