Abstract
A fuel injection structure for an internal combustion engine includes a straight intake port defining passage formed in an intake passage of the engine and a fuel injection valve disposed within a passage-defining wall which defines the straight intake port defining passage therein. The fuel injection valve is arranged inside the intake passage in parallel with a passage axis of the straight intake port defining passage in an elevational view of the engine. The fuel is injected from the fuel injection valve and flows in parallel with the intake air flow. Due to the parallel flow of the fuel and the intake air, the injected fuel does not tend to adhere to the wall surface of the intake port defining passage. This parallel flow is not affected by a change in the speed of the intake air flow.
