摘要： A vehicle exhaust system includes an inlet module configured to receive engine exhaust gas and a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module. An injection component is positioned within the internal cavity and has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component defines an injection axis and includes an inner structure defining an inner gas flow path and an outer structure defining an outer gas flow path that is between the inner and outer structures and radially outward of the inner gas flow path to improve mixing at the fluid outlet. An outlet module is configured to direct a mixture of engine exhaust gas and fluid to a downstream exhaust component.

摘要： A vehicle exhaust component assembly includes an inlet module configured to receive engine exhaust gas, a mixer housing defining an internal cavity that receives engine exhaust gas from the inlet module, and an injection component defining an injection axis and positioned within the internal cavity. The injection component has a fluid inlet and a fluid outlet to direct injected fluid into the internal cavity to mix with the engine exhaust gas. The injection component comprises at least a first curved sheet and a second curved sheet that cooperate with each other to surround the injection axis, wherein the second curved sheet is offset from the first curved sheet by a radial gap to create a swirling gas flow within the injection component to mix with fluid injected via the fluid inlet. An outlet module directs a mixture of engine exhaust gas and fluid to a downstream exhaust component.

摘要： A vehicle exhaust system includes a mixer and a doser that sprays a reducing agent into the mixer to be thoroughly mixed with engine exhaust gases prior to introduction of the mixture into a downstream exhaust component. The mixer includes an upstream baffle with at least one inlet opening and a downstream baffle with at least one outlet opening. An outer peripheral wall surrounds the upstream and downstream baffle and includes a doser opening. A doser is mounted at the doser opening and is configured to spray a reducing agent into an area between the upstream and downstream baffles. A deflector is positioned between the inlet opening and the doser opening to protect spray at the doser opening from direct impact with exhaust gas from the inlet opening, and an impactor is positioned adjacent the deflector and faces the doser opening.

摘要： A mixer assembly for a vehicle exhaust system includes a mixer shell defining an internal cavity, wherein the mixer shell includes an upstream end configured to receive exhaust gases and downstream end, and a reactor positioned within the internal cavity. The reactor has a reactor inlet configured to receive injected fluid and a reactor outlet that directs a mixture of exhaust gas and injected fluid into the internal cavity. An inlet baffle is mounted to the upstream end of the mixer shell. The inlet baffle includes at least one opening that directs exhaust gas into at least one exhaust gas inlet to the reactor and a plurality of bypass openings that direct exhaust gas to bypass entry into the reactor. The inlet baffle includes a crowned portion that curves away from the reactor to provide for an increased open area within the internal cavity between the inlet baffle and the reactor.

摘要： A mixer for a vehicle exhaust gas system includes a mixer housing defining an internal cavity and having a mixer inlet configured to receive exhaust gas and a mixer outlet to direct exhaust gas to downstream exhaust components. A flow device is configured to receive the exhaust gas from the mixer inlet and to facilitate mixing of the exhaust gas and a reductant introduced into the first flow device. The flow device comprises a Venturi body centered on a body center axis, and the Venturi body comprises a body inlet configured to receive the exhaust gas from the mixer inlet and a body outlet configured to provide the exhaust gas to the mixer outlet. The Venturi body also includes a louver extending from an internal surface of the mixer housing to a distal edge that is downstream of the body outlet. An upstream vane is positioned within the Venturi body proximate the body inlet and is coupled to an upstream vane hub that is centered on an upstream vane hub axis. A downstream vane is positioned within the Venturi body proximate the body outlet and is coupled to a downstream vane hub that is centered on a downstream vane hub axis. The upstream vane hub axis is radially offset from the body center axis by an offset distance and/or the downstream vane hub axis is radially offset from the body center axis by an offset distance.

摘要： A mixer for a vehicle exhaust system includes a mixer housing that defines an interior cavity for engine exhaust gases, and which includes a doser opening formed within a wall of the mixer housing. A cone has a cone inlet opening aligned with the doser opening and a cone outlet into the interior cavity. A diverter has at least one first opening that is open to the interior cavity and a second opening that surrounds the cone outlet. Exhaust flow is directed by the diverter to the cone inlet opening to be mixed with a fluid injected through the doser opening.
