Abstract: A mixer assembly for a vehicle exhaust system includes a housing having an inlet portion and an outlet portion that are connected to each other with a channel portion. An inlet baffle is positioned at the inlet portion and an outlet baffle is positioned at the outlet portion. The inlet and outlet baffles are non-concentric. An injector housing is attached to the housing downstream of the inlet baffle and a spray guide is mounted within the injector housing. The spray guide has a spray inlet and a spray outlet that directs spray into the channel portion.

Abstract: An exhaust system includes an exhaust duct having an internal surface defining an exhaust gas passage extending along an axis. At least one sensor opening is in the exhaust duct and is configured to receive an exhaust gas sensor. A wall is positioned within the exhaust gas passage to extend at least partially around the at least one sensor opening. The wall has an inner wall surface defining an internal volume. An inlet pipe ring is in fluid communication with the internal volume, and the inlet pipe ring extends from a first end open to the internal volume to a second end this is also in fluid communication with the internal volume. The inlet pipe ring includes a plurality of inlet apertures.
