Claims

[Scope of utility model registration request]

A low-lift, low-speed rotation cam and a high-lift, high-speed rotation cam are arranged side by side on the camshaft, and are operatively connected to a common valve operating member through low-speed and high-speed lifters, respectively, to improve the performance of the internal combustion engine. When the internal combustion engine rotates at low speed, the high-speed lifter moves freely, so that the valve operating member is driven via the low-speed rotation cam and the low-speed lifter, and when the internal combustion engine rotates at high speed, the high-speed lifter is driven by the low-speed lifter. A valve operating system for an internal combustion engine, characterized in that the valve operating member is driven via a high-speed rotation cam and a high-speed lifter.
