Abstract: A flow device for an exhaust system includes a body that defines an interior cavity. An exhaust inlet passage is disposed in the interior cavity. An exhaust outlet passage is disposed in the interior cavity so that at least a portion of the exhaust inlet passage circumferentially surrounds at least a portion of the exhaust outlet passage. A doser is adapted to inject reductants into the interior cavity of the body such that the reductants are injected in the same general direction as the direction of flow of the exhaust gases.

Abstract: A dosing and mixing assembly for an exhaust aftertreatment device includes a conduit arrangement defining overlapping, coaxial flow paths that join at a common flow path. The conduit arrangement defines a mixing region upstream of the overlapping, coaxial flow paths, an impact region at the overlapping, coaxial flow paths, and a merge region where the coaxial flow paths join. The outer of the coaxial flow paths insulates the inner of the flow paths at least as the impact region. Reactant can be dispensed into the inner flow path along a spray path that intersects the impact region of the conduit arrangement. A spray protector can be provided at or upstream of the mixer to inhibit swirling of reactant at the doser nozzle.

Abstract: The invention pertains to a spray/gas mixer, comprising: a main body having a circumferential wall with a first longitudinal axis (A) and extending from a first end to a second end, the first end defining an inlet opening, the second end defining an outlet opening; a divider baffle inside the interior; a swirl duct within the interior along a second longitudinal axis (B), having one end adjacent to the wall and a second end extending to the divider baffle; an injector orifice at the first end of the swirl duct; a swirl promoting means; and a restrictor arrangement. The swirl promoting means is arranged between the divider baffle and the restrictor arrangement, such that gas passing through the swirl promoting means is swirled around the first longitudinal axis (A) before passing through the restrictor. The restrictor arrangement is disposed between the swirl promoting means and the second end, forcing gas reaching it from an upstream side away from a peripheral region of the interior towards a center axis of the main body.

Abstract: A mixing device includes a mixing cavity having a partially open wall and a closed wall. In certain examples, the partially open wall and the closed wall are two separately formed pieces. A downstream side of the mixing device is shaped so as to define a helicoidal groove for circumferentially guiding gas from an outlet opening of the mixing cavity in a downstream direction. An injector sprays reactant into the mixing cavity.

The swirl promoting means is arranged between the divider baffle and the restrictor.
