DPFMafyuluta ndi mtundu umodzi wa monolith yoyenda pakhoma, njira zake zimakhala zotseguka mbali imodzi, koma zimalumikizidwa mbali inayo. Zidzayikidwa mu dongosolo la utsi wa galimoto ya dizilo, kuti zichepetse tinthu tating'onoting'ono (PM) tomwe timatuluka chifukwa cha kutsekeredwa. Zigawo zazikulu za utsi wa injini ya dizilo ndi tinthu tating'onoting'ono (PM), carbon monoxide (CO) ndi hydrocarbons (HC), Mafyuluta a Tinthu ta Dizilo Amatha kuchepetsa ndi 90+% kuchokera ku injini ya dizilo.

Ngati DPF yakutidwa ndi zitsulo zamtengo wapatali (monga Pt, Pd ndi Rh), utsi wakuda wokhala ndi tinthu ta kaboni kuchokera ku injini ya dizilo umadutsa mu chubu chapadera ndikulowa mu fyuluta. Tinthu ta kaboni timayamwa kupita ku fyuluta yopangidwa ndi ulusi wachitsulo, ikadutsa mkati mwake ndi fyuluta yolimba komanso ngati thumba. Tinthu tating'onoting'ono tikafika pamlingo winawake, choyatsira mchira chimayatsidwa kuti chiziyaka chokha. Pankhaniyi, tinthu tating'onoting'ono timayamwa ndipo timasanduka CO2 yopanda poizoni kenako timatuluka. Chipangizo chonsecho chimapangidwa ngati kapangidwe ka zipinda ziwiri, ndipo kusefa ndi kubwezeretsanso zinthu kumachitika m'malo osiyanasiyana, zomwe zimapangitsa kuti zisasokonezeke. Dongosololi limatha kugwira ntchito lokhalokha momwe injini imagwirira ntchito. Chosefera cha tinthu ta ceramic chopangidwa makamaka ndi uchi, chimagwira ntchito ngati chida chogwira tinthu tating'onoting'ono mpaka pamlingo wina.
