Abstract
Air/fuel ratio of an internal combustion engine is controlled by predicting the air charge to enter the engine two cylinder events into the future and then determining the amount of fuel to be injected to achieve a desired air/fuel ratio. A first fuel pulse is injected, and if needed, a second fuel pulse is injected to achieve the needed amount of fuel for the desired air/fuel ratio.
