Abstract: 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.

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. The elongate mixing blades are connected together along at least part of their lengths and arranged about the elongate direction, each elongate mixing blade comprising an outer edge extending in the elongate direction. The elongate mixing blades are twisted along their lengths such that the outer edge of each elongate mixing blade is rotated about the elongate direction. The exhaust conduit is configured to locate the first exhaust mixer in an upstream location of the exhaust conduit.

Abstract: 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.

Abstract: A valve suitable for use as an exhaust gas recirculation valve in an engine includes a valve housing defining an interior space, a valve stem and a valve member, which may be a poppet, mounted on said valve stem. The valve member is arranged to move between open and closed positions. The valve further includes a mounting member, which may be a bush, located in the interior space, with said valve stem supported within the mounting member. The valve member includes a deflector to direct fluid away from the mounting member when the valve member is in an open position.

Abstract: A mixing chamber for mixing exhaust gas with intake air, in an engine is provided. The mixing chamber includes a first end, a second end and a side wall. The mixing chamber includes an intake air inlet in fluid communication with the first end of the mixing chamber, an exhaust gas inlet arranged in the side wall of the mixing chamber, located downstream of the intake air inlet and having a leading flow edge corresponding to an intersection of the intake air inlet and the exhaust gas inlet, and a mixing projection located on an inner periphery of the side wall. The mixing projection extends at least partially across the mixing chamber, wherein the mixing projection has a deflection surface and a trailing edge which is at least partially aligned with the leading flow edge of the exhaust gas inlet.
