MONITORING THE FUEL SUPPLY CUTOFF VALVE FOR AN ENGINE

摘要

Method of testing an engine fuel supply cutoff valve, characterised in that it comprises steps to:;detect (E1) a fuel supply cutoff command,;command (E3) to close the fuel supply cutoff valve,;command (E4) to hold the fuel metering valve in the open position for a predetermined time,;command (E5) to close the fuel metering valve after the predetermined time,;measure (E6) an engine operating parameter during performance of the previous steps,;compare (E7) 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.
