Patent number: 10337379Abstract: A mixer assembly includes an outer housing having an inlet area that receives exhaust gas from an upstream exhaust component and an outlet area that directs exhaust gas to a downstream exhaust component. The outer housing includes an outer wall extending outwardly from the base wall about a periphery of the base wall and a deflector wall that directs exhaust gas from the inlet area to the outlet area. The deflector wall has a portion spaced from the outer wall to define a flow guide path that first directs exhaust gas flow from the inlet area in a first direction against a first portion of the outer wall and then directs exhaust gas flow in a second direction against a second portion of the outer wall that is transverse to the first portion.Type: GrantFiled: February 7, 2014Date of Patent: July 2, 2019Assignee: FAURECIA EMISSIONS CONTROL TECHNOLOGIES, USA, LLCInventors: Philip M.

Patent number: 10294843Abstract: A vehicle exhaust system includes an exhaust component defining an engine exhaust gas passageway and which includes an opening. A doser defines a doser axis and extends to a doser tip that is configured to spray a reducing agent into the engine exhaust gas passageway through the opening. A cone has a base end positioned adjacent the opening such that an annular gap is formed within the exhaust component around the doser tip. Exhaust gas is directed into the base end of the cone through the annular gap in a direction transverse to the doser axis. This configuration reduces deposit formation while still allowing the reducing agent to be thoroughly mixed with engine exhaust gases prior to introduction of the mixture into a downstream exhaust component.Type: GrantFiled: November 30, 2016Date of Patent: May 21, 2019Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Eduardo Alano, Philip M.
