Abstract: An improvement to the Waissi type opposed piston internal combustion (IC) engine is proposed. The engine has at least one pair of aligned and opposed cylinders with one reciprocating double-headed piston assembly in each cylinder pair. The reciprocating motion of the piston is transmitted to the driveshaft by a rotating crankdisk, which is off-centered mounted to the driveshaft. The high friction metal to metal contact between the crankdisk and the piston contact wall is replaced by a combination of a roll resistance and friction under hydrodynamic conditions resulting to a significantly reduced total resistance between the piston and the crankdisk. This is accomplished by utilizing a bearing ring assembly slidably installed on the annular perimeter surface of the crankdisk. When the crankdisk rotates the bearing ring is held in its designed place in a slot bounded laterally only by the connecting members of the integrated double-headed piston assembly.
