Abstract: A mixer includes a baffle having a baffle inlet receiving exhaust gas from an upstream exhaust component and a baffle outlet directing exhaust gas to a downstream exhaust component. A cover provides a chamber between an internal surface of the cover and the baffle. An internal box is positioned within the chamber to cover the baffle outlet and includes a bottom wall with a peripheral wall extending about at least a portion of an outer periphery of the bottom wall. At least one deflector wall is positioned within the internal box to provide a wall surface that is spaced from the peripheral wall to define an internal flow path that diverts exhaust gas at least partially around the baffle outlet before exiting the baffle outlet. An opening is located in the peripheral wall to receive exhaust gas exiting the inlet and to direct exhaust gas into the internal flow path.

Abstract: An injection and mixing device comprises a casing having an exhaust inlet and an exhaust outlet, the casing internally defining a passage for exhaust gases from the exhaust inlet to the exhaust outlet. The exhaust inlet opens into an inlet region of the passage. The injection and mixing device further includes an injector of a liquid comprising a nitrogen oxide reducing agent or a precursor of such a reducing agent. A deflector is housed within the casing and defines in the passage a first passage connecting the inlet region to the exhaust outlet, in which the exhaust gases flow at a first average velocity, and a second passage connecting the inlet region to the exhaust outlet, in which the exhaust gases flow at a second average velocity lower than the first average velocity, The injector injects liquid into the second passage.
