<P>PROBLEM TO BE SOLVED: To provide a fuel supply system that controls fuel injection to be started at a proper time after supplying power to a kick pilot cutoff valve to prevent shortage of fuel supply. <P>SOLUTION: This fuel supply system includes a cutoff valve having a first valve element which is arranged in a fuel supply passage leading to a regulator from a gas fuel tank and opens a valve earlier when power is supplied, and a second valve element that opens the valve by differential pressure reduction between the upstream side and the downstream side after the above valve is opened. The fuel supply system is configured to include: a first pressure sensor for detecting upstream fuel pressure of the cutoff valve as first fuel pressure; a second pressure sensor for detecting downstream fuel pressure of the cutoff valve as second fuel pressure; and a fuel injection control device for starting gas fuel injection after a preset delay time elapses from the start of power supply to the cutoff valve when the first fuel pressure and the second fuel pressure are less than a threshold value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
