He aha te kaiwhakahaere wāhanga waka?
Ko te kaiwhakahaere ā-wāhanga motuka he taputapu e whakarerekē ana i te wā takirere mā te whakarerekē i te koki ā-wāhanga, ā, e whakamahia ana hei whakapai ake i te mahi a te miihini. Ko tana mahi matua he whakarerekē i te wā whakatuwheratanga me te wā kati o ngā takirere kia rite ki te tere me te kawenga o te miihini, kia pai ake ai te whakaputanga mana me te penapena wahie.
Hanganga me te mātāpono mahi
Ko te kaiwhakahaere ā-wāhanga he mea hanga i te tinana kaiwhakahaere ā-wāhanga, he pītiti porotaka, he motuka, me ētahi atu, ā, ka whakatikatikaina te ā-wāhanga o te porotaka mā te pūnaha waipēhi, mā te puku motuka rānei. Hei tauira, ka honoa e te kaiwhakahaere ā-wāhanga hiko te porotaka me te pītiti mā te tikanga whakarerekētanga tere tuaka-toru, ā, ka peia e te motuka te whakatikatika o te rerekētanga ā-wāhanga hei whakatutuki i te whakatikatika hihiri o te wā takirere.
Ngā horopaki tono matua
Ko te nuinga o te wā e whakamahia ana i roto i ngā pūnaha wā takirere rerekē (pēnei i te VVT), e kapi ana i ngā whakaritenga o ngā āhuatanga whakahaere rerekē o te miihini. Hei tauira, ka taea e te kaiwhakahaere wāhanga whakauru te whakapai ake i te pai o te mura, i te mea ka taea e te kaiwhakahaere wāhanga putanga te whakaiti i te pokanoa o te hau putanga.
Ko ngā whakarerekētanga ā-wāhanga waka e whakamahia ana hei whakarerekē i ngā tawhā o te ara iahiko whakakorikori mā te whakarerekē i te tohu, ka puta he nekehanga ā-wāhanga i roto i te tohu kawe hei hanga i tētahi ngaru whakarerekē-ā-wāhanga. Ko te nuinga o ēnei e whakamahia ana mō te whakarerekētanga tohu me te tuku i roto i ngā pūnaha hiko.
Mahi matua
Youdaoplaceholder0 Te whakarerekētanga tohu : Mā te whakarerekē i ngā tawhā pēnei i te inductance me te capacitance o te ara iahiko resonant, ka whakarerekētia te āhua o te tohu kawe kia tutuki ai te whakarerekētanga āhua o te tohu.
Mana whakahaere ara iahiko Youdaoplaceholder0 : Ka whakamahia i roto i ngā pūnaha hiko hei whakahaere i te pumau o te ngaohiko, hei tauira, te pupuri i te ngaohiko putanga o te whakaputa hiko i te uara kua whakatauhia (pēnei i te 14V) kia mau tonu ai te mahi noa o ngā taputapu hiko.
Mahi tiaki Youdaoplaceholder0 : Ina kitea he nui rawa te iahiko utu, ina puta rānei he rere whakamuri, ka tere te motu i te ara iahiko hei ārai i te nui rawa o te utu o te pākahiko, i te kino rānei o ngā taputapu.
Te rerekētanga mai i te kaiwhakahaere waka
Ko ngā kaiwhakahaere āhuahanga e arotahi ana ki te tukatuka tohu me te whakahaere ara iahiko, ko ngā kaiwhakahaere motuka ia e aro nui ana ki te pumau o te ngaohiko me te tiaki i te aukume nui i roto i ngā pūnaha hiko. He rerekē ngā āhuatanga tono o ngā mea e rua, engari e rua ngā mea e uru ana ki te whakahaere i ngā tawhā ara iahiko me ngā tikanga tiaki.
Ko te kaupapa mahi o te kaiwhakahaere ā-wāhanga motuka e ahu mai ana i te pūnaha waipēhi, i te puku rānei o te motuka. Mā te whakarerekē i te tūranga whanaunga i waenga i te camshaft me te crankshaft, ka whakarerekētia te wā takirere (arā, te wā e tuwhera ai, e kati ai ngā takirere).
Te kaupapa o ngā whakarerekētanga ā-wāhanga waipēhi
Hei tauira, ko te pūnaha OCV VVT e mau ana ki te taha. Ko ōna wāhanga matua ko te kaiwhakahaere ā-wāhanga me te takirere whakahaere hinu (OCV). Ka whakatikatika te kaiwhakahaere ā-wāhanga i te tūranga whanaunga i waenga i te porotiti camshaft me te rotor mā roto i te rūma waipēhi, ā, ka whakahaere te takirere whakahaere hinu i te pēhanga waipēhi kia rite ki ngā āhuatanga whakahaere o te miihini. Ina iti te kawenga, katia te takirere whakauru i mua; ina teitei te kawenga, whakaroahia te katia o te takirere whakauru hei whakapai ake i te putanga mana.
Te kaupapa o te kaiwhakahaere hiko
E toru ngā tuaka o te kaiwhakahaere hiko: ka honoa te tuaka tuatahi ki te camshaft, ka peia te tuaka tuarua e te motuka, ā, ka honoa te tuaka tuatoru ki te sprocket. Ka tutuki i te motuka te whakahaere i te āhua mā te whakarerekē i te rerekētanga tere. Ina pumau te koki wā pai, ka huri tahi ngā tuaka e toru. Ina whakarerekētia te āhua, ka peia e te motuka te tuaka kia tere ake, kia puhoi ake rānei.
E rua ngā momo e hiahiatia ana he pūoko hei aroturuki i ngā tūranga o te poroka crankshaft me te poroka camshaft, me te whakahaere i ngā mahi a te actuator mā te ECU.
Ka taea e ngā hapa o te kaiwhakahaere waka (e pā ana ki te kaiwhakahaere hiko) te arahi ki te ngaohiko rerekē, te uaua ki te tīmata me ētahi atu raruraru. Ko ngā āhuatanga me ngā take motuhake e whai ake nei:
Ngā āhuatanga noa
Te rerekētanga ngaohiko o Youdaoplaceholder0
Ka taea e te whakaputanga hiko nui rawa te arahi ki te utu nui rawa o te pākahiko, me te neke atu pea o te ngaohiko ki te 14V, ka tere ake te koroheketanga o te pākahiko, ka pakaru pea. Ina kore e ranea te whakaputanga hiko, ka iti iho pea te ngaohiko i te 10V, ka uaua te tīmata me te ngoikore o te whakaterenga.
Ngā hapa e pā ana ki te pākahiko Youdaoplaceholder0
Ki te kore e rite te rama tohu pākahiko (e kā tonu ana, e kanapa tonu ana rānei), ka poto te ora o te pākahiko. Mēnā he nui rawa ngā āhuatanga, kāore pea e taea te penapena hiko.
Te hekenga o te mahi miihini Youdaoplaceholder0
Ki te wiri te mīhini, ki te ngoikore te tere, ki te tū rānei te motuka, me tirotirohia, me whakatika hoki i te wā tika.
Te take o te hapa mahi
Te piki me te heke o te ngaohiko o Youdaoplaceholder0
Nā te kore pumau o te ngaohiko putanga o te miihini hiko (pērā i te piki me te heke o te tere o te miihini tīhiera me ngā panonitanga nui o te kawenga) ka huri pinepine te kaiwhakahaere, ka tere ake te tawhito o ngā wāhanga.
Youdaoplaceholder0 Te kawenga ā-mīhini nui rawa atu
Mā te mahi taumaha roa (pērā i te noho mangere, te turuturu hinu rānei ki te rohe whakaputa hiko) ka piki ake te kawenga mahi a te kaiwhakahaere.
Te pakeketanga o te wāhanga Youdaoplaceholder0
Ka pakaru, ka tuwhera rānei ngā ara iahiko o roto o te kaiwhakahaere (pērā i ngā FET, ngā transistor Darlington), ka ngaro te mana whakahaere i te ngaohiko.
