A mixer (48) is carried in the mixer housing. A reactant release device (56) at the mixer housing releases reactant into a reactant-receiving duct (72) of the mixer. The mixer housing includes a first housing part (36) forming the upstream connection area (24) and a second housing part (38) forming the downstream connection area together with the first housing part.

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

A hydrogen molecule remixing device includes a base, a first gas and water channelling disc, an anode, a cathode, an ion membrane, a second gas and water channelling disc, a cover, a cationic water outlet connector and a connector. In practice, the source water is electrolyzed in the anode cavities of the anode to form oxygen molecules, ozone and anionic water, and electrolyzed in the cathode cavities of the cathode to form hydrogen molecules and cationic water. The hydrogen molecules are carried by the cationic water into the collecting and guiding chambers of the second gas and water channelling disc, so that the hydrogen molecules and the cationic water produce a blending reaction, and more hydrogen molecules are dissolved into the cationic water.

A mixing assembly for an exhaust aftertreatment system includes a mixing body, an upstream plate, a downstream plate, and a swirl plate. The mixing body includes an upstream mixing body opening and a downstream mixing body opening. The upstream mixing body opening is configured to receive exhaust gas. The upstream plate is coupled to the mixing body. The upstream plate includes a plurality of upstream plate openings. Each of the plurality of upstream plate openings is configured to receive a flow percentage that is less than 50% of the total flow of the exhaust gas. The downstream plate is coupled to the mixing body downstream from the upstream plate in a direction of exhaust gas flow. The downstream plate includes a downstream plate opening. The swirl plate is positioned between the upstream plate and the downstream plate and defines a swirl collection region and a swirl concentration region.

An exhaust system for an internal combustion engine includes an oxidation catalytic converter unit (12) with a first catalytic converter housing with a first housing axis (A.sub.1). An SCR catalytic converter unit (18) has a second catalytic converter housing (20), with a second housing axis (A.sub.2). A mixer housing (16) has an upstream connection area (24) adjoining a downstream end (26) of the first catalytic converter housing (14) and has a downstream connection area (28) adjoining an upstream end (30) of the second catalytic converter housing. A mixer (48) is carried in the mixer housing. A reactant release device (56) at the mixer housing releases reactant into a reactant-receiving duct (72) of the mixer. The mixer housing includes a first housing part (36) forming the upstream connection area (24) and a second housing part (38) forming the downstream connection area together with the first housing part.

A fluid distributor comprises a first conduit extending along a first elongated axis and a second conduit circumscribing the first conduit. A first area comprises a cross-sectional flow area of the first conduit taken perpendicular to the first elongated axis. The first conduit comprises a first plurality of orifices comprising a first combined cross-sectional area. The second conduit comprises a second plurality of orifices comprising a second combined cross-sectional area. A first ratio of the first area to the first combined cross-sectional area can be about 2 or more. A second ratio of the first combined cross-sectional area to the second combined cross-sectional area can be about 2 or more. An angle between a direction of an orifice axis of a first orifice of the first plurality of orifices and a direction of an orifice axis of a first orifice of the second plurality of orifices can be from about 45 to 180.

An aftertreatment system includes a filter configured to receive an exhaust gas and a selective catalytic reduction (SCR) system configured to treat the exhaust gas. A body mixer is disposed downstream of the filter and upstream of the SCR system. The body mixer includes a housing defining an internal volume and including at least a first passageway, a second passageway, and a third passageway. The first passageway receives a flow of the exhaust gas from the filter and directs the flow of the exhaust gas towards the second passageway. The second passageway redirects the flow in a second direction opposite the first direction towards the third passageway. The third passageway redirects the flow in a third direction opposite the second direction towards the SCR system. An injection port is disposed on a sidewall of the housing and configured to communicate an exhaust reductant into the internal volume.

The drinking glass as disclosed herein may include a beverage container having a lower base and an upwardly extending outer sidewall terminating in an upper rim having an open mouth of a size and shape for select pour-in reception of a beverage. A visual pour line may be integrally formed flush with a smooth interior surface of the sidewall and integrally formed flush with a smooth exterior surface of the sidewall and provide a visual indication of an amount of liquid within the dinking glass, e.g., 16 or 20 ounces. Moreover, a central projection may extend upwardly from the base and to an interior of the upwardly extending outer sidewall and cooperate therewith to form a generally recessed annular moat therebetween. Also, an aeration tab may extend from the central projection and be positioned to disrupt laminar flow of the beverage when poured into the drinking glass.
