He aha te pūoko camshaft motuka?
Ko te pūoko tūnga camshaft o te motuka (CPS) he taputapu e whakamahia ana hei kite i te tūnga me te koki o te camshaft, e tuku tohu ana ki te ECU (Engine Control Unit) hei whakahaere i ngā tawhā matua o te miihini pēnei i te wā mura, te wā werohanga wahie, me te whakahaere pahūtanga.
Mahi matua
Te tūnga o te rango: Mā te kimi i te tūnga o te camshaft, ka whakatauhia te pokapū mate o runga kōpeketanga (BTDC) o te piston rango tuatahi kia tika ai te whakahaere werohanga wahie me te mura.
Tohu tukutahi: Hei tohu whakahaere matua mō te whakahaere mura, ka whakarite kia mahi ia rango o te miihini i roto i te raupapatanga.
Te kaupapa mahi
Te whakaputa tohu: Kei roto i te pūoko he diode tuku-mārama (LED) me te phototransistor. Mā roto i ngā kōhao tuku-mārama me ngā wāhanga ārai-mārama o te kōpae tohu, ka whakaputahia ngā tohu pāhekoheko taumata teitei me te taumata iti.
Momo tohu
Tohu Ne: E whakaata ana i te tūranga o te porowhita hurihuri, ā, e 360 ngā pātere e puta ana i ia hurihanga.
Tohu G: E whakaata ana i te tūranga o te camshaft, e whakaputa ana i te 6 ngā pāorooro mō ia hurihanga (e rite ana ki te koki hurihanga o te crankshaft 120°).
Ngā momo noa
Momo whakaahua-hiko: Te whakamahi i ngā huānga whakaahua-aro hei kimi i ngā kōhao e tuku mārama ana i te kōpae tohu.
Momo whakapūtanga aukume: Ka wehea ki te momo Hall (tohu kaha pumau) me te momo aukume hiko (ka rerekē te kaha i runga i te tere hurihuri).
Pānga hapa
Ngā āhuatanga o te hapa: Tērā pea ka kore e tīmata te mīhini, ka heke te mana, ka piki ake te whakapaunga wahie, ka pāorooro rānei.
Ngā tauira noa: Hei tauira, he takirua ngā camshaft o te Audi Q5 o te tau 2015, ā, e rua ngā pūoko e hiahiatia ana mō te aroturuki motuhake.
Ina hē te mahi a te pūoko camshaft o te motuka, ka puta ngā tohu pēnei i te uaua ki te tīmata, te heke o te mana, te nui haere o te kai wahie, te wiri o te tinana, me te rama whakatūpato e mura ana. Ka puta pēnei:
Youdaoplaceholder0 Tīmatanga rerekē : Kāore te miihini e mura, he uaua rānei ki te tīmata. Tērā pea he maha ngā nganatanga kia angitu ai. Ka puta pea tēnei i roto i ngā āhuatanga miihini makariri me te wera.
Youdaoplaceholder0 Take whakaputa mana : te whakaterenga ngoikore, te puhoi o te urupare a te pūkaha, me te korenga o te mana i te wā e taraiwa ana, ahakoa te wiri o te tinana.
Youdaoplaceholder0 Te hekenga o te penapena wahie : Kua tino piki ake te whakapaunga wahie nā te kore e taea e te ECU te whakahaere tika i te nui o te weronga wahie, ka hua ake te tahunga wahie kāore i oti.
Youdaoplaceholder0 Mahi kore pumau : Kāore te tere o te miihini i te pumau, ā, e kitea ana te wiri i te wā e noho mangere ana. Ka kaha ake te wiri i raro i te kawenga nui. Tērā pea ka pāngia ētahi waka e te oho o te taraiwa, e te tūnga ohorere rānei i te wā e whakamahana ana.
Youdaoplaceholder0 Tohutohu hapa : Kei te mura tonu te rama hapa miihini i runga i te papaaho (pērā i ngā waehere hapa OBD P0340-P0344), e tohu ana kua kitea e te pūnaha tētahi tohu rerekē.
Mena ka puta ngā tohu o runga ake nei, me tirotirohia te miihini, me whakatika hoki i te wā tika kia kore ai e pakaru te miihini.
I muri i te korenga o te mahi a te pūoko tūnga o te camshaft, kāore e taea e te waka te oma tika. Mā te taraiwa kaha ka kino pea te miihini, ka tūpono hoki he tūponotanga haumaru pērā i te tūnga o te motuka i te wā e taraiwa ana. Me whakatika tonu.
Te pānga o ngā hapa ki te kaha taraiwa
Ko te pūoko tūnga camshaft tētahi wāhanga matua o te pūnaha whakahaere miihini, e tuku ana i ngā tohu ā-wāhanga camshaft ki te ECU (Electronic Control Unit) hei whakahaere tika i te raupapa mura, te wā werohanga wahie, me te pehi pahūtanga. Kia pakaru, kāore e taea e te ECU te tautuhi tika i te tūnga o te rango, ka hua ake te korenga o te whakahaere miihini, ā, kāore e taea e te waka te pupuri i te mahi noa. E whakaatu ana i ēnei āhuatanga:
Youdaoplaceholder0 He uaua ki te tīmata, kāore rānei e taea te tīmata : Whai muri i te rahunga o te pūoko, me whakawhirinaki te ECU ki te tohu tūranga o te crankshaft hei whakatau ā-kore i te tūranga o te camshaft, ka whakaroa i te tukutahitanga o te mura me te werohanga wahie. I te tīmatanga makariri, ka hiahiatia pea he maha ngā nganatanga, ka rahua katoa rānei.
Te tūnga ohorere o te mīhini i te wā e taraiwa ana: Ina koa i raro i ngā āhuatanga wera, taumaha rānei, ka mate ohorere te mīhini nā te korenga o te mana whakahaere, ka piki ake te tūponotanga o ngā aituā.
Youdaoplaceholder0 Putanga mana iti : Ka uru te ECU ki te aratau tiaki hapa (aratau pikopiko), ka whakawhāiti i te tere o te waka (pēnei i te 80km/h) ka whakakore i ētahi mahi, ka ngoikore te whakatere me te uaua ki te piki pari.
Ngā tohu noa i puta mai i tētahi hapa mahi
I muri i te pakaru o te pūoko tūnga o te camshaft, ka whakaatu tonu te waka i ngā āhuatanga e whai ake nei, e whakaū ana i te koretake o te taraiwa:
Te tere kore pumau me te wiri nui : Kāore te ECU e whakarite i te wā whakatuwheratanga me te katinga o te takirere, ka hua ake he kore taurite i waenga i te nui o te whakauru me te whakaputanga. Kei roto te miihini i te āhua rite ki te "rango ngaro", me te nui o ngā huringa o te tere hurihuri.
Youdaoplaceholder0 Te hekenga o te penapena wahie : Ko te wā tika o te werohanga wahie ka arahi ki te tahunga koretake, ka piki ake te whakapaunga wahie mā te 10% ki te 15%, ā, ka puta pea te paoa pango mai i te paipa hau i te wā kotahi.
Ka mau tonu te rama hapa: ka whakaatuhia e te papatohu he whakatūpato hapa miihini (pēnei i te waehere P0011, P0340 rānei), e tohu ana i tētahi hapa pūnaha.
Te mōrearea o te taraiwa ā-ture
Ki te kore e arohia te hapa, ā, ka haere tonu te waka, ka puta pea ngā pānga kino e whai ake nei:
Youdaoplaceholder0 kino ā-mīhini : Ka taea e te wā mura hē te whakararu, te huri rānei i te porowhita. Mā te mahi roa ka kino pea ngā wāhanga matua pērā i ngā piston me ngā tokotoko hono, ka nui ake ai ngā utu tiaki.
Youdaoplaceholder0 Te rahunga o te pūnaha tukunga : Ka nui rawa ngā tukunga o te CO me te HC nā te korenga o te tahunga, ka ārai pea i te kaitahuri hiko-toru, ka takahi hoki i ngā ture tiaki taiao.
Youdaoplaceholder0 Ka kaha ake ngā tūponotanga haumaru : Ka pā tika te tūnga o te motuka, te motumotu rānei o te hiko i te wā e taraiwa ana ki ngā pūnaha pēnei i te āwhina parai me te āwhina urungi, ā, ka tū hei mōrearea ki te haumaru o te taraiwa.
