Abstract

PURPOSE:To obtain a valve which withstands high rotation and high compression and to enable generation of high horse power by controlling intake and exhaust through rotation of the valve in a four-cycle engine. CONSTITUTION:In order to open/close an intake and exhaust ports provided at a cylinder head of an engine, the intake and exhaust valves in the cylinder shape in which holes are formed in the diametral direction are rotatably provided. These intake and exhaust valves are synchronously rotated by rotation of a crank shaft of the engine through a timing belt. Thus, intake of mixture and exhaust of exhaust gas can be controlled synchronously with operation of the engine, and generation of high horse power is realized.
