An exhaust treatment system includes an exhaust conduit for conveying exhaust gases from an engine of a vehicle. An aftertreatment device is disposed in the exhaust conduit. A flow device is disposed upstream of the aftertreatment device. The flow device includes a base having a first surface and an oppositely disposed second surface. The base defines a plurality of openings. A plurality of flow deflectors is engaged to the base at the plurality of openings. Each flow deflector includes a first deflector that extends outwardly from the first surface of the base and a second deflector that extends outwardly from the second surface of the base. The first and second deflectors define a passage. Flow of exhaust gases through the passage cause exhaust gases to swirl about a longitudinal axis of the exhaust conduit.

The present disclosure relates to a device for mounting an injector to an exhaust pipe. The device includes an injector mounting structure having an exterior surface configured for mounting the injector. The injector mounting structure also includes an interior surface arrangement defining an interior volume and a port for allowing the injector to inject a reductant into the interior volume. The interior surface arrangement is configured to prevent swirling of exhaust within the interior volume.
