ABSTRACT:
An OHC type internal combustion engine with four valves per cylinder in which a single cam shaft extending longitudinally is engaged by individual rocker arms for each valve for pivoting those rocker arms to actuate the valves. The pairs of exhaust valves on one side of the engine are actuated by rocker arms mounted on a continuous rocker arm shaft. The intake valve rocker arms are mounted on a plurality of short shafts supported by their ends. A cam shaft holder is positioned over each cylinder and they serve to rotatably support the cam shaft, support the continuous rocker arm shaft, support the ends of the plural rocker arm short shafts, and to permit access to the spark plug for that cylinder. The spark plug has its electrodes located at the center of the combustion chamber and is inclined outwardly for access from between the intake valve rocker arms for that cylinder.
