射装置。 It has an air intake port provided in the cylinder head and a poppet-type air intake valve placed in the air intake port, and when the intake valve is opened, fresh air forms a swirl around the cylinder axis within the combustion chamber. In an internal combustion engine, the fuel injection valve is arranged to inject rod-shaped fuel with a small spread from the valve stem of the intake valve toward the valve head portion on one side, and the fuel injected from the fuel injection valve A fuel injection device for an internal combustion engine, wherein the swirl is atomized when it hits the valve head portion, and is reflected in a direction opposite to the flow direction of the swirl.
