ABSTRACT:
A compact four valve per cylinder overhead camshaft valve train arrangement for use with small cylinder bore engines is made possible by the mounting of a single overhead camshaft at a position high over the cylinder head and laterally offset from the cylinder bore centerline and adjacent a rocker arm shaft that is mounted on the cylinder bore centerline diagonally beneath the camshaft and in turn mounts a single forked lever type rocker arm for the simultaneous actuation of two exhaust valves, and a pair of individual axially spaced rocker arms directed to the opposite side of the rocker arm shaft for actuating a pair of intake valves, roller type cam followers being used to reduce friction, the arrangement providing access to the center of the cylinder bore for the mounting of a spark plug below and beneath the rocker arm shaft and between the intake valve rocker arms and the intake valves.
