御装置。[Claims for Utility Model Registration] (1) A pressure receiving plate that rotates in response to the exhaust pressure of exhaust gas is rotatably supported in the exhaust port, and the rotational force of the pressure receiving plate is used to control the cylinder of the exhaust port. An exhaust control device for a two-stroke engine, characterized in that the exhaust valve is driven to change the position of the upper edge of a side opening. (2) The exhaust valve forms an upper wall located immediately after the cylinder-side opening of the exhaust port, and is rotated by a predetermined amount on a shaft arranged perpendicular to the flow direction of exhaust gas flowing inside the exhaust port. It is a plate that is supported so that it can rotate freely in angle.
One end of the plate located downstream of the exhaust port engages with one end of the pressure receiving plate and rotates by a predetermined rotation angle about the shaft in conjunction with rotation of the pressure receiving plate. An exhaust control device for a two-stroke engine as claimed in claim (1) of the utility model registration.
