<p>PURPOSE: To accurately and easily perform detection of abnormalities by judging abnormal fuel transfer when pressure of transfer fuel does not reach the specified pressure within the specified time from the start of transfer when fuel is transferred from an auxiliary fuel tank to a main fuel tank. CONSTITUTION: Fuel in a main fuel tank 10 divided into two sections 12, 14 is supplied to engines 28, 30 through engine supply lines 36, 38 interposedly mounted with valves 32, 34. An inner main tank pipe 16 provided on the section 12 is connected to an auxiliary tank pipe 50 connected to a plurality of auxiliary tanks 52, 60 and 66 through a switch valve 48. In this case, pressure of a line 46 is detected by a pressure sensor 106 during fuel transfer from the auxiliary tank to the main fuel tank. If fuel pressure does not reach the specified pressure within the specified time from the start of transfer or if the fuel change rate of a main fuel tank level is less than a specified value, it is judged that fuel transfer is abnormal.</p> |
