Patent number: 11313266Abstract: A mixer assembly for a vehicle exhaust system includes an inner wall surface and a flow diverter with a flow directing surface that is spaced apart from the inner wall surface to provide an exhaust gas inlet area. The flow directing surface terminates at a distal end that is spaced apart from the inner wall surface to provide an orifice between the distal end and the inner wall surface through which exhaust gas flow accelerates and is directed to flow along the inner wall surface. A vehicle exhaust component assembly that includes the mixer and a method for mixing injected fluid spray into the mixer are also disclosed.Type: GrantFiled: September 1, 2017Date of Patent: April 26, 2022Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Alfred N. Tucker, Tomasz Kozakeiwicz, Syed Saleem Quadri, Jeffery Prairie

Patent number: 11242790Abstract: 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.Type: GrantFiled: November 3, 2017Date of Patent: February 8, 2022Assignee: Faurecia Emissions Control TechnologiesInventors: Chris Chapman, Philip M. Dimpelfeld, Syed Saleem Quadri, Aejaz Ahmed

Patent number: 11230958Abstract: A vehicle exhaust system includes an injector assembly having an injector mount configured to mount an injector to an exhaust component. The injector mount includes a spray opening surrounding a spray axis. An injector housing extends from an inlet end that receives exhaust gases to an outlet end. The inlet end defines a planar area that is transverse to the spray axis. A spray protector extends axially from the injector mount to break the planar area. A vehicle exhaust component assembly comprising a mixer with the injector assembly and a method for injecting a fluid into an exhaust component using the injector assembly are also disclosed.Type: GrantFiled: February 24, 2017Date of Patent: January 25, 2022Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Alfred N. Tucker, Tomasz Kozakeiwicz, Syed Saleem Quadri, Jeffery Prairie

Patent number: 11105241Abstract: A vehicle exhaust system includes an injector assembly having a cone positioned adjacent to an injector mount and which extends from an upstream inlet end to a downstream outlet end. Engine exhaust gas and injected spray enter the inlet end of the cone to mix with each other prior to exiting the cone via the outlet end. The cone has a narrowing body portion located downstream of the inlet end to accelerate flow during mixing. A vehicle exhaust component assembly comprising a mixer with the injector assembly and a method for injecting a fluid into an exhaust component using the injector assembly are also disclosed.Type: GrantFiled: August 30, 2017Date of Patent: August 31, 2021Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Alfred N. Tucker, Tomasz Kozakeiwicz, Syed Saleem Quadri, Jeffery Prairie

Patent number: 11085346Abstract: A vehicle exhaust system includes an exhaust component having an inner wall to define an internal cavity that provides an engine exhaust gas flow path from an inlet to an outlet. An injector is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inlet baffle is mounted to the exhaust component adjacent the inlet and includes at least one scoop having a scoop length that is greater than a scoop width. The scoop includes a scoop opening that directs engine exhaust gas toward the inner wall of the internal cavity at a location that is upstream of spray injected by the injector.Type: GrantFiled: May 31, 2017Date of Patent: August 10, 2021Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Alfred N. Tucker, Tomasz Kozakeiwicz, Syed Saleem Quadri, Jeffery Prairie

Patent number: 9267417Abstract: A diffuser plate for a vehicle exhaust system comprises a body having a primary opening and a plurality of secondary openings circumferentially spaced apart from each other about the primary opening. In one example, the diffuser plate is positioned between an exhaust manifold and a catalytic converter. Exhaust gas from the exhaust manifold flows through the primary and secondary openings in the diffuser plate to provide a thorough mixed flow that is evenly distributed across an inlet to a catalyst substrate, and also enable an oxygen sensor to accurately measure engine cylinder exhaust gas chemistry.Type: GrantFiled: October 31, 2013Date of Patent: February 23, 2016Assignee: Faurecia Emissions Control Technologies USA, LLCInventors: Steven R.
