ABSTRACT:
A valve mechanism for an intake valve has a cam block including a first cam comprising a base circle and a second cam having a lobe and a base circle the diameter of which is equal to that of the base circle of the first cam. A first rocker arm engaging with the first cam and a second rocker arm engaging with the second cam are provided. The first and second rocker arms are rotatably engaged with each other so as to be independently rocked by corresponding cams, and have holes in which a lock pin engages to connect the first and second rocker arms with each other so as to be rocked together by the second cam. The system is arranged to engage and disengage the pin with and from both the holes of the first and second rocker arms at a time when both the rocker arms engage with the base circles at the same time.
