DPFUtwuma duto ni ubwoko bumwe bwa monolith igenda ku rukuta, imiyoboro ifunguye ku ruhande rumwe, ariko irapfundikirwa ku rundi. Tuzashyirwa muri sisitemu yo gusohora imyuka mu modoka ya mazutu, kugira ngo tugabanye ibintu by’imyuka (PM) by’imyuka iva mu modoka ifashwe. Ibice by’ingenzi by’imyuka iva muri moteri ya mazutu ni uduce tw’imyuka (PM), monoxide ya karuboni (CO) na hydrocarbons (HC), Utwuma duto twa mazutu dushobora kugabanya ku kigero cya 90+% bivuye kuri moteri za mazutu.

Iyo DPF itwikiriwe n'icyuma cy'agaciro (nka Pt, Pd na Rh), umwotsi w'umukara ufite uduce twa karubone duturuka muri moteri ya mazutu unyura mu muyoboro wihariye ukinjira muri filter. Uduce twa karubone twinjizwa muri filter ikozwe muri fibre y'icyuma, iyo inyuze mu gice cy'imbere cy'icyuma n'akayunguruzo gasa n'umufuka. Iyo uduce twa karubone tugeze ku rugero runaka, icyuma gitwika inyuma cyashyaga mu buryo bwikora. Muri iki gihe, uduce twakanywe twashyaga tugahinduka CO2 idahumanya hanyuma tugasohora. Igikoresho cyose cyakozwe nk'icyumba cy'ububiri, kandi kuyungurura no kongera gukoresha ibikoresho bigenda ahantu hatandukanye, bigatuma bitabangamirwa. Sisitemu ishobora gukora mu buryo bwikora uko moteri ikora kose. Akayunguruzo k'uduce twa karubone gakozwe cyane cyane mu buki, gakora nk'igikoresho gifata uduce ku rugero runaka.
