Claims (1)
ンジン本体に形成し、該ケーシング内に駆動軸を
配設するとともに、該駆動軸のエンジン延長上に
位置する上記ケーシングの側壁にキヤツプを回動
自在に配設し、かつ該キヤツプと上記駆動軸とに
リターンスプリングを配設し、さらに上記駆動軸
に回動アームを固設し、該回動アームを弁体に係
合させ、上記リターンスプリングの付勢力によつ
て上記弁体の先端を排気口に臨ませて排気タイミ
ングを遅らせ、上記駆動軸を上記リターンスプリ
ングの付勢力に抗して回動させ、上記弁体の先端
を排気口から後退させて排気タイミングを早める
２サイクルエンジンの排気制御装置において、上
記駆動軸の一端を上記ケーシングの側壁に支承さ
せ、他端を上記キヤツプに支承させたことを特徴
とする２サイクルエンジンの排気制御装置。 A casing having an exhaust valve chamber is formed in the engine body, a drive shaft is disposed within the casing, and a cap is rotatably disposed on a side wall of the casing located on an extension of the drive shaft to the engine; Further, a return spring is disposed between the cap and the drive shaft, a rotating arm is fixed to the drive shaft, and the rotating arm is engaged with the valve body, so that the valve body is actuated by the biasing force of the return spring. The tip of the valve body faces the exhaust port to delay the exhaust timing, the drive shaft is rotated against the biasing force of the return spring, and the tip of the valve body is moved back from the exhaust port to adjust the exhaust timing. What is claimed is: 1. An exhaust gas control device for a two-stroke engine that speeds up the engine, characterized in that one end of the drive shaft is supported on a side wall of the casing, and the other end is supported on the cap.
