Abstract

The invention relates to an exhaust gas after-treatment device for an internal combustion engine, including a housing into which an exhaust pipe that opens into a mixing chamber penetrates. The mixing chamber is shaped as a pot and reverses a direction of flow of the incoming exhaust gas whereby it returns the exhaust gas radially outside of the exhaust pipe. An open end of the pot-shaped mixing chamber opens into a collecting space which is designed so that it supplies the exhaust gas to at least one downstream SCR catalytic converter.
