Abstract
A fuel supply device includes a fuel tank, a delivery pipe in which gas fuel to be supplied to a fuel injection valve is stored, a supply passage through which the fuel gas supplied from the fuel tank to the delivery pipe flows, a shut-off valve provided in the supply passage, an oil supply device that supplies oil to a downstream portion of the supply passage, and a controller. The controller executes an oil supply process during operation of the internal combustion engine to close the shut-off valve to stop the supply of the gas fuel to the delivery pipe, and supply the oil to the downstream portion by the oil supply device when the pressure in the delivery pipe has dropped.
