An internal combustion engine comprises multiple cylinder blocks in series rotatablely mounted in a single casing. The cylinder blocks each define multiple cylinders along a circumferential portion of the cylinder block to receive a piston in each one. The casing forms multiple spark plug holes and defines multiple exhaust ports and multiple intake ports in the periphery thereof. Each the cylinders is accessible to the spark plugs, the exhaust ports and the intake ports upon rotation of the cylinder block. The spark plugs, the exhaust ports and the intake ports of various cylinder blocks are staggered.
