とする、２サイクルエンジンの排気制御装置。 A two-stroke engine equipped with a variable exhaust timing device in an exhaust port of a cylinder, including a variable cross-sectional area device that narrows the cross-sectional area of the exhaust passage in conjunction with the variable exhaust timing device, and the variable exhaust timing device delays the exhaust timing. When the cross-sectional area variable device is used to reduce the cross-sectional area of the exhaust passage, when the exhaust timing variable device is at the position where the exhaust timing is most advanced, the cross-sectional area variable device is arranged to form a substantially continuous surface with the inner wall of the exhaust passage. An exhaust control device for a two-stroke engine, characterized by:
