DPFMafirita imhando imwe yemadziro anoyerera nemhepo, nzira dzacho 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

Kana DPF yakafukidzwa nesimbi inokosha (yakadai sePt, Pd neRh), utsi hutema hune kabhoni kubva muinjini yedhiziri hunopfuura nemuchubhu chaiyo huchipinda mufirita. Kabhoni inonyudzwa mufirita yakagadzirwa nefiber felt yesimbi, kana ichipfuura nemukati meseti yakakora uye firita yebhegi. Kana kunyudzwa kwezvikamu kukasvika padanho rakati, chitofu chemuswe chinobatidzwa kuti chitsve chega. Muchiitiko ichi, zvikamu zvinonyudzwa zvinopiswa zvoshandurwa kuita CO2 isina chepfu zvobva zvaburitswa. Mudziyo wose wakagadzirwa sechivakwa chemakamuri maviri, uye kusefa nekudzokorodza zviri kuitwa munzvimbo dzakasiyana, zvichiita kuti zvisakanganiswa. Sisitimu inogona kushanda yega chero mamiriro ekushanda ari muinjini. Yakagadzirwa zvakanyanya sehoneycomb ceramic particulate filter, inoshanda semudziyo unobata zvikamu kusvika padanho rakati.
