Pūoko Pēhanga Whakauru: Te "Mata Raraunga" Matua o te Mīhini
Ko te pūoko pēhanga whakauru (whakarāpopototia ko te pūoko MAP) he wāhanga matua o te pūnaha werohanga wahie momo-D i roto i ngā miihini werohanga wahie hiko, hei "kaitirotiro pēhanga" o te miihini. Ka aroturuki tonu i ngā huringa pēhanga i roto i te pūnaha whakauru, ā, ka whakarato i te pūtake whakatau nui mō te waeine whakahaere miihini (ECU).
Ka honoa ki te pūwero whakauru mā te ngongo korehau, ā, ka taea te hopu tika i ngā rerekētanga o te pēhanga i roto i te pūwero whakauru i raro i ngā āhuatanga whakahaere rerekē, ka huri hei tohu hiko, ka tukuna ki te ECU. I te wā e whakateretere ana te waka, ka piki ake te pēhanga whakauru, ā, ka tukuna wawetia e te pūoko he tohu, ka whakanuia e te ECU te nui o te werohanga wahie kia rawaka ai te mana mō te miihini; i te wā e whakaheke tere ana, ka heke te pēhanga whakauru, ā, ka whakaitihia e te ECU te werohanga wahie, ka karohia te moumou wahie me te whakapai ake i te penapena wahie.
Ka taea hoki e ia te āwhina i te ECU ki te whakarerekē i te wā mura, kia mura rawa ai te ranunga, kia kitea ai te taurite pai i waenga i te putanga hiko me te whakahaere tukunga. Mō ngā miihini me ngā pūnaha whakahaere takirere hiko, ka taea hoki e te pūoko pēhanga whakauru te mahi hei tawhā tārua mō ngā tohu kawenga, hei āwhina i te whakarerekē i te wā whakatuwheratanga o te takirere whakauru me te whakapai ake i te mahi a te miihini.
Whakatūpato Rahunga: Te "Whakatūpato Hauora" o te Mīhini
Ki te kore e mahi te pūoko pēhanga whakauru, ka raruraru te taurite mahi a te mīhini, ka puta he raupapa o ngā tohu rerekē, ka tū hei mōrearea ki te mahi a te waka me te haumaru taraiwa.
Ka kore pea te ECU e taea te whakatau tika i te nui o te wahie e whakaurua ana e te pūoko tīmatanga me te kore e whakamahi i te pūoko, ā, ka puta he rerekētanga i waenga i te nui o te wahie e werohia ana me te nui o te wahie e whakaurua ana. I te tīmatanga makariri, me whakamātau tonu te miihini kia mura pai, ā, ka pai ake pea ngā tohu i muri i te whakamahana, engari ka mutu tonu te miihini i muri i te tīmatanga. I te wā e whakamahi ana i te pūoko, ka rerekē te tere o te miihini i waenga i te 800-1000 rpm, ahakoa te wiri me te tū, he rite ki te hapa o te rango, engari mā te tirotiro i ngā mono mura me ngā koiri mura ka kitea he hua noa, he mea pea nā te nekeneke o te tohu^.
Te Taurite o te Mana me te Whakamahinga Wahie I te wā e whakateretere ana, ka piki ake te tere o te miihini engari ka puhoi te piki o te tere o te waka, ka puta he "ahua o te kore taputapu", me te tino whakaroa i te urupare mana. Ko te mahi mana o ētahi tauira 1.6L ka kino ake pea i te tauira 1.0L. Nā te mea kāore e taea e te pūoko te urupare wawe i ngā huringa o te pēhanga whakauru i muri i te whakatuwheratanga o te throttle, ā, ka whakaroahia te werohanga wahie o te ECU, ka puta he āputa mana. I taua wā anō, ka taea e te hapa te meinga te ECU kia he te whakatau i te rahinga whakauru, ka puta he taurite o te kukū o te ranunga, he nui rawa te nui ka puta he paoa pango mai i te paipa putanga me te tahunga kāore i oti, he kikokore rawa rānei ka puta he koretake te mana. I roto i ngā āhuatanga e rua, ka tino piki ake te whakapaunga wahie, ā, ka taea e te whakapaunga wahie o ētahi waka te piki ake mai i te 8L/100km ki te 12L/100km^.
Te Whakamārama i te Rama Hapa me ngā Mōrearea Pea Ina neke atu te rerekētanga o te tohu pūoko i te paepae, ka mura te rama hapa miihini (MIL) i runga i te papaaho. Mā te whakamahi i tētahi taputapu tātaritanga OBD, ka taea te pānui i ngā waehere pēnei i te P0105 (raru ara iahiko pūoko) me te P0106 (tohu koretake). Tata ki te 60% o ngā hapa i puta mai i te kino o te pūoko, ā, 40% i puta mai i ngā take waea. Mā te kore aro ki ēnei tohu ka arahi pea ki ngā hapa iti ka huri hei raruraru nui, ā, i ngā wā kino rawa atu, ka tū ohorere pea te waka i te wā e taraiwa ana, inā koa i te wā e whakaheke tere ana, e neke ana rānei i te taputapu, ka puta he mōrearea nui ki te haumaru^.
Te Aroturuki Hapa: "Patua" i puta mai i ngā āhuatanga maha
Ehara i te mea kotahi te take e puta ai ngā rahunga o te pūoko pēhanga whakauru, engari he hua nō ngā take maha pērā i te pūoko tonu, te waea, me ngā ngongo korehau.
Mā te whati o te ara iahiko ā-roto, te ara iahiko poto rānei i roto i te pūoko ka kore e taea te huri me te tuku i te tohu pēhanga i te tikanga noa, pērā i te motu o te hongere i roto i te teihana whakawhiti mōhiohio, ā, e kore te ECU e whiwhi raraunga tika^.
He hapa noa anō hoki ngā tohu putanga rerekē. I te nuinga o te wā, me huri te tohu me te korehau o te manifold whakauru, ā, ki te "whakaroa" te tohu, ka whakatikatika te ECU i te werohanga wahie i runga i ngā mōhiohio hē, ka kore ai e mahi tika te miihini^. Hei tāpiri, ki te āraihia, ka turuturu rānei te ngongo korehau e hono ana i te pūoko pēhanga whakauru ki te paipa whakauru, ka ārai i te pūoko ki te kite i te tohu pēhanga tika, pērā i te pakaru o te "piriti" me te whakakorenga o te tuku mōhiohio.
Tātaritanga Tika: Whakahokia te Tirohanga o te Pūoko
I te wā e raru ana te pūoko pēhanga whakauru, ka taea te mahi i ēnei mahi hei whakatau tika i te raru: Tuatahi, whakamahia te taputapu tātaritanga hei pānui i te waehere hapa, ā, i te tuatahi ka whakatauhia te ahunga o te hapa. Mena ka whakaatuhia he waehere hapa e pā ana ki te pūoko, tirohia mēnā kua purua, kua turuturu rānei te ngongo korehau, ā, mēnā kua pakaru te waea, kua ngoikore rānei te hononga. Tuarua, whakahaerehia he whakamātautau mahi ki te pūoko, momotuhia te mono pūoko, tahurihia te pana mura, ka ine i te ngaohiko i waenga i te pito VCC me te pito E2 i runga i te mono. I te nuinga o te wā, me noho i waenga i te 4.5 me te 5.5V. Mena he rerekē te ngaohiko, tirohia te waea mai i te ECU ki te pūoko, ki te ECU rānei. Hei whakamutunga, whakamahia te tikanga whakakapinga. Whakakapia te pūoko kua whakapaetia he hapa ki tētahi pūoko noa. Mena ka ngaro te hapa, ka taea te whakaū kua pakaru te pūoko.
Ahakoa he iti te pūoko pēhanga whakauru, he mea nui mō te mahi pumau o te miihini. Mā te mārama ki tana mahi, ngā tohu hapa, me ngā tikanga tātaritanga ka āwhina i ngā kaipupuri waka ki te tautuhi i ngā raruraru i te wā tika, te karo i ngā hapa iti e hua ai ngā mate nui, me te pupuri i te miihini kia pai tonu te āhua i ngā wā katoa.
