Abstract
A crankshaft may include first and second journals having circular cross-sections, and a crankpin, the crankpin extending between first and second crankpin journals. The crankpin may include first, second, and third cams including respective first, second, and third cam profiles, wherein the first, second, and third cam profiles differ from one another. At least one of the first, second, and third cam profiles may be configured to affect the stroke of a connecting rod coupled to the crankpin. A connecting rod may include first, second, and third followers including respective first, second, and third follower surfaces, wherein the first and second follower surfaces differ from one another. An internal combustion engine may include a crankshaft and a connecting rod configured to provide relative linear movement between a crankpin axis and a proximal end of the connecting rod.
