| 摘要 |
The invention relates to an exhaust gas treatment device for processing exhaust gas from a combustion unit, in particular a diesel engine. Furthermore, the invention relates to a method for processing exhaust gas from a combustion unit by selective catalytic reaction, and to a motor vehicle, in which the method according to the invention is implemented or which includes the exhaust gas treatment device according to the invention. According to the invention, the exhaust gas treatment device comprises an exhaust gas system and an oxidation catalyst, a reduction catalyst for selective catalytic reduction and a particle filter arranged therein, wherein the oxidation catalyst is arranged upstream of the reduction catalyst and the reduction catalyst is arranged upstream of the particle filter. The reduction catalyst (50) is arranged in the exhaust gas system (20) so far upstream in the exhaust gas flow direction (23) that the heat of the exhaust gas passing through the reduction catalyst (50) is sufficient to bring the reduction catalyst (50) to operating temperature. |
