PURPOSE:To make it possible to provide always a mixed fuel of a precise and optimum mixing ratio for a long time without a fuel metering means being damaged, by measuring the weight of a mixed fuel tank to know the increment weight of filled fuel. CONSTITUTION:When fuel is filled from a filling section 20 through a filling pipe 30, the weight of fuel in a mixed fuel tank 11 is increased in accordance with the increment of fuel so that a weighing spring 19 is further compressed. At this time a bellows section 24 is compressed by the bottom of the tank 11 so that lubrication oil in a lubrication oil sump 25 is forced to flow into a supply pipe 22. The lubrication oil flowing into the pipe 22 is inhibited from counterflowing into a lubrication oil tank 12 by means of a ball valve 28 in a check valve 26, but discharged from the opening section of the supply pipe 22 into the filling section 20 of the oil tank 11. The discharge amount of this lubrication oil is always set at a predetermined ratio with respect to the increment weight of filled fuel, thereby it is possible to provide an optimum mixed fuel. |
