Abstract

Die Erfindung betrifft ein Verfahren zur Bestimmung einer Zusammensetzung eines Kraftstoffgemischs (116), insbesondere zur Bestimmung eines Ethanolanteils und/oder eines Wasseranteils in dem Kraftstoffgemisch (116). Es wird eine erste Mikrowellen-Strahlung mit mindestens zwei Mikrowellenfrequenzen in das Kraftstoffgemisch (116) eingestrahlt und mindestens eine zweite Mikrowellenstrahlung aus dem Kraftstoffgemisch (116) empfangen. Die zweite Mikrowellenstrahlung wird mit der ersten Mikrowellenstrahlung verglichen und mindestens eine Kenngröße in Abhängigkeit von der Mikrowellenfrequenz der ersten Mikrowellenstrahlung bestimmt. Aus dem Verlauf der Kenngröße über die Mikrowellenfrequenz der ersten Mikrowellenstrahlung wird auf die Zusammensetzung des Kraftstoffgemischs (116) geschlossen.
