Abstract

The invention relates to an apparatus. The 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 mechanismdisposed 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.

Description

technical field [0001] The present disclosure relates generally to linkages, and more particularly, to magnetically driven variable length linkages and methods of controlling the same. Background technique [0002] A connecting rod is generally referred to as a rigid member that provides the mechanical linkage between a piston and a crank or crankshaft of an engine, particularly a reciprocating engine such as an internal combustion engine. The connecting rod acts as a lever arm to push the piston into and out of the cylinder and convert the linear reciprocating motion of the piston into rotation of the crankshaft. This motion is then transferred to a series of devices capable of powering the engine-equipped machine, such as a vehicle. [0003] A common measure of engine power that depends on connecting rods is the compression ratio, which is defined as the difference between the displacement of a cylinder when the piston is at bottom dead center (BDC) and the displacement o...
