Abstract
A decomposition chamber for an aftertreatment system includes an outer conduit that has an inner surface, a doser mount coupled to the outer conduit, and an inner conduit disposed within the outer conduit. The inner conduit has an upstream end, a downstream end, and an outer surface that is spaced from the inner surface of the outer conduit. The inner conduit includes an opening aligned with the doser mount and disposed closer to the upstream end than to the downstream end, and a lip extending along a portion of the opening and angled partially outward and partially toward the upstream end.
