  • Methods and systems for cylinder bank misfire detection and reactivation
    Patent number: 9599048
    Abstract: Various systems and methods are described for deactivation and reactivation of a cylinder bank in a V-engine. In one example, the cylinder bank is deactivated responsive to an indication of misfire based on crankshaft acceleration and exhaust air fuel ratio. The cylinder bank is reactivated sequentially based on exhaust catalyst temperature.
    Type: Grant
    Filed: January 25, 2016
    Date of Patent: March 21, 2017
    Assignee: Ford Global Technologies, LLC
    Inventors: Chris Paul Glugla, Robert Sarow Baskins, Joseph Patrick Whitehead, Craig Alan Smith, Timothy Robert Gernant, Scott Richard Hughes

  • Systems and methods for improving catalyst diagnostics in the presence of sensor degradation
    Patent number: 9261033
    Abstract: Systems and methods for diagnosing operation of a catalyst are presented. In one example, threshold limits for catalyst variables are adjusted in response to attributes of a catalyst monitor sensor that may vary with sensor age. The catalyst variables may provide insight into whether or not the catalyst is degraded or operating as intended.

  • Method of inferring start-up misfires due to the build-up of ice and melt water in the intake system of a vehicle engine
    Patent number: 9175619
    Abstract: Methods are provided for determining ice formation during cruising under cold weather conditions at the intake manifold or throttle body of an engine system and for enabling engine misfire diagnostics upon detection of dissipation of the formed ice.

  • Integrated fuel catalyst monitor
    Patent number: 9097166
    Abstract: A method of monitoring catalyst performance may comprise applying a set of parameter readings for a given sample to a support vector machine to generate a classification output, clustering the set of parameter readings to reduce a number of support vectors, computing a total fuel mass following a deceleration fuel shut-off event and an exhaust gas oxygen sensor switch and indicating catalyst degradation based on the total fuel mass.
