  • Monitoring the fuel supply cutoff valve for an engine
    Patent number: 9470604
    Abstract: A method of testing an engine fuel supply cutoff valve includes: detecting a fuel supply cutoff command; commanding to close the fuel supply cutoff valve; commanding to hold the fuel metering valve in the open position for a predetermined time; commanding to close the fuel metering valve after the predetermined time; measuring an engine operating parameter during performance of the previous steps; and comparing the measured parameter with a predetermined threshold, so as to determine whether or not the engine operating parameter corresponds to an engine fuel supply cutoff by normal operation of the fuel supply cutoff valve.
