DPF waa qalab loogu talagalay in laga saaro walxaha naaftada ama dambaska ka soo baxa gaaska qiiqa ee baabuurta matoorka naaftada. DPF waxay marka hore shaandhaysaa walxaha ka dibna waxay isticmaashaa tignoolajiyada kicinta si ay si joogto ah ugu gubto heerkulka qiiqa caadiga ah ee naaftada.
Shaandheeyayaasha DPF waa hal nooc oo ah monolith-ka socodka derbiga, kanaallada ayaa dhinac ka furan, laakiin dhinaca kale ku xiran. Waxaa lagu rakibi doonaa nidaamka qiiqa baabuurta naaftada, si loo yareeyo walxaha qashinka ah (PM) ee qiiqa ku xayiran. Qaybaha ugu muhiimsan ee qiiqa matoorka naaftada waa walxaha qashinka ah (PM), kaarboon monoksaydh (CO) iyo hydrocarbons (HC), Shaandheeyayaasha walxaha naaftada ah waxay hoos u dhigi karaan 90+% matoorada naaftada.
Horumarintan awgeed, dawladdu waxay haysataa codsi sare oo ku saabsan heerka qiiqa gaaska dabada, sidaa darteed waxaan ku siin karnaa dahaarka DPF, PT, PD, RH sida aad u codsato, caadiyan waa Euro iv v vi.
Dhanka kale, sida suuqa kala duwan uu qabo, waxaan soo saarnaa walxaha cordierite iyo silicon carbide ee aad dooratay, hoos waxaa ku qoran faahfaahinta xogta.
Sifooyinka Fiisikiska & Kiimikada ee Shaandhada Qaybaha Diesel ee Cordierite
Shaandheeyayaasha Cordierite waxay bixiyaan hufnaan shaandhayn oo aad u fiican, waa kuwo aan qaali ahayn (marka la barbardhigo shaandhada socodka derbiga Sic). Khasaaraha ugu weyn ayaa ah in cordierite uu leeyahay dhibic dhalaalid oo hooseeya.

Sifooyinka Fiisikiska & Kiimikada ee Silikoon carbide Shaandhada Qaybaha Diesel
Shaandheeyayaasha walxaha naaftada ee silikoon carbide (shaandheeyayaasha socodka derbiga ee silikoon) waxay leeyihiin dhibic dhalaalid oo ka sarreysa iyo hufnaan shaandhayn (waxay noqon kartaa ilaa 95%) marka loo eego cordierite, badanaa way ka qaalisan yihiin shaandheeyayaasha socodka derbiga ee cordierite.
