Abstract
A method and system for controlling the injection of fuel across a plurality of fuel injectors coupled together along a fuel rail in an internal combustion engine is provided. The method and system involve producing a reference fuel delivery control signal for each of the fuel injectors as a function of the desired fuel mass to be injected and subsequently adjusting the pulse width of each fuel delivery control signal as a function of the fuel temperature proximate each of the respective fuel injectors. The temperature of the fuel proximate each of the respective fuel injectors along the fuel rail is ascertained by measuring the temperature of the fuel near the inlet of the fuel rail using a temperature sensor and subsequently determining the temperature of the fuel proximate each of the fuel injectors based on the measured fuel temperature measured and the location of said fuel injector along said fuel rail.
