Abstract
An inlet assembly for a housing containing an aftertreatment component of an aftertreatment system comprises an inlet conduit configured to be disposed substantially perpendicular to a longitudinal axis of the housing. A flow redirection conduit is disposed downstream of the inlet conduit and is coupled to the end of the housing. A plurality of protrusions project from a sidewall of the flow redirection conduit towards an inlet face of the aftertreatment component and are configured to provide a uniform exhaust gas flow to the inlet face. Alternatively, a flow distribution plate having a plurality of slots defined substantially perpendicular to the longitudinal axis is disposed in the flow redirection conduit, the plate being inclined with respect to the longitudinal axis. The slots are configured to provide a uniform exhaust gas flow to the inlet face.
