SYSTEMS AND METHODS FOR PROVIDING UNIFORM EXHAUST GAS FLOW TO AN AFTERTREATMENT COMPONENT

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. 一种用于壳体的入口组件，该壳体包含后处理系统的后处理部件，入口组件包括入口导管，该入口导管被配置成基本上垂直于壳体的纵向轴线设置。流改向导管被设置在入口导管的下游，并且联接到壳体的端部。多个突出部从流改向导管的侧壁朝向后处理部件的入口面突出，并且被配置成向入口面提供均匀废气流。可选地，流分配板被设置在流改向导管中，
