EXHAUST GAS POST TREATMENT UNIT OF AN INTERNAL COMBUSTION ENGINE AND VEHICLE COMPRISING SUCH UNIT

摘要

The invention relates to an assembly for post-treating the exhaust gases of a supercharged combustion engine via a turbocharger comprising, in the direction of flow of the exhaust gases of the engine: a turbocharger (3); an oxidation catalyst (4); a catalyst for the selective catalytic reduction of nitrogen oxides (5); and a particle filter (6), characterized in that the assembly is arranged according to a substantially U-shaped architecture, comprising: a first straight branch (1) comprising the turbocharger (3) and the oxidation catalyst (4); a second straight branch (2) comprising the catalyst for the selective catalytic reduction of nitrogen oxides (5) and the particle filter (6); and a fluid connection (8) between the first and second branches (1, 2).
