Patent number: 10443470Abstract: Nitrogen oxide multiplexing systems are provided. Various embodiments provide for systems comprising an aftertreatment component configured to treat exhaust exiting an engine, a sensor, a conduit, and a switching device. The sensor is configured to detect nitrogen oxide in the exhaust from both upstream of and downstream of an aftertreatment component. The conduit has a first end positioned upstream of the aftertreatment component and a second end communicable with the sensor positioned downstream of the aftertreatment component. The conduit receives a sample of the exhaust flowing from upstream of the aftertreatment component through the first end and delivers the sample of the exhaust to the sensor through the second end. The switching device is connected to the conduit and configurable to selectively prevent the flow of exhaust upstream of the aftertreatment component from reaching the sensor.Type: GrantFiled: November 16, 2015Date of Patent: October 15, 2019Assignee: Cummins Emission Solutions, Inc.Inventor: Dale G. Gibby

Patent number: 9163523Abstract: One embodiment is an apparatus including a bearing housing mechanically coupled to a compressor housing on a first side and to a turbine housing on a second side. The compressor housing has a compressor outlet and the turbine housing has a fluid outlet. A first flow path fluidly connects the compressor outlet to a first circumferential channel formed between the bearing housing and the compressor housing. A fifth flow path fluidly connects the fluid outlet to a second circumferential channel formed between the bearing housing and the turbine housing. A third fluid flow path fluidly connects the first circumferential channel to the second circumferential channel. The apparatus further includes a fluid conduit that fluidly connects the fluid outlet to an actuator.Type: GrantFiled: June 25, 2012Date of Patent: October 20, 2015Assignee: Cummins Inc.Inventor: Dale G.

Patent number: 8251590Abstract: A bearing component and bearing assembly are disclosed. The bearing component includes structure for providing a hard rotation stop, in one embodiment, the anti-rotation structure includes a slot formed in at least one bearing component having a surface for supporting a bearing shell. The slot has a longitudinal axis at an oblique angle to a plane perpendicular to the surface for supporting the bearing shell. In other embodiments, a groove extends radially outward from a surface of at least one component for supporting a bearing shell to a side of the component. The groove has a depth that increases as a function of distance in a direction parallel with a center axis of the component.Type: GrantFiled: May 29, 2009Date of Patent: August 28, 2012Assignee: Cummins Intellectual Properties, Inc.Inventors: Dale G. Gibby, Joseph Rennekamp, Kent H. Clark

Patent number: 6364399Abstract: An elongated structural member of a vehicle frame. The structural member is hollow to form an elongated chamber. Filler material in the chamber is compressed by a source of pressure to press the filler material laterally outwardly against the walls of the chamber to strengthen the structural member and resist buckling. The filler material includes a flexible bag filled with small solid particles. The source of pressure may include one or more compression coil springs, or a tension rod or a gas generant.Type: GrantFiled: August 10, 2000Date of Patent: April 2, 2002Assignee: DaimlerChrysler CorporationInventor: Dale G.
