He aha te mahi a te pūoko camshaft motuka
He mahi nui tā te pūoko tūnga camshaft i roto i te miihini motuka, ko te mahi matua he kohikohi i te tohu tūnga camshaft ka whakauru ki te waeine whakahaere hiko (ECU) hei whakatau i te wā mura me te wā werohanga wahie. Mā te kite i te tūnga hurihuri o te camshaft, ka whakatau te pūoko i te wā whakatuwheratanga me te wā kati o te takirere, ā, ka tutuki te mana whakahaere tika o te miihini.
Ko te kaupapa mahi o te pūoko tūnga camshaft e ahu mai ana i te hangarau whakaawe hikohiko, te hangarau whakaawe whakaahua-hiko rānei. Ina huri te camshaft, ka kitea e te pūoko he pūnga, he koki rānei i roto i te camshaft, ā, ka puta he tohu hiko e rite ana. I muri i te whiwhinga i ēnei tohu, ka whakatauhia e te ECU te wā mura me te wā werohanga wahie mā te tatau me te tukatuka, kia tika ai te whakahaere i te miihini.
He mea nui te tika me te pono o ngā pūoko tūranga camshaft ki te mahi a te miihini me te penapena wahie. Mēnā ka hē te pūoko, ka arahi pea ki te mura hē, te heke o te penapena wahie, ā, tera pea ka kore e mahi tika te miihini. Nō reira, he mea tino nui te tirotiro me te tiaki i te pūoko tūranga camshaft i ia wā.
He wāhanga nui te pūoko camshaft, e whakamahia ana hei kite i te tūranga me te tere o te camshaft, kia pai ai te mahi a te miihini. Ko te Camshaft Sensor, e mōhiotia ana ko te Camshaft Position Sensor (CPS) ko te Cylinder Identification Sensor (CIS) rānei, ko tana mahi matua ko te kohikohi i ngā tohu tūranga o te camshaft valve. Ka tukuna ēnei tohu ki te Wāhanga Whakahaere Hiko (ECU). Mai i ēnei tohu, ka taea e te ECU te tautuhi i te TDC pēhanga o te rango 1 mō te whakahaere werohanga wahie raupapa, te whakahaere wā mura me te whakahaere whakahekenga.
Hanganga me te mātāpono mahi
He maha ngā momo pūoko tūranga camshaft, tae atu ki te photoelectric me te aukume aukume. Ko te nuinga o te pūoko photoelectric he kōpae tohu, he kaihanga tohu me te tohatoha, ā, ka whakaputa tohu mā te diode emitting light me te transistor photosensitive. Ka whakamahia e te momo aukume aukume te pānga Hall, te mātāpono rānei o te aukume aukume hei whakaputa tohu, e wehea ana ki te momo Hall me te momo magnetoelectric.
Tūnga tāutanga
Ko te pūoko tūnga camshaft te mea e tāutahia ana i te pito o mua o te taupoki camshaft, ki te ritenga atu o te pito o mua o te camshaft intake me te camshaft exhaust. Mā tēnei hoahoa ka taea e te pūoko te kohi tika i te tohu tūnga camshaft.
Te mahi hapa me te pānga
Ki te kore e pai te pūoko o te camshaft, ko ngā tohu noa ko te uaua ki te tīmata i te waka, te uaua ki te whakakī hinu, te whakaroa rānei i te wā e wera ana, te nui haere o te wahie e pau ana, te kore e ranea te mana me te kore tere o te whakatere. Ko ēnei tohu e puta mai ana i te kore e taea e te ECU te whakahaere tika i te werohanga wahie me te wā mura.
