  • Method and apparatus for detecting selective catalytic reduction injector opening time
    Patent number: 9759116
    Abstract: A method for detecting an opening time of a valve, includes receiving a valve current profile of the valve and processing the valve current profile using at least a slope reflection detector to determine a status of the valve based on an output of the slope reflection detector.
    Type: Grant
    Filed: October 29, 2013
    Date of Patent: September 12, 2017
    Assignee: Continental Automotive Systems, Inc.
    Inventors: Ninsheng Qiao, Donald Peter Kultgen, Marvin Lester Lynch
  • Method to reduce engine combustion and harmonic noise for misfire detection
    Patent number: 9523322
    Abstract: A method and system for determining combustion and harmonic noise correction factors for current operating conditions corresponding to the actual vehicle and applying the combustion and harmonic noise correction factors to a sensor signal, thereby removing engine combustion and harmonic noise from the sensor signal and leaving a misfire data signal in the sensor signal.
