Abstract
A method and apparatus to operate a spray-guided spark-ignition direct fuel injection internal combustion engine are provided. The invention comprises injecting a first quantity of fuel during a combustion cycle. Spark ignition is initiated, and, injection of a second quantity of fuel is controlled effective to propagate a flame kernel generated by the spark ignition, after the initiation of the spark ignition during the combustion cycle.
