Abstract
A valve operating system for an internal combustion engine, which includes a decompression cam member () that is supported on a camshaft () and that operates an exhaust valve operating member () in an opening direction of an exhaust valve () in a compression stroke when the engine is started, an exhaust gas recirculation cam member () that is supported on the camshaft () and that operates the exhaust valve operating member () in the opening direction of the exhaust valve () in an intake stroke when the engine is running at high speed, and a centrifugal mechanism () that is mounted on a driven timing rotating member () rotating integrally with the valve operating cam () and makes the decompression cam member () and the exhaust gas recirculation cam member () move, wherein the valve operating cam () is provided with a recess () surrounding the camshaft (), the recess () opening on the face on the other side of the driven timing rotating member () and on a base face of the valve operating cam (), and the decompression cam member () and the exhaust gas recirculation cam member () are housed in the recess (). This can provide a valve operating system for an internal combustion engine that can be made compact in spite of a driven timing rotating member and an exhaust cam being installed.
