I te haere tonu o te whanaketanga o te hangarau motuka, kua nui ake te hiahia mō ngā pūnaha whakaputa hau whai hua, pono hoki. Ko tētahi otinga pēnei, ko te rawhi whitiki-V, he wāhanga matua i roto i ngā pūnaha Whakaiti Whakaterenga Whakapūmau (SCR) me te Tātari Matūriki Tīhiera (DPF).
ēneiNgā Rawhi V-Band whakarato i tētahi otinga kua whakaritea mō te whakapūmau i ngā wāhanga SCR me DPF, kia mau tonu ai te haumaru i raro i ngā āhuatanga uaua o ngā pūnaha whakaputa hau hou. Mā te hoahoa V-clamp ka tere, ka māmā hoki te tāutanga, he mea nui tēnei mō ngā kaihanga e hiahia ana ki te whakahaere i ngā tukanga whakaputa me te pupuri tonu i ngā paerewa kounga teitei.
Ko tētahi āhuatanga matua o ā mātou rawhi-V ko tōna hototahitanga ki ngā wāhanga matua o te pūnaha whakaputa hau. He mea nui tēnei hototahitanga, nā te mea ka whakarite kia mau pai ngā rawhi i ngā taputapu SCR me te DPF, e whai wāhi nui ana ki te whakaiti i ngā tukunga kino. Mā te whakarato i tētahi hononga haumaru, ka āwhina ā mātou rawhi-V ki te ārai i ngā turuturu ka whakararu i te whai huatanga o te pūnaha maimoatanga i muri mai. Ehara i te mea ka āwhina noa tēnei ki te whakatutuki i ngā ture tukunga engari ka whai wāhi hoki ki te mahi whānui o te waka.
Kāore e taea te whakanui rawa i te hiranga o tētahi pūnaha maimoatanga whai muri i te mahi pai. I te mea kei te whanake haere ngā waka, kei te piki haere te hiahia mō ngā hangarau whakahaere tukunga whai hua. Hei tauira, ka whakamahia e te pūnaha Selective Catalytic Reduction (SCR) he otinga urea hei huri i ngā waikura hauota kino (NOx) hei hauota me te kohu wai kore kino. I taua wā, ka hopukina, ka rongoatia hoki e te pūnaha Diesel Particulate Filter (DPF) te pungarehu mai i te hauā, kia kore ai e tukuna ki te hau.
Hei tāpiri atu ki tēnā, he pakari, he pono hoki ā mātou rawhi-V, ā, ka taea e rātou te tu atu ki ngā pāmahana me ngā pēhanga teitei e kitea ana i roto i ngā pūnaha whakaputa hau. He mea nui tēnei pakari mō te pupuri i te pumau o te pūnaha whakaputa hau mō te wā roa, hei āwhina i te whakaiti i te tūponotanga o te pakaru me ngā whakatikatika, ngā whakakapinga utu nui. Mā te haumi ki ngā rawhi-V kounga teitei, ka taea e ngā kaihanga te whakaroa i te roa o te ora o ā rātou pūnaha maimoatanga i muri mai, ā, ka pai ake te mahi me te whakaiti i ngā utu tiaki.
Haunga ō rātou painga mahi, ka whakapai ake hoki ā mātou rawhi-V i te pai o te pūnaha whakaputa hau. Ka mahi pai ngā pūnaha SCR me DPF kua tiakina pai, ka whakaitihia ngā tukunga me te whakanui ake i te mahi. Mā te whakamahi i ā mātou rawhi-V, ka taea e ngā kaihanga te whakarite kia tutuki ā rātou waka i ngā paerewa ture, engari ka tukuna hoki he mahi tino pai i runga i te rori.
I roto i ngā kupu poto, ka mau tonu i a rātou ngā wāhanga nui pēnei i te SCR me te DPF, ka waiho hei wāhanga nui o tētahi pūnaha whakaputa hau hou. Mā te whiriwhiri i ā mātou rawhi-V, ka taea e ngā kaihanga te whakapai ake i te pai o te waka, te mahi, me te pono, me te whakarite kia tutukihia ngā ture tukunga kaha, me te whakarato hoki i tētahi wheako taraiwa tino pai. I te whanaketanga tonu o te umanga motuka, ko te haumi ki ngā wāhanga kounga teitei pēnei i te rawhi-V te mea nui ki te noho ki mua i te ara.
