I-DPF iyithuluzi elenzelwe ukususa izinto eziphuma kudizili noma umswane egesini yokukhipha umoya yezimoto zenjini yedizili. Izihlungi ze-DPF ziqala ngokubamba izinhlayiya bese zisebenzisa ubuchwepheshe bokusheshisa ukuze zishiswe njalo emazingeni okushisa avamile okukhipha umoya ophumayo osebenza kudizili.
Izihlungi ze-DPF ziwuhlobo olulodwa lwe-monolith yokugeleza kodonga, iziteshi zivulekile kolunye uhlangothi, kodwa zixhunywe kolunye. Zizofakwa ohlelweni lokukhipha umoya lwemoto yedizili, ukuze kuncishiswe izinto ezincane (PM) zokukhipha umoya ngenxa yokubanjwa. Izingxenye eziyinhloko zokukhipha umoya kwenjini yedizili yizinto ezincane (PM), i-carbon monoxide (CO) kanye nama-hydrocarbon (HC), izihlungi ze-Diesel Particulate Zingazinciphisa ngo-90+% ezivela ezinjinini zedizili.
Njengoba intuthuko iqhubeka, uhulumeni unesicelo esiphezulu sezinga lokukhishwa kwegesi ngemuva, ukuze sikwazi ukuhlinzeka nge-DPF, PT, PD, RH ngokwesicelo sakho, ngokwejwayelekile yi-Euro iv v vi.
Okwamanje, ngokwemakethe ehlukene, sikhiqiza izinto ze-cordierite kanye ne-silicon carbide ozikhethele zona, ngezansi kunemininingwane eningiliziwe.
Izakhiwo Zomzimba Nezamakhemikhali Zesihlungi Se-Cordierite Diesel Particulate
Izihlungi ze-Cordierite zinikeza ukusebenza kahle kokuhlunga okuhle kakhulu, azibizi kakhulu (uma ziqhathaniswa nesihlungi sokugeleza kodonga lwe-Sic). Inkinga enkulu ukuthi i-cordierite inephuzu eliphansi lokuncibilika.

Izakhiwo Zomzimba Nezamakhemikhali Zesihlungi Se-Silicon Carbide Diesel Particulate
Izihlungi ze-silicon carbide diesel particulate (izihlungi ze-Sic wall flow) zinezinga eliphezulu lokuncibilika kanye nokusebenza kahle kokuhlunga (kungafika ku-95%) kune-cordierite, ngokuvamile zibiza kakhulu kunezihlungi ze-cordierite wall flow.
