A technique for controlling air-fuel ratio in an internal combustion engine consuming more than one fuel type includes determining a target air-fuel ratio as a function of engine operating conditions; determining an actual air-fuel ratio from the engine operating conditions; determining a first fuel quantity of a first fuel to introduce into a combustion chamber as a function of the engine operating conditions; determining a second fuel quantity of a second fuel such that the actual air-fuel ratio equals the target air-fuel ratio to within a predetermined range of tolerance when the first fuel quantity and the second fuel quantity are introduced into the combustion chamber, the second fuel quantity being determined as a function of the engine operating conditions, the target air-fuel ratio, the actual air-fuel ratio and the first fuel quantity; and introducing the first fuel quantity and the second fuel quantity into the combustion chamber.
