He aha te mea he chopper waka?
Ko te whakawhiti ā-wāhanga motuka, e pā ana ki te actuator i roto i te pūnaha wā takirere rerekē (VVT), e mōhiotia ana hoki ko te kaiwhakahaere ā-wāhanga camshaft, ko te kaiwhakahaere wā rānei. Ehara i te mea he taputapu "whakawhiti ā-wāhanga" motuhake engari he wāhanga matua o te pūnaha wā takirere miihini, e kawenga ana mō te whakarerekē hihiri i ngā wā whakatuwheratanga me te kati o ngā takirere whakauru, putanga rānei i runga i te tere miihini, te kawenga, me ētahi atu āhuatanga whakahaere, kia pai ai te putanga mana, te penapena wahie, me te mahi tukunga.
Ko tana mahi matua he whakarerekē i te koki āhuahanga i waenga i te camshaft me te crankshaft, kia tutuki ai te wā takirere taurangi tonu. Kāore e taea e te wā takirere pumau tuku iho te urutau ki ngā āhuatanga whakahaere katoa, engari ka taea e te nekehanga āhuahanga te whakatutuki i te "whakatikatika mohio":
I ngā tere iti me ngā kawenga iti: Whakaterea te whakatuwheratanga o te takirere whakauru hei whakanui ake i te rōrahi whakauru, hei whakarei ake i te taipana me te maeneene.
I ngā tere tiketike me ngā kawenga teitei: Whakaroahia te katinga o te takirere whakauru, me te whakamahi i te pānga ātete whakauru hei whakapai ake i te pai o te utu me te whakaputa mana.
Ngā momo me ngā mātāpono mahi o te nekehanga ā-wāhanga
Whakawhiti ā-wāhanga waipēhi (auaha)
Ka peia e te pēhanga hinu miihini mā roto i ngā rotor ā-roto momo mata, āhua poraka rānei, ka huri i te tūranga whanaunga i waenga i te camshaft me te wira mekameka. Ka whakahaere te takirere whakahaere hinu (OCV) i te ara iahiko hinu e ai ki te whakahau a te ECU kia tutuki ai te neke whakamua, te whakaroa rānei i te wā.
Hanganga: Kei roto ko te stator, te rotor, te rūma waipēhi, te pine raka, me te puna whakahoki, me ētahi atu.
Ngā Here: Ka pāngia te tere me te tika o te whakarerekētanga e te pēhanga me te pāmahana o te hinu miihini, ā, i te nuinga o te wā ka taea anake te whakarerekē mai i te "wāhanga tīmatanga" i te huarahi kotahi.
Whakawhiti ā-wāhanga hiko (hangarau hou)
Ka peia tika e te motuka, hei whakarite i te rerekētanga tere hurihuri i waenga i te camshaft, te wira mekameka, me te motuka mā te hanganga miihini e toru-tuaka hei whakatutuki i te whakatikatika wāhanga tika ake me te tere ake.
Ngā Painga: He tere ake te urupare, he tika ake te whakahaere, kāore e pāngia e ngā āhuatanga o te hinu miihini, ā, he kaha ake te urutau.
Ngā Huakore: He nui ake te utu i te momo waipēhi, e whakamahia ana i ēnei wā i roto i ngā waka papai.
Ngā whakamāramatanga whānui kua whakamāramahia
Pūoko nekehanga ā-wāhanga ≠ pūoko nekehanga ā-wāhanga: Ko te pūoko nekehanga ā-wāhanga (pēnei i te pūoko tūranga camshaft) te "kanohi" e kite ana i ngā tūranga takirere, ko te pūoko nekehanga ā-wāhanga ia te "ringa" e whakahaere ana i te whakatikatika.
Kaitahuri ā-wāhanga ≠ kaitahuri auau, kaitahuri tohu rānei: Ko ētahi rauemi ehara i te motuka e kī ana ko te "kaitahuri ā-wāhanga" e pā ana ki te whakatikatika ā-wāhanga tohu hiko, kāore e pā ana ki te hanganga miihini o te miihini. Whakarāpopototanga
Ko te mīhini tapatapahi waka tētahi o ngā hangarau matua mō ngā miihini hou kia eke ki te whai huatanga teitei, te tiaki taiao, me te mahi teitei. Ka arotauhia e ia te wā whakatuwheratanga me te katinga o te takirere, kia pai ake ai te "manawa" o te miihini i raro i ngā āhuatanga mahi rerekē. I tēnei wā, ko te momo waipēhi te momo matua, ko te momo hiko kei te piki haere te rongonui o te ao āpōpō.
Tērā pea he hē te kupu "chopper" i roto i te ao motuka. Ko tā tātou e kōrero nei ko te kaiwhakahaere hiko (e mōhiotia ana ko te kaiwhakahaere hiko), koinei te wāhanga matua o te pūnaha utu o te waka, ā, ko ia te kawenga mō te whakaū i te putanga hiko o te miihini hiko. Mēnā ka rahua, ka pā tika ki te pūtake hiko me te mahi a te waka.
Anei ngā āhuatanga noa, ngā take, me ngā otinga mō ngā hapa o te kaiwhakahaere hiko o te waka:
Ngā Āhuatanga Hapa Matua:
- Rama tohu pākahiko rerekē: Kei te kā tonu, kei te kanapa tonu rānei te rama tohu pākahiko (utu) i runga i te papaaho, koinei te tohu whakatūpato tino tika, e tohu ana kāore te pūnaha utu e mahi tika ana.
- Ngaohiko pākahiko rerekē:
- Ngaohiko iti (i raro i te 12V): Ka kore e ranea te utunga o te pākahiko, ka uaua ai te tīmata i te waka, te ngoikore o ngā rama o mua, te mahi hē o ngā taputapu hiko, tae atu ki te whakaweto ohorere o te miihini i te wā e taraiwa ana.
- Ngaohiko teitei (neke atu i te 14.5V): Ka nui rawa te utu o te pākahiko, ka tere ake te pau o te electrolyte i roto i te pākahiko, ka pupuhi, ka pakaru, ā, i ngā wā kino, ka pā mai pea te mōrearea o te pahūtanga o te pākahiko.
- Te hekenga o te mahi a te waka: Nā te kore pumau o te hiko, ka raru pea te mahi a te waeine whakahaere miihini (ECU), ka hua ake te wiri o te miihini, te kore e tere te whakatere, te kore pumau te tere, tae atu ki te whakaweto ohorere o te miihini.
- Te rahunga o ngā taputapu hiko: Tērā pea ka mahi pōturi ngā rama waka, ngā pūnaha oro, ngā matapihi, me ētahi atu, ka pāngia e te kanapa rerekē, ka pakaru rānei nā te hiko kore pumau.
Ngā Take Hapa Noa:
- Te rahunga o ngā wāhanga hiko ā-roto: Tērā pea ka pakaru, ka tuwhera rānei ngā transistors pānga-mara (FET) me ngā transistors Darlington rānei i roto i te kaiwhakahaere nā te nui rawa o te ngaohiko, te wera rawa, te koroheketanga rānei, koinei te tino take o te kore pumau o te ngaohiko (he tiketike rawa, he iti rawa rānei).
- Ngā āhuatanga taiao: Ka tere ake te tawhito o te pūnaha whakahaere nā te nui o te pāmahana i roto i te wāhanga miihini, te haumākū, me te taraiwa roa i runga i ngā rori pūkeko.
- Ngā rerekētanga o te ngaohiko i roto i te pūkaha hiko: Ina kore e pumau te ngaohiko putanga o te pūkaha hiko, ina tino rerekē rānei te kawenga, ka nui ake te taumahatanga ki runga i te kaiwhakahaere, ka mahi pinepine, ā, ka kino pea.
- Ngā raruraru waea: Mā ngā mono hononga e kore e rere, e waikura rānei, ngā aho hononga pakaru, poto rānei, ka kore pea te kaiwhakahaere e mahi tika.
Ngā Tikanga Tātaritanga me te Otinga:
- Whakataunga tuatahi: Tuatahi, tirohia te āhua o te rama tohu utu i runga i te papaaho, ka ine i te ngaohiko i waenga i ngā pito pākahiko me te mita maha (i te wā e oma ana te miihini). Me noho te ngaohiko noa i waenga i te 13.8V me te 14.5V. Mena he iti rawa, he teitei rawa rānei te ngaohiko, ka taea te whakatau ko te kaiwhakahaere hiko, ko te whakaputa hiko rānei te hapa.
- Tātaritanga ngaio: E taunakihia ana kia toro atu ki tētahi toa whakatika waka ngaio. Ka whakamahia e ngā tohunga hangarau ngā taputapu tātaritanga motuhake hei pānui i ngā waehere hapa, ā, ka tirotirohia whānuitia te whakaputa hiko, te kaiwhakahaere, me te ara iahiko utu katoa kia tika ai te kimi i te pūwāhi hapa.
- Mahere whakatika:
- Whakakapia te kaiwhakahaere hiko: Mō ngā kaiwhakahaere hiko, mēnā kua whakaūtia te pakaru, ko te whakakapi tika te otinga tere me te pono rawa atu.
- Tirohia ngā waea: I mua i te whakakapi i te kaiwhakahaere hiko, me whakarite kei te pai te āhua o ngā raina hononga me ngā mono kia kore ai e pakaru te wāhanga hou nā ngā raruraru waea.
- Tirohia te pūkaha hiko: I ētahi wā, ka puta pea ngā hapa o te pūkaha hiko (pēnei i ngā paraihe, ngā whakatikatika) hei raruraru whakahaere, nō reira me tirotiro ngātahi.
Kia mōhio mai: Ko te "poro hiko" e whakahuatia ana i runga i te ipurangi e whakamahia ana i roto i ngā waka tauira hiko, i ngā waka rererangi rānei, ā, he wāhanga tino rerekē i te kaiwhakahaere whakaputa hiko o te waka. He "kaiwhakahaere" anō hoki kei roto i te pūnaha hauhautanga o te waka, engari ko tana mahi he whakahaere i te whakatuwheratanga me te katinga o ngā pūhau hau, ā, kāore e pā ana ki te pūnaha utu. Hei whakarite i te haumaru o te taraiwa, ki te puta tētahi o ngā tohu o runga ake nei, me tirotiro tonu e te tohunga. Kaua e taraiwa me te waka he.
