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.

Decomposition chambers for aftertreatment systems

A decomposition chamber for an exhaust aftertreatment system includes an inlet conduit centered on an inlet conduit axis and configured to receive exhaust, a decomposition conduit coupled to the inlet conduit, an endcap coupled to the decomposition conduit, and an injector coupled to the endcap and configured to provide reductant into the decomposition conduit along an injection axis. The decomposition chamber includes a guide swirl mixer coupled to at least one of the inlet conduit or the endcap. The guide swirl mixer includes a first portion disposed within the inlet conduit, and a second portion disposed within the decomposition conduit such that the inlet conduit axis extends through the second portion. The second portion extends at least partially around the injection axis.
