  • Patent number: 11799271
    Abstract: Spark plugs are disclosed that include electrode arrangements to improve the charge flow into and out of the annular volume around the insulator nose and a pre-chamber volume of a pre-chamber device, thus directing a purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device.
    Type: Grant
    Filed: February 15, 2021
    Date of Patent: October 24, 2023
    Assignee: Cummins Inc.
    Inventors: David Guillermo Gonzalez Medina, William Marshall Cover, Xu Han, Andrew Guy Kitchen, Daniel J. O'Connor, Alan C. Anderson, Nicholas James Welch, Jisang Sun
  • Patent number: 11384700
    Abstract: Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.
    Type: Grant
