O le DPF o se masini ua mamanuina e aveese ai mea e fa'aputu ai le diesel po'o le lefulefu mai le kesi e alu ese ai le ea o ta'avale afi diesel. E muamua ona fa'amamā e le DPF ia mea e alu ese ai le ea ona fa'aaoga lea o se tekinolosi fa'asolo e fa'aauau ai ona susunuina i le vevela masani o le ea o lo'o fa'agaoioia e le diesel.
O faamama DPF o se tasi ituaiga monolith e tafe i luga o le puipui, e tatala alavai i le tasi itu, ae fa'apipi'i i le isi itu. O le a fa'apipi'iina i totonu o le faiga o le asu o ta'avale diesel, e fa'aitiitia ai mea fa'apena (PM) o le asu e maileia. O vaega autu o le asu o le afi Diesel o mea fa'apena (PM), carbon monoxide (CO) ma hydrocarbons (HC). E mafai e faamama Diesel Particulate ona fa'aitiitia i le 90+% mai afi diesel.
Faatasi ai ma le atinae, ua maualuga atu le talosaga a le malo mo le tulaga faatonuina o le faʻasaʻolotoina o kasa o le siʻusiʻu, ina ia mafai ona matou tuʻuina atu le ufiufi DPF, PT, PD, RH e tusa ai ma lau talosaga, i le tulaga masani o le Euro iv v vi.
I le taimi nei, e tusa ai ma maketi eseese, matou te gaosia mea cordierite ma mea silicon carbide mo lau filifiliga, o loʻo i lalo faʻamatalaga auiliili.
Uiga Fa'aletino ma Fa'akemikolo o le Cordierite Diesel Particulate Filter
E sili ona lelei le fa'amamāina o faamama Cordierite, e taugofie fo'i (pe a fa'atusatusa i le Sic wall flow filter). O le fa'aletonu tele o le maualalo o le tulaga e fa'a'asu ai le cordierite.

Uiga Fa'aletino ma Fa'akemikolo o le Silicon carbide Diesel Particulate Filter
O faamama vaega laiti o le silicon carbide diesel (Sic wall flow filters) e maualuga atu le melting point ma le lelei o le faamamāina (e mafai ona oo atu i le 95%) nai lo le cordierite, e masani lava ona taugata atu nai lo faamama tafe o le cordierite wall.
