He aha te pūoko ā-wāhanga
He mea nui ngā pūoko āwhata hei wāhanga hiko mō ngā motuka, ā, e whakamahia ana hoki i roto i ngā mara maha hei ine i ngā rahinga ā-tinana pēnei i te tūranga me te tere o ngā mea.
I roto i te mara o ngā motuka, e whakamahia ana hei kimi i te wā takirere o te miihini hei whakatau i te wā mura tino pai.
He maha ngā momo pūoko ā-wāhanga, e whakarōpūtia ana ki ngā momo aukume hiko me ngā momo Hall, e whakaputa ana i ngā tohu ngaru sine me ngā tohu ngaru tapawhā. I te nuinga o te wā, kei roto hoki i tēnei ngā pūoko whakaahua hiko me ngā pūoko aukume.
Ka whakaputa te pūoko hikohiko i ngā tohu o ngā taumata rerekē mā te hurihuri i te papa tohu me te tahuri, te whakaweto rānei i te phototransistor i runga i te tuku, te aukati rānei i te mārama.
Ka whakamahia e te momo Hall i roto i ngā pūoko aukume te pānga Hall, ko te momo magnetoelectric ia ka whakamahia te mātāpono o te aukume aukume. Ina huri te rotor tohu, ka puta he kaha hiko tauutuutu i roto i te koiri aukume nā te huringa o te ara iahiko aukume.
Ko tōna mātāpono mahi he whakatutuki i te mahi mā te kite i te tūranga me te koki hurihuri o te camshaft. Ka taea e te koiri kimi ā-roto te kite i ngā mea whakarewa e tata ana. Ina kore he mea whakarewa, ka haruru te ara iahiko LC, ā, ka piki te ngaohiko putanga. Ina whakatata mai he mea whakarewa, ka puta ngā iahiko hurihuri ki roto i te koiri kimi, ka huri te inductance o te koiri, ka rerekē te ara iahiko LC whakarara, ā, ka heke te ngaohiko putanga. He rite te rerekētanga ki te tawhiti o te mea whakarewa. Ka kitea te rerekētanga ā-wāhanga mā te ine i te rerekētanga ngaohiko putanga.
Ko te wā takirere e pā ana ki te koki e whakatuwheratia ai, e katia ai hoki ngā takirere whakauru me ngā takirere whakaputanga o te miihini e pā ana ki te hurihanga o te porowhita. He mea nui te wā takirere tika mō te mahi a te miihini, e pā ana ki te mana, te penapena wahie me ngā tukunga whakaputanga.
Ko te pūoko ā-wāhanga te kawenga mō te aroturuki i te tika o te ā-wāhanga o te tereina takirere. Ina puta he hapa, ka tangi te whakaoho, ā, ka tiaho te rama hapa o te miihini.
Ko ngā pūoko āhuahanga, arā, ko te kupu whānui mō ngā pūoko tūranga camshaft me ngā pūoko tūranga crankshaft, he pūtake nui mō te whakatau i te wā mura o te miihini.
Ka kitea e te pūoko wāhanga camshaft te tūranga hurihuri o te camshaft, ka whakauru i tētahi tohu ki te ECU, koinei te tohu matua mō te whakahaere mura.
Ka kitea e te pūoko tūranga o te toki porowhita te koki o te toki porowhita o te mīhini me te pokapū mate o runga o te piston, ā, ka tukuna ngā tohu ki te rorohiko mīhini hei whakahaere i te wā mura me te wā werohanga wahie. Koinei hoki te pūtake tohu mō te ine i te tere o te mīhini.
I ētahi atu mara, ka tukuna e ngā pūoko ā-wāhanga, e hangai ana ki te mātāpono o te ine ā-wāhanga, ngā tohu ki ngā mea, ā, ka tatau i ngā mōhiohio tūranga o ngā mea mā te ine i te rerekētanga ā-wāhanga i waenga i ngā tohu ka tukuna me ngā tohu whakaata.
He whānuitia te whakamahinga i roto i ngā mara pēnei i te aunoatanga ahumahi, te rererangi, te tiaki hauora, me te karetao, ā, ka taea te āwhina i te whakahaere whakatere motuhake o ngā karetao, te whakahaere whakatere o ngā waka kawe, me te tautuhi hauora, me ētahi atu.
Ko te pūoko ā-wāhanga he wāhanga matua o ngā pūnaha whakahaere miihini motuka hou, he mea tito mai i ngā pūoko tūranga crankshaft me ngā pūoko tūranga camshaft. Ko te pūoko tūranga crankshaft te kawenga mō te kohikohi i ngā tohu tere miihini me te koki crankshaft, e whakarato ana i te tohutoro wā mō te mura me te werohanga wahie. Mā te pūoko tūranga camshaft ka whakarite kia tika te whakahaere o te whakahaere werohanga wahie raupapa me te whakahaere pahūtanga mā te tautuhi i te tūranga o te pokapū mate o runga o te kōpeketanga rango [3] [8]. Ka mahi tahi ngā mea e rua mā te tukutahi ā-wāhanga, he mea tino nui i te wā tīmatanga, ā, me taurite tika te wā mura tuatahi [6]. Ka kiia tēnei rōpū pūoko he "pūoko ā-wāhanga" nā tana mahi whakahaere whānui i runga i te wāhanga tereina takirere me te wā mura.
Ka taea e te rahunga o te pūoko wāhanga te arahi ki te maha o ngā raruraru.
Ko te raruraru tuatahi ko te uauatanga o te tīmatanga o te mīhini. Me whakarato e te pūoko ā-wāhanga ki te ECU ngā mōhiohio mō te tūranga o te porowhita crankshaft, ā, ka tatau te ECU i te wā mura me te nui o te werohanga wahie i runga i ēnei mōhiohio. Mēnā ka hē te mahi a te pūoko ā-wāhanga, kāore e taea te whakarato i ngā mōhiohio tika. Kāore e taea e te ECU te whakahaere tika i te mura me te werohanga wahie, ka uaua ai te tīmatanga o te mīhini, ka kore rānei e taea.
Kātahi ka puta te noho pōturi. I raro i ngā āhuatanga noa, ka aroturukihia e te pūoko ā-wāhanga te tūranga o te toki porowhita, ka taea ai e te wae whakahaere miihini te whakarerekē i te wā mura me te nui o te kai e tomo ai te miihini kia pai ai te tere noho pōturi o te miihini. Kia kore e mahi tika te pūoko ā-wāhanga, ka hē ngā mōhiohio e tukuna ana ki te ECU, ā, ka rerekē te mana whakahaere a te ECU i te miihini. Nō reira, ka pōturi te tere noho pōturi, ā, ka puta pea ngā raruraru pēnei i te wiri o te noho pōturi me te tere hurihuri.
Ka ngoikore hoki te whakaterenga. Ina whakatere te waka, me whakarato e te pūoko ā-wāhanga ngā mōhiohio tika me te wā-tūturu pērā i te tūranga o te porowhita, kia taea ai e te ECU te whakarite wawe i ngā rautaki mura me te werohanga wahie kia tutuki ai ngā whakaritenga whakaterenga o te waka. Ina puta he hapa, he hē ngā mōhiohio, kāore e taea e te ECU te whakarite tika, ka pāngia te putanga mana o te miihini, ka ngoikore te whakaterenga, ā, ka puta pea he kare ā-roto, ka pā ki te wheako taraiwa.
Hei tāpiritanga, ka mura te rama hapa. Ina kitea e te pūnaha tātaritanga hapa o te motuka he rahunga o te pūoko ā-wāhanga, ka whakaohohia he waehere hapa, ā, ka mura te rama hapa o te miihini i runga i te papaaho, hei whakamahara i te rangatira motuka kei te raru te waka.
Hei whakamutunga, ka piki ake te whakapaunga wahie. Mēnā ka rahua te pūoko ā-wāhanga, kāore e taea e te ECU te whakahaere tika i te nui o te weronga wahie. Tērā pea he nui rawa, he iti rawa rānei te nui o te weronga wahie, ā, ka hua ake he tahunga kāore i oti, ā, kāore te wahie e huri pai hei mana, ā, ka piki ake te whakapaunga wahie.
Hei whakamutunga, he pānga nui ngā hapa o te pūoko ā-wāhanga ki ngā waka. Ina puta ngā raruraru o runga ake nei, me tirotiro wawe te pūoko ā-wāhanga, ā, ki te tika, me whakatika, me whakakapi rānei kia hoki ai te waka ki tōna āhua noa.
