Abstract
A mixer for a vehicle exhaust system includes a mixer body defining a mixer central axis and having an inlet configured to receive engine exhaust gas and an outlet. The mixer further includes an upstream baffle positioned within the mixer body and a downstream baffle positioned within the mixer body to be spaced from the upstream baffle in a direction along the mixer central axis. A doser defines a doser axis and is positioned to spray a reducing agent into an area between the upstream baffle and the downstream baffle such that a mixture of reducing agent and exhaust gas exits the outlet. The mixture moves through a rotational flow path that is at least 360 degrees before exiting the outlet.
