VALVE SYSTEM OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To improve a dynamic characteristic of a valve system by securing rigidity equivalent to a weight increase. SOLUTION: The dynamic characteristic of the valve system is improved by securing the rigidity equivalent to a weight increase by forming a diameter D1 of a suction side rocker shaft 2 larger than a diameter D2 of an exhaust side rocker shaft 3 (for example, about 10%).
