PROCEDE DE DETERMINATION DE LA TENEUR EN EAU D'UN CARBURANT MIXTE ALCOOL-ESSENCE DANS UN MOTEUR A COMBUSTION INTERNE ET DISPOSITIF POUR SA MISE EN OEUVRE

摘要

Disclosed is a method for determination of the water content of a mixed alcohol/gasoline fuel in an internal combustion engine of a vehicle, which includes the stages of: determination of a first value for alcohol content of the fuel using a measurement of combustion richness; determination of a second value for alcohol content of the fuel using a measurement recorded by a sensor for measurement of the electrical conductivity of the fuel; comparison of the first value and the second value; and, when the first value is lower than the second value, determination of the water content of the fuel by assigning a predetermined value for water content associated with the pair consisting of the first value and of the second value for alcohol content.
