ABSTRACT:
A fuel supply apparatus suppresses bubble generation of fuel in a delivery pipe and fuel leakage while suppressing power consumption. The fuel supply apparatus includes a fuel supply controller which is provided with a state determining unit that determines at least one of bubble generation of fuel in the delivery pipe and fuel leakage from a fuel injection valve to which fuel is supplied via the delivery pipe, and a fuel pressure controlling unit that activates a fuel feeding unit when the bubble generation is expected and activates a fuel pressure decreasing unit when the fuel leakage is expected. The fuel supply controller intermittently activates during the suspension of the operation of internal combustion engine using a timer, to adjust fuel pressure in the delivery pipe.
