Abstract
An internal combustion engine may include a bushing defining an external circumferential diameter and an aperture defining an internal circumferential diameter. A center defined by the external circumferential diameter and a center defined by the internal circumferential diameter are offset with respect to one another. The internal circumferential diameter is operably coupled to a crankpin, and the external circumferential diameter is operably coupled to a connecting rod, thereby operably coupling the connecting rod to the crankpin. The engine may further include a bushing control assembly, wherein the bushing control assembly is configured to delay initiation of a power stroke of the engine until a crankshaft of the engine has rotated at least about 15 degrees beyond a first stroke termination angle of a compression stroke of the engine.
