Abstract
A fuel supply device () for an engine () pressurizes the fuel drawn up from a fuel tank () by the low-pressure fuel pump () and stores it in a delivery pipe (), and injects the fuel stored in the delivery pipe () from an injector (). The fuel supply device () includes a return passageway () connecting the delivery pipe () and the fuel tank (), and a relief valve () that is provided on the return passageway () and that is capable of being switched between an open state for connecting the delivery pipe () and the fuel tank () in communication and a closed state for shutting off the delivery pipe () and the fuel tank () from each other in communication. An ECU () switches the relief valve () to the open state and operates the low-pressure fuel pump (), if a predetermined stop condition for stopping the engine () is satisfied.
