Abstract
A method can include: providing a connecting rod device disposed inside of a cylinder of an engine, the connecting rod device coupled to a piston head and extending therefrom, the connecting rod device including a variable-length connecting rod and a connecting rod magnet movably coupled to the variable-length connecting rod; and adjusting a length of the connecting rod by supplying a current to pass through a solenoid wrapped around the cylinder, the current passing through the solenoid generating a magnetic field which activates the connecting rod magnet. The activation of the connecting rod magnet can cause an increase or a decrease of the length of the connecting rod.
