Abstract: An exhaust treatment component including a mixing assembly located within a housing. The mixing assembly includes a decomposition tube having a first end and a second end, the first end being configured to receive the exhaust from the inlet and being configured to receive a reagent exhaust treatment fluid; a flow reversing device disposed proximate the second end, the flow reversing device 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, the flow reversing device including a plurality of deflecting members for swirling and intermixing the exhaust and reagent exhaust treatment fluid; and a swirl arrester device configured to eliminate the swirling of the exhaust and reagent exhaust treatment fluid after exiting the flow reversing device.

Abstract: An aftertreatment system may include an exhaust gas passageway and a mixer assembly. The exhaust gas passageway may receive exhaust gas from an engine. The mixer assembly is disposed within the exhaust gas passageway and may include an upstream baffle, a downstream baffle, and a tube extending between and connected to the upstream and downstream baffles. The tube may include an inner surface defining a first flow path through the mixer assembly. The upstream and downstream baffles may be attached to each other, the tube and the exhaust gas passageway. The upstream and downstream baffles may cooperate to define a second flow path through the mixer assembly. The second flow path may extend in a rotational direction around an outer surface of the tube.
