Abstract

A mixer for a vehicle exhaust system includes a mixer housing that defines an interior cavity for engine exhaust gases, and which includes a doser opening formed within a wall of the mixer housing. A cone has a cone inlet opening aligned with the doser opening and a cone outlet into the interior cavity. A diverter has at least one first opening that is open to the interior cavity and a second opening that surrounds the cone outlet. Exhaust flow is directed by the diverter to the cone inlet opening to be mixed with a fluid injected through the doser opening.
