DPF chishandiso chakagadzirirwa kubvisa zvinhu zvedhiziri kana soot kubva mugasi rinobuda mumhepo yemotokari dzeinjini yedhiziri. Iyo DPF inosefa inotanga yabata zvinhu zvedhiziri uye yozoshandisa tekinoroji ye catalytic kuti irambe ichipisa pakupisa kwakajairika kwemhepo inobuda mumhepo yedhiziri.
Mafirita eDPF rudzi rumwe rwemonolith inoyerera pamadziro, nzira dzakavhurika kune rumwe rutivi, asi dzakavharirwa kune rumwe. Ichaiswa mudhiziri redhiziri car exhaust system, kuderedza zvinhu zvePM (PM) zveutsi hunobva pakuvharwa. Zvikamu zvikuru zveutsi hweinjini yedhiziri inyaya dzezvinhu (PM), carbon monoxide (CO) uye hydrocarbons (HC), Diesel Particulate Filters Inogona kudzikisa ne90+% kubva kumainjini edhiziri.
Nekuvandudzwa uku, hurumende ine chikumbiro chepamusoro chemuyero wekubuda kwegasi remusana, saka tinogona kupa DPF, PT, PD, RH yekufukidza zvichienderana nechikumbiro chenyu, zvakajairika iEuro iv v vi.
Panguva iyi, zvichienderana nemusika wakasiyana, tinogadzira zvinhu zve cordierite ne silicon carbide zvaunofarira, pazasi pane ruzivo rwakadzama.
Hunhu hwemuviri nemakemikari hweCordierite Diesel Particulate Filter
Mafirita eCordierite anopa kushanda zvakanaka kwekusefa, haadhure zvakanyanya (kana tichienzanisa nefirita yekuyerera kwemadziro eSic). Dambudziko guru nderekuti cordierite ine poindi shoma yekunyunguduka.
