  • System for limiting engine output power by controlling fueling
    Patent number: 8266905
    Abstract: A method for controlling fueling of an internal combustion engine is provided. The engine may include an intake manifold, one or more exhaust manifolds and a turbocharger coupled between the intake and exhaust manifolds. The method may comprise estimating an operating condition of the turbocharger, determining a maximum value of an operating parameter as a function of the estimated operating condition of the turbocharger, measuring a value of the operating parameter, determining an error value as a function of the maximum value of the first operating parameter and the measured value of the operating parameter, and limiting fuel supplied to the engine based on the error value.
    Type: Grant
    Filed: May 24, 2010
    Date of Patent: September 18, 2012
    Assignee: Cummins Inc.
    Inventors: David J. Reynolds, Zachary Schwab, Ralph Gutman
