Claim 0:
1. A variable compression ratio device configured to be incorporated into an internal combustion engine, the internal combustion engine comprising one or more cylinders housing pistons that are coupled to a crankshaft, 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 the crankshaft to cause the crankshaft to rotate; and
two or more eccentrics configured to cause translation variations of the crankshaft, wherein:
the two or more eccentrics are positioned on trunnions of the crankshaft before and after each connecting rod and respective balances;
the translation variations are to be converted into rotation and transmitted to a toothed gear and to a flange of a flywheel; and
the two or more eccentrics are aligned with corresponding gears to cause changes in translation of a position of the crankshaft in any angle from 0° to 180° responsive to actuation by an electronic control unit that causes a step motor or servomotor to transfer movements of the step motor or the servomotor to a shaft that has a same quantity of intermediate gears as a quantity of the corresponding gears joined to the two or more eccentrics.
