ABSTRACT:
An internal combustion engine has a mechanism to control crankshaft axis position and control combustion chamber compression ratio. The mechanism includes control ring, rotatably supporting crankshaft, and rotatably installed in the engine housing. The control shaft is installed in the engine housing and parallel to the crankshaft. The control shaft pinion elements meshing with control ring toothed elements, and rotating control ring, resulting in changing of crankshaft relative position to the cylinder head; this will change engine compression ratio. The crankshaft toothed part constantly meshing with toothed part of the engine output shaft, transferring rotary moving force from crankshaft to engine output shaft.
