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 cylindrical member surrounds at least a portion of the cone and includes at least one window opening. At least one diverter duct is fixed to the mixer housing and has a first duct end open to the interior cavity and a second duct end at least partially overlapping the at least one window opening such that a portion of the engine exhaust gases in the interior cavity is directed to enter the first duct end, flow through the at least one window and then flow into the cone inlet opening to be mixed with a fluid injected through the doser opening.
