MUNDA WA ZOPHUNZITSA
Zomwe zidapangidwa pano zikugwirizana ndi chitsulo chosungunuka chomwe chimagwiritsidwa ntchito pochotsa zosefera zotulutsa mpweya wochokera ku injini za dizilo, zomwe zimatchedwa kuti diesel particulate filters (DPFs), zosefera zosonkhanitsira fumbi kuchokera ku mipweya yoyaka yochokera ku incinerators ndi thermoelectric power plant, zonyamulira chothandizira, zonyamulira zamadzimadzi, etc., fyuluta yopangidwa ngati porous sintered zitsulo, ndi njira kubala porous sintered zitsulo.
ZIMENE ZINACHITIKA
Zisa za uchi zosagwira kutentha zopangidwa ndi zoumba monga cordierite zakhala zikugwiritsidwa ntchito ngati ma DPF. Komabe, zisa za ceramic zimasweka mosavuta ndi kugwedezeka kapena kugwedezeka kwamafuta. Komanso, chifukwa zitsulo zadothi zimakhala ndi matenthedwe otsika, malo otentha amaperekedwa kumaloko chifukwa cha kuyaka kwa carbon-based particulates zomwe zatsekeredwa mu fyuluta, zomwe zimapangitsa kuti fyuluta ya ceramic ikhale yosweka komanso kukokoloka. Chifukwa chake, ma DPF opangidwa ndi zitsulo, omwe ali ndi mphamvu zambiri komanso matenthedwe amatenthedwe kuposa zoumba, aperekedwa.
