Doorashada shaandhada walxaha naaftada ah ee ku habboon (DPF) waxay u baahan tahay in shaandhada lagu waafajiyo nooca saxda ah, nooca, iyo qeexitaannada matoorka ee gaariga, iyadoo la tixgelinayo tayada substrate-ka, dahaarka iyo u hoggaansanaanta sharciyeynta (sida CARB). Mudnaanta sii OEM ama cutubyada ka dambeeya suuqa si loo hubiyo rakibid habboon, rarista birta qaaliga ah ee dib loo warshadeeyay ee ugu habboon iyo cimri dhererka.

Astaamaha:
Iska caabin aad u xooggan oo ku wajahan shoogga kulaylka: iyadoo leh isku-darka ballaarinta kulaylka oo aad u hooseeya, waxay u adkeysan kartaa isbeddellada heerkulka daran inta lagu jiro dib-u-cusboonaysiinta mana aha mid si fudud u dillaacda.
Tiknoolajiyadda qiimaha jaban iyo kuwa qaan-gaarka ah: 30% ~ 50% way ka jaban tahay SiC, waa xalka qaabaynta asalka ah ee ugu weyn ee baabuurta rakaabka iyo gawaarida xamuulka fudud.
Qaab-dhismeedka isku dhafan: si aan kala go 'lahayn, cadaadis hoose oo dhabarka ah, rakibid fudud.
Ku habboon:
Gawaarida naaftada guryaha ee SUV
Gawaarida yaryar ee magaalooyinka iyo basaska (joojinta joogtada ah ee bilawga, xaaladaha hawlgalka oo fudud)
Miisaaniyad xaddidan, raadinta kharash-oolnimo
Astaamaha:
1. Iska caabin heerkul sare leh:ilaa 2700 ℃, kama baqaysid gubasho ama dhalaalid.
2. Kobcinta kulaylka oo aad u dhakhso badan:Kulaylka dib loo soo nooleeyay si siman ayaa loo kala firdhiyaa, iyadoo hufnaan dib u soo kabasho oo sareysa iyo khatarta ka iman karta kulaylka oo yaraata.
3. Xoog sare, cimri dheer oo adeeg ah:u adkaysta xirashada, u adkaysta daxalka, waxaa loo isticmaali karaa 5-8 sano xaaladaha shaqada ee culus.
4. Culeyska kaarboonka sare:waxay kaydin kartaa qiiq kaarboon badan, oo leh muddo dib-u-cusboonaysiin dheer, oo ku habboon culays culus oo muddo dheer ah.
Ku habboon:
Gawaarida xamuulka culus, mashiinnada dhismaha, gawaarida macdan qodista (rarka sare ee muddada dheer, heerkulka sare).
Mashiinno aan waddo lahayn, qalab koronto dhaliya.
Xaalado shaqo oo daran oo leh dib u soo kabasho soo noqnoqda iyo xannibaad fudud oo dambas ah.
