燃機関の燃料噴射装置。[Scope of Claim for Utility Model Registration] Combustion in a two-stroke internal combustion engine that is equipped with an intake valve and an exhaust valve, and the closing timings of the intake and exhaust valves are set so that the intake valve closes after the exhaust valve closes. a fuel supply means for directly supplying fuel into the combustion chamber; a rotation speed detection means for detecting the rotation speed of the engine; and when the engine is at low rotation speed, the fuel supply into the combustion chamber is started after the intake valve is closed. and a control means for operating the fuel supply means so as to start supplying fuel into the combustion chamber after the exhaust valve is closed and before the intake valve is closed when the engine is running at high speed. A fuel injection device for a two-stroke internal combustion engine, characterized in that the following are provided.
