Abstract
A fuel supply device includes: an injector that injects and supplies fuel to an engine; a pressure accumulator communicating with a cylinder of the engine through a communication passage; a valve that opens or closes the communication passage; and a controller that controls the injector and the valve. When the engine is rotated, an air-fuel mixture is compressed in the cylinder, and an accumulating portion of the controller accumulates the air-fuel mixture in the pressure accumulator. When the engine is restarted, a supplying portion of the controller supplies the air-fuel mixture accumulated in the pressure accumulator to the cylinder.
