ABSTRACT:
A valve-actuating mechanism for an internal combustion engine having two intake valves and one exhaust valve for each cylinder. The two intake valves are on one lateral side of the engine centerline and the exhaust valve and ignition source are on the other side. A cam shaft is disposed along a straight line substantially equidistant from the intake valves and the exhaust valve. Valve-actuating cams are mounted on the cam shaft. Intake rocker arms and exhaust rocker arms are pivotally mounted on the rocker arm shafts supported on the cylinder head and extending in parallel to the cam shaft. At least one of the two intake rocker arms and the exhaust rocker arm are formed to have the same dimensions to make them interchangeable.
