Ina me pēhi te hau mai i te pēhanga iti ki te pēhanga tino teitei—hei tauira, mai i te pēhanga hau ki te 300 pae mō te rokiroki hauwai, mai i te 5 pae ki te 250 pae rānei mō te kawe hau māori—he onge te wā pēhitanga kotahi te otinga pai. I te nuinga o te wāngā pūwhakakoi whakawhiti, ko te whakautu he pēhitanga maha-wāhanga: te wehewehe i te pikinga pēhanga katoa kia rua, neke atu rānei ngā taahiraa, me te whakamatao i waenga i ngā wāhanga. E rua ngā painga nui o tēnei whakaritenga ngāwari: ka whakaitihia te mana e hiahiatia ana hei pēhi i te hau, ā, ka tino whakaitihia ngā kaha miihini e pā ana ki ngā wāhanga neke o te pēhitanga.
Mā te mārama ki te āhua o te pēhanga maha-wāhanga e whakatutuki ai i ēnei painga ka āwhina i ngā kaihangarau ki te whiriwhiri i te whirihoranga tika mō ngā tono uaua.
Te Tirohanga Thermodynamic: He iti ake te mahi, he iti iho te pāmahana
Mā te pēhi i te hau ka wera tonu. Ko te mahi e hiahiatia ana hei whakaara ake i te hau mai i te pēhanga iti ki te pēhanga teitei ake e pā tika ana ki te pikinga o te pāmahana. I roto i te pēhitanga kotahi-wāhanga, ka taea e te pāmahana hau te tino teitei—i ētahi wā ka nui ake i te rohe haumaru o ngā hinu whakahinuhinu, ngā mowhiti piston, tae noa ki te hau tonu (he mōrearea kei mura aunoa mō ngā hau mura).
Te pēhitanga maha-wāhangae aro atu ana ki tēnei mā:
- Te pēhi i te hau i te wāhanga anake o te rango tuatahi.
- Te whakamatao i te hau ki te pāmahana tata ki te taiao i roto i te pouaka whakamatao i waenganui i ngā wāhanga.
- Te pēhi anō i roto i ngā rango tuarua (me ngā rango e whai ake nei).
Nā te mea ka uru te hau ki ia wāhanga i te pāmahana iti rawa atu i tērā i roto i te mīhini kotahi-wāhanga, ka tino whakaitihia te mahi pēhitanga mō ia wāhanga. Nō reira, ka iti ake te mahi katoa mō te pikinga pēhanga katoa. Koia te take he pai ake te whai huatanga o ngā pēhitanga maha-wāhanga i roto i te pāmahana mō ngā ōwehenga pēhanga teitei. Ko te iti o te wera e maumauria ana ko te tikanga he iti ake te pūngao e tangohia mai i te motuka, ā, he iti ake ngā utu whakahaere.
Te Tirohanga Ā-Mīhini: Ngā Kaha Hau Iti, Ngā Wāhanga Mama Ake
He rite te kaha hau i runga i te piston ki te rerekētanga pēhanga puta noa i a ia me te horahanga piston. I roto i te compressor kotahi-wāhanga, ka pā tika te pēhanga tukunga whakamutunga ki runga i te piston i te nuinga o te whiu pēhanga, ka hanga he kaha hau tino teitei. Me tuku tēnei kaha mā te tokotoko piston, te pane whakawhiti, me te tokotoko hono, ā, me ātete hoki e ngā peera me te anga.
Ko ngā kaha hau teitei ka arahi ki:
- Ngā piston me ngā tokotoko nui ake, taumaha ake
- Ngā kawenga amo teitei ake me te roa o te ora
- He nui ake te mōrearea o te ngenge, te whati rānei o te tokotoko
- He nui ake te wiri me te haruru
Ka tino whakaitihia ēnei kaha e te pēhanga maha-wāhanga. Mā te wehewehe i te pikinga pēhanga katoa, ka puta he wāhanga iti noa iho o te pēhanga whakamutunga i ia wāhanga. Ka puta noa te rerekētanga pēhanga nui rawa atu i te wāhanga whakamutunga, ā, ka whakamahia e taua wāhanga he piston iti ake te diameter (nā te mea kua whakaitihia te rōrahi hau). Ko te mutunga mai, he iti ake te kaha hau tihi i runga i tētahi piston kotahi i roto i te hoahoa kotahi-wāhanga e kapi ana i te ōwehenga pēhanga whānui.
Ko te tikanga o ngā kaha hau iti koia ēnei:
- Ngā anga kōpeketanga māmā ake, kiato ake
- He roa ake te ora o ngā mowhiti piston, ngā tokotoko, me ngā peera
- Te whakaiti i ngā whakaritenga wiri me te turanga
- Te pono o te miihini i roto i ngā tekau tau o te ratonga
He Tauira hei Whakaahua
Whakaarohia te pēhi i te hauwai mai i te 10 pae ki te 300 pae (he ōwehenga pēhanga o te 30:1). He tino teitei te pāmahana tukunga o te pēhi kotahi-wāhanga, ā, he tino teitei te kaha hau i runga i te piston i te mutunga o te whiu.
Tērā pea ka pēhia e te pūwero rua-wāhanga mai i te 10 pae ki te 55 pae (ōwehenga 5.5:1) i te wāhanga tuatahi, ka whakamatao i te hau, kātahi ka pēhia mai i te 55 pae ki te 300 pae (ōwehenga 5.45:1) i te wāhanga tuarua. Ka noho haumaru te pāmahana tukunga o ia wāhanga. Ko te kaha hau i runga i te piston wāhanga tuatahi ka herea e te 55 pae taurite; he iti te diameter o te piston wāhanga tuarua, nō reira ka taea hoki te whakahaere i tōna kaha hau. He iti ake te mahi katoa, ā, he pai te oma o te pūwero mō ngā tau.
Āhea te wā e hiahiatia ai te pēhitanga maha-wāhanga?
Hei tikanga whānui, ina neke atu te ōwehenga pēhanga whānui i te 6:1 mō te hau, i te 4:1 rānei mō te hauwai (nā te nui ake o te ōwehenga wera motuhake), he mea pai te whakamahi i te pēhanga maha-wāhanga. Mō ngā ōwehenga neke atu i te 10:1, e hiahiatia ana i ngā wā katoa. Ko te nuinga o ngā pēhanga tauutuutu ahumahi pēhanga teitei (hei tauira, 200–400 pae mō te CNG, 350–700 pae mō te whakakī hinu hauwai) e whakamahi ana i ngā wāhanga e toru, e whā rānei.
