EXHAUST-GAS TREATMENT DEVICE

摘要

An exhaust gas treatment device includes an exhaust gas treatment component for conducting a flow in a flow direction from an inflow side to an outflow side. A metering device for metering reducing agent into the exhaust gas treatment device is disposed downstream of the outflow side in the flow direction. The metering device has a metering direction which runs at least partially counter to the flow direction. The outflow side of the exhaust-gas treatment component is spanned at least partially by a porous layer and there is a spacing between the metering device and the exhaust-gas treatment component selected in such a way that injected reducing agent reaches the porous layer. A motor vehicle having the device is also provided.
