Abstract: An exhaust aftertreatment system may include an exhaust gas passageway and a mixer assembly. The exhaust gas passageway may receive exhaust gas output from a combustion engine. The mixer assembly may be disposed along the exhaust gas passageway and may receive the exhaust gas. The mixer assembly may include a mixer housing, a mixing bowl and an injector housing. The mixing bowl may be disposed within the mixer housing and may include an outer diametrical surface that engages an inner diametrical surface of a wall of the mixer housing. The injector housing may extend through the wall and into an aperture in the mixing bowl. The aperture may define a flow path through which at least a majority of the exhaust gas entering the mixer assembly flows. The mixing bowl may include an upstream end portion having contours directing the exhaust gas toward the injector housing.

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.

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: An exhaust aftertreatment system may include a reductant tank, a gaseous ammonia source, an injector, first conduit and a second conduit. The injector may receive the liquid reductant from the reductant tank and the gaseous ammonia from the gaseous ammonia source and inject the liquid reductant into a stream of exhaust gas in a first mode, inject the gaseous ammonia into the stream of exhaust gas in a second mode, and both the liquid reductant and the gaseous ammonia into the stream of exhaust gas in a third mode. The first conduit may communicate liquid reductant from the reductant tank to the injector. The second conduit may communicate gaseous ammonia from the gaseous ammonia source to the injector.
