IC motor has two opposing cylinders to take opposing pistons, with the drive from the piston connecting rods transmitted to crankshafts with a synchronizing cogwheel gearing

摘要

The internal combustion motor has two opposing pistons in cylinders, in a four-stroke action. The drive transmission from the two pistons is through their individual connecting rods on two crankshafts. The two crankshafts are linked together by cogwheels as a synchronizing gearing for the two pistons.
