    Abstract: An exhaust system assembly including a catalyst housing, a catalyst core, and a swirler tube positioned inside the catalyst housing. The swirler tube has a plurality of openings that permit radial exhaust flow into an inner volume of the swirler tube from the catalyst housing. One end of the swirler tube has blades that extend inward and include oblique surfaces arranged at oblique angles relative to a centerline axis of the swirler tube. These blades induce a vortex in the exhaust gases exiting the first swirler tube end. The swirler tube is arranged inside the catalyst housing such that a sequential flow path is created where the exhaust gases flowing through the catalyst housing must first pass through the openings in the swirler tube and then by the blades at the first swirler tube end.

    Abstract: An exhaust treatment component for treating an engine exhaust. The component includes a housing including an inlet and an outlet, and a mixing assembly located within the housing between the inlet and the outlet. The mixing assembly includes a decomposition tube having a first end and a second end. The first end is configured to receive the exhaust from the inlet and is configured to receive a reagent exhaust treatment fluid. A flow reversing device is disposed proximate the second end, and the flow reversing device is configured to direct a mixture of the exhaust and reagent exhaust treatment fluid as the mixture exits the second end of the decomposition tube in a direction back toward the first end, wherein the flow reversing device includes a plurality of deflecting members for intermixing the exhaust and reagent exhaust treatment fluid.

    Abstract: An exhaust mixing device for mixing an exhaust produced by an engine with a reagent exhaust treatment fluid that is dosed into the exhaust from a dosing module. The exhaust mixing device includes a decomposition tube having a first end and a second end. The first end of the decomposition tube is configured to receive the exhaust and the reagent exhaust treatment fluid. A flow reversing device is positioned at the second end of the decomposition tube. The flow reversing device includes a plurality of deflecting members that intermix the exhaust and reagent exhaust treatment fluid, and direct the exhaust and reagent exhaust treatment fluid in predetermined directions, wherein the flow reversing device reverses a flow direction of the exhaust back towards the first end of the decomposition tube.
