He aha ngā mahi a te hau māori?

Ko te hau māori tētahi o ngā wahie haumaru ake, ka taea te whakamahi mō te whakaputa hiko; ka taea te whakamahi hei rauemi mata matū; ka taea hoki te whakamahi whānuitia i roto i ngā oumu hau ā-iwi me ngā oumu arumoni, ngā whakamahana wai, te whakamahana me te pouaka whakamātao, tae atu ki te hanga pepa, te whakarewa, te keri kohatu, te uku, te karāhe me ētahi atu ahumahi, tae atu ki te tahunga para, te whakamaroke me te whakamaroke.
Koinei te mahi a te hau māori:
1. Ka taea te whakamahi i te hau māori mō te whakaputanga hauHe iti iho te tukunga para o ngā tipu hiko tāpine hau e whakakahangia ana e te hau māori i ērā o ngā tipu hiko waro me te hinu, ā, he nui te whai huatanga o te whakaputa hiko, he iti te utu hanga, ā, he tere te hanga.
2. Ka taea te whakamahi i te hau māori hei rauemi mata matū. He iti ngā painga o te wāhanga whakaputa matū me te hau māori hei rauemi mata, arā, he iti te haumitanga, he iti te whakapaunga pūngao, he iti te whenua e nohoia ana, he iti te kaimahi, he pai te tiaki taiao, ā, he iti hoki te utu whakahaere.
3. He whānuitia te whakamahinga o te hau māori i roto i ngā oumu hau ā-iwi me ngā oumu arumoni, ngā whakamahana wai, te whakamahana me te pouaka whakamātao, tae atu ki te hanga pepa, te whakarewa, te keri kohatu, te uku, te karāhe me ētahi atu ahumahi, tae atu ki te tahunga, te whakamaroke me te whakamaroke.
4. He iti iho ngā tukunga o te hauota waro, ngā waikura hauota me ngā hauwaiwai o ngā waka hau māori i ērā o ngā waka penehīni me te tīhiera. Kāore e kohia te waro, te pakaru me te haehae, ā, he iti rawa ngā utu whakahaere. He waka atawhai taiao ēnei.
He puna pūngao nui te hau māori, ā, he wahie kounga teitei hoki. Ko te wāhanga matua o te hau māori ko te methane, ka taea te whakamahi hei wahie, hei rauemi mata rānei mō te hanga pango waro, te haukini hangai, te methanol, te acetylene, me ētahi atu; he rauemi matū nui te hau māori.
Ki te whakataurite ki te hau māori, LNG kei a ia ngā painga e whai ake nei:
① He watea mō te rokiroki me te kawe;
Ko te mātotoru o te hau māori wai he 625 ngā wā i te mātotoru o te methane i roto i te āhua paerewa. Arā, ka taea te whakapūpū i te 1m3 LNG ki te hau māori 625m3, e whakaatu ana i te ngāwari o te rokiroki me te kawe.
② He pai te haumaru;
Ko te momo matua o te rokiroki me te kawe i te hau māori ko te pēhanga (CNG). Nā te pēhanga teitei o te hau māori kua pēhia, he maha ngā tūponotanga mōrearea ka pā mai.
③ He iti ake te haumi ā-kore;
Ko te kaha o te hau māori kua kōpeketia (CNG) he tata ki te 26% o te penehīni, ko te kaha o te hau māori kua waia (LNG) he tata ki te 72% o te penehīni, he nui ake i te rua o te kaha o te hau māori kua kōpeketia (CNG). Nō reira, he roa te tawhiti o ngā waka e whakamahi ana i te LNG, ā, ka taea te whakaiti i te maha o ngā teihana whakakī waka.
④ Te pānga tino pai o te heu;
Hei wahie mō te hau ā-iwi, mō ngā tipu hiko rānei, ka rerekē tonu te hiahia mō te hau māori, ā, me whakaiti rawa te tuku.
⑤ Te tiaki i te taiao;
Me tino purea te hau māori i mua i te whakarewanga, nō reira he iti iho te nui o te paru i roto i te LNG i tō te CNG, ā, ka puta he āhuatanga mō te tukunga o ngā hauā o te motuka, te whakamahi rānei hei wahie hei whakatutuki i ngā paerewa tino pakari (pēnei i te "Euro II" tae noa ki te "Euro III").
