Beschreibung
Zusammenfassung:	A mixer assembly for mixing an injected reductant with an exhaust gas comprises a tubular housing including a reductant inlet, an exhaust gas inlet and an exhaust gas outlet. The reductant inlet is positioned on a first side of the tubular housing and oriented to direct injected reductant along an injection access that extends transversely to a longitudinal axis. A first flow guide element is shaped as a sheet including a first aperture extending therethrough as well as a surface facing upstream. Exhaust gas flowing through the first aperture is impinged by the injected redundant. A second flow guide element is shaped as a sheet, positioned downstream from the first flow guide element and fixed to the first flow guide element to define a mixing chamber between the first flow guide element and the second flow guide element in which the injected redundant and the exhaust gas mix.
