ABSTRACT:
A device is provided for admixing a reducing agent into an exhaust gas flow of an internal combustion engine having an exhaust system and a dosing device for feeding the reducing agent into the exhaust system. At least one heating rib, heatable by the exhaust gas and arranged downstream from the dosing device in the exhaust system is oriented largely in a flow direction of the exhaust gas. The dosing device is situated in or on a hollow body arranged on the exhaust system, an internal volume of which is connected to the exhaust system to conduct exhaust gas. An extremely low-flow device for admixing a reducing agent into an exhaust gas flow of an internal combustion engine is achieved by this design.
