供給装置。 Each cylinder has an intake valve driven by a camshaft, three intake ports that branch from the intake passage and open on one side of the combustion chamber through the intake valves, and at least two intake ports on both sides of the three intake ports. In a fuel supply device for an engine equipped with a fuel injection valve that injects fuel into each intake port, the intake ports on both sides are provided at both end positions of the cylinder bore on a center line of the cylinder bore that divides the combustion chamber into one side and the other side. A fuel supply device for an engine, wherein the central intake port is provided at an end position closer to the cylinder bore on one side of the combustion chamber than the intake ports on both sides.
