Abstract

An aftertreatment component's shape, entrance geometry, and/or position within an aftertreatment assembly can be modified for local and/or bulk exhaust flow control. In some implementations, a body of the aftertreatment component has a non-circular cross-section, a non-circular opening, and/or a variable face geometry. The non-circular cross-section and/or opening can be of a variety of different shapes.
