摘要： The present invention relates to an electromechanical device for incorporation into the design and manufacture of internal combustion engines, which comprises the joining of two specific mechanisms, the first being an elaborate mechanism, called the cam actuator, which makes it possible, through the movement of these cams, to alter, under the control of an electronic control unit, the relative position of the crankshaft with respect to the top dead center of the pistons, inside the cylinder, increasing or decreasing the compression ratio according to the requirements of the engine. The second mechanism is the rotational coupler, formed by an internally-toothed gear, the ring gear, and a shaft with external gear teeth, the sprocket, to be applied at one or both ends of the crankshaft of the engines.

摘要： A variable compression ratio device is configured to be incorporated into an internal combustion engine. The internal combustion engine includes one or more cylinders housing pistons that are coupled to a crankshaft. The variable compression ratio device includes a rotation coupler assembly formed by gears that have internal and external teeth, the rotation coupler assembly being disposed at a distal end of the crankshaft to cause the crankshaft to rotate. Translation variations of the crankshaft are to be converted into rotation and transmitted to at least one of a toothed gear or a flange of a flywheel.

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.
