Patent number: 10337380Abstract: A vehicle exhaust system includes an outer housing defining an internal cavity surrounding an axis, an inlet baffle configured to direct engine exhaust gas into the internal cavity, and an injector that is configured to spray a fluid into the internal cavity to mix with engine exhaust gas. An inner wall is spaced radially inward of an inner surface of the outer housing to define a gap. The inner wall has an impingement side facing the axis and a non-impingement side facing the gap. At least one heat transfer element is positioned within the gap and in is contact with at least one of the inner surface of the outer housing and the non-impingement side of the inner wall to transfer heat through the inner wall to the impingement side to reduce spray deposit formation.Type: GrantFiled: July 7, 2017Date of Patent: July 2, 2019Assignee: Faurecia Emissions Control Technologies, USA, LLCInventors: Robin Willats, Jerome Brian Hornback, Tony Parrish, John G.

Patent number: 8881718Abstract: A fuel-fired combustor includes a housing with a combustion chamber. The housing has an inlet and an outlet. A fuel inlet to the housing supplies fuel to the combustion chamber. An igniter ignites a mixture of exhaust gas and fuel to produce a flame for increasing an internal temperature. At least one sensor measures or monitors at least one combustor characteristic and generates a corresponding combustor characteristic signal. A controller receives the combustor characteristic signal, compares the combustor characteristic signal to a predetermined combustor criteria and generates an output signal to change at least one combustor operating condition if the combustor characteristic signal varies from the predetermined combustor criteria.Type: GrantFiled: August 4, 2010Date of Patent: November 11, 2014Assignee: Faurecia Emissions Control Technologies USA, LLCInventors: Tony Parrish, Samuel N.

Patent number: 8397557Abstract: A method and apparatus for identifying a component failure within a thermal regenerator operates as follows. The burner control unit monitors at least one of a fuel pump characteristic for a fuel pump and an ignition system characteristic for an ignition system. The fuel pump is used to supply fuel to a fuel-fired burner and the ignition system is used to ignite fuel supplied to the fuel-fired burner. The fuel pump characteristic is communicated to the burner control unit which compares the fuel pump characteristic to a predetermined fuel pump criteria. The ignition system characteristic is communicated to the burner control unit which compares the ignition system characteristic to a predetermined ignition system criteria. The burner control unit identifies a fuel pump failure when the fuel pump characteristic does not meet the fuel pump criteria, and identifies an ignition system failure when the ignition system characteristic does not meet the ignition system criteria.Type: GrantFiled: October 21, 2009Date of Patent: March 19, 2013Assignee: Emcon Technologies LLCInventors: Tony Parrish, Wilbur H.
