SHUT-OFF VALVE FAULT DIAGNOSIS DEVICE AND FUEL SUPPLY SYSTEM |
摘要 |
Provided is a shut-off valve fault diagnosis device that performs fault diagnosis of a first shut-off valve that is disposed immediately after a gaseous fuel tank and a second shut-off valve that is disposed immediately before a regulator in a gaseous fuel supply system. The shut-off valve fault diagnosis device includes a diagnosis processing unit that performs a valve-shutting control of the first shut-off valve, performs a valve-shutting control of the second shut-off valve after a predetermined time has passed since the valve-shutting control of the first shut-off valve, and performs fault diagnosis of the first shut-off valve and the second shut-off valve based on a variation tendency in a fuel pressure between the first shut-off valve and the second shut-off valve after performing the valve-shutting control of the second shut-off valve. |
