1. A connecting rod for an engine, the engine having a piston and a crankshaft, the connecting rod comprising:
a first connecting rod portion coupled to the crankshaft; a second connecting rod portion coupled to the piston, wherein the second connecting rod portion is adapted to move with respect to the first connecting rod portion; a compressible fluid contained in an internal volume, the compressible fluid adapted to vary a length of the connecting rod such that the length of the connecting rod decreases based on a compression of the compressible fluid, and such that the length of the connecting rod increases based on an expansion of the compressible fluid; and at least one limit stop adapted to restrict a movement of the second connecting portion beyond a predefined limit; wherein the connecting rod is adapted to passively vary a compression ratio of the engine based on the variation in the length of the connecting rod. |
