Abstract
A method for estimating the sulfur content in the fuel of an internal combustion engine equipped with a catalyser, using a current sulfur concentration value (S) and a correction of said current sulfur concentration value (S) in order to obtain a new sulfur concentration value (S). The method includes the steps of measuring a first time interval (t-t) which is actually necessary in order to complete a regeneration process to remove sulfur; determining a quantity (SO) of sulfur stored in the catalyser before the regeneration process to remove sulfur using the current sulfur concentration value (S); estimating a second time interval (t-t) which is theoretically necessary to complete the regeneration process, on the basis of the estimated quantity (SO) of sulfur stored in the catalyser; and determining a multiplicative correction coefficient as a ratio between the first time interval (t-t) and the second time interval (t-t).
