An internal combustion engine includes a camshaft operably adjusted by a phaser. Another aspect includes an internal combustion engine having an actuation system for an air valve. A further aspect provides a camshaft-in-camshaft system with a cam phaser located adjacent opposite ends. In another aspect, an internal combustion engine apparatus includes multiple nested camshafts with one of the camshafts having a cam configured to actuate an air intake valve associated with a turbulent jet ignition prechamber, and another of the camshafts having a cam configured to actuate an air valve of a main piston combustion chamber, the nested camshafts being independently rotatable by separate electromagnetic actuators.
