ABSTRACT:
A method for controlling a fuel metering system of an internal combustion engine comprises a step for calculating at least a first increment control value indicative of an increment of fuel supply in accordance with an engine parameter and a second increment control value indicative of an increment of fuel supply in accordance with another engine parameter, and a step for comparing the first and second increment control values and selecting only the larger increment control value for the calculation of the quantity of fuel to be delivered to the engine, so as to prevent the superimposing of two increment control values which would produce an over rich air/fuel mixture.
