Abstract
PURPOSE:To improve an engine speed limit by installing a detachable mechanism in space between a high-speed rocker arm and a low-speed rocker arm, and separating both these rocker arms from each other at time of high engine speed. CONSTITUTION:A high-speed cam 11 and a low-speed cam 12 are installed in a camshaft 1. A high-speed rocker arm 6 having a part 15 abutting, with the high-speed cam 11 and a low-speed rocker arm 7 having a part 14 abutting with the low-speed cam 12 are supported on a rocker shaft 2 free of rocking motion. A detachment mechanism 30 is installed in space between the high-speed rocker arm 6 and the low-speed rocker arm 7, and these rocker arms 6, 7 are separated from each other at the time of high engine speed. With this constitution, inertial mass in a valve system at the time of high speed is reduced, thus an engine speed limit is raisable.
