Abstract: A variable valve timing arrangement for an engine system is disclosed. The variable valve timing arrangement includes a cam follower configured to follow a cam lobe. A pushrod is operably connected with the cam follower and a pushrod rotation mechanism is configured to selectively rotate the pushrod. Further, a cam follower adjustment mechanism is configured to reposition the cam follower based on the rotation of the pushrod.
