摘要: A SCR catalyst system, comprising a first SCR catalyst (1) and a second SCR catalyst (2) which is disposed in the exhaust gas tract downstream of the first SCR catalyst (1). At least one metering device (12) for metering in a reducing agent solution is disposed in the exhaust gas tract upstream of a first SCR catalysis element (13) of said first SCR catalyst (1). The SCR catalyst system does not require a device for metering a reducing agent solution into a second SCR catalysis element (21) of the second SCR catalyst (2).
