He aha te mahi a te pūoko pēhanga whakauru i roto i te motuka?
Ko te mahi matua o te pūoko pēhanga whakauru waka (pūoko MAP) ko te aroturuki i te pēhanga tino i roto i te manifold whakauru miihini me te huri i te tohu pēhanga hei tohu hiko hei tuku ki te ECU miihini (Electronic Control Unit), koinei te pūtake matua mō te ECU ki te tatau i te rōrahi werohanga wahie me te koki whakamua mura.
Ka taea te wehewehe i tōna arorau mahi motuhake me tōna toronga mahi ki ngā wāhanga e rua e whai ake nei:
Ka rerekē te pēhanga o te manifold whakauru o te mīhini i ngā tere me ngā kawenga rerekē ina taurite te tuku wahie ki ngā āhuatanga mahi rerekē. Hei tauira, ina nui te whakatuwheratanga o te throttle (i raro i te kawenga taumaha), he teitei te pēhanga o te manifold whakauru, ā, ka whakanuia e te ECU te rahinga werohanga wahie i runga i te tohu pūoko. Ina iti te whakatuwheratanga o te throttle (i raro i te kawenga iti), he iti te pēhanga, ā, ka whakaitihia e te ECU te rahinga werohanga wahie kia mau tonu ai te ōwehenga hau-wahie o te mīhini i roto i te awhe tino pai i raro i ngā āhuatanga whakahaere rerekē, me te whakapai ake i te pai o te mura.
I roto i tētahi mīhini e mau ana i te turbocharging, ka taea hoki e te pūoko pēhanga whakauru te āwhina ki te aroturuki mēnā he noa te pēhanga whakanui, kia kore ai e pakaru te mīhini i te whakanui nui. Ka whakakotahihia hoki e ētahi tauira āna tohu hei whakapai ake i te whakahaere noho mangere me te pai o te horoinga o te hau.
Ko ngā hapa noa o ngā pūoko pēhanga whakauru waka (ngā pūoko MAP) me ngā tohu e pā ana ki te waka ka taka ki ngā wāhanga e whai ake nei:
Hapa ara iahiko pūoko
Kei roto i tēnei ko ngā āhuatanga pēnei i ngā ara iahiko poto, ngā ara iahiko tuwhera, ngā mono kua waikura, me te whakapā ngoikore.
Ngā tohu e rite ana: Te tere o te miihini kāore i te pumau, te ngoikore o te whakaterenga, ā, i ngā wā kino, ka puta pea te whakaroa. Ka tuhia pea e te ECU te waehere hapa, ka whakamārama i te tohu hapa o te miihini.
Kua pakaru ngā wāhanga o roto o te pūoko
Ko te raru matua kei roto i te rahunga o ngā wāhanga pēnei i te maramara pūoko pēhanga me te ara iahiko whakanui tohu o te pūoko, e kore ai e taea te tuku urupare tika ki te tohu pēhanga o te manifold whakauru.
Ngā tohu e rite ana: Te tatau hē o te rahinga wahie werohanga, ka hua ake he ranunga momona rawa, he ranunga hiroki rānei. Ina momona rawa te ranunga, ka puta te paoa pango mai i te paipa putanga hau, ā, ka piki ake te whakapaunga wahie. Ina hiroki rawa te ranunga, ka heke te mana o te miihini, ā, ka hoki whakamuri te ahi.
Kua āraia, kua turuturu rānei te putanga hau o te pūoko
Ka honoa te pūoko ki te pūwero whakauru mā te ngongo korehau. Mēnā ka āraia, ka piko, ka turuturu rānei te ngongo korehau, ka hē te tohu pēhanga e kohia ana e te pūoko.
Ngā tohu e rite ana: te wiri o te noho mangere, te whakaroa o te whakaterenga. Tērā pea ka tere rawa te noho mangere, ka iti rawa rānei te tere o ētahi tauira.
Te nekenekehanga o te tohu pūoko
He hapa huna tēnei. Kāore anō kia tino rahua te pūoko, engari kua rerekē te uara tohu putanga mai i te awhe noa.
Ngā tohu e pā ana: Kāore te waka e whakaatu ana i ngā tohu mārama o te hapa, engari tera pea ka puta ngā raruraru pēnei i te pikinga o te whakapaunga wahie me te hekenga o te urupare hiko. Ka taea anake te kite i ēnei raruraru mā te whakamahi i tētahi taputapu tātaritanga hei pānui i te rerenga raraunga.
Hei whakatau mēnā he noa te tohu o te pūoko pēhanga whakauru waka (pūoko MAP), e rua ngā huarahi matua: te pānui i te rerenga raraunga me te taputapu tātaritanga me te ine i te ngaohiko/ātete me te mita maha. Ko te mahi motuhake koia tēnei:
I. Te pānui i te awa raraunga me te taputapu tātaritanga (te mea e whakamahia whānuitia ana, e tika ana hoki)
Honoa te taputapu tātaritanga waka ki te atanga OBD o te waka, tomo ki te pūnaha whakahaere miihini, tīpakohia te mahi "Pānuihia te Rerenga Raraunga", ka kimi i te tūemi "Pēhanga Mutunga o te Intake Manifold".
Whakatauritehia ngā uara pēhanga i raro i ngā āhuatanga mahi rerekē kia kite ai mēnā kei roto i te awhe paerewa (tērā pea ka rerekē ngā paerewa i waenga i ngā tauira waka rerekē, tirohia te pukapuka tiaki)
Āhua noho mangere: Ko te uara pēhanga noa kei waenga i te 20 me te 40kPa.
I raro i te āhua o te whakatuwheratanga katoa o te pūkaha (te whakaterenga ohorere), ka tere te piki o te uara pēhanga ki te 80 ki te 100kPa (e tata ana ki te pēhanga o waho).
Momotuhia te ngongo korehau o te pūoko: Ka piki tonu te pēhanga, ka tata ki te pēhanga o waho, e tohu ana kei te rere pai te pūoko me te paipa.
Mena ka noho pūmau tonu ngā uara o te rerenga raraunga, ka tino rerekē rawa atu rānei i te awhe paerewa, ka kore rānei e whakaatu i te urupare ki ngā huringa o ngā āhuatanga mahi, he tohu tēnei he rerekē te tohu o te pūoko.
2. Inehia te ngaohiko ki te mita maha (he pai mō te rapurongoā ā-ringa)
Kimihia te mono o te pūoko MAP. Ko te tikanga, e toru ngā waea o te pūoko: te raina hiko (5V), te waea whenua, me te waea tohu.
Tahurihia te pana whakakā ki te tūranga "ON" (kaua e tīmata te mīhini), ka ine mā te awhe ngaohiko DC o te mita maha:
Me tata ki te 5V te ngaohiko i waenganui i te raina hiko me te waea whenua (mēnā he 0, he iti rawa rānei te ngaohiko, he tohu tēnei kei te he te pūnaha hiko i roto i te raina, i te ECU rānei).
Ko te ngaohiko i waenga i te raina tohu me te raina whenua he 0.5 ki te 1.5 volts i te tere mangere. Ina tuwhera katoa te pūwero, ka piki te ngaohiko ki te 3.5 ki te 4.5 volts.
I muri i te tīmatanga o te mīhini, pēhia mārire te pētera whakatere, ka tirotiro mēnā ka piki haere tonu te ngaohiko raina tohu i te pikinga o te whakatuwheratanga o te pūwero. Mēnā ka noho tonu te ngaohiko, ka peke, ka nui ake rānei i te awhe, he tohu tēnei he rerekē te tohu a te pūoko.
Iii. Ngā Tikanga Whakawa Āwhina
Mātakihia te āhuatanga hapa: Mena kei te tere koretake te waka, he ngoikore te whakaterenga, he nui te whakapaunga wahie, ā, kei te kā te rama hapa, ā, ko te waehere hapa e pānuihia ana ko "P0106/P0107/P0108" (waehere hapa e pā ana ki te pūoko pēhanga whakauru), he tino tūponotanga kei te rerekē te tohu o te pūoko.
Tirohia te ngongo korehau: Momotuhia te ngongo korehau e hono ana ki te pūoko kia kite ai mēnā he aukati, he ngatata, he motu rānei. Mēnā ka turuturu te ngongo korehau, ka hē te tohu pēhanga i kohia e te pūoko, ā, ka whakaarohia he tohu rerekē.
