Abstract
A system and method for controlling fuel delivery through a fuel injection system to an internal combustion engine is described. An engine controller calculates a mass of fuel for delivery to one of the cylinders through one of the fuel injectors, based upon the operation of the internal combustion engine. Gas temperature in the intake runner of the cylinder is determined, and a compensation term is selected based upon the calculated mass of fuel and the determined gas temperature in the intake runner of the cylinder. The calculated mass of fuel is adjusted using the compensation term, and the controller controls open time of the fuel injector based upon the adjusted calculated mass of fuel.
