サイクルエンジンの排気時期制御装置。 A recess is provided in the upper part of the exhaust passage and near the exhaust port, a rotating shaft is provided in the recess so as to be substantially orthogonal to the axis of the cylinder, and a plate-shaped valve body is attached to the rotating shaft so that the tip thereof is connected to the exhaust port. The rotating shaft is rotated in accordance with the rotational speed of the engine, and the swinging tip of the valve body substantially moves the upper end position of the exhaust port up and down, thereby changing the exhaust timing of the engine. 2, further comprising a biasing member that biases the rotation shaft in its axial direction to bring the valve body into contact with the inner surface of the recess.
Cycle engine exhaust timing control device.
