Abstract
An internal combustion engine operates in an unthrottled condition during HCCI operation while preferred combustion phasing is determined. An EGR mass flow rate is commanded to correspond with the preferred combustion phasing. The EGR valve is controlled to achieve commanded EGR mass flow rate. Position of the throttle valve is controlled to achieve commanded EGR mass flow rate when the commanded EGR mass flow rate exceeds control authority of the EGR valve.
