Abstract
PURPOSE: To prevent sucked air from flowing into an exhaust port during the over- lapping checking the lowering of the engine power by setting the projection of a projecting piece at a specified value after it is provided on the wall a combustion chamber between an inlet port and an exhaust port surrounding the inlet port.
CONSTITUTION: A circular-arc-shaped projecting piece 13 is formed integral on the surface 3 of a combustion chamber between an inlet port 4 and an exhaust port 5 while surrounding the inlet port 4. The projection of the projecting piece 13 is so arranged as to coincide the height of an undersurface periphery 14a of a bevel section 14 in an inlet valve when the inlet valve 9 and the exhaust valve 11 become the same in the lift level H during the overlapping thereof. In addition, the ends 13a and 13b of the projecting piece 13 are set at the optimal position. During the overlapping of the inlet and exhaust valves, the sucked air from the inlet port 4 is prevented from flowing into the exhaust port 5 with the projecting piece when and before they are the same in the lift level. Thereafter, the opening of the exhaust valve 11 is reduced so much to keep the sucked air from flowing into the exhaust port 5.
