Patent number: 11293382Abstract: Multiple convergent nozzles define multiple flow passages in a flow path from an air inlet of the mixer to an outlet of the mixer. The convergent nozzles each converge toward the outlet of the mixer. An exhaust gas housing includes an exhaust gas inlet leading into an interior of the exhaust gas housing. Multiple convergent-divergent nozzles each correspond to one of the plurality of convergent nozzles. The convergent-divergent nozzles each include an air-exhaust gas inlet in fluid communication to receive fluid flow from a corresponding convergent nozzle and the interior of the exhaust gas housing.Type: GrantFiled: January 7, 2021Date of Patent: April 5, 2022Assignee: Woodward, Inc.Inventor: Daniel B. Mastbergen

Patent number: 10995705Abstract: A convergent nozzle is in a mixer housing and in a flow path from an air inlet of the mixer to an outlet of the mixer. A convergent-divergent nozzle is in the mixer housing and includes an air-exhaust gas inlet in fluid communication to receive fluid flow from the convergent nozzle and from the interior of the exhaust gas housing. A first nozzle module is configured to be received in the mixer housing and, when received in the mixer housing, define at least a portion of the convergent nozzle or the convergent-divergent nozzle. A second nozzle module is configured to be received in the mixer housing separate from the first nozzle module. The second nozzle module, when received in the mixer housing, is configured to define at least a portion of the convergent or the convergent-divergent nozzle. The second nozzle module has a different flow characteristic than the first nozzle module.Type: GrantFiled: February 7, 2019Date of Patent: May 4, 2021Assignee: Woodward, Inc.Inventors: Daniel B. Mastbergen, Domenico Chiera, Gregory James Hampson, Yi Han, James Po-Chang Chiu, Doug Leone, Henry David Gemmill Knutzen, Samuel James McCreery

Patent number: 8991157Abstract: An exhaust treatment system for an engine includes a regeneration device being in receipt of exhaust from the engine and positioned upstream of a diesel particulate filter. A compressor provides a source of compressed air. An air/fuel nozzle is coupled to the regeneration device, in receipt of a fuel supply as well as the compressed air. The fuel and compressed air are forced through an orifice of the nozzle to atomize the fuel. A bypass line provides compressed air from the compressor to the regeneration device without passing through the orifice of the nozzle. A valve is operable to allow compressed air to flow through the bypass line when a predetermined condition exists.Type: GrantFiled: January 30, 2012Date of Patent: March 31, 2015Assignee: Woodward, Inc.Inventors: Daniel B. Mastbergen, Clark Fraser Paterson, John Michael Williams, Lawrence Dalimonte, Nicholas Morley, Tom DePotter, Jagandeep Sandhu

Patent number: 8484956Abstract: A regeneration control system for use with a diesel engine having a diesel particulate filter is provided. This regeneration control system utilizes a wide band oxygen sensor placed in the exhaust stream upstream of a regeneration device, as well as an engine speed sensor, to determine when to initiate the regeneration event, and for controlling the regeneration device to ensure proper regeneration of the diesel particulate filter. The after treatment controller utilizes the oxygen percentage signal to calculate or otherwise determine the percentage load at which the diesel engine is operating. This information along with the engine speed information allows the after treatment controller to calculate or otherwise determine exhaust parameters necessary for proper control of the regeneration device.Type: GrantFiled: February 8, 2011Date of Patent: July 16, 2013Assignee: Woodward, Inc.Inventor: Daniel B.
