Abstract
A fuel supply device includes a sub fuel tank disposed in a return fuel line, a pressure reduction valve, and a recirculation cutoff valve. When an internal combustion engine stops, the fuel supply device opens the pressure reduction valve and closes the recirculation cutoff valve. Due to this first transfer state, a liquefied gas fuel in a common rail is transferred to the sub fuel tank. Thereafter, the fuel supply device closes the pressure reduction valve and opens the recirculation cutoff valve. Due to this second transfer state, the liquefied gas fuel in the sub fuel tank is transferred to a main fuel tank. The fuel supply device repeatedly alternates between the first and second transfer states to collect the liquefied gas fuel from the common rail to the main fuel tank.
