Abstract
A crankshaft for an internal combustion engine may include first and second journals having circular cross-sections, wherein the first and second journals define a longitudinal crankshaft axis. The crankshaft may further include a crankpin defining a longitudinal crankpin axis and being configured to be coupled to a connecting rod, the crankpin extending between the first and second journals, such that the longitudinal crankpin axis is parallel to the longitudinal crankshaft axis. The crankpin may include at least one crankpin journal and at least one cam including a cam profile, wherein the cam profile is configured to affect the stroke of a connecting rod coupled to the crankpin. A connecting rod may include a follower configured to follow a cam. 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.
