Abstract:
An engine control system includes a fuel cutoff (FCO) module, a fuel control module, and a spark control module. The FCO module, when a FCO event is disabled, determines a feed-forward (FF) number of cylinders to offset a delay period associated with supplying fuel to the cylinders of an engine and selectively maintains a FCO torque request at a predetermined torque. The fuel control module commands fuel be supplied to the FF number of cylinders of the engine when the FCO event is disabled. The spark control module maintains a spark timing of the FF number of cylinders at a fully retarded spark timing based on the FCO torque request.
