  1. System zum Verringern der Dieselölmenge im Schmieröl eines Dieselmotors eines Kraftfahrzeugs, dessen Abgasleitung (5) mit Reinigungsmitteln (6) versehen ist, denen Regenerationsmittel zugeordnet sind, die Kraftstoffnacheinspritzungen in seine Zylinder ausführen, und bei dem dem Motor (1) außerdem ein Ölbehälter (17) und ein Dieselöl/Öl-Trennkondensator (18), der mit Dieselöldampf-Abführungsmittel (19) versehen ist, zugeordnet sind, mit einer porösen Membran, um flüchtige gerade Kohlenwasserstoffe, die im Öl vorhanden sind, zu beseitigen, dadurch gekennzeichnet, dass die Membran in der Weise angeordnet ist, dass eine ihrer Oberflächen mit dem Ölkreis in Kontakt ist und die andere mit der Luft des Motoreinlasskreises in Kontakt ist, um flüchtige Kohlenwasserstoffe durch die Einlassleitung mitzureißen.
  2. System nach Anspruch 1, dadurch gekennzeichnet, dass es außerdem stromaufseitig von den Trennmitteln einen Abscheider für Submikron-Partikel (21) aufweist.
  3. System nach einem der Ansprüche 1 bis 2, dadurch gekennzeichnet, dass die poröse Membran aus einer Membran des Typs Kohlenstoff, Glas, Keramik und Zeolith gewählt ist.
  4. System nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die poröse Membran mikroporös ist.
  5. System nach Anspruch 4, dadurch gekennzeichnet, dass die poröse Membran einen Poreninnendurchmesser von weniger als 0,5 nm aufweist.
  6. System nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass die poröse Membran auf wenigstens einer ihrer Flächen durch großvolumige Moleküle veredelt ist.
  7. System nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, dass die poröse Membran auf wenigstens einer ihrer Flächen behandelt ist, um ihre Polarität abzuwandeln.
