An internal combustion engine which includes two parallel crankshafts positioned in crankcases, a cylinder positioned on a side of the crankcases, a piston movably disposed within the cylinder, and connecting rods linked to the piston and extending from respective crankshafts. Positions at which the two connecting rods are linked to the piston and the crankshafts are constantly kept symmetrical with respect to a cylinder axis when the two crankshafts rotate in opposite directions.
