装置。 A secondary intake passage with a relatively large passage opening area connects to each cylinder via an intake branch pipe, and a primary intake passage with a relatively small passage opening area which introduces intake air independently to the secondary intake passage. A primary intake throttle valve that opens and closes in conjunction with the accelerator operation is provided in the primary intake passage, and a secondary intake throttle valve that opens with a delay with respect to the primary intake throttle valve is provided in the secondary intake passage, In the fuel supply device in which a fuel injection valve is provided in a primary intake passage on the downstream side of the primary intake throttle valve, a throttle part is provided in the primary intake passage on the downstream side of the fuel injection valve, and a throttle part is provided on the upstream side of the primary intake throttle valve. A fuel supply device for an internal combustion engine, comprising a pressurizing means for pressurizing intake air.
