Abstract

Fremgangsmåte og anordning for redusering av emisjon av partikler fra dieselmotorer. Eksos går gjennom et dieselpartikkelfilter som har minst to trinn innbefattende (a) et katalysatoravsnitt med en platinagruppemetallkatalysator på kontaktoverflater i katalysatoravsnittet og (b) et filteravsnitt med passasjer som kan fjerne partikler fra en strøm av forbrenningsgasser som oppstår ved forbrenningen av brenselet i motoren og kan holde dem der for å tillate deres oksidering. Karbonfjerningen fremmes ved å bruke nivåer av platinagnippemetallsammensetning, ceriumsammensetninger, brensel og/eller eventuelle kjemiske forsterkere for generering av N0i katalysatoravsnittet i mengder som er tilstrekkelige til å danne ceriumnitrater i filteravsnittet. Ceriumoksid assosieres med og holder dispergeringen av platina i filteravsnittet og ceriumnitratene er tilgjengelige på overflaten og inne i sotpartiklene for derved å muliggjøre økt sotoksidering ved et lavere balansepunkt.
