  • Systems and methods for reliably detecting wear metal particles in lubrication systems to avoid progressive damage
    Patent number: 11828743
    Abstract: A controller includes at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to: perform operations comprising: determining a concentration of a plurality of wear metal particles in a lubricant for an engine system; determining a filtered concentration of the plurality of wear metal particles using a baseline concentration of the plurality of wear metal particles; setting a diagnostic threshold based on the filtered concentration of the wear metal particles; and, responsive to determining that the concentration of the wear metal particles exceeds the diagnostic threshold, providing a notification.
    Type: Grant
    Filed: October 19, 2022
    Date of Patent: November 28, 2023
    Assignee: Cummins Inc.
    Inventors: Travis A. Anderson, Neha Chandrachud, Renae Christianson, Lorraine H. Myers, Pallav Pathak, Patrick J. Shook

  • Systems and methods for reliably detecting wear metal particles in lubrication systems to avoid progressive damage
    Patent number: 11499454
    Abstract: Systems and apparatuses relate to a system comprising a controller comprising at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising: determining a concentration of a plurality of wear metal particles in a lubricant for an engine system; determining a confidence parameter regarding the concentration determination; determining a filtered concentration of the plurality of wear metal particles using a baseline concentration of the plurality of wear metal particles; setting a diagnostic threshold for the plurality of wear metal particles based on the confidence parameter; and, responsive to determining that the diagnostic threshold is exceeded, providing a notification.
