I-DPF sisixhobo esenzelwe ukususa izinto eziphuma kwidizili okanye umsi kwigesi ephuma kwi-exhaust yezithuthi ze-injini yedizili. Izihluzi ze-DPF ziqala ngokubamba izinto eziphuma kwi-exhaust zize zisebenzise iteknoloji ye-catalytic ukuze zihlale zitshiswa kumaqondo obushushu aqhelekileyo okukhupha i-exhaust kwidizili.
IiFiltha ze-DPF luhlobo olunye lwe-monolith ehamba eludongeni, iitshaneli zivulekile kwelinye icala, kodwa zixhunyiwe kwelinye. Ziza kufakelwa kwinkqubo yokukhupha umoya wemoto yedizili, ukunciphisa izinto ezincinci (PM) zokukhupha umoya ngenxa yokubanjwa. Izinto eziphambili zokukhupha umoya wenjini yedizili zii-particle matter (PM), i-carbon monoxide (CO) kunye nee-hydrocarbons (HC), iiFiltha zeDizili zeParticle zingazinciphisa nge-90+% ezivela kwiinjini zedizili.
Ngophuhliso, urhulumente unesicelo esiphezulu somgangatho wokukhutshwa kwegesi yomsila, ukuze sikwazi ukubonelela nge-DPF, PT, PD, RH ngokwesicelo sakho, ngokwesiqhelo yi-Euro iv v vi.
Okwangoku, ngokwemarike eyahlukileyo, senza izinto ze-cordierite kunye ne-silicon carbide ozikhethileyo, ngezantsi kukho ulwazi oluneenkcukacha.
Iipropati Zomzimba Nezekhemikhali zeCordierite Diesel Particleculate Filter
Izihluzi zeCordierite zibonelela ngokusebenza kakuhle kokuhluza, azibizi kakhulu (xa zithelekiswa nesihluzi sokuhamba kodonga lweSic). Ingxaki enkulu kukuba iCordierite ineqondo lokunyibilika eliphantsi.
