うにした２サイクル内燃機関。 A mask wall extending from the inner wall surface of the cylinder head toward the combustion chamber is formed between the intake valve and the exhaust valve, and the opening between the peripheral edge of the intake valve located on the exhaust valve side and the valve seat is opened by the mask wall to supply air. A scavenging port is formed on the inner wall surface of the cylinder below the intake valve that opens into the combustion chamber when the piston reaches near the bottom dead center, and is closed during the full opening period of the valve. A two-stroke internal combustion engine that supplies air into the combustion chamber from the scavenging port when the scavenging air reaches the combustion chamber.
