Abstract
An exhaust gas treatment arrangement for an exhaust gas system of an internal combustion engine includes a first exhaust gas flow path leading from an exhaust gas inlet provided on a housing to an exhaust gas outlet provided on the housing and a second exhaust gas flow path leading from the exhaust gas inlet to the exhaust gas outlet. The second exhaust gas flow path is separate from the first exhaust gas flow path. A flow path switching unit changes the exhaust gas stream parts, which are conducted in the first exhaust gas flow path and the second exhaust gas flow path. A reactant supply device supplies reactant into the second exhaust gas flow path downstream of the exhaust gas inlet and an SCR catalyst arrangement is provided in the second exhaust gas flow path upstream of the exhaust gas outlet.
