He mea hana ka DPF i hoʻolālā ʻia e wehe i nā mea particulate diesel a i ʻole ka soot mai ke kinoea hoʻopau o nā kaʻa mīkini diesel. Hoʻopaʻa mua nā kānana DPF i nā particulates a laila hoʻohana i kahi ʻenehana catalytic e puhi mau iā lākou i nā mahana hoʻopau diesel maʻamau.
ʻO nā kānana DPF kekahi ʻano monolith kahe paia, ua wehe ʻia nā kahawai ma kekahi ʻaoʻao, akā ua pani ʻia ma kekahi. e hoʻokomo ʻia i loko o ka ʻōnaehana hoʻopau kaʻa diesel, e hōʻemi i nā mea particulate (PM) o ka hoʻopau ʻana e ka paʻa. ʻO nā ʻāpana nui o ka hoʻopau ʻenekini Diesel he mea particulate (PM), carbon monoxide (CO) a me hydrocarbons (HC), hiki i nā kānana particulate Diesel ke hōʻemi iā lākou ma 90+% mai nā mīkini diesel.
Me ka hoʻomohala ʻana, ua noi nui ke aupuni no ke kūlana hoʻokuʻu kinoea huelo, no laila hiki iā mākou ke hāʻawi i ka uhi DPF, PT, PD, RH e like me kāu noi, ma ke ʻano maʻamau ʻo Euro iv v vi.
I kēia manawa, e like me ka mākeke like ʻole, hana mākou i nā mea cordierite a me nā mea silicon carbide no kāu koho, aia ma lalo ka ʻikepili kikoʻī.
Nā Waiwai Kino a me Kemika o ka Kānana Particulate Cordierite Diesel
Hāʻawi nā kānana Cordierite i ka pono kānana maikaʻi loa, ʻaʻole pipiʻi ke kumu kūʻai (hoʻohālikelike ʻia me ke kānana kahe pā Sic). ʻO ke keakea nui, ʻo ia ka haʻahaʻa o ka wahi heheʻe o ka cordierite.
