特徴とする２ストロークエンジン。 An intake valve that opens and closes each intake port or exhaust port in synchronization with the crank angle, with an intake port that allows intake air pumped from the supercharger to flow into the combustion chamber, and an exhaust port that also allows burned gas to flow out from the combustion chamber. Alternatively, in a two-stroke engine equipped with an exhaust valve, a means is provided in the combustion chamber to generate an exhaust swirl by the exhaust gas flow flowing out to the exhaust port, and a means to also generate an intake swirl by the intake flow flowing into the combustion chamber from the intake port. A two-stroke engine characterized in that the exhaust swirl and the intake swirl are configured to rotate in opposite directions to each other.
