Abstract
A mixing conduit for use within an exhaust treatment system of a work vehicle. The mixing conduit is configured to receive engine exhaust and a mixture of engine exhaust and reductant. The mixing conduit includes an outer tube and an inner tube within the outer tube. Each tube extends lengthwise from upstream ends to downstream ends of the inner and outer tubes, respectively. The inner tube includes an exterior surface, and the outer tube includes an interior surface. The inner tube defines an inner flowpath within the inner tube. The outer tube and inner tube also define an outer flowpath radially between the exterior surface of the inner tube and the interior surface of the outer tube. The mixing conduit further includes one or more swirler vanes extending radially between the exterior surface of the inner tube and the interior surface of the outer tube and within the outer flowpath.
