御装置。 An exhaust valve control device for a two-stroke engine in which an exhaust valve provided at an exhaust port to adjust its opening/closing timing is controlled from a servo motor via a cable member provided between two pulleys. The drive-side pulley is pivotally supported on the engine body, the driven-side pulley is mechanically drivingly connected to the operating shaft of the exhaust valve, and the rotation angle of the shaft is detected by the shaft of the driven-side pulley. An exhaust valve control device for a two-stroke engine, characterized in that an angle detection device is connected to the exhaust valve control device.
