Abstract
An exhaust gas aftertreatment device for a motor vehicle has an exhaust pipe and a mixing chamber arranged in the exhaust pipe to mix an exhaust gas stream with a reducing agent which can be introduced into the mixing chamber by a dosing device. The mixing chamber has a wall which is on the input side as viewed in a main flow direction of the exhaust gas stream through the exhaust pipe and in which a first inlet for the exhaust gas is formed. The first inlet extends in some regions in a lateral surface region of the input-side wall such that exhaust gas entering the mixing chamber through the first inlet can be set in a rotating motion inside the mixing chamber. The dosing device has an outlet device where a longitudinal axis of the outlet device is inclined towards the main flow direction of the exhaust gas stream.
