A mixer for an emissions cleaning module is provided. The mixer having an elongate body configured for location within a flowhood and a downstream conduit of an emissions cleaning module. A plurality of apertures are included in the mixer and configured to permit passage of exhaust gas therethrough, to promote mixing, in use of an injected additive and a flow of exhaust gas. An emissions cleaning module including such a mixer is also described.

Mixer and emissions cleaning module

An emissions cleaning module including a heat shield that comprises a first section and a second section that are coupled together around a flowhood. The heat shield substantially fully envelops all external surfaces of the flowhood.

Heat shield and emissions cleaning module

A flowhood is provided to which an upstream conduit and a downstream conduit of an emissions cleaning module can be connected includes a first section and a second section. The second section includes a first aperture for connection to the upstream conduit and a second aperture for connection to the downstream conduit. The first and second apertures may face substantially in the same direction to permit a compact arrangement. A body of the first section may be shaped to channel gas flow from the first aperture to the second aperture. An emissions cleaning module including such a flowhood is also described.
