ローク内燃機関。 In a two-stroke internal combustion engine in which a piston opens and closes a scavenging port and an exhaust port that are open on the side of the cylinder, a deflector portion that gradually becomes higher from the scavenging port side toward the exhaust port side is formed at the top of the piston, and A recess is formed in the exhaust port side part so that the upper edge position of the piston on the exhaust port side is lower than the upper edge position on the scavenging port side, and the cylinder head is provided with a wall surface that can be brought into substantially close contact with the upper surface of the deflector part. At the same time, a recess with an ignition plug is formed on the exhaust port side to define a combustion chamber on the exhaust port side between the piston and the exhaust port opening on the side of the cylinder. A two-stroke internal combustion engine characterized in that an upper edge position is set lower than an upper edge position of a scavenging port.
