A cam system (20) to generate valve actuation in an engine (10) that includes a circular cam lobe (50)
rotated about a first axis (55) is described. The first axis is a preselected distance from the centerpoint
(52) of the circular camlobe. The cam system also includes a cam follower (100) that surrounds the
camlobe and that has an inner oval surface (105) with a major and minor axis. The inner oval surface is
in moving contact with the circular cam lobe during rotation of the cam lobe.
