Abstract: A system for removing residual reductant from at least one component of a reductant dosing system associated with an aftertreatment system includes a first container disposed in fluid communication with the reductant dosing system. The system also includes a first conduit for providing fluid communication between the first container and the reductant dosing system. Based on a generation of a vacuum within the first container, the first conduit is operative to remove the residual reductant from the at least one component of the reductant dosing system and introduce the residual reductant into the first container.

Abstract: A panel assembly includes a panel member having a mounting side and at least one elongated member. The at least one elongated member includes a mounting edge, a second edge opposite the mounting edge of the at least one elongated member, and a plurality of first spaced apart openings. The panel assembly further includes at least one elongated intersecting member. The at least one elongated intersecting member includes a mounting edge, a second edge opposite the mounting edge of the at least one elongated intersecting member, and a plurality of second spaced apart openings. Further, one of the at least one elongated member and the at least one elongated intersecting member includes at least one slot, the at least one elongated member and the at least one elongated intersecting member intersecting at the at least one slot.

Abstract: An aftertreatment module for use with an engine is disclosed. The aftertreatment module may include a housing having an inlet configured to direct exhaust in a first flow direction into the aftertreatment module, and an outlet configured to direct exhaust in the first flow direction out of the aftertreatment module. The aftertreatment module may also include a catalyst bank separating the inlet from the outlet. The catalyst bank may have a face disposed at an oblique angle with respect to the first flow direction. The oblique angle may create an inlet passage extending from the inlet to the catalyst bank and having a decreasing cross-sectional area, and an outlet passage extending from the catalyst bank to the outlet and having an increasing cross-sectional area.
