ABSTRACT:
An engine with a row of cylinders is provided with two intake ports and intake valves and two exhaust ports and exhaust valves for each cylinder. The intake ports are arranged on one side of a center line of the row of cylinders, adjacent to each other, and side by side in a direction parallel to the cylinder row. The exhaust ports are arranged on another side of the center line, adjacent to each other, and side by side in the direction parallel to the cylinder row so that their centers are located at a distance apart which is larger than a distance at which centers of the intake ports are separated. The cylinder is formed with a "squish" surface between the exhaust ports which provides a squish area between the cylinder head and piston. This produces a squish or compressed flow of the air-fuel mixture to the exhaust ports in the combustion chamber.
