  • SCR EXHAUST-GAS AFTERTREATMENT DEVICE AND MOTOR VEHICLE WITH SUCH AN SCR EXHAUST-GAS AFTERTREATMENT DEVICE
    Publication number: 20150252706
    Abstract: An exhaust-gas aftertreatment device for an aftertreatment of the exhaust-gas of an internal combustion engine includes an SCR catalytic converter and an SCR particulate filter downstream of the SCR catalytic converter. The SCR catalytic converter has an SCR catalytic coating for a selective reduction of nitrogen oxides in the presence of a reducing agent added to the exhaust-gas in a metered manner. The SCR catalytic converter has a flow-through substrate. The SCR catalytic coating of the SCR catalytic converter is disposed on the flow-through substrate. The SCR particulate filter has an SCR catalytic coating for a selective reduction of nitrogen oxides in the presence of the reducing agent added to the exhaust-gas in a metered manner. The SCR particulate filter has a particulate filter substrate. The SCR catalytic coating of the SCR particulate filter is disposed on the particulate filter substrate.
