Pātene Wehenga Utaina Ngaohiko-Tiketike Rukuhia ki te Hinu

He rite te kaupapa mahi o te pana kawenga ngaohiko teitei ki te pana o te ara iahiko. I te nuinga o te wā, ka tāutahia he taputapu tinei pewa māmā, engari he tino māmā tōna hanganga. E whakaatu ana te pikitia i tētahi pana kawenga ngaohiko teitei hau pēhi. Ko tana tukanga mahi: ina whakatuwheratia te parai, i raro i te mahi a te puna whakatuwhera, ka huri te rakau matua ki te taha matau. I tetahi taha, ka neke ake te piston mā te pūnaha crank-slider hei pēhi i te hau; I tetahi taha, mā te pūnaha tuku e rua ngā huinga hononga wha-pae, ka whakatuwheratia tuatahitia te maripi matua, kātahi ka panaia te maripi tinei pewa hei whakatuwhera i te hononga pewa, ā, ka pupuhi te hau pēhi i roto i te rango i te pewa mā te pūwero. I te wā e kati ana, mā te rakau matua me te pūnaha tuku, ka huri te mata matua me te mata tinei pewa ki te taha matau i te wā kotahi, ā, ka kati tuatahitia te hononga pewa; ka huri tonu te rakau matua, kia kati ai te hononga matua i muri mai. I te wā e kati ana, ka rongoa te puna whakatuwhera i te pūngao i te wā kotahi. Nā te mea kāore e taea e te pana kawenga te wawahi i te iahiko poto-arahiko, ka whakamahia pinepinetia me te fiusi ngaohiko teitei-whakawhāiti-iahiko. E kore e taea e te mahi whakawhāiti-iahiko o te fiusi whakawhāiti-iahiko te whakaoti noa i te mahi wawahi i te arahiko, engari ka whakaiti nui hoki i te wera e puta mai ana i te iahiko poto-arahiko me te mana hiko.

Pānga pana kawenga ngaohiko teitei i rumakina ki te hinu:
Kei roto i te hinu whakawhiti te pana kawenga rumakina-hinu. Ko te pana kawenga he taputapu whakawhiti i waenganui i te kaiwawao hiko me te pana wehe. He taputapu tinei pewa ngāwari tōna, ka taea te tapahi i te ia kawenga kua whakatauria me te ia taumaha, engari kāore e taea te tapahi i te ia ara poto. Ko te pana kawenga rumakina-hinu he pana hononga-wāhanga-toru kua tāutahia ki roto i te whakawhiti whakakotahi, ā, e whakamahi ana i te hinu whakawhiti hei reo whakamahana me te tinei pewa. Ko te hinu whakawhiti he hua wehewehenga o te hinu, ā, ko ōna wāhanga matua ko ngā alkane, ngā hauwaiwai naphthenic kua kukū, ngā hauwaiwai kakara kāore i kukū me ētahi atu matū. E mōhiotia whānuitia ana ko te hinu whakaheke tapawhā, he wai mārama kōwhai mārama, he kiato whanaunga 0.895. Te ira tio <-45 ℃. Whakamahia te kaha o te pewa tonu hei wawahi me te whakakā i te hinu huri noa i te pewa me te whakamatao hei tinei i te pewa. He ngāwari noa te hanganga, engari he nui te taumaha, ā, he pai mō ngā hua o waho o te 35kV me raro iho.
