Abstract: A flow hood assembly for an engine aftertreatment system having a particulate filter and a selective catalytic reduction device is disclosed. An outer case defines a cavity, the outer case having an inlet and an outlet formed therein, and a neck section formed between the inlet and the outlet. A socket in the outer case is in an opposed relationship to the outlet and is shaped to receive an injector that introduces a reducing agent into the flow of exhaust gases. A baffle reduces a cross-sectional area of the cavity at the neck section to increase exhaust gas velocity at a sensor positioned at the neck section. A deflector member in the cavity between the baffle and the socket directs a portion of the exhaust gases towards the socket and across the injector nozzle.

Abstract: 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.

Abstract: An injector mount for mounting an injector adjacent a curved fluid flow path includes an inner surface defining a boundary of the curved fluid flow path and an aperture between the inner surface and an outer surface. The aperture is configured to receive an injector. The inner surface includes a peripheral region, a central region recessed relative to the peripheral region, and an intermediate region including a convex surface that joins an inner edge of the peripheral region to an outer edge of the central region.
