Abstract
Methods and systems are provided for addressing cylinder pre-ignition. Each cylinder of an engine may be operated in either a split injection mode or a single injection mode based on the pre-ignition history of the cylinder. The timing and number of injections in the split injection mode is adjusted based on the pre-ignition count of the cylinder.
