3. The assembly of claim 1, wherein the substantial part of the secondary connecting rod upper portion is configured to slide inside said controlling member in a reciprocating motion.

4. The assembly of claim 1 , wherein each of the two aligned lateral openings of said controlling member support element comprises a trapezoidal opening with a semicircular cut formed in proximity of a middle point of a base of said trapezoidal opening.

5. The assembly of claim 4, wherein the controlling member support element further comprises a pair of fixing elements each having a trapezoidal shape with a semicircular cut formed in proximity of a middle point of a base of said trapezoidal shape.

6. The assembly of claim 5, wherein two circular openings are formed when the fixing elements are inserted inside said lateral openings of the controlling member support element, wherein the circular openings are configured to receive the pair of aligned lateral pins of said controlling member to form a pair of aligned lateral pin joints.

7. The assembly of claim 6, wherein the circular openings of said controlling member support element and the pair of aligned lateral pin joints of the controlling member are configured to allow for an oscillation of said controlling member.

8. The assembly of claim 1, wherein the piston head, the primary connecting rod, the secondary connecting rod, the controlling member, the controlling member support element, and the crank shaft joint are enclosed in an engine cylinder block.

9. The assembly of claim 8, wherein the controlling member support element further comprises a fixing mechanism configured to affix the controlling member support element inside said engine cylinder block.

10. The assembly of claim 9, wherein said fixing mechanism comprises a bolt configured to be tightened against said engine cylinder block.

11. An engine comprising:

a piston;

a crankshaft; and

a transmission assembly linking the piston to the crankshaft, wherein the transmission assembly comprises:

a pair of primary connecting rods, each with a first opening configured to hingeably connect to said piston;

22 a secondary connecting rod comprising an upper portion and a lower portion, wherein the upper portion comprises an elongated member having a pair of aligned pins, wherein the pair of aligned pins is inserted in second openings of the pair of primary connecting rods to hingeably connect the upper portion to said pair of primary connecting rods;

a controlling member having a pair of opposing guiding rails and a pair of aligned lateral pins, wherein the controlling member is configured to receive a substantial part of the upper portion of said secondary connecting rod, wherein the substantial part of the upper portion of said secondary connecting rod is configured to slide inside said controlling member in a reciprocating motion; and

a controlling member support element configured to enclose the controlling

member within a cylinder block of said engine, the controlling member support element comprising two aligned lateral openings configured to receive the pair of aligned lateral pins of the controlling member, wherein the upper and lower portions of the secondary connecting rod are
