Abstract

An internal combustion engine includes a cylinder block defining a cylinder and a crankshaft rotatably received by the cylinder block. The crankshaft includes a crankshaft gear and is configured to rotate along a longitudinal axis of the crankshaft. The engine further includes a piston configured to reciprocate within the cylinder between spaced stroke termination points defining a stroke of the piston. The engine also includes a connecting rod operably coupled to the piston. The connecting rod includes a gear configured to engage the crankshaft gear, wherein the crankshaft gear and the gear of the connecting rod are configured to engage one another, such that as the piston travels within the cylinder, the connecting rod rotates the crankshaft via engagement between the crankshaft gear and the gear of the connecting rod.
