Internal combustion, a two-stroke combustion point from which the exhaust stroke control can be adjusted to its Method for answer In an internal combustion engine, the two-stroke ignition point 1, which consists of the exhaust port 15, which opens the exhaust port 13 into the cylinder 15 and the exhaust control valve 21, is supported so that Can move back and forth in the direction of the cylinder center along the said exhaust port 13 and which allows at least part of the aforementioned exhaust port 13 on the side of the cylinder head 4 to block the concave of the The tongue body, which creates hollow holes from the cylinder head side to the crankcase side, is created in the exhaust control flaps. As mentioned above, 21 with the bottom wall 24, the side wall 25 and the control wall 26, the concave of the scaffold 18 to allow the aforementioned exhaust control valves 21 to be withdrawn from the said exhaust port. To the above, 15 will be built and contact holes 27 to allow space 45, which is enclosed by the recess, frame 18, and the valve body concave to contact the aforementioned exhaust channels. It has been fitted to the bottom 24 of the aforementioned exhaust control flaps 21 to provide an exhaust control device that provides a high level of engine output and The picture quality of the engine is obtained with stability from low to high operating speed in the engine. There is a two-stroke internal combustion point where the exhaust timing control can be adjusted. Method for answer: In an internal combustion engine, the second combustion point 1, which consists of the exhaust port 15, which opens the exhaust port 13 into the cylinder 15 and the exhaust control valve 21 to be supported so that It can move back and forth in the direction of the cylinder center along the exhaust port 13, and which allows at least part of the exhaust port 13 on the side of the cylinder head 4 to block the concave of. The tongue body, which creates a center hole from the lid side to the crank side, is created in the exhaust control flaps. As mentioned above, 21 with the bottom wall 24, the side wall 25 and the control wall 26, the concave of the scaffold 18 to allow the aforementioned exhaust control valves 21 to be withdrawn from the said exhaust port. To the above, 15 will be built and contact holes 27 to allow a space 45, which is enclosed by a frame concave 18, and a valve body concave to contact the aforementioned exhaust channels. 15 is provided on the bottom wall 24 of the aforementioned exhaust control flaps 21:
