Method for estimating the sulfur content in the fuel of an internal combustion engine

摘要

A method for estimating the sulfur content in the fuel of an internal combustion engine equipped with a catalyser; the percentage of sulfur present in the fuel supplied during a specific measurement time interval is estimated by dividing the quantity of sulfur stored in the catalyser during the measurement time interval by the product of a fixed conversion constant and the mass of fuel supplied to the cylinder in the measurement time interval.
