Classification: CPC F | IPC F

Claim 7:
8. A variable compression ratio device configured to be incorporated into an internal combustion engine, the variable compression ratio device comprising:
rotation coupler assemblies, formed by gears that have internal and external teeth that are disposed at distal ends of a crankshaft of the internal combustion engine to cause the crankshaft to rotate;
an eccentric actuator configured to cause changes in a relative position of the crankshaft; and
an electronic control unit that is configured to actuate a step motor or servomotor to cause eccentrics of the eccentric actuator to change the relative position of the crankshaft in relation to a top of cylinders of the internal combustion engine to control a compression rate of combustion chambers of the internal combustion engine, wherein a turn of the crankshaft is transferred to a flywheel and a toothed gear via the rotation coupler assemblies belt.
