Te mahi a te pūoko hāora o muri o te motuka
I roto i te pūnaha whakahaere tukunga o ngā motuka, ahakoa he iti te rahi o te pūoko hāora o muri, he mahi nui tāna hei "aroturuki hau hiku". Ka pā tika tana mahi ki ngā āhuatanga mahi o te miihini me te kounga o ngā tukunga hau. He mea tino nui te mārama ki tana mahi, ngā āhuatanga o te hapa, me ngā take mō ngā kaipupuri waka i roto i ā rātou taraiwa o ia rā me te tiaki waka.
Ko te kawenga matua o te pūoko hāora o muri ko te aroturuki i te whai huatanga o te purenga o te kaitahuri whakaterenga-toru-ara. Kei muri i te kaitahuri whakaterenga-toru-ara te tāutanga, ā, ka kitea te nui o te hāora i roto i te hau putanga kua purea, ka tukuna ngā raraunga ki te waeine whakahaere hiko o te miihini (ECU). Ka whakataurite te ECU i ngā raraunga mai i te pūoko hāora o mua (kua tāutahia ki te pūoko putanga, e aroturuki ana i te nui o te hāora i roto i te hau putanga taketake) hei whakatau mena kei te mahi tika te kaitahuri whakaterenga-toru-ara. I raro i ngā āhuatanga noa, i muri i te purenga e te kaitahuri whakaterenga-toru-ara, ka noho pumau tonu te nui o te hāora i roto i te hau putanga, ā, he iti ake te rerekētanga o te tohu o te pūoko hāora o muri i tērā o te pūoko hāora o mua; ki te heke te rerekētanga o ngā tohu i waenga i ngā mea e rua, ki te rite tonu rānei, e tohu ana kua rahua pea te kaitahuri whakaterenga-toru-ara, ā, kāore e taea te huri pai i ngā hau kino. Hei tāpiri, ka āwhina hoki ngā raraunga urupare mai i te pūoko hāora o muri i te ECU ki te whakatikatika i te nui o te weronga wahie, me te whakarite ā-kore i te whai huatanga o te mura o te miihini.
Ki te kore e pai te pūoko hāora o muri, ka puta he maha ngā tohu rerekē i roto i te waka, ka pā kino ki te wheako taraiwa me te mahi a te waka. Ko te tohu tino kitea ko te whakahohenga o te rama hapa miihini. Ina he rerekē te tohu pūoko, ka whakaoho te rorohiko o runga i te rama whakatūpato hapa. Mā te whakamahi i tētahi taputapu tātaritanga OBDII, ka taea te pānui i ngā waehere hapa e tika ana pērā i te P0136 ki te P0141. He āhuatanga noa anō hoki te hekenga o te mahi mana. Nā te kore e taea e te pūoko te whakaata tika i ngā raraunga ihirangi hāora, ka hē te whakahaere a te ECU i te nui o te werohanga wahie, ka hua ake he nui rawa te tahunga, he iti rawa te pai o te tahunga, he puhoi te whakatere, he koretake te kaha piki, me te pikinga pea o te tere, te wiri o te tinana, te mutu rānei o te miihini i te wā e noho puku ana. I taua wā anō, ka nui ake te pikinga o te kai wahie. E whakaatu ana ngā raraunga ka piki ake te nui o te werohanga wahie i te korenga o te pūoko hāora o muri mā te 5% ki te 10%. Mō tētahi motuka whānau he 20,000 kiromita te maero ia tau, ka taea e te kai wahie tāpiri ia tau te eke ki te 900 rita, ka hua ake he mate ōhanga nui. Ka rerekē anō hoki ngā tukunga hau. Tērā pea ka mangu te āhua o te hau putanga kore-parakore, ā, he haunga kino hoki, e kore e whakapoke i te taiao anake, engari ka kore hoki te waka e eke ki te whakamātautau putanga i te tirotiro ā-tau. Tērā pea ka kitea ētahi tohu huna pēnei i te tīmatanga makariri puhoi, te wiri iti i te tīmatanga o te hauhautanga, tae atu ki te tū o te mīhini, e kore e arohia e ngā rangatira.
He uaua, he kanorau hoki ngā take o te rahunga o te pūoko hāora o muri. Ka taea te whakarōpū kia toru ngā wāhanga. Tuatahi, ngā take kounga wahie. Ko te wahie kounga iti kei roto ko te whanariki, te mata, me ētahi atu, ka hanga he paparanga poke i runga i te mata o te pūoko i muri i te tahunga, ka aukati i te horapa o ngā katote hāora, ka puta he whakaroa, he whakapōturi rānei i te tohu; ka hanga he tioata mā i runga i te wāhanga pūoko, ka heke ohorere te aro o te neke atu i te 60%. Tuarua, te koroheketanga o te ara iahiko me te wāhanga. Ka roa te wā e pāngia ana te whitiki waea pūoko e te pāmahana teitei me te haumākū teitei, ā, he ngāwari te koroheketanga o te paparanga whakamarumaru, ka whakanui ake te waikura o ngā hononga i te ātete whakapā, ā, ka ārai te ara iahiko whakamahana pakaru i ngā wāhanga kia eke ki te paepae mahi 300°C, ka hua ake he tohu rerekē e whiwhihia ana e te ECU. Tuatoru, ngā putunga waro me te parahanga. Ko te tahunga kore oti i roto i te miihini ka puta he putunga waro, te hinu, te puehu rānei, ka uru ki te taiao mahi pūoko, ka kapi i te mata o te wāhanga pūoko, ka whakararuraru i te kitenga o te ihirangi hāora. Ina koa kua neke atu i te 80,000 kiromita te tawhiti o te waka, ka eke te kohi o ngā putunga waro ki te 0.2-0.5mm, ka tino whakaiti i te mahi a te pūoko.
Mēnā ka raru te pūoko hāora o muri, me mahi ngā kaipupuri waka i ngā mahi i te wā tika. I a koe e taraiwa ana i ia rā, whiriwhiria he teihana wahie whai tohu hei tāpiri wahie, ā, whakamahia ngā kaihoroi pūnaha wahie i ia wā hei whakaiti i te kino o te pūoko i puta mai i ngā poke; whai i ngā taunakitanga i roto i te pukapuka tiaki waka, aroturukihia te pihi tohu pūoko i ia 30,000 kiromita, ā, mahihia te horoi ngaio i ia 50,000 kiromita hei ārai i te kohikohinga o ngā putunga waro. Mēnā ka kitea ngā tohu hapa o runga ake nei i te waka, me whakamātautau wawe tonu i tētahi whare whakatika ngaio. Mā te whakataurite i ngā ngaru me ētahi atu tikanga, whakaūhia te tūnga o te pūoko. I te wā e whakakapi ana i te pūoko, e taunakihia ana kia whiriwhiria ngā wāhanga wheketere taketake. Ko te auau whakahokinga mai o ēnei wāhanga he 8% noa iho, he iti iho i te 35% o ngā wāhanga hokohoko muri. Whai muri i te whakakapinga, me tautuhi anō ngā tawhā ECU kia hoki ai te waka ki te mahi noa.
He wāhanga nui te pūoko hāora o muri o te pūnaha tukunga hau o te waka. Ko tōna mahi pumau te taurangi mō te mahi pai o te miihini me te tutuki i ngā tukunga hau. Mā te whakanui i tōna mahi, te mārama ki ngā āhuatanga me ngā take o te hapa, me te mahi i ngā mahi tiaki auau me te whakatika i te wā tika ka taea ai e te waka te noho pai tonu, ā, mā reira ka whakaitihia ngā utu whakamahi me te whai wāhi ki te tiaki taiao.
