(54) OIL STORAGE AMOUNT DETERMINATION DEVICE


(57) An oil storage amount determination device that determines the amount of oil stored in a tank (35), wherein the tank (35) is constructed such that a gaseous fuel that has been decompressed by a decompression valve (33) flow into the tank, a separation unit (36) that separates oil from the gaseous fuel is provided in the tank (35), and a temperature sensor (41) is supported in a side wall of the tank. This oil storage amount determination device is equipped with a determination unit (50) constructed so as to determine whether the temperature sensor (41) is immersed in the oil separated from the gaseous fuel by the separation unit (36). The determination unit (50) is constructed such that when the flow speed of the gaseous fuel flowing into the tank (35) changes, the determination unit determines whether the temperature sensor (41) is immersed in oil on the basis of the state of the change in the flow speed and the state of the change in the temperature detected by the temperature sensor (41).
