ABSTRACT:
Two stroke engine having variable exhaust timing, which includes an exhaust timing control member disposed in the exhaust passage in the vicinity of the exhaust port. The control member is of an arcuately curved contour having diameter gradually decreasing from one end toward the other end so that it can readily be assembled in the cylinder simply by inserting from one side of the cylinder. The control member has a longitudinal axis which is inclined with respect to a line perpendicular to a line passing through the center axis of the cylinder and the center of the exhaust port so that the smaller diameter end is closer to the center axis of the cylinder than the large diameter end for making it possible to locate the arcuately curved contour of the control member substantially along the cylinder wall.
