。 In an internal combustion engine that has an intake port provided in the cylinder head and a poppet-type intake valve arranged in the intake port, the fuel injection valve injects rod-shaped fuel with a small spread toward the valve rim of the intake valve. In addition, a deflector is attached to the valve stem of the intake valve, and when the load is low, fuel is injected in a range where the valve lift of the intake valve is large, and the fuel flows through the valve of the intake valve. When the load is high, the fuel is injected from a small valve lift range including the closing of the intake valve to a large valve lift range, and in a small valve lift range, the fuel hits the deflector. A fuel injection device for an internal combustion engine, characterized in that the fuel is atomized as it rises.
