METHOD AND DEVICE FOR THE DETERMINATION AND INPUT OF FUEL INTO AN INTERNAL COMBUSTION ENGINE ON THE BASIS OF AN AIR-FUEL RATIO TARGET AND IONIC CURRENT SENSOR

摘要

The invention relates to the field of method 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. The present invention is 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 said method develops over various phases.
