International Classification:

F01N 3/28

Abstract:

A flow mixing device includes a body having a first end, a second end, and an interior volume defined between them. An inlet plate, coupled to the first end of the body, defines at least two inlet orifices in fluid communication with the interior volume. Similarly, an outlet plate, coupled to the second end defines an outlet passage of the flow mixing device. A diffuser conduit, coupled to the inlet plate, defines an inlet passage disposed in fluid communication with the respective inlet orifices. A separator plate assembly disposed in the interior volume extends partially between the first and second ends of the body. Flow guiding vanes, coupled proximal to the second end, extend partially within the diffuser conduit.

Abstract:

An exhaust gas aftertreatment system includes an exhaust conduit having an inner wall, and a mixer mounted inside the exhaust conduit. The exhaust conduit defines a passage along a length of the exhaust conduit for exhaust gas flow therethrough. The mixer includes first bars coupled to second bars. Each first bar includes deflectors on a straight section, a first end, and a second end. The one or more of the first bars include a curved section at the first end and the second end. Each second bar includes a straight section, a third end, and a fourth end. The one or more of the second bars include a curved section at the third end and the fourth end. The mixer is mounted inside the exhaust conduit by coupling the curved section of the first bar and the second bar to the inner wall of the exhaust conduit.

Abstract:

A spreader bar assembly is provided. The spreader bar assembly includes a pair of arms disposed in a scissor type arrangement. The pair of arms defines an axis of rotation therebetween. The spreader bar assembly further includes a contact member attached to an end of each of the pair of arms. The contact member of the spreader assembly is configured to contact with a catalyst. The spreader assembly also includes a sealing member. The sealing member is provided in association with the contact member. The sealing member is disposed on a first side of each of the pair of arms such that on exerting a force on the sealing member on the first side of each of the pair of arms, an opposing force is generated on a second side of each of the pair of arms disposed substantially opposite the first side of each of the pair of arms.
