He taputapu horoi hau maroke, e mōhiotia whānuitia ana ko teTātari Matūriki Tīhiera (DPF)he taputapu matua mō te horoi paoa pango maroke rānei, e whakamahia ana hei tangomatūriki (PM), inā koate pungarehu waro (te paoa pango), mai imīhini whakaputa tīhieraputanga hau. Ka mahi mā te tātari ā-tinana, kāore e whakawhirinaki ki tētahi tāpiringa wai, nō reira te kupu "maroke".
I. Mātāpono Mahi: Te Tātari ā-tinana me te Whakaora Anō
Ka taea te whakarapopoto i tōna kaupapa mahi hei tukanga e toru:"Hopu - Kohikohi - Whakaora anō."
- Hopu (Tātari):
- Ka tomo te hau putanga pāmahana teitei mai i te mīhini ki te pūmārō, ka rere mā roto i tētahi huānga tātari i hangaia ki te uku porous (hei tauira, cordierite, silicon carbide) te konganuku kua whakakāhia rānei.
- Kua kapi ngā pakitara o te huānga tātari i ngā pore iti (he iti iho i te 1 micron te rahi), e āhei ai ngā hau (hei tauira, te hauota, te hauhā waro, te mamaoa wai) kia puta engari kia nui ake te mau.ngā matūriki totoka (ngā pungarehu, te pungarehu) me ngā wāhanga waro wairewa (SOF)i roto, i runga rānei i te mata o te tātari.
- Whakaemi:
- Ka āta hanga ake ngā matūriki kua mau ki roto i te tātari, ka hanga he "keke pungarehu." I te piki haere o te kohikohinga, ka āta piki ake te pēhanga hoki o te putanga hau.
- Whakaora anō:
- Ina tae te pēhanga whakamuri o te putanga hau ki tētahi rohe kua whakaritea (ka pā ki te mahi a te miihini), me tīmata te pūnaha"whakaoranga anō"te tukanga hei tahu i te pungarehu kua kohia i roto i te tātari, kia whakahokia mai ai tōna kaha tātari.
- Ko te whakaoranga te tukanga matua, ka tutukihia mā te:
- Whakahoutanga ĀhuakoreIna mahi te mīhini whakaputa hiko i raro i te kawenga nui, ka piki ake te pāmahana o te putanga hau (te tikanga >350°C). Ka tauhohe te pungarehu kua mau ki ngā waikura hauota (NO₂) i roto i te hau putanga hau, ā, ka waikura (ka āta tahuna). He mahi tonu tēnei engari kāore e ranea mō te horoi katoa.
- Whakaora KahaKa tīmatahia mā te kaha ina tino teitei rawa te pēhanga whakamuri, ā, kāore i te rawaka te pāmahana o te putanga hau.
- Āwhina wahie (Mumura)Ka werowerohia he iti noa o te hinu tīhiera ki mua i te DPF, ka tahuna e te mura ahi, ka piki ake te pāmahana hau e tomo ana ki te DPF ki runga ake i te 600°C, ka tere te waikura me te tahunga o te pungarehu.
- Whakahoutanga o te Whakamahana HikoKa whakamahanahia te huānga tātari ki te pūwāhi mura o te pungarehu mā te whakamahi i ngā huānga whakamahana hiko.
- Whakahoutanga NgaruitiKa whakamahi i te pūngao ngaruiti hei whakamahana i ngā matūriki pungarehu.
II. Ngā Wāhanga Matua
Ko te pūnaha horoi maroke katoa kei roto i ēnei:
- Huānga Tātari DPFTe wae tātari matua.
- Pūoko Pēhanga Rerekē (Whakarunga/Whakararo)Aroturuki i te rerekētanga pēhanga puta noa i te tātari, whakatau i te taumata kawenga pungarehu, ā, whakaoho i te tohu whakaora.
- Ngā Pūoko PāmahanaAroturukihia te pāmahana o te tomokanga/putanga hei whakahaere i te tukanga whakahou me te ārai i te kino o te wera nui.
- Pūnaha Whakaoho me te Whakahaere: Ka whakahaere aunoa i te tīmatanga me te mutunga o te kaupapa whakaora anō i runga i ngā tohu mai i ngā pūoko pēhanga me te pāmahana.
- Kaiwhakaoho WhakaoraPērā i te werohanga tīhiera, te mura, te taputapu whakamahana hiko, me ētahi atu.
- Whare me te Papa WhakamarumaruHei pupuri i te pehanga me te wera.
III. Ngā Painga me ngā Huakore
| Ngā Painga | Ngā ngoikoretanga |
| Te Tino Pai o te Tango PuehuHe tino teitei te pai o te tātari mō te pungarehu (paoa pango), ka eke ki te >95%, ka whakaiti i te pango o Ringelmann ki te taumata 0-1. | Ka whakanui ake i te pēhanga whakamuri: Ka pā ki te pai o te manawa o te mīhini, ka piki ake pea te whakapaunga wahie (tata ki te 1-3%). |
| Kāore e hiahiatia he wai e pau anaKāore i rite ki te SCR (e hiahiatia ana he urea), ko te hiko me te iti noa o te hinu tīhiera e hiahiatia ana hei whakaora i te wā e whakamahia ana, ā, kāore he utu tāpiri mō te whakapaunga. | Te Tiaki UauaMe horoi te pungarehu i ia wā (te tango i te pungarehu kore e mura) me te tirotiro. Ki te kore e taea te whakahou, ka ārai, ka rewa rānei te tātari. |
| Hanganga KiatoHe tino māmā te pūnaha, he iti noa te rahi, ā, he ngāwari hoki te tāuta. | He tairongo ki te kounga o te wahieKo te nui o te whanariki i roto i te tīhiera ka puta he whanariki, ā, ko te nui o te pungarehu ka tere ake te aukati i te tātari, ka pā kino ki te roa o te ora me te mahi. |
| Ngā Whāinga Matua mō te PirimiaKo te taputapu tino tika me te tino whai hua mō te whakaoti i te paoa pango e kitea ana me ngā matūriki. | Kāore e rongoā i te NOxKo ngā matūriki te kaupapa matua; he iti noa te pānga ki ngā waikura hauota. Me whakakotahi me te pūnaha SCR kia tutuki ai ngā whakaritenga katoa. |
| He pai mō te mahi wā potoKi te whakatauritea ki te SCR e hiahia ana ki ngā āhuatanga pāmahana pumau, he pai ake te urutau o te DPF ki ngā huringa mahi rerekē. | Te Pūtea Tuatahi TeiteiIna koa mō ngā pūwhakamātautau e whakamahia ana i runga i ngā huinga whakaputa hiko kaha-tiketike. |
IV. Ngā Horopaki Taupānga Matua
- Ngā Wāhi me ngā Whakaritenga Tukunga Tino KahaHe hiko tārua mō ngā pokapū raraunga, ngā hōhipera, ngā hōtēra papai, ngā whare tari, me ētahi atu, hei ārai i te parahanga o te paowa pango.
- Ngā Tāone me ngā Rohe Taupori KikīHei whakatutuki i ngā ture taiao ā-rohe, hei karo hoki i ngā amuamu.
- Ngā Huinga Hīkoi Kua Tāutahia ki RotoHe mea nui mō te pure i te hau hau kia pai ai te kounga o te hau o roto me te haumaru o te pūnaha hauhautanga.
- Ngā Ahumahi MotuhakeNgā teihana whakawhitiwhiti kōrero, te keri whenua (momo ātete-pahū), ngā kaipuke, ngā tauranga, me ētahi atu.
- Hei Wāhanga o tētahi Pūnaha WhakakotahiKua whakauruhia ki te SCR (mō te denitrification) me te DOC (Diesel Oxidation Catalyst) hei whakatutuki i ngā paerewa tukunga ā-Motu IV/V, teitei ake rānei.
V. Ngā Whakaaro Hira
- Wahie me te Hinu MīhiniMe whakamahitīhiera iti-whanariki(he pai ake mēnā he iti iho i te 10ppm te ihirangi whanariki) mehinu miihini iti-punga (tohu CJ-4, teitei ake rānei)Ko te nui o te whanariki me te pungarehu ngā tino take o te paihana DPF, te aukati, me te poto o te roa o te ora.
- Ngā Tikanga WhakahaereĀraia te whakahaere roa o te huinga whakaputa hiko i ngā kawenga tino iti. Ka hua ake tēnei i te pāmahana iti o te putanga hau, ka ārai i te whakahoutanga kore mahi, ā, ka puta ai ngā whakahoutanga auau, nui te kaha e hiahiatia ana.
- Aroturuki me te Tiaki:
- Aroturuki tatate pēhanga whakamuri o te putanga haumengā rama tohu whakaora.
- Mahi auauratonga horoi pungarehu ngaio(te whakamahi i te hau kōpeke, i ngā taputapu horoi motuhake rānei) hei tango i te pungarehu whakarewa (konupūmā, konutea, whākōkī, me ētahi atu).
- Te whakatū i ngā tuhinga tiaki, te tuhi i te auau o te whakahoutanga me ngā huringa pēhanga whakamuri.
- Te Whakataurite PūnahaMe whiriwhiri te pūwhakamāori, me te whakataurite hoki i runga i te tauira motuhake o te huinga whakaputa hiko, te nekehanga, te mana whakatauranga, me te tere rere o te hau. Ka pā kino te whakataurite hē ki te mahi me te roa o te ora o te miihini.
- HaumaruI te wā e whakahoutia ana, he tino teitei te pāmahana o te whare horoi. He mea nui te whakamarumaru wera tika, ngā tohu whakatūpato, me te noho tawhiti atu i ngā rauemi mura.
Whakarāpopototanga
Ko te pūwhakamātautau hau maroke (DPF) hehangarau tino whai hua, rongonuimō te whakaoti rapangate paoa pango e kitea ana me te parahanga matūrikimai ingā huinga whakaputa hiko tīhieraKa hopukina e ia te pungarehu waro mā te tātari ā-tinana, ā, ka mahi ā-hurihuri mā te whakahoutanga pāmahana teitei. Ko tōna angitu o te whakamahinga e whakawhirinaki ana kite rahi tika, te kounga wahie pai, ngā āhuatanga whakahaere tika o te whakaputa hiko, me te tiaki auau pakariI te wā e whiriwhiri ana, e whakamahi ana hoki i te DPF, me whakaaro he wāhanga nui o te pūnaha huinga miihini-whakaputa hiko whānui.
