Abstract
An exhaust gas aftertreatment system includes an exhaust gas conduit a mixer, and a plurality of flow disrupters. The exhaust gas conduit is centered on a conduit center axis and includes an inner surface. The mixer includes a mixer body and an upstream vane plate. The upstream vane plate has a plurality of upstream vanes. At least one of the upstream vanes is coupled to the mixer body. The flow disrupters are disposed downstream of the mixer and circumferentially around the conduit center axis. Each of the flow disrupters is coupled to the exhaust gas conduit or integrally formed with the exhaust gas conduit. Each of the flow disrupters extends inwardly from the inner surface.
