ABSTRACT:
A number of embodiments of valve actuating mechanisms for four-cycle engines including a camshaft and a rocker arm actuated by the camshaft for operating an associated poppet valve. The camshaft and rocker arm followers are configured so as to provide an increasing lever ratio on valve opening for effective rapid valve opening and a decreased lever ratio on valve closing so as to avoid valve bounce. Various arrangements of camshafts and rocker arm positions are disclosed.
