Pūwhakamatao Hau Whakauru: Te Tūranga o te Kaitiaki Hiko me ngā Tohu Hapa
I roto i te whānau o ngā mīhini turbocharged, ko te hau whakamatao whakauru te "kaitiaki mana". He āhua iti noa iho te āhua engari he mea nui tana mahi ki te whakarei ake i te mana me te tiaki i te mīhini. I taua wā anō, ka pā kino pea tōna pakaru ki te mahi a te waka, me aroturuki tonu ngā taraiwa i a ia.
1. Pūwhakamātao Hau Whakauru: Te Āwhina Matua o ngā Mīhini Turbocharged
Ka whakanuia e ngā miihini turbocharged te nui o te hau e tomo ana mā te pēhi i te hau, ā, ka whakanuia te mana. Heoi, i te wā e pēhi ana, ka tino piki te pāmahana o te hau, tae atu ki te 150°C, neke atu rānei. Ka whakaitihia e te pikinga o te pāmahana te mātotoru o te hau me te nui o te hāora, ka pā ki te pai o te utu o te miihini. I tēnei wā, ka whai wāhi te whakamatao hau e tomo ana.
Ko te mahi matua o te pūwhakamatao hau whakauru ko te whakaheke i te pāmahana o te hau kōpeke. Mā roto i ngā pūnaha whakamatao hau, whakamatao wai rānei, ka taea e ia te whakamatao i te hau whakauru wera ki te 50-80°C. Ka taea e te hau makariri matotoru ake te whakanui ake i te rahinga whakauru mā te 30% pea, ka taea ai te tahunga wahie tino pai ake me te whakaputa mana kaha ake. E whakaatu ana ngā raraunga i raro i ngā āhuatanga ōwehenga hau-wahie ōrite, ko ia hekenga 10°C o te pāmahana hau turbocharged ka taea te whakanui ake i te mana miihini mā te 3% ki te 5%.
Haunga te whakarei ake i te mana, ko te hau whakamatao whakauru te "kaitiaki" o te miihini. Ko te hau wera kāore i whakamataohia e tomo ana ki te rūma mura ka tino teitei te pāmahana mura, ka nui ake te mōrearea o te pahūtanga, ā, i ngā wā tino kino, ka pakaru ngā piston, ngā takirere, me ētahi atu wāhanga. Ka taea e te hau whakamatao whakauru te whakaiti i te tūponotanga o te pahūtanga neke atu i te 60%, ā, ka taea hoki e te pāmahana hau whakauru pumau te whakaiti i te ihirangi NOx i roto i te hau hau o te miihini, ka whakaheke i ngā tukunga kino mā te 20%-30%, ka āwhina i ngā waka ki te whakatutuki i ngā paerewa tukunga tino pakari.
Mō te penapena wahie, ka whai wāhi anō te hau whakamatao whakauru. Ka taea e te hau whakamatao kiato teitei ake te whakapai ake i te 15% o te pai o te whakakorikori wahie, me te whakahaere tika i te ōwehenga hau-wahie, ka eke ki te pikinga 5%-8% o te penapena wahie. Ko ngā miihini turbocharged me ngā hau whakamatao whakauru ka pau te wahie 10%-15% iti iho i ngā miihini mura-ake o te mana kotahi. I ngā wāhi teitei, ka taea e te hau whakamatao whakauru te whakanui ake i te kiato whakaurunga mā te 25%, me te turbo ōwehenga kōpeketanga teitei, ka whakaiti i te ngaronga mana mai i te 35% ki te 15%, ka taea e ngā waka te pupuri i te mana kaha ahakoa i runga i ngā rori teitei.
2. Ngā Pānga Hapa: Ngā Tohu Noa o te Rahunga o te Pūwhakamātao Hau Whakauru
Kia pakaru te pūwero hau whakauru, ka tukuna tonutia e te waka he "tohu haumaru". Me tūpato ngā taraiwa ki ēnei āhuatanga rerekē.
Ko te hekenga o te mana te whakaaturanga tino kitea. Ina pakaru te hau whakamatao whakauru, kāore e taea te whakamatao pai i te hau wera, ka heke te mātotoru whakauru. I te wā e tere ana te whakatere, ka puhoi te urupare a te turbo, ka piki te tere o te miihini engari kāore e tino piki te tere o te waka. Ina eke ki runga, ina piki rānei, ka kitea te korenga o te mana. Ka tino uaua ngā mahi i mua he māmā noa iho, ā, ka tino heke te maeneene o te taraiwa.
He tohu noa anō hoki te pikinga nui o te whakapaunga wahie. Ka heke te pai o te whakauru o te hau ina kore e pai te hau, ā, kāore e taea te tahuna katoatia te wahie. I raro i te maero kotahi, ka piki ake te auau o te whakakī hinu, ā, ka piki tere te utu mō te whakamahi i te waka. I taua wā anō, ka puta he paoa pango i roto i te putanga hau, e kore e whakapoke noa i te taiao engari he tohu mārama hoki mō te mahi hē o te miihini.
Ka taea hoki e te hau whakamatao whakauru te pakaru te kino o te roto o te miihini. Mēnā ka tino turuturu te hau whakamatao whakauru, ka uru pea ngā matūriki onepu ki roto i te rango, ka nui ake te pakaru o te rango, ka puta he mahi kore pumau o te miihini, he wiri rerekē, me te haruru. Mā te tahunga koretake mō te wā roa ka nui te putunga waro ki runga i ngā takirere me ngā pane rango, ka raru ai te mura o te miihini, te noho kore pumau, me te peke noho kore pumau i te wā e tatari ana ki ngā rama huarahi. I te ata, ka roa ake te wā e tīmata ai te waka, ā, ka kore e pumau te noho kore pumau i te wā e tatari ana ki ngā rama huarahi.
Hei tāpiritanga, mā te kitenga OBD, ka taea te kite i te pikinga rerekē o te pāmahana hau whakauru. Ka taea e te whakamatao hau whakauru e mahi ana te whakamatao i te hau kōpeke mai i te 200°C ki te 50-80°C. Mēnā he hapa, ka neke ake pea te pāmahana hau whakauru i te 100°C, ā, ka puta te pahūtanga i te pāmahana teitei tonu. I roto i te wā, ka kino te piston me te rango. Mēnā ka turuturu te whakamatao i roto i te intercooler whakamatao-wai, mēnā rānei he paru hinu kei runga i te mata o te intercooler whakamatao-hau, ka pā ki te pānga marara wera, ā, ka arahi ki te raupapa o ngā hapa.
III. Te Tiaki i ia Rā: Kia "Whakahaere" te Intercooler
Hei whakarite kia mahi tonu te hauhautanga o te intercooler, he mea nui te tiaki i ia rā. E taunakihia ana kia horoia te totohu wera o te intercooler i ia 20,000 kiromita, inā koa i muri i te taraiwa tawhiti, kia kore ai e aukati te puehu, e pā kino ki te pai o te tohatoha wera. I taua wā anō, tirohia tonutia te paipa whakauru. Mena ka kitea he paru hinu, tera pea nā te tawhito o ngā hiri, ā, me whakakapi i te wā tika. Ina whakamahi ana i te ārai huka i te takurua raki, whiriwhiria te whakatakotoranga me te ira huka o te -35°C kia kore ai e huka te intercooler i roto.
Hei tirotiro mēnā kei te turuturu te hau waenga, ka taea e koe te tāpiri i te wai whakamātao konutai 2% i te 70 ki te 80°C kia kī tonu. Taria mō te 15 meneti, tirohia mēnā he turuturu. Mēnā he turuturu, me whakatika i te wā tika.
Ahakoa ehara te intercooler i te wāhanga tino kitea o te waka, he mea nui tana mahi ki te whakaputa hiko, ki te tiaki i te miihini, me te penapena wahie. Mā te mārama ki tana mahi, te mōhio ki ana tohu hapa, me te mahi tiaki auau ka taea te pupuri i te miihini turbocharged kia pai te āhua, ā, ka pai te wheako taraiwa a te taraiwa.
