Abstract
A fuel supply apparatus for an internal combustion engine includes a motor, a fuel pump, an alternator, a centrifugal clutch, and an electronic control unit. The centrifugal clutch is configured to, when the rotation speed of the output shaft of the motor is higher than or equal to an engaging rotation speed, connect the output shaft of the motor with the rotary shaft of the alternator. The engaging rotation speed is a rotation speed higher than a rotation speed of the rotary shaft at which torque that acts on the rotary shaft as a result of generation of electric power by the alternator becomes maximum and is a rotation speed lower than a rotation speed at which torque for driving the high-pressure fuel pump cannot be provided by only the motor at the time when the motor is driven at rated output power.
