Three intake valves are arranged facing the combustion chamber of the cylinder head, and an intake port common to the three intake valves is branched into the center corresponding to each intake valve. In an internal combustion engine having branches formed into a port part and side branch port parts on both sides thereof, fuel injection injects fuel in three directions toward each of the branch port parts upstream of the branch point of the intake port. 1. A fuel supply device for an internal combustion engine, comprising a valve, and the amount of fuel injected into a central branch port of the fuel injection valve is set to be smaller than the amount of fuel injected into a side branch port. 2. The fuel supply device for an internal combustion engine according to claim 1, wherein the center of the central fuel spray is positioned approximately tangentially to the bottom surface of the central branch port.
