Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.

Abstract: A mixing system for an exhaust aftertreatment system includes a first mixing device having a plurality of first auger blades and an inlet having a first cross-sectional area. A second mixing device is separate and downstream from the first mixing device and includes a second auger blade. The second mixing device includes an inlet having a second cross-sectional area greater than the first cross-sectional area. A plurality of flow paths created by the first mixing device are recombined into a single flow path between the first and second mixing devices. A longitudinal center line of the first mixing device is offset from a longitudinal center line of the second mixing device.

Abstract: A mixing system for an exhaust system includes a first mixing device having a plurality of first auger blades and an inlet having a first cross-sectional area. A second mixing device is separate and downstream from the first mixing device and includes a second auger blade. The second mixing device includes an inlet having a second cross-sectional area greater than the first cross-sectional area. A flow path longitudinal centerline of the first mixing device extends at an angle to a flow path longitudinal centerline of the second mixing device. A flow path longitudinal centerline of the first mixing device intersects the second auger blade. The first mixing device is disposed within a first portion of an exhaust pipe and the second mixing device is disposed in a second portion of the exhaust pipe. The second portion has a larger cross-sectional area than the first portion.

Abstract: A mixer assembly for treating exhaust with an injected reductant as the exhaust flows through an exhaust gas passageway includes a tubular shell and a rod. A first end and a second opposite end of the rod are fixed to the shell. The rod has a serpentine shape with a plurality of parallel extending portions interconnected by curved portions. The curved portions are positioned proximate an inner surface of the shell such that the rod traverses the exhaust passageway. The mixer assembly is positioned such that the rod is directly impinged by reductant injected into the exhaust gas passageway.

Abstract: A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine comprises a mixer housing including a wall defining an exhaust passageway having a longitudinal axis. A tubular swirling device housing extends along a first axis substantially transverse to the longitudinal axis. The tubular swirling device includes a plurality of openings through which exhaust gas enters. The exhaust gas within the tubular swirling device swirls about the first axis and exits at an outlet end of the tubular swirling device. A mixing plate is positioned immediately downstream of the tubular swirling device and includes apertures through which the exhaust gas exiting the outlet end of the tubular swirling device flows. The mixing plate swirls the exhaust about a second axis extending parallel to the longitudinal axis.
