ABSTRACT:
Methods and devices for determining and putting in fuel into an internal combustion engine on the basis of an air-fuel ratio in proximity to the stechiometric value, based on the use of the ion current released by a device, positioned on each cylinder of said engine. This ion current is acquired by a Control Unit equipped by means, preferably electronic ones, which implement the invention, repeated continually for each engine cycle and for each cylinder, characterized in that the method develops over various phases.
