Abstract

A mixer for a vehicle exhaust system includes an outer shell having an inlet end and an outlet end, an upstream baffle positioned adjacent the inlet end to initiate swirling of engine exhaust gases, and a downstream baffle positioned adjacent the outlet end. An impactor extends between the upstream and downstream baffles, and is spaced radially inwardly from an inner surface of the outer shell by a gap.
