Abstract
An apparatus can include: a piston head configured to be disposed inside of a cylinder of an engine; a connecting rod device coupled to the piston head and extending therefrom, the connecting rod device including: a variable-length connecting rod including a female component with a hollow body and a male component movably disposed at least partially inside of the female component, the male component configured to be coupled to a crankshaft of the engine, and a connecting rod magnet movably coupled to the female component; and a piston coupling mechanism disposed at least partially inside of the piston head to couple the connecting rod device to the piston head. The connecting rod device can be configured to transition between a coupled state and a de-coupled state.
