Abstract

Die Erfindung betrifft ein Verfahren zur Abtrennung einer niedersiedenden Kraftstofffraktion aus einem motorischen Kraftstoff an Bord eines Kraftfahrzeugs. Das Verfahren umfaßt die Verfahrensschritte

  • Abpumpen des Kraftstoffbehälters mit einer Gasförderpumpe zur Erzeugung eines Unterdrucks, bei dem die Komponenten der abzutrennenden niedersiedenden Kraftstofffraktion verdampft werden,
  • Kondensation der Komponenten der niedersiedenden Kraftstofffraktion auf der Druckseite der Gasförderpumpe.

The invention relates to a method for separating a low-boiling fuel fraction from a motor fuel on board a motor vehicle. The process comprises the process steps
  • Pumping off the fuel tank with a gas feed pump to generate a negative pressure in which the components of the low-boiling fuel fraction to be separated are evaporated,
  • Condensation of the components of the low-boiling fuel fraction on the pressure side of the gas feed pump.
