摘要： 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.
