GRVNES DPF tekinoroji inoshandisa porous, wall-flow ceramic kana alloy metal mafirita, anoratidzwa kuva anopisa uye anosimba mukushanda kweinjini.Masefa akaunganidzwa mu modular arrays mukati memitsara yedzimba.Aya modular DPF mafirita anotakurika, kuti agadzirise chidimbu chekudzikisa nyaya kune zvinodiwa neinjini.kuvakwa kwesefa kunopawo hukuru hwekuteya soot uye "kuchengetedza" kugona kupfuura mamwe mafirita.Sefa yekuvandudza tembiricha uye kumashure kumanikidzwa kwakaderera, uye gara zvakanaka mukati meOEM miganhu.
Yakaputirwa nesarufa inodzivirira kudzikisa tembiricha inodiwa kune particulate oxidation, DPF mafirita anobvumira PM kupisa-kudzima kana "passive kudzoreredzwa" vachishandisa injini inopedza kupisa pakupisa kwakadzika se525 ° F/274 ° C, zvichienderana nesoot yeinjini. production.Kusiyana nemamwe mafirita esoot, anogona kudzikamisa NO₂kugadzirwa, zvinoreva kuti hapana kunetseka pamusoro pezvinodzorwa ne-zvigadzirwa.
