Abstract
An engine control system establishes the injection amount of fuel based on a predicted amount of intake air at the end of an intake stroke based on a rate of change in the amounts of intake air between previous and current periods. An ignition time is based on an actual amount of intake air detected after the end of the intake stroke.
