Verfahren zur Abtrennung einer schwefelarmen Kraftstofffraktion aus einem motorischem Kraftstoff an Bord eines Kraftfahrzeugs

摘要

Low-boiling sulphur-free fuel components, eg butane, are evaporated in the fuel tank KV, eg at ambient temperatures, using the vacuum Psaug produced by the gas delivery pump PU. The outlet of the pump PU is connected to a pressure vessel DG in which the sulphur-free components condense for immediate use. An enrichment of sulphur-containing components takes place in the fuel tank KV.
