He taputapu te DPF i hangaia hei tango i ngā matūriki tīhiera, i te pungarehu rānei mai i te hau putanga o ngā waka miihini tīhiera. Ka hopukina tuatahitia e ngā tātari DPF ngā matūriki, kātahi ka whakamahia he hangarau whakatere hei tahu tonu i aua matūriki i ngā pāmahana putanga mahi tīhiera noa.
Ko ngā Tātari DPF tētahi momo monolith rere-pā, he tuwhera ngā awa i tētahi taha, engari he mono ki tētahi taha. Ka tāutahia ki roto i te pūnaha putanga hau tīhiera waka, hei whakaiti i ngā matūriki (PM) o te putanga hau e mau ana. Ko ngā wāhanga matua o te putanga hau mīhini tīhiera ko ngā matūriki (PM), te hauota waro (CO) me ngā hauwaiwai (HC). Ka taea e ngā Tātari Matūriki Tīhiera te whakaiti i ēnei mā te 90+% mai i ngā mīhini tīhiera.
Nā te whanaketanga o tēnei, kua nui ake ngā tono a te kāwanatanga mō te paerewa tukunga hau hiku, kia taea ai e mātou te whakarato i te paninga DPF, PT, PD, RH e ai ki tāu tono, ko te tikanga ko Euro iv v vi.
I tēnei wā, e ai ki ngā mākete rerekē, ka hangaia e mātou he rauemi cordierite me he rauemi silicon carbide hei whiriwhiri māu, kei raro nei ngā taipitopito.
Ngā Āhuatanga Ā-tinana me te Matū o te Tātari Matūriki Tīhiera Cordierite
He tino pai te whai huatanga o ngā tātari Cordierite, ā, he iti te utu (ki te whakataurite ki te tātari rere pakitara Sic). Ko te ngoikoretanga nui ko te iti o te ira rewa o te cordierite.

Ngā Āhuatanga Ā-tinana me te Matū o te Tātari Matūriki Diesel Silicon carbide
He teitei ake te ira rewa me te pai o te tātari o ngā tātari matūriki tīhiera silicon carbide (ngā tātari rere pakitara Sic) (tae atu ki te 95%) i te cordierite, he nui ake te utu i ngā tātari rere pakitara cordierite.
