| description | An inlet assembly 410 for a housing 201 containing an aftertreatment component 250 of an aftertreatment system 400 comprises an inlet conduit 412 configured to be disposed substantially perpendicular to a longitudinal axis of the housing. A flow redirection conduit 413 is disposed downstream of the inlet conduit and is coupled to the end of the housing. A flow distribution plate 420 with slots 422 (which may be perpendicular to the housing) is disposed in the inlet assembly inclined to a longitudinal axis of the housing. In some embodiments, an upstream portion of the plate 420 is disposed in the inlet conduit 412, and a downstream portion of the plate 420 is disposed in the flow redirection conduit. The plate may comprise vanes 423. Alternatively, the redirecting conduit comprises a plurality of protrusions (fig.2, 215) project from a sidewall of the conduit towards an inlet face of the aftertreatment component and are configured to provide a uniform exhaust gas flow to the inlet face. |
