An exhaust mixer apparatus, emissions cleaning module, and a method of manufacturing the exhaust mixer apparatus is provided. The exhaust mixer apparatus comprises an exhaust conduit, a first exhaust mixer and a second exhaust mixer. The exhaust conduit is configured to extend in an elongate direction comprising an inlet and an outlet for transporting exhaust fluid. The first exhaust mixer comprises a plurality of elongate mixing blades each having a length extending in the elongate direction. Each elongate mixing blade comprising an outer edge extending in the elongate direction and blades are twisted along their lengths such that the outer edge is rotated about the elongate direction. The second exhaust mixer is configured to impart a swirl on an exhaust fluid and spaced apart from the first exhaust mixer in the exhaust conduit.

Exhaust mixer, emissions cleaning module and method of manufacture

The present disclosure relates to a mixing chamber for mixing exhaust gas with intake air in an engine. The mixing chamber has an intake air inlet, an exhaust gas inlet and a mixing post. The mixing post is located downstream of the charge air inlet and upstream of a point where the flow of exhaust gas meets the flow of intake air, the mixing post extending across the mixing chamber. The mixing post has a longitudinal axis which is oriented perpendicular to a longitudinal axis of the mixing chamber.
