Abstract
A method for controlling the amount of fuel mixture, including a first and a second fuel of different volumetric energy content, to be supplied to an internal combustion engine determines a desired air fuel ratio for the fuel mixture. The percentage of the first fuel in the fuel mixture is sensed and the desired air fuel ratios for the first and second fuels are determined. The desired air fuel ratio for the fuel mixture is determined as a function of the desired air fuel ratios for the first and second fuels.
