Ukukhetha isihluzi se-diesel particulate (DPF) esifanelekileyo kufuna ukufanisa isihluzi nophawu, imodeli, kunye neenkcukacha zenjini zesithuthi, ngelixa ucinga ngomgangatho we-substrate, ukugquma kunye nokuthobela imithetho (njenge-CARB). Beka phambili ii-OEM okanye iiyunithi ze-aftermarket ezisemgangathweni ophezulu ukuqinisekisa ukufakwa okufanelekileyo, ukulayisha okusemgangathweni kwesinyithi esixabisekileyo esiphinda sisetyenziswe kunye nokuqina.

| Amandla oomatshini | Phakathi | Phezulu (ubulukhuni obusondele kwidayimani) |
| Ulwakhiwo | I-Monolithic (i-ceramic yeqhekeza elinye) | Ihlukaniswe (indibano yeziqwenga ezininzi) |
| Uxinzelelo lomqolo / Ubunzima | Uxinzelelo oluphantsi lomqolo, ubunzima obuphantsi | Uxinzelelo lomqolo oluphezulu kancinci, ubunzima obunzima |
| Umthamo wokulayisha i-Soot | Phakathi | Iphezulu (ingabamba umsi omninzi) |
| Ixabiso | Iphantsi (eyongayo) | Iphezulu (iprimiyamu / umsebenzi onzima) |
| Ukwabelana kwimakethi | Malunga ne-30% | Malunga ne-63% (eqhelekileyo) |
| Ububanzi obungaphandle (mm) | Ubude (mm) | Umqulu (L) | Isicelo esiqhelekileyo |
|---|---|---|---|
| Φ118.4 | 152.4 / 254 | 1.67 / 2.78 | Iilori ezincinci, iiveni ezincinci, oomatshini abancinci |
| Φ144 | 152.4 / 203 / 254 / 305 | 2.49 / 3.31 / 4.13 / 4.96 | Iilori ezincinci, iiveni, iiSUV |
| Φ190.5 | 152.4 / 203 / 254 / 305 | 4.32 / 5.76 / 7.23 / 8.65 | Iilori eziphakathi, iilori ezinzima |
| Φ228 | 152/203/305 | 6.20 / 8.30 / 12.47 | Iilori ezinzima, iibhasi |
| Φ266.7 | 254/305 | 14.2 / 17.1 | Iilori ezinzima, izithuthi zobunjineli |
| Φ300–330 | 300–600 | 21–51 | Oomatshini abanzima, iiseti zejenereyitha |
Iimbonakalo:
Ukumelana okunamandla kakhulu noxinzelelo lobushushu: nge-coefficient ephantsi kakhulu yokwandiswa kobushushu, inokumelana notshintsho olukhulu lobushushu ngexesha lokuvuselelwa kwaye ayiqhekeki lula.
Itekhnoloji ebiza kancinci nevuthiweyo: Ixabiso eliphantsi ngama-30% ~ 50% kuneSiC, sisisombululo esiqhelekileyo soqwalaselo lweemoto zabakhweli kunye neelori ezincinci.
Isakhiwo esidibeneyo: esingenamthungo, uxinzelelo oluphantsi lomqolo, ukufakwa lula.
Ifanelekile kwi:
Iimoto zedizili zasekhaya iiSUV
Iilori ezikhaphukhaphu zasezidolophini kunye neebhasi (indawo yokumisa rhoqo, iimeko zokusebenza eziphantsi)
Uhlahlo-lwabiwo mali olulinganiselweyo, ukufuna ukusebenza kakuhle kweendleko
Iimbonakalo:
1. Ukumelana nobushushu obuphezulu kakhulu:ukuya kuthi ga kwi-2700 ℃, akoyika ukutsha okanye ukunyibilika.
2. Ukuqhuba kobushushu okukhawulezayo kakhulu:Ubushushu obuvuselelweyo busasazwa ngokulinganayo, busebenza kakuhle kakhulu ekuvuseleleni kwaye buncinci umngcipheko wokubaleka kobushushu.
3. Amandla aphezulu, ubomi obude benkonzo:ayigugi, ayidli mhlwa, ingasetyenziswa iminyaka emi-5-8 phantsi kweemeko ezinzima zokusebenza.
4. Umthwalo ophezulu wekhabhoni:inokugcina umsi wekhabhoni omninzi, kunye nexesha elide lokuvuselelwa, elifanelekileyo lomthwalo onzima wexesha elide.
Ifanelekile kwi:
Iilori ezinzima, oomatshini bokwakha, izithuthi zemigodi (umthwalo ophezulu wexesha elide, ubushushu obuphezulu).
Oomatshini abangengabo abendlela, iiseti zejenereyitha.
Iimeko zokusebenza ezinzima kunye nokuvuselelwa rhoqo kunye nokuvaleka lula kothuthu.
