Abstract
An internal combustion engine may include a cylinder block defining a cylinder, and a crankshaft defining a crankpin, wherein the crankshaft is rotatably received by the cylinder block and rotates about a longitudinal axis. The internal combustion engine may further include a piston configured to reciprocate within the cylinder, and a connecting rod operably coupled to the piston and the crankpin. The connecting rod may include a first rod element having a first distal end and a first proximate end, wherein the first distal end is operably coupled to the piston. The connecting rod may further include a second rod element having a second distal end operably coupled to the first proximate end of the first rod element, and a second proximate end operably coupled to the crankpin, wherein the first rod element and the second rod element are pivotally coupled to one another.
