Abstract
A method and system for determining a quantity of fuel to be injected into a multi-cylinder, internal combustion engine during each combustion event of the engine includes an air flow sensor for sensing a quantity of air flowing through the engine. An electronic control unit is operative to determine a desired combustion fuel quantity based on the quantity of air flowing through the engine and determine a desired fuel injection quantity based on a previous fuel injection quantity delivered during a previous combustion event and the desired combustion fuel quantity. The control unit is further operative to control the amount of fuel injected into the engine for the current combustion event based on the desired fuel injection quantity.
