の燃料噴射装置。A main injector disposed on the upstream side of a throttle valve provided in an intake passage facing the throttle valve, and a cold start injector that injects fuel into the intake passage when the engine is started in a cold state. In a fuel injection device for an internal combustion engine, a fuel spray angle range of the main injector is defined as a range of full throttle opening degrees of the throttle valve, such that the position where the sprayed fuel reaches the throttle valve surface is from a fully closed state to a fully open state. The main injector is always placed closer to the downstream opening tip than the upstream opening tip of the throttle valve. 1. A fuel injection device for an internal combustion engine, characterized in that the fuel injection device is disposed in a plane substantially orthogonal to a central axis and passes through a position near a downstream opening tip of the throttle valve at an idle opening.
