Te mahi a te pā hiko motuka
He wāhanga matua te pā hau hiko o te waka o roto i te pūnaha whakamatao o te waka, ko tana mahi matua he pupuri i te pāmahana mahi e tika ana mō te mīhini me ngā wāhanga e pā ana, kia pai ai te whakahaere me te haumaru o te waka.
Ko te mahi matua o te pā hiko he tuku wera. Mā te akiaki i te hau kia rere ki runga i te radiator (tāke wai) hei whakamatao i te wai whakamatao o te mīhini wera, hei ārai i te wera nui o te mīhini. Ko te tikanga ka whakahaerehia e te pūoko pāmahana wai, e te pana whakahaere pāmahana rānei. Ina tae te pāmahana wai whakamatao ki tētahi paepae kua whakaritea (pēnei i te 90°C, 95°C rānei), ka tīmata aunoa, ka mutu ina heke te pāmahana, ka tutuki ai te penapena pūngao me te whakahaere pai.
Hei tāpiritanga, ka tautoko te pā hau hiko i te mahi a te pūnaha hauhautanga. I roto i ngā momo whakamatao, whakamahana rānei, ka panaia te hau kia haere mā roto i te pūwhakamātao hauhautanga, i te pūwhakarewa rānei hei whakarei ake i te pai o te whakamatao, hei tohatoha rānei i te hau wera, kia whakahaeretia ai te pāmahana o roto.
He maha ngā painga o te mana whakahaere atamai o te pā hiko, tae atu ki te arotau i te whakapaunga pūngao mā te whakarerekē i te tere (pēnei i ngā aratau tere teitei me te tere iti), te whakaiti i te kawenga mīhini, me te utu mō te korenga o te hauhautanga taiao i ngā tere iti, i te noho mangere rānei, kia pai ai te whakamatao.
Ko te rapurongoā mō te kore e hurihuri o te pā hiko me whai i tētahi huarahi taahiraa-i-te-taahiraa: Tuatahi, tirohia mēnā kei roto te pāmahana wai i te awhe paerewa (ko te pāmahana tīmatanga noa he 90-95°C). Kātahi, whakamātauria ngā fuse, ngā whakawhiti, te pana whakahaere pāmahana, me te motuka i roto i te raupapa. Anei tētahi tukanga rapurongoā pūnaha:
Arotakenga taketake (mahi matua)
Te kimi i te pāmahana wai: Whakaohohia te mīhini kia eke ki te pāmahana mahi noa (mō te 10 meneti pea), tirohia te ine pāmahana wai kei runga i te papatohu. Mena kei raro iho i te 90°C te pāmahana wai, he mea noa te kore hurihuri o te hau; mena kei roto te pāmahana wai i te awhe paerewa engari kāore tonu e hurihuri, me tirotirohia anō.
Tirotiro fiusi: Whakatuwheratia te pouaka fiusi o te wāhanga miihini, kimihia te fiusi pā (tirohia te pukapuka ā-ringa waka mō te wāhi), whakamahia he mita maha hei whakamātautau mēnā kua pahū. Mēnā kua pahū, whakakapia ki te fiusi ōrite (kaua e whakamahi i te waea parahi hei whakakapi).
Te tirotiro i ngā wāhanga matua
Whakamātautau whakawhiti:
Tīmatahia te waka, ka tahuri i te pana hauhautanga. Whakarongo ki te tangi "pāwhiri" mai i te whakawhiti.
Ki te kore he haruru, whakamahia he mita maha hei kimi i te ātete o te koiri whakawhiti (uara noa 50-100Ω). Ki te rerekē, whakakapia.
Manatoko pana whakahaere pāmahana:
Momotuhia te mono o te pana whakahaere pāmahana ka whakapoto i ngā pine. Mēnā ka huri te hau, kua pakaru te pana, ā, me whakakapi.
Ki te kore e hurihuri, tirohia mēnā kei te tuwhera te ara iahiko pana (whakamātauria ki te mita maha mō te haere tonu).
Te whakahaere hapa hohonu
Tātaritanga motuka:
Momotuhia te pūtake hiko, ka nekehia ā-ringa ngā mata o te hau. Mena he mea piri, he haruru rerekē rānei, whakahinuhinuhia te rakau hurihuri (maturuturuhia he hinu whakahinuhinu motuhake) whakakapia rānei te motuka.
Whakamātautau hiko o te motuka: Honoa he pūtake hiko 12V, ki te kore e hurihuri, he hapa motuka.
Ara iahiko me ngā pūoko:
Tirohia ngā waehere hapa o te ECU (rorohiko waka) mā te whakamahi i tētahi kaipānui OBD-II.
Whakamātauria te ātete o te pūoko pāmahana wai (i te pāmahana noa, tata ki te 200-500Ω), ki te rerekē te uara, whakakapia.
Ina pakaru te pā hiko o te waka, ka puta pea ngā āhuatanga pēnei i te wera nui o te mīhini, te turuturu o te tāke wai, me te mahi rerekē o te pā. Ko ngā āhuatanga motuhake ko te pikinga o te pāmahana o te mīhini, te korenga o te pūnaha whakamatao, me te kino o te pā. Anei te whakaahuatanga taipitopito o te whakarōpūtanga o te āhuatanga:
He hapa o te pūnaha whakamatao miihini
Ka pā tika te rahunga o te pā hiko ki te pai o te whakamatao, ka hua ake he tauhohenga mekameka:
Ka piki tere te pāmahana o te mīhini: Kia mutu te hurihuri o te hau, kāore e taea te mimiti i te wera i roto i te tāke wai, ka tere te piki o te tohu ine pāmahana (neke atu i te 95°C), ka kā te rama whakatūpato pāmahana wai i te papaaho whakahaere, ka ngaro pea te hiko, ka mutu rānei te mīhini.
Ka pakaru, ka turuturu rānei te tāke wai: Ka piki tere te pēhanga i roto i te tāke wai i te pāmahana teitei, ka pakaru te tāke wai, ka pakaru rānei te hiri, ā, ka poke te whenua i te wai whakamatao. Ka āraia te rere o te wai, ka nui ake te wera o te mīhini.
He kino nui ki te mīhini: Ka pā te pāmahana tiketike tonu ki te "rango paheke" (ka turuturu te wai whakamatao ki roto i te rango), ka mutu ka piri te piston, ka kore e pai te hinu whakahinuhinu, ā, i te mutunga ka hiahiatia he whakatikatika nui, he whakakapinga rānei mō te mīhini.
Ngā tohu o te rahunga o te pā hiko
Ka taea te kite i ēnei mā te tirotiro tika, mā te mahi rānei:
Ngā tohu tahunga me ngā haunga: Ka mangu te koiri putanga hau o te motuka, ka puta he haunga tahunga kirihou, he haunga poto rānei o te waea.
Hurihanga puhoi, mutu rānei: He uaua ki te huri ā-ringa i te rakau, ā, kāore i te maeneene te nekehanga (kāore he hinu i te peera, kāore rānei te rotor i te tika te tūnga).
Kāore he haruru o te mahi a te pā hau i roto i te wāhanga miihini, kāore hoki he hau e rangona ana i te pā atu.
Pāmahana rerekē: Ka tere rawa te piki o te pāmahana o te mata o te pā (ka wera mō te wā poto), he tohu tēnei kei te puta he ara iahiko poto o roto.
Ētahi atu pānga e pā ana
Te rahunga o te whakamatao o te hauhautanga: Ko te korenga o te wera e marara ka hua ake te pēhanga nui rawa i roto i te paipa pēhanga teitei o te hauhautanga, ka hua ake te hua o te whakamatao ngoikore, te pakaru rānei o te paipa.
Haruru rerekē: Ka mau te motuka, ka puta he oro waku, he oro rerekē rānei he auau teitei.
Whakatūpato: Ina eke te pāmahana o te wai ki runga ake i te 80℃, me tīmata aunoa te hau. Ki te kore e hurihuri, me whakatika tonu kia kore ai e pakaru te miihini.
