Abstract: An internal combustion engine includes a camshaft with a lobe rotatable about a camshaft axis and a follower and which follows the lobe and is reciprocated along a follower axis by the lobe. A contact force is generated between the lobe and the follower such that the contact force is cyclic between a minimum contact force and a maximum contact force. The follower axis is offset from the camshaft axis such that the lobe contacts the follower at a contact point that is substantially aligned with the follower axis when the maximum contact force is generated between the lobe and the follower. In this way, the side load on the follower is minimized.
