| 摘要 |
The invention relates to an exhaust-gas post-treatment arrangement and a method for post-treating exhaust-gases and which is used to remove nitrogen from exhaust gases from an internal combustion engine. Said arrangement comprises two oxidation paths (62, 20, 64; 80, 25, 82) which are selected according to the temperature of the exhaust gas, in order to initially oxidate nitrogen oxides and subsequently to reduce them in order to form nitrogen in a nitrogen removal device. |
