An actuator coupled to the assembly;
The actuator Ri operably der to control the operation of the assembly defines a substantially linear movement of the copying point along the cylinder chamber axis,
An internal combustion engine , wherein the assembly comprises a three-bar rotary mechanism including a piston lever-link-bar, a fulcrum-link bar, and a force-link bar .

The internal combustion engine of claim 1, wherein the assembly is coupled to the internal combustion engine at a point of attachment.

The internal combustion engine of claim 1, wherein the actuator comprises a linear actuator.

The three-bar rotating mechanism,
A first hinge joint connecting a first end of the fulcrum-link bar in a rotatably coupled manner to the internal combustion engine;
A second hinge joint connecting a second end of the fulcrum-link bar and a first end of the piston lever-link-bar;
A third hinged joint connecting the actuator to a first end of the force-link bar; and a second end of the force-link bar and a location on the piston lever-link-bar. The internal combustion engine of claim 1 , wherein the internal combustion engine is configured and positioned by a connecting fourth hinged joint.

A guide element configured in the internal combustion engine and movable in a curved guide coupled to the three-bar rotation mechanism, wherein the movement of the guide element is such that the movement of the copy point is substantially linear; The internal combustion engine of claim 1 , wherein the internal combustion engine is defined by an arc while in the shape.

The internal combustion engine of claim 1, wherein the actuator comprises an electromechanical actuator operable independently of the engine shaft.

7. The internal combustion engine of claim 6 , further comprising an electronic engine control unit that operates said electromechanical actuator.

A method of operating a variable stroke reciprocating internal combustion engine, wherein the internal combustion engine includes a piston configured to reciprocate within a cylinder chamber having an engine shaft and an axis, wherein each piston includes a first piston.
