ABSTRACT:
A method for controlling the amount of fuel mixture, including a first and second fuel of different volatility, to be supplied to an internal combustion engine includes calculating a base amount of fuel mixture needed to achieve a desired air to fuel ratio at a predetermined engine operating condition. Such a base amount of fuel mixture is modified as a function of the temperature of the internal combustion engine and is a function of the percentage of the first fuel.
