Transmission assembly for an engine

An assembly for an engine configured for linking a piston head to a crankshaft of the engine, the assembly comprising:

• a primary connecting rod configured to hingeably connect to said piston head;
• a secondary connecting rod comprising an upper portion and a lower portion, wherein the upper portion comprises an elongated member having a pin to hingeably connect the upper portion to the primary connecting rod by inserting such pin in an opening of the primary connecting rod,
• 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;
• 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 configured to engage a crank shaft joint between a circular opening formed by a mating of the upper and lower portions of said secondary connecting rod, 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, wherein the controlling member support element further comprises a fixing mechanism configured to affix the controlling member support element to an inside surface of said engine cylinder block.
