Abstract: A burner for an exhaust gas treatment system includes a tubular inner housing having a closed upstream end, a reduced diameter portion, and a plurality of apertures downstream of the reduced diameter portion. An outer housing surrounds the inner housing comprising a bypass flow path therebetween. First and second tubular supports fix the upstream end of the inner housing to the outer housing and provide fluid communication between a cavity within the inner housing to a location outside of the outer housing. A plate fixes the downstream end of the inner housing to the outer housing and cooperates with the housings to partially define an aperture formed in a portion of the bypass flow path.

Abstract: An exhaust aftertreatment system may include an injector, an aftertreatment device and a mixer assembly. The injector may be configured to inject a fluid into an exhaust passageway that receives exhaust gas from a combustion engine. The aftertreatment device may be disposed in the exhaust passageway downstream of the injector. The mixer assembly may be disposed in the exhaust passageway upstream of the aftertreatment device and may include a first stage having a plurality of parallel plates and a second stage connected to the first stage and disposed downstream of the first stage. The second stage may include an auger blade. The mixer assembly may divide an exhaust stream into at least two flow paths.
