PURPOSE:To supply fuel mixed with the lubricating oil of a proper mixing ratio all the times by a method wherein a fuel tank is provided together with a lubricating oil tank and the lubricating oil is discharged into the fuel by a pump cooperating with a change of a liquid level of the fuel. CONSTITUTION:When the oil is poured into the lubricating oil tank 4, the oil is filled within a pump 7 through a suction valve 81. When the fuel is poured into a fuel tank 1 under this condition, the pump 7 is operated by an elevation of a float 12 and the oil in the pump is discharged into the fuel by opening a discharging valve 91. When an engine is operated and a liquid level of the fuel in the tank 1 is descended, the float 12 is descended in accompanied therewith and a diaphragm 72 is lifted up through a lever 11, thereby, a pressure in a pump chamber 71 is decreased. Due to the decrease, the discharging valve 91 is closed, the suction valve 81 is opened and the lubricating oil in the tank 4 is sucked into the pump chamber 71 through a suction pipe 8. By suplementing the fuel into the tank 1, the lubricating oil in the pump chamber 71 is discharged again in the same manner. |
