ABSTRACT:
An internal combustion engine system is disclosed that improves regulation of engine speed relative to a speed setpoint. The system controls ignition timing, throttle plate actuation, fuel valve actuation or a combination thereof in accordance with maintaining a setpoint speed. The system also includes a transient air flow estimation for further improving setpoint speed accuracy.
