Patent number: 11928806Abstract: A computer system is structured to determine a density of particulate matter in a diesel particulate filter (DPF) sample. The computer system includes a processing circuit having a processor and a memory. The processing circuit is structured to generate a computed tomography (CT) scan-based image of the DPF sample; and, segment the CT scan-based image of the DPF sample into a plurality of regions. For at least one region from the plurality of regions, the processing circuit is structured to determine a density of a portion of the DPF sample corresponding to the at least one region of the CT scan-based image of the DPF sample and cause an electronic display of a user device to display the CT scan-based image including the at least one region and an indication of the density for the at least one region.Type: GrantFiled: February 12, 2021Date of Patent: March 12, 2024Assignee: Cummins Inc.Inventors: Yujun Wang, Ben Wang, Carl Justin Kamp, Leigh Anne Rogoski, Rafael Ernesto Vasquez Lombardo, Michael J. Cunningham, Krishna Pradeep Chilumukuru, Neal W. Currier

Patent number: 11808683Abstract: A particulate filter inspection system for a particulate filter includes a compressed air source, a primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of the air within the primary conduit when the probe is providing air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge, compare the pressure to a target upper pressure, and provide an indication that the particulate filter is dirty if the pressure is not lower than the target upper pressure.Type: GrantFiled: January 11, 2022Date of Patent: November 7, 2023Assignee: Cummins Inc.Inventors: Krishna Pradeep Chilumukuru, James C. Clerc, Richard Adotey Allotey, Luis Fernando Loo Zazueta, Todd M. Wieland, Rafael Ernesto Vasquez Lombardo

Patent number: 11226277Abstract: A particulate filter inspection system for a particulate filter includes a compressed air source. A primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of a first portion of the air within the primary conduit when the probe is providing a second portion of the air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge and compare the pressure to a target upper pressure.Type: GrantFiled: December 23, 2019Date of Patent: January 18, 2022Assignee: Cummins Inc.Inventors: Krishna Pradeep Chilumukuru, James C.

Patent number: 11193853Abstract: A sensing assembly comprises a sensor housing having a sensing end and a coupling end opposite the sensing end. A sensing element and a heating element are disposed within the sensor housing. A tip cover and coupling end cover removably coupled to the ends of the sensor housing. The tip cover and coupling end cover are configured to be uncoupled from the sensor housing to enable removal of at least one of the sensing element, the heating element, or an integrated sensing/heating element from the sensor housing, and replacement with at least one of a new sensing element or a new heating element, the tip cover and coupling end cover configured to be recoupled to the sensor housing after at least one of the new sensing element or the new heating element is disposed in the sensor housing.Type: GrantFiled: January 23, 2020Date of Patent: December 7, 2021Assignee: Cummins Emission Solutions Inc.Inventors: Nathan A. Ottinger, Z. Gerald Liu, Rafael Ernesto Vasquez Lombardo, Krishna Pradeep Chilumukuru
