ものに蘭する。DETAILED DESCRIPTION OF THE INVENTION The present invention is an exhaust gas control device for a two-cycle internal combustion engine, which includes a piston whose cross-sectional height is variable by a sliding valve in order to prevent intake air from being discharged in a low rotational speed range. This type of cylinder is equipped with an exhaust slit in the cylinder wall.

れるヨツト気スリットが設けであるＷｉｆがある。A high-performance two-stroke internal heat engine no longer exerts a small rotational moment in the low rotational speed range because a portion of the intake air escapes into the exhaust pipe through the large length of the exhaust slit. Exhaust control systems for two-cycle internal combustion engines are known, however, in which a rotary valve is installed in the exhaust pipe, which enables supercharging regardless of the symmetric control data of the exhaust slot controlled by the piston. However, even with these structures, an extremely small rotational moment is exerted in a low rotational speed range. In order to eliminate the above-mentioned drawbacks and to achieve a good rotational moment even in a low rotational speed range, Wifs are available in which the length of the exhaust slit is variable or is provided with an additionally controlled exhaust slit.

ない。Stroke limitation of the flat sliding valve is achieved by a stopper. A spring holds the flat slide valve in the starting position. With the structure according to the present invention, exhaust hole cross-section control adapted to the operating conditions is achieved, and both good peak output when the exhaust hole cross section is narrow and a wide rotational speed range depend on the rotational speed and load. This will be achieved by changing the length of the exhaust slit. The control of the flat-slide valve takes place automatically as a function of the exhaust gas pressure in the exhaust pipe or in the exhaust gas system. Due to this 7t, the structure of the 114 control device is simple and the number of wear parts is small.
