Abstract
A mixer for a vehicle exhaust system includes a mixer housing defining a mixer central axis and having an inlet at an upstream end and an outlet at a downstream end. An upstream baffle is in the housing at the upstream end and includes at least one inlet opening configured to receive engine exhaust gas. A downstream baffle is in the mixer housing at the downstream end such that the downstream baffle is axially spaced from the upstream baffle. The downstream baffle includes at least one outlet opening. A housing opening is formed within the mixer housing at a location between the upstream and downstream baffles, and which is configured to receive a doser. A cone has a cone outlet opening aligned with the housing opening, and an extension portion extends outwardly from a wide end of the cone to provide a wall that surrounds the cone outlet opening.
