He aha te tikanga o te pūoko o te porowhita crankshaft o te waka?
Ko te pūoko crankshaft, e mōhiotia ana ko te pūoko tūranga crankshaft, he pūoko matua i roto i te pūnaha whakahaere hiko miihini. Ko te nuinga o te whakamahinga hei kite i te tūranga hurihuri o te crankshaft, te tohu pokapū mate o runga o te piston, me te tere miihini, ā, ka whakarato i ngā raraunga matua ki te waeine whakahaere miihini (ECU) hei whakahaere i te wā mura me te wā werohanga wahie. Ko te kaupapa mahi o te pūoko crankshaft e whakawhirinaki ana ki tōna momo, tae atu ki te momo whakapūtanga aukume-hiko, te momo pānga Hall, me te momo whakaahua-hiko. Ka whakaputahia e te momo whakapūtanga aukume-hiko ngā tohu mā te whakapūtanga hikohiko, ka tautuhia e te momo pānga Hall te tūranga mā te whakamahi i ngā huringa ngaohiko Hall, ā, ka tukuna e te momo whakaahua-hiko ngā mōhiohio mā te aukati i te kōhao mārama me te huringa tohu whakaahua-hiko; ka mahi tahi ēnei pūoko me te pūoko tūranga camshaft hei whakatau tika i te koki crankshaft me te tere koki, hei whakarite i te tika o te wā mura me te wā werohanga wahie. He mea nui tana mahi, ehara i te mea ko te whakatau i ngā wā mura me te wā werohanga wahie anake, engari me te tātari hoki i ngā huringa koki crankshaft hei kite i te hapa o te miihini me te whakarato tautoko raraunga mō te whakahaere mangere me te whakahaere mimiti wahie. I roto i te tiaki waka, ko ngā hapa noa o te pūoko crankshaft ko te ngaronga tohu, te pokanoa rānei, ka raru pea te tīmatanga o te miihini, te noho koretake, te ngaronga hiko rānei; ko ngā tikanga kimi ko te tirotiro i ngā hononga waea, ngā tohu putanga, ngā uara ātete pūoko rānei kia pai ai te mahi.
Ko ngā hapa noa o te pūoko o te porowhita crankshaft ko te ngaronga tohu, te pokanoa rānei, ka raru pea te whakaoho i te mīhini, te noho koretake, te ngaronga hiko rānei; ko ngā tikanga kimi ko te tirotiro i ngā hononga waea, ngā tohu putanga, ngā uara ātete pūoko rānei kia pai ai te mahi.
Ka taea e te rahunga o te pūoko o te porowhita te whakaputa i ngā tohu pēnei i te rahunga o te tīmatanga o te miihini, te wā whakakā me te werohanga wahie pōrearea, te wiri nui ake o te miihini me te whakaweto whakaterenga, me ētahi atu, ā, he mea tika kia tirohia me te whakakapi i te wā tika.
Ngā tohu tīmatanga me ngā tohu whakahaere rerekē
Ko te korenga o te pūoko o te crankshaft ka pā tika ki te wā mura me te wā werohanga wahie o te miihini, ā, ka whakaatuhia penei:
Te uaua ki te tīmata, te kore rānei e taea te tīmata: Nā te kore e taea e te pūoko te whakarato i te tohu tūranga o te crankshaft, kāore e taea e te ECU (wae whakahaere miihini) te whakahaere i te mura me te werohanga wahie, ka hua ake he wā tīmatanga neke atu i te 5 hēkona, he maha rānei ngā rahunga mura, ā, i ngā wā tino kino, ka motuhia te hiko ngaohiko teitei me te werohanga wahie.
Te wiri o te miihini me te ngaronga o te mana:
Te noho pūmau kore: Ka rerekē te tere o te miihini i waenga i te 600-1200 rpm, ā, ka kitea te haruru o te wira urungi.
Whakaterenga ngoikore: He uaua ki te neke ake i te 3000 rpm te tere o te miihini ina piki ana, ā, ka puta pea ngā oro pakū, te paoa mā rānei i te paipa hau (nā te korenga o te tahunga kāore i oti).
Mōrearea o te whakaweto i te mīhini i te wā e taraiwa ana: Tērā pea ka motu te hiko i te wā e taraiwa tere ana, ā, ka uru te ECU ki te aratau tiaki ka whakaweto kaha, he tino morearea tēnei.
Ngā mahi pūnaha me ngā tohu whakatūpato
Te rahunga o te pūnaha hiko:
Ka korekore noa iho ngā mahi pēnei i te mana tere, te tīmatanga-mutu aunoa, me te aukati hau.
Kei te kā tonu, kei te wheriko tonu te rama hapa, ā, ka whakahohehia e ētahi tauira ngā whakaoho hononga EPS/ABS.
Ngā tukunga rerekē me te whakapaunga wahie: Ka puta tonu te paoa ma me te kakara rite ki te penehīni, ka ripoatahia e te pūoko hāora he waehere hapa o te kore taurite o te ranunga wahie, ā, ka tino piki ake te whakapaunga wahie.
Ngā rerekētanga o te kaha o te hapa
He hapa iti: He ngoikore te waka i te pikinga, he puhoi te urupare a te whakateretere, engari kāore te mahi a te mana e tino rerekē.
He hapa nui: Kāore e taea te tīmata, ā, ka puta he tangi i te mea e pā ana te piston ki te takirere (i ngā tauira tawhito).
Ina rahua te pūoko tūnga o te porowhita o te miihini, ka whakaatu te waka i ngā tohu pēnei i te tīmatanga rerekē, te ngaronga o te mana, te wiri nui haere, me te rama hapa e kā ana, penei:
Tīmatanga rerekē
Mā te ngaronga o te tohu pūoko ka pōrearea te wā mura me te wā werohanga wahie, ka puta mai i ēnei āhuatanga:
Uauatanga o te tīmatanga makariri: He maha ngā nganatanga hei whakakā, ā, i ngā wā tino kino, kāore e taea te tīmata.
Te roanga o te wā tīmatanga: Ka roa ake te wā hurihuri o te mīhini, ā, tera pea ka rangona ngā oro rerekē.
Ngā raruraru taraiwa
Nā te hapa ka kore taurite te pūnaha hiko, ā, ko ngā tohu noa ko:
Te whakaterenga ngoikore: He puhoi te urupare o te piki, o te hipa rānei, ā, me pēhi katoa te pētera whakaterenga kia tere ake ai.
Wiriweri mangere: Ka wiri nui te mīhini ina tū, ā, he mārama te haruru o te urungi, o te nohoanga rānei.
Te tukunga paowa mā: Ka puta te paowa mā mai i te paipa putanga hau nā te kore o te tahunga oti. Te pikinga o te whakapaunga wahie: Nā te kore tika o te whakahaere weronga wahie, ka heke te pai o te whakamahinga o te wahie.
Te rahunga o te pūnaha hiko
Ka puta he tauhohenga mekameka mai i ngā tohu pūoko rerekē:
Ka kā te rama hapa: Kei te kā tonu, kei te kanapa tonu rānei te rama hapa o te miihini i runga i te papaaho.
Rahunga mahi: Kāore e taea te whakamahi i te pūnaha whakahaere tere me te pūnaha aukati hau.
Te tūponotanga o te whakaweto i te mīhini: Tērā pea ka whakaweto ohorere te mīhini i a ia e tere ana, ka tū hei tūponotanga mō te haumaru.
