Abstract
An internal combustion engine which includes an engine block in the shape of a V having a cylinder, a piston reciprocally mounted on the cylinder and a cylinder head having a combustion chamber has a spark plug positioned in the cylinder head at about the axis of the cylinder. In the preferred embodiment two intake valves and two exhaust valves are positioned in the cylinder head for each cylinder with the valve stems extending upwardly from the cylinder and spaced on opposite sides of the spark plug. The two intake and two exhaust valves are opened by a single camshaft positioned above the cylinder head. A push rod means, a first cam follower means, a second cam follower means and a rocker arm means are positioned in the cylinder head to open each intake and exhaust valves. In one form of the preferred embodiment the single camshaft is positioned adjacent the intake valve stem offset towards the center of the V. In another form of the preferred embodiment valve end space adjacent means are provided for each valve and in still another form of the preferred embodiment the valve end space adjacent means include hydraulic tappet means. An alternative embodiment utilizes only one intake and one exhaust valve for each cylinder.
