Abstract

An assembly (10) for introducing a reducing agent into the exhaust pipe (12) of an exhaust system of an internal combustion engine, in particular of a motor vehicle, has a feed connector (14) which opens into the exhaust pipe (12) and includes a wall (16), a feed device (20) for reducing agents which opens into the feed connector (14), and a device (22) for generating a gas flow (G) which is additional to the reducing agent flow (R) and lines the wall (16) of the feed 10 connector (14). Furthermore, there is described a method of introducing a reducing agent into the exhaust pipe (12) of an exhaust system of an internal combustion engine, in particular of a motor vehicle.
