Abstract
An overhead cam engine with a drive train including a crankshaft, connecting rod, and piston assembly for reciprocating the piston within the cylinder bore of a cylinder block. A cam ring rotates on the same axis as that along which the piston reciprocates, and has lobes on its upper surface for periodically actuating a pair of rocker arms which open and close intake and exhaust valves located within the cylinder head. The cam ring is driven at half speed by the crankshaft through a gear train arrangement including a timing shaft disposed on an axis parallel to the piston axis with gears at both ends for connecting the crankshaft with the cam ring.
