Abstract
A mixing system for an exhaust system includes a first mixing device having a plurality of first auger blades and an inlet having a first cross-sectional area. A second mixing device is separate and downstream from the first mixing device and includes a second auger blade. The second mixing device includes an inlet having a second cross-sectional area greater than the first cross-sectional area. A flow path longitudinal centerline of the first mixing device extends at an angle to a flow path longitudinal centerline of the second mixing device. A flow path longitudinal centerline of the first mixing device intersects the second auger blade. The first mixing device is disposed within a first portion of an exhaust pipe and the second mixing device is disposed in a second portion of the exhaust pipe. The second portion has a larger cross-sectional area than the first portion.
