Abstract (en)
[origin: WO2018188968A1] The invention relates to an exhaust gas system (1) for the post-treatment of exhaust gases of an internal combustion engine, comprising: a catalyst (3) for the oxidation of the exhaust gas and/or a catalyst for storing nitrogen oxides, arranged behind one another in the flow direction (2) of the exhaust gas; an inlet point (4) for supplying a reducing agent; an SCR catalyst (6) for the selective catalytic reduction of nitrogen oxides; and a particle filter, wherein the particle filter (7) is arranged behind the SCR catalyst (6) in the flow direction (2), and a second SCR catalyst (8) and/or an ammonia slip catalyst is arranged behind the particle filter (7) in the flow direction (2).
