Abstract
A method for operating a multi-cylinder spark-ignition direct-injection internal combustion engine responsive to a low load demand includes monitoring an engine state associated with combustion for each cylinder during each combustion cycle during low load operation, determining a combustion stability index for each cylinder based upon the monitored engine state associated with combustion for the respective cylinder, and individually adjusting an initiation of a spark discharge relative to an end of a fuel injection event for each cylinder based upon the combustion stability index determined for the respective cylinder.
