housing which has an intake trumpet on the intake end and an exhaust pipe on the outputend. Catalytic converter elements are arranged in the housing with one inlet end in aninlet chamber and with an outlet end in an outlet chamber. An outlet end of the intaketrumpet communicates with the inlet chamber. To improve the efficiency of the SCRcatalytic converter the inlet chamber is sealed off from the outside and with respect tothe intake trumpet and the catalytic converter elements to the extent that in operationof the internal combustion engine with exhaust gas loaded with urea, passing through theintake trumpet into the inlet chamber, the exhaust gas leaves the inlet chamber onlythrough the catalytic converter elements.
