ABSTRACT:
A four cylinder four cycle spark ignition engine has oblong pistons each mounted to reciprocate in sliding contact with an oblong cylinder. Intake valves in a series are positioned in a straight line on one side of and parallel to a central plane extending through the longest dimension of each oblong cylinder. Exhaust valves in a series are positioned in a straight line on the other side of and parallel to that central plane. A cam shaft operates all of the intake valves and another cam shaft operates all of the exhaust valves.
