Device for the aftertreatment of exhaust gases of internal combustion engines |
摘要 |
A device for the aftertreatment of exhaust gases in an exhaust gas system of internal combustion engines, having at least one reductant decomposition catalyst. Arranged in the exhaust gas flow, and a metering device arranged upstream of the latter in an exhaust gas line for supplying reductant. Preferably at least one other catalyst device is provided downstream of the reductant decomposition catalyst. An inlet section for the exhaust gas having at least one flow deflection area is arranged upstream of the reductant decomposition catalyst and constructed for the exhaust gas to be fed into a housing radially outside an inlet pipe adjoining the reductant decomposition catalyst that encloses the inlet pipe, and is guided in counterflow through a front inlet opening of the inlet pipe to the reductant decomposition catalyst. The reductant is fed into the flow deflection area associated with the inlet opening. |
