I-Boost Pressure (MAP) Inzwa: Indima, Ukusebenza, kanye Nentengo
Okuqukethwe
Inzwa ye-MAP noma inzwa ye-boost pressure isetshenziselwa ukukala umfutho womoya owudlayo ngenxa yezinto eziphikisayo. Isetshenziswa kakhulu ezimotweni zikadizili ezifakwe i-turbocharger, kodwa futhi itholakala kwezinye izimoto zikaphethiloli. Inzwa idlulisa amasignali kuyunithi yokulawula injini, eyisebenzisela ukulungisa umjovo kaphethiloli.
🔍 Iyini inzwa ye-MAP?
Le thuthukisa inzwa yokucindezela ebizwa futhi Inzwa ye-MAP, okufushane nge-Manifold Absolute Pressure. Indima yakhona ukukala ukucindezela komoya owuthathayo enjinini. Ibese idlulisela lolu lwazi kukhompyutha ukuze ilungise umjovo kaphethiloli.
Inzwa ye-MAP isetshenziswa ikakhulukazi ezimotweni zikadizili ezinawo i-turbocharger... Lokhu kuvumela ukutholakala komoya okungcono enjinini, amandla omlilo angcono futhi ngaleyo ndlela namandla engeziwe emotweni. Isebenza nge-turbine ecindezela umoya bese idala ukuthi umfutho ukhuphuke.
Yilapho i-boost pressure sensor iqala khona ukusebenza, okwenza kube nokwenzeka ukwazi umfutho womoya endaweni yokungena enjinini. Ngakho-ke, lokhu kuvumela umjovo ukuthi uguqulelwe kuye ngokuthi.
Itholakala kuphi inzwa ye-MAP?
Inzwa ye-MAP isetshenziselwa ukukala umfutho womoya owuthathayo wemoto. Ngakho-ke, itholakala enjinini ekuthatheni umoya. Uzoyithola eshubhu ukudla okuphindwe kaningi noma eduze nayo, exhunywe kumqoqi ngeshubhu eguquguqukayo.
⚙️ Isebenza kanjani inzwa ye-boost pressure?
Indima yenzwa ye-boost pressure, noma inzwa ye-MAP, iwukubona nokulinganisa umfutho womoya ekungeneni komoya kwemoto yakho. Itholakala ezingeni lomoya enjinini, isebenza nayo iyunithi yokulawula injini.
Inzwa ye-MAP inzwa ebizwa nge-magnetoresistive. Yenziwe nge-ceramic futhi inezinqamuleli zokulinganisa ezizwela ukucindezela. Bese bekhiqiza amasignali kagesi ezidluliselwa kukhompuyutha.
Lokhu kuvumela isibali ukuthi shintsha inani likaphethiloli ijovwe ukuze ithuthukise ingxube yomoya / kaphethiloli kanye nokusha kwenjini, okuvumela imoto ukuthi ihambe.
🚗 Yiziphi izimpawu zenzwa ye-HS MAP?
Njengoba inzwa ye-boost pressure idlala indima kusistimu yomjovo emotweni yakho, inzwa ye-MAP engalungile ingayilimaza. Inzwa ye-MAP enesici ingabonwa ngezimpawu ezilandelayo:
- Ukusetshenziswa kukaphethiloli ngokweqile ;
- Amandla enjini ayehla ;
- Qalisa izinkinga ;
- Izitebele nama-misfire ;
- Isibani senjini sivuliwe.
Kodwa-ke, lezi zimpawu azihlobene ngempela nenzwa ye-MAP futhi zingabonisa inkinga kwenye indawo kumjikelezo womjovo. Ngakho-ke, kunconywa ukwenza ukuzihlola hlola ukusebenza kwenzwa ye-boost pressure.
💧 Ngiyihlanza kanjani inzwa ye-MAP?
Ukuhlanza inzwa ye-MAP kwesinye isikhathi kuyadingeka uma ukungcoliswa ngokweqile kuphazamisa umjovo wemoto yakho. Khona-ke kufanele ivulwe, ihlakazwe futhi ihlanzwe ngomkhiqizo okhethekile noma umoya omhlophe. Nokho, qaphela ukuthi ungayikhiphi i-turbocharger emotweni.
Izinto:
- Umoya omhlophe
- Ibhuleki yokuhlanza
- Amathuluzi
Isinyathelo 1. Hlukanisa inzwa ye-MAP.
Hlola indawo yenzwa ye-boost pressure encwadini yakho yesevisi noma ku-Automotive Service Manual (RTA) yemoto yakho. Ivamise ukutholakala ngaphakathi noma eduze nendawo eningi ethathwayo.
Uma usuyitholile, qhubeka nokuyiqaqa ngokukhipha isixhumi noxhumano. Bese uqaqa izikulufu zokugcina inzwa ye-MAP bese uyisusa.
Isinyathelo sesi-2: hlanza inzwa ye-MAP
Ngemuva kokuthi inzwa ye-MAP ihlakaziwe, ungayihlanza. Ngalokhu, sikweluleka ukuthi usebenzise umkhiqizo okhethekile owenzelwe ukuhlanza izingxenye zikagesi. Ungasebenzisa futhi i-brake cleaner kanye / noma umoya omhlophe.
Isinyathelo sesi-3. Hlanganisa inzwa ye-MAP.
Qedela ukuhlangana kwenzwa ye-MAP ngokulandelana kwe-disassembly. Misa kabusha inzwa ye-boost pressure, uphinde uxhume izixhumi zayo futhi ekugcineni ulungise kabusha ikhava yenjini. Ngemuva kokuhlanza, qiniseka ukuthi injini yakho isebenza kahle.
👨🔧 Uyibheka kanjani inzwa ye-MAP?
Ukuhlolwa komsebenzi we-boost pressure sensor kwenziwa ngayo ithuluzi lokuxilonga ngokuzenzakalelayo... Ngokuyixhuma kusixhumi semoto yakho se-OBD, ungasihlola ngaso amakhodi wephutha kuboniswa uma ngempela kuyinkinga yenzwa ye-MAP.
Ngakho-ke, amakhodi amaningana abonisa ukungasebenzi kahle kwale nzwa nokucindezela komfutho, okuhlanganisa: I-P0540, i-P0234, ne-P0235, kanye namakhodi wephutha asukela ku-P0236 kuya ku-P0242.
Ungazama futhi ukuhlola inzwa yakho ye-MAP nge i-multimeter ihlola i-voltage kusixhumi sayo. Kumodi yamanje eqhubekayo, kufanele uthole ukufundwa okungaba ngu-5 V.
💰 Ibiza malini inzwa ye-MAP?
Intengo yenzwa ye-MAP iyahluka kakhulu ukusuka kumodeli nemoto. Ungazithola ku-inthanethi kusuka kuma-euro ayishumi nanhlanu, kodwa ngokuvamile kuzodingeka ubale kabusha okungenani 30 €... Nokho, intengo ingakhuphukela cishe 200 €.
Manje uyazi ukuthi inzwa ye-MAP yemoto yakho ngeyani! Njengoba elinye igama liphakamisa, inzwa ye-boost pressure ngakho-ke ikala umfutho womoya owuthathayo futhi ngaleyo ndlela idlala indima ebalulekile ekushiseni kwenjini yakho. Ngakho-ke, kufanele ihlanzwe noma ishintshwe uma kwenzeka ukungasebenzi kahle.
