サイクルエンジンの排気時期制御装置。 An exhaust timing control device for a two-stroke engine that is attached to an upper part of an exhaust passage communicating with the inside of the cylinder of the two-stroke engine near the opening to the cylinder, the device comprising: a conical circumferential surface along the inner circumferential surface of the cylinder; It is formed into a substantially D-shaped cross section with a cutout surface along the inner wall surface of the passage, and by rotating about a rotation axis perpendicular to the axis of the cylinder, the helical circumferential surface moves above the opening of the exhaust passage. The valve body includes a valve body that operates to open and close, a storage recess that stores the valve body when the valve body is opened, and a valve body drive mechanism that opens and closes the valve body in accordance with the rotational speed of the engine. and the rotation shaft are connected via a crank arm.
Cycle engine exhaust timing control device.
