He aha te pūoko pēhanga whakauru waka?
Ko te pūoko pēhanga whakauru waka (pūoko MAP) he wāhanga hiko e whakamahia ana hei kite i te pēhanga tino i roto i te miihini whakauru. Mā te huri i ngā huringa pēhanga ki ngā tohu ngaohiko, ka tukuna ngā raraunga ki te ECU hei whakahaere i te rahinga werohanga wahie me te wā mura. Koinei te whakamārama motuhake:
Mahi matua
Aroturukihia te pēhanga o te pūwero whakauru: Honoa te pūwero whakauru ki te ngongo korehau hei rongo i ngā panonitanga pēhanga tuturu i muri i te pūwero.
Ngā tawhā whakahaere miihini: Ka whakarerekē te ECU i te wā werohanga wahie me te koki whakamua mura i runga i ngā tohu pūoko hei whakapai ake i te putanga hiko me te whakapaunga wahie.
Te kaupapa mahi
Te Pūoko Pēhanga: Ka kitea e ngā wāhanga tairongo ā-roto (pērā i ngā varistor, ngā diaphragm capacitive) ngā huringa pēhanga, ā, ka hurihia hei huringa ātete, hei capacitance rānei.
Te tahuritanga tohu: Ka whakanuia e te ara iahiko whakauru ngā huringa, ka hurihia hei tohu ngaohiko, ka tukuna ki te ECU.
Ngā horopaki tono
Pūnaha werohanga momo-D: Ka kitea ā-kore te nui o te hau e tomo ana. Kāore i rite ki ngā pūoko rere tika (MAF), me tatau ngātahi me te tere hurihuri me te kawenga.
Pānga hapa: Ka taea e te kino te whakakī rawa i te ranunga, te whakaiti rānei i te kaha, te whakanui rānei i te whakapaunga wahie.
Ngā whakaaro tiaki
Tirotiro auau: Kia aro ki te hononga o ngā ngongo korehau me te pumau o ngā tohu hei karo i ngā hapa i puta mai i ngā putunga waro, i te koroheketanga rānei.
Ko te pūoko pēhanga whakauru waka tētahi o ngā wāhanga nui o te pūnaha whakahaere miihini. Ko tana mahi matua he aroturuki i te pēhanga hau i roto i te pūwero whakauru me te tuku raraunga i te wā tūturu ki te waeine whakahaere miihini (ECU). Mā te ine tika i te pēhanga whakauru, ka taea e te ECU te tatau i te nui o te werohanga wahie me te wā mura e tika ana, kia pai ai te mahi a te miihini i raro i ngā āhuatanga mahi rerekē.
Te kaupapa mahi
Ko te pūoko pēhanga whakauru ka tāutahia ki runga i te manifold whakauru, ā, ka mahi mā te rongo i ngā huringa o te pēhanga hau i roto i te manifold whakauru. Ko te wāhanga matua o roto i te pūoko he waeine pūoko varistor, he waeine pūoko capacitive rānei. Ina huri te pēhanga hau, ka huri te uara ātete, te uara capacitance rānei o te waeine pūoko, ā, ka puta he tohu hiko e rite ana. I muri i te whiwhinga i tēnei tohu, ka whakakotahi te ECU i ngā raraunga mai i ētahi atu pūoko (pēnei i ngā pūoko rere hau, ngā pūoko tūnga throttle, me ētahi atu) hei tatau whānui i te rahinga wahie o nāianei me te wā mura e hiahiatia ana e te miihini.
He hononga tata te pai o te mura o te miihini ki te ōwehenga hau-wahie. Mā te pūoko pēhanga whakauru ka āwhina i te ECU ki te whakatau tika i te nui o te hau e tomo ana ki te rango, ā, mā reira ka whakarerekē i te rahinga weronga wahie kia tutuki ai te ōwehenga ranunga tino pai. Ki te kore e pai te pūoko, ka nui rawa te momona o te ranunga, ka pā ki te putanga hiko me te pikinga o te whakapaunga wahie.
Whakarerekē ki ngā āhuatanga mahi rerekē
Ka rerekē te pēhanga whakauru i raro i ngā āhuatanga mahi rerekē pēnei i te noho puku, te whakaterenga me te whakahekenga. Ka aroturukihia ēnei huringa e ngā pūoko i te wā tūturu, ka taea ai e te ECU te whakarerekē hihiri i te tuku wahie me te wā mura, kia pai ai te whakahaere o te miihini. Hei tauira, i te wā e tere ana te whakaterenga, ka piki te pēhanga whakauru, ā, ka whakanuia e te ECU te nui o te weronga wahie kia kaha ake ai te mana.
Whakapai ake i te penapena wahie
Mā te whakahaere tika i te ōwehenga hau-wahie, ka āwhina te pūoko pēhanga whakauru ki te whakaiti i te whakapaunga wahie kore e hiahiatia. Mena he rerekē te tohu a te pūoko, kāore pea e taea e te ECU te whakarite tika i te rahinga weronga wahie, ka hua ake te pikinga o te whakapaunga wahie.
Whakaitihia ngā tukunga
Ehara i te mea ka whakarei ake i te pai o te tahunga te ōwehenga hau-wahie e tika ana, engari ka whakaitihia hoki te tukunga o ngā hau kino. Mā te mahi noa o te pūoko pēhanga whakauru ka āwhina i te miihini ki te whakatutuki i ngā whakaritenga tiaki taiao me te whakaiti i ngā poke i roto i te hau putanga.
Ngā momo noa
Ko ngā momo pūoko pēhanga whakauru e wātea ana i te mākete i ēnei rā ko ēnei:
Pūoko piezoresistive: Ka whakamahia e ia te pānga piezoresistive o ngā rauemi semiconductor hei huri i ngā huringa o te pēhanga hau hei tohu hiko.
Pūoko capacitive: Ka ine i te pēhanga mā te kite i ngā huringa o ngā uara capacitance i puta mai i ngā rerekētanga o te pēhanga hau.
Pūoko kiriata angiangi: Ka whakamahia e ia te hangarau ine taumahatanga kiriata angiangi, ā, he tino tika, he pumau hoki.
Ngā āhuatanga me ngā pānga o ngā hapa
Kia kore ai e mahi tika te pūoko pēhanga whakauru, ka pāngia pea te āhua mahi o te miihini. Ko ngā āhuatanga noa o te hapa ko:
Te tere noho kore pumau: Tērā pea ka kore e taea e te ECU te whakahaere tika i te tere noho kore e pai ngā tohu pūoko rerekē, ā, ka hua ake te wiri o te mīhini, te tū rānei.
Te hekenga o te mana: Mena he hē ngā raraunga pēhanga whakauru e whiwhihia ana e te ECU, ka kore pea e ranea te werohanga wahie, ka ngoikore ai te whakaterenga.
Te pikinga ake o te whakapaunga wahie: Mā ngā tohu pēhanga hē ka hē te whakatau a te ECU i te rahinga whakauru, ka nui rawa te tuku wahie.
Ina kā te rama hapa: Ka aroturukihia e te ECU o ngā waka hou ngā tohu a te pūoko. Kia kitea he hapa, ka tiaho pea te rama hapa o te miihini.
Te tiaki me te tirotiro
Hei whakarite kia mahi tonu te pūoko pēhanga whakauru, e taunakihia ana kia whakahaerehia ngā tirotiro auau e whai ake nei:
Horoia te pūoko: I muri i te whakamahinga roa, ka kohikohi pea te puehu, te hinu rānei ki te mata o te pūoko, ka pā ki te tika o te ine. Ka taea e koe te muru mārire ki tētahi mea horoi motuhake.
Tirohia te hononga raina: Ka raru pea te tuku tohu i ngā mono pūoko, i ngā taura waea rānei kua waikura, kua kore rānei e pai te tuku. He mea tika kia pono te hononga.
Whakamahia ngā taputapu tātaritanga hei kimi: Mena he rerekē te mahi a te miihini, ka taea te pānui i te waehere hapa mā te taputapu tātaritanga OBD hei whakatau mena kei te mahi tika te pūoko.
Te mahi tahi me ētahi atu pūoko
Kāore te pūoko pēhanga whakauru e mahi takitahi. Ka mahi tahi me ētahi atu pūoko hei tautoko raraunga mō te ECU. Hei tauira:
Pūoko rere hau: Ka ine tika i te nui o te hau e tomo ana ki te miihini, ā, ka manatokohia mā te whakamahi i ngā raraunga mai i te pūoko pēhanga whakauru.
Pūoko tūnga o te pūwero: Ka aroturuki i te whakatuwheratanga o te pūwero hei āwhina i te ECU ki te tatau tika ake i te rōrahi whakauru.
Pūoko hāora: Ka whakahoki kōrero i te hanganga o te hau putanga i muri i te tahunga, kia pai ake ai te ōwehenga hau-wahie.
Ngā au whanaketanga hangarau
I te whanaketanga o te hangarau hiko o ngā motuka, kua piki haere tonu te tika me te pono o ngā pūoko pēhanga whakauru. I ngā rā kei te heke mai, ka noho te whakaurunga me te mātauranga hei huarahi whanaketanga. Hei tauira, ka taea te whakauru i te pūoko pēhanga whakauru me te pūoko pāmahana ki roto i te waeine kotahi hei whakaiti i te noho o te wāhi me te whakarei ake i te ōritetanga o ngā raraunga. Mā te whakamahinga o ngā rauemi hou ka whakarei ake i te ātete pāmahana teitei me te kaha ārai-whakararuraru o ngā pūoko.
Hei whakarāpopototanga, he mahi nui tā te pūoko pēhanga whakauru o te motuka i roto i te pūnaha whakahaere miihini. Ka pā tika tana mahi noa ki te mahi a te miihini, te ōhanga me te mahi tukunga. Mā te mārama ki tana mahi me ngā āhuatanga hapa noa ka āwhina i ngā kaipupuri motuka ki te tautuhi me te whakaoti rapanga i te wā tika, kia pai ai te whakahaere o te waka.
