Patent ID: 11879400

Abstract:
A variable compression ratio device configured to be incorporated into an internal combustion engine. The internal combustion engine including one or more cylinders housing pistons that are coupled to a crankshaft. The variable compression ratio device including 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. Where 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.
