A camless engine operating system that includes an inlet valve switch configured to detect rotational movement of an inlet valve power disc and to output an inlet actuator voltage. A voltage level of the inlet actuator voltage is synchronous with the rotational movement of the inlet valve power disc. An inlet valve is movable to open and close an intake port of a combustion chamber. An inlet valve mechanical force moves the inlet valve to open the intake port. An inlet actuator is configured to exert the inlet valve mechanical force onto the inlet valve. The inlet actuator voltage received by the inlet actuator controls the inlet actuator to exert the inlet valve mechanical force onto the inlet valve.
