An internal combustion engine utilizing a disk-shaped crankshaft operatively connected with respect to at least one pair of opposed pistons. Each piston of each pair is fixedly secured with respect to a shaft extending therebetween. With two pairs of pistons they are arranged at right angles with respect to one another such that each piston fires controlled by a timing device to maintain the rotary crankshaft. The crankshaft can include a gear device or a friction surface device about the external periphery thereof to facilitate distribution of power therefrom. The crankshaft defines an aperture therein within which a crank pin is positioned with an offset connecting arm extending in each opposite direction. The offset connecting arm extends into a bore within which is positioned the rod extending to each pair of pistons. The path of movement of the crank pin is circular to receive driving force from the pistons at selectively timed intervals.
