    Abstract: An exhaust treatment device for treating exhaust includes a main body defining an interior, an inlet, and an outlet; an inlet arrangement disposed at the inlet; an aftertreatment substrate disposed between the inlet and the outlet; a restrictor arrangement disposed between a first closed end of the main body interior and the aftertreatment substrate; and a dosing arrangement configured to inject reactant into the exhaust. The restrictor arrangement defines a restricted passageway that extends towards the first closed end so that exhaust entering the main body interior from the inlet is swirled around the restricted passageway before entering the restricted passageway and passing to a second chamber prior to the aftertreatment substrate.

    Abstract: A dosing and mixing arrangement is disclosed herein. The arrangement includes a mixing tube having a constant diameter along its length. At least a first portion of the mixing tube includes a plurality of apertures. The arrangement also includes a swirl structure for causing exhaust flow to swirl outside of the first portion of the mixing tube in one direction along a flow path that extends at least 270 degrees around a central axis of the mixing tube. The arrangement is configured such that the exhaust enters an interior of the mixing tube through the apertures as the exhaust swirls along the flow path. The exhaust entering the interior of the mixing tube through the apertures has a tangential component that causes the exhaust to swirl around the central axis within the interior of the mixing tube. The arrangement also includes a doser for dispensing a reactant into the interior of the mixing tube.

    Abstract: A method for causing exhaust gas flow to flow at least 270 degrees in a first direction about a perforated tube using a baffle plate having a main body with a plurality of flow-through openings and a plurality of louvers positioned adjacent to the flow-through openings. The method includes deflecting a first portion of the exhaust gas flow with the main body of the baffle plate. The method also includes allowing a second portion of the exhaust gas flow to flow through the flow-through openings of the baffle plate. The method also deflects the second portion of the exhaust gas flow at a downstream side of the main body with the louvers hereby causing the second portion of the exhaust gas flow to flow in the first direction about the perforated tube.
