Verfahren zur Bestimmung des Kraftstoff-Schwefelgehalts einer Brennkraftmaschine

摘要

A method for estimating the sulfur content in the fuel of an internal combustion engine (1) equipped with a catalyser (11); the percentage (S) of sulfur present in the fuel supplied during a specific measurement time interval is estimated by dividing the quantity of sulfur (SOxstored) stored in the catalyser (11) during the measurement time interval by the product of a fixed conversion constant (KSOx) and the mass of fuel (mfuel) supplied to the cylinder (2) in the measurement time interval.
