Valve operating system for internal combustion engine |
摘要 |
A valve operating system includes: a decompression cam member that is provided on a camshaft, and moves between an operative position C where an exhaust tappet is operated in a valve opening direction in a compression stroke and an inoperative position D where the exhaust tappet is released; an exhaust gas recirculation cam member that is provided on the camshaft, and moves between an inoperative position F where the exhaust tappet is released and an operative position G where the exhaust tappet is operated in a valve opening direction in an intake stroke of the engine; and a common centrifugal mechanism that is driven by the camshaft to operate the decompression cam member to the operative position C in a starting rotation region of the engine and to the inoperative position D after the starting, and operate the exhaust gas recirculation cam member to the inoperative position F in a low speed operation region of the engine and to the operative position G in a high-speed operation region. Thus, the valve operating system can exert both a decompression function and an exhaust gas recirculation function.
