Beschreibung
Zusammenfassung:	Arrangement (1) to introduce a liquid medium, for example urea, into exhausts from a combustion engine, which arrangement comprises: - a mixing chamber (2) intended to be perfused by exhausts, wherein the mixing chamber is delimited in a radial direction outwards by a tubular metal wall (6), and - an injection element (10) for injection of the liquid medium as a spray (11) into the mixing chamber. Said tubular wall has a variable wall thickness seen in the mixing chamber's longitudinal direction, so that the section (6a) of the tubular wall which is intended to be impacted by said spray of a liquid medium from the injection element has a wall thickness which is greater than the wall thickness of those sections (6b) of the tubular wall l which are adjacent to this wall section.
