Kusarudza firita yedhiziri (DPF) yakakodzera kunoda kufananidza firita nerudzi, modhi, uye marongero chaiwo einjini yemotokari, uku uchifunga nezvemhando ye substrate, coating uye kutevedzera mitemo (yakadai seCARB). Isa OEM kana mayuniti emhando yepamusoro kuti uve nechokwadi chekuiswa kwakakodzera, kurodha simbi inokosha yakadzokororwa zvakanaka uye kugara kwenguva refu.

Zvimiro:
Kuramba kwakasimba kwazvo kukundwa nekupisa: nekuwedzera kwekupisa kwakaderera zvakanyanya, inogona kutsungirira kuchinja kwakanyanya kwekushisa panguva yekugadziriswazve uye haitsemuke nyore.
Tekinoroji inodhura zvishoma uye yekare: yakachipa ne30% ~ 50% pane SiC, ndiyo mhinduro huru yepakutanga yemotokari dzinotakura vanhu nemarori madiki.
Chimiro chakabatanidzwa: chisina musono, kumanikidzwa kwemusana kwakaderera, kuiswa kuri nyore.
Yakakodzera:
Mota dzemotokari dzedhiziri dzemhuri dzeSUV
Marori emumaguta nemabhazi (nzvimbo dzinomira mota nguva nenguva, mamiriro ekushanda ari nyore)
Bhajeti shoma, kutsvaga nzira dzekushandisa mari zvakanaka
Zvimiro:
1. Kudzivirira kupisa kwakanyanya:kusvika 2700 ℃, vasingatyi kutsva kana kunyunguduka.
2. Kupisa kwakanyanya nekukurumidza:Kupisa kunobva kwangogadzirwazve kunopararira zvakaenzana, nekushanda zvakanaka kwazvo kwekugadzirisazve uye njodzi shoma yekupisa inopera.
3. Simba guru, hupenyu hurefu hwebasa:haiparare, haiparare, inogona kushandiswa kwemakore mashanu kusvika masere mumamiriro ezvinhu akaoma ekushanda.
4. Kabhoni yakawanda inorema:inogona kuchengetedza utsi hwakawanda hwekabhoni, ine nguva refu yekuvandudzwa, yakakodzera mutoro unorema kwenguva refu.
Yakakodzera:
Marori makuru, michina yekuvaka, mota dzekuchera migodhi (dzinorema kwenguva refu, tembiricha yakakwira).
Michina isiri yemugwagwa, majenareta.
Mamiriro ekushanda akaomarara ane kudzoreredzwa kwemvura nguva nenguva uye kuvharika kwemadota kuri nyore.
