He aha te mea he chopper waka?
Ko te whakawhiti ā-wāhanga motuka, e pā ana ki te whakawhiti ā-wāhanga i roto i te pūnaha wā takirere rerekē (VVT), he wāhanga matua o te pūnaha tereina takirere o te miihini. E whakamahia ana hei whakarite hihiri i ngā wā whakatuwheratanga me ngā wā kati o ngā takirere whakauru, putanga rānei hei whakapai ake i te mahi a te miihini, te penapena wahie, me ngā taumata tukunga i raro i ngā āhuatanga whakahaere rerekē.
Ko tana mahi matua he whakarerekē i te koki āhua i waenga i te camshaft me te crankshaft i runga i ngā āhuatanga tūturu pēnei i te tere o te miihini, te kawenga, me te pāmahana, ā, ka taea ai te wā takirere hurihuri tonu. Kāore e taea e ngā miihini me te wā takirere pumau te whakataurite i te taipana tere-iti me te mana tere-tiketike, engari mā te nekehanga āhua, mā te whakatikatika atamai, ka taea e te miihini te whakatutuki i te pai o te whakauru me te whakaputanga hau i roto i ngā āhua rerekē.
Whakaahuatanga poto o te kaupapa mahi
Ko te nekehanga ā-wāhanga ka tāutahia ki te pito o mua o te camshaft, ā, ka honoa ki te mekameka wā, ki te pūre rānei. Ko tōna hanganga taketake he rotor e hono pūmau ana ki te camshaft, me te stator e hono ana ki te pūre wā. Ka hangaia he raupapa o ngā kōhao hinu hiri i waenganui i te rotor me te stator.
Whakawhiti ā-wāhanga waipēhi (tino kaha): Ko te hinu miihini, i raro i te pēhanga o te papu hinu, ka tukuna tika ki te rūma whakamua, ki te rūma whakaroa rānei o te whakawhiti ā-wāhanga mā te takirere whakahaere hinu (takirere OCV). Mā te whakahaere i te pēhanga hinu, ka huri te rotor e pā ana ki te stator, ā, ka huri i te ā-wāhanga o te camshaft. Hei tauira, mā te tuku hinu ki te rūma whakamua ka taea te whakatuwhera wawe i te takirere hei whakanui ake i te taipana tere-iti; mā te tuku hinu ki te rūma whakaroa ka taea te whakaroa i te whakatuwheratanga o te takirere hei whakanui ake i te mana tere-tiketike.
Whakawhiti ā-wāhanga hiko (hangarau hou): Hei tauira, ko te whakawhiti ā-wāhanga hiko i whakawhanakehia e LuK e whakamahi ana i tētahi hanganga miihini e toru-tuaka e peia ana e te motuka, e hono tika ana i te camshaft, te pulley, me te motuka. Mā te whakahaere tika i te tere o te motuka, ka tutuki te hurihanga whanaunga i waenga i te camshaft me te pulley, ā, ka whakatikatika i te wā takirere. Kāore tēnei hanganga i te pēhanga hinu miihini, he tere ake te tere urupare, he tika ake te whakahaere, ā, kāore e pāngia e te matotoru hinu miihini pāmahana iti.
Ngā painga matua
• Whakapai ake i te putanga mana: Whakapai ake i te koki taupatupatu o te takirere i ngā tere miihini teitei, whakanuia te rahinga whakauru, me te whakanui ake i te mana miihini.
• Whakapai ake i te penapena wahie: Whakatutukihia te pānga huringa Miller mā te whakaroa i te katinga o te takirere whakauru i ngā kawenga iti, ka whakaiti i ngā ngaronga papu.
• Whakaitihia ngā tukunga: Mā te tahunga tino pai ka whakaitihia te whakaputanga o ngā hau kino (pērā i te CO, NOx, me te HC).
• Whakapai ake i te urutau: Ina koa ko te whakawhiti āhua hiko, he kaha ake te urutau ki te pāmahana miihini me ngā huringa āhua mahi.
Te whakamārama i ngā māramatanga whānui
• Kaitahuri ā-wāhanga ≠ pūoko ā-wāhanga: Ko te kaitahuri ā-wāhanga te kaiwhakaoho, e kawenga ana mō te "whakatikatika"; ko te pūoko ā-wāhanga ia (pēnei i te pūoko tūnga camshaft) te tikanga pūoko, e kawenga ana mō te "aroturuki" i te tūnga tuturu o te camshaft me te tuku anō i te tohu ki te waeine whakahaere miihini (ECU) hei hanga i tētahi mana whakahaere porowhita-kati.
• Whakawhiti ā-wāhanga ≠ kaiwhakahaere ā-wāhanga taurangi camshaft: Ko te kupu whakamutunga tēnei e whakamahia ana e ngā waitohu pēnei i a Audi mō tā rātou rautaki whakahaere pūnaha VVT, ā, ko tōna wāhanga matua ko te whakawhiti ā-wāhanga.
Hei whakarāpopototanga, ko te whakawhiti ā-wāhanga motuka tētahi o ngā hangarau matua mō ngā miihini hou kia tutuki ai te mahi whai hua, ma, me te mahi teitei. Kei te whanake haere tōna whanaketanga mai i te momo waipēhi tuku iho ki tētahi momo hiko tika ake, pono ake hoki.
I roto i te ao motuka, ko te kupu "phase shifter" e pā ana ki ngā wāhanga mahi rerekē e rua, ā, ko ō rātou mahi motuhake e whakawhirinaki ana ki te pūnaha e whakamahia ana.
• Pūnaha whakawhiti ā-wāhanga VVT (pūnaha wā takirere rerekē): He wāhanga matua tēnei i roto i te pūnaha whakahaere o te mīhini. Ko tana mahi matua he whakarite hihiri i te wāhanga hurihuri o te camshaft i runga i ngā āhuatanga whakahaere tūturu o te mīhini (pēnei i te tere me te kawenga). Mā te whakarerekē i ngā wā whakatuwheratanga me te katinga o ngā takirere whakauru me/ranei te putanga hau, ka taea te whakapai ake i te pai o te whakaurunga me te tukanga tahunga i roto i te rango, ka tutuki ai te pānga o te whakarei ake i te mana o te mīhini, te whakapai ake i te penapena wahie, me te whakaiti i ngā tukunga putanga hau. Kaiwhakahaere pūnaha hiko motuka (kaiwhakahaere ngaohiko): Ko tēnei wāhanga te kawenga mō te aroturuki me te whakahaere i te ngaohiko putanga o te mīhini whakaputa waka. Nā ngā huringa o te tere o te mīhini, ka rerekē te tere o te mīhini whakaputa, ka puta ai te ngaohiko putanga kore pumau. Ka whakahaere te kaiwhakahaere ngaohiko i te aukume aukume i roto i te mīhini whakaputa kia mau tonu te ngaohiko putanga i te uara kua whakatauhia (tata ki te 14.0V). Ka tiakina pai e tēnei ngā taputapu hiko o runga mai i ngā rerekētanga ngaohiko, ā, he mahi āna ki te aukati i te aukume utu nui me te tapahi i te aukume whakamuri (rerenga whakamuri) hei tiaki i te pākahiko me te mīhini whakaputa.
