    摘要: A mixing apparatus mountable within a generally cylindrical passage defined by an exhaust gas conduit of an exhaust gas after-treatment system is provided. The passage includes an outer region and an inner region operable to convey an exhaust stream and a liquid stream, such as a urea stream. The mixing apparatus includes a retainer ring operable to retain the mixing apparatus within the passage. A first plurality of fins extends from the retainer ring and is operable to impart a rotational velocity component in a first direction to the exhaust stream and urea stream in the outer region of the passage. A second plurality of fins extends from the retainer ring and is operable to impart a rotational velocity component in a second direction, opposite the first direction, to the exhaust stream and urea stream in the inner region of the passage.
