DPF ndi chipangizo chopangidwa kuti chichotse tinthu tating'onoting'ono ta dizilo kapena soti kuchokera ku mpweya wotulutsa utsi wa magalimoto a injini ya dizilo. Ma DPF amasefa kaye kuti agwire tinthu tating'onoting'ono kenako amagwiritsa ntchito ukadaulo wothandiza kuti azitenthe nthawi zonse kutentha kwabwinobwino kwa utsi wotulutsa utsi wa dizilo.
Ma DPF Filters ndi mtundu umodzi wa monolith yoyenda pakhoma, njira zake zimakhala zotseguka mbali imodzi, koma zimalumikizidwa mbali inayo. Zidzayikidwa mu dongosolo la utsi wa galimoto ya dizilo, kuti zichepetse tinthu tating'onoting'ono (PM) tomwe timatuluka chifukwa cha kutsekeredwa. Zigawo zazikulu za utsi wa injini ya dizilo ndi tinthu tating'onoting'ono (PM), carbon monoxide (CO) ndi hydrocarbons (HC), Ma Dizilo Particulate Filters Angachepetse ndi 90+% kuchokera ku injini ya dizilo.
Ndi chitukukochi, boma lili ndi pempho lalikulu la muyezo wotulutsa mpweya wam'mbuyo, kuti tithe kupereka DPF, PT, PD, RH monga momwe mukufunira, nthawi zambiri ndi Euro iv v vi.
Pakadali pano, malinga ndi msika wosiyanasiyana, timapanga zinthu zopangidwa ndi cordierite ndi silicon carbide zomwe mungasankhe, pansipa pali zambiri zomwe zafotokozedwa.
Katundu Wathupi ndi Wamankhwala a Cordierite Diesel Particleculate Filter
Zosefera za Cordierite zimapereka mphamvu yabwino kwambiri yosefera, ndizotsika mtengo (poyerekeza ndi fyuluta ya Sic wall flow). Vuto lalikulu ndilakuti cordierite ili ndi malo otsika osungunuka.
