An internal combustion engine of uniquely simple elements that combines the use of an assemblage of rotating elements to restrain cylinders radically coplanar perpendicular to centerline of the power shaft and pistons and connecting rods to a rotating coplanar reciprocating alignment with the cylinders, channels to force strokes of the pistons and connecting rods, with the energy of the power stroke and the resistance of the same by the channels producing a force that rotates the assemblage inside a ported engine housing. Engine should be lighter, able to use a variety of fuels, able to use simplified ignition systems, produce more power and be more cost efficient to manufacture and operate than existing engines of the same displacement. Once engine position and fuel is decided elements of the fuel, cooling, lubrication, ignition and electrical systems can be included in the drawings.
