Incazelo yobuchwepheshe kanye nencazelo yephutha P2447

Ikhodi yephutha P2447 ihlobene nesistimu ye-emissions. Iphampu yomjovo womoya yesibili iqondisa umoya kumagesi akhipha umoya ukuze kuncishiswe ukukhishwa. Idonsa umoya wangaphandle futhi iwuphoqelele ngokusebenzisa ama-valve okuhlola indlela eyodwa amabili eqenjini ngalinye le-exhaust.

Iphutha libonisa ukuthi iphampu yesistimu yomjovo wesibili womoya, efakwe kwezinye izimoto, ibambekile. Inhloso yesistimu ukuphoqa umoya wasemkhathini ungene kusistimu yokukhipha umoya ngesikhathi sokuqala okubandayo.

Lokhu kusiza ukusha kwama-molecule e-hydrocarbon angashiswanga noma ashiswe kancane kumfudlana wegesi ephumayo. Kuvela ngenxa yokuvutha okungaphelele ngesikhathi sokuqala okubandayo, lapho injini isebenza ngengxube yamafutha omoya anothiswe kakhulu.

Amasistimu omoya wesibili ngokuvamile aqukethe iphampu yomoya enamandla amakhulu ngendlela ye-turbine kanye ne-relay ukuvula nokuvala injini yepompo. Kanye ne-solenoid ne-valve yokuhlola ukulawula ukugeleza komoya. Ngaphezu kwalokho, kunamapayipi ahlukahlukene namapayipi afanele isicelo.

Ngaphansi kokusheshisa okunzima, iphampu yomoya iyacishwa ukuze kuvinjwe ukugeleza emuva kwamagesi okukhipha umoya. Ukuze uzihlole, i-PCM izosebenzisa uhlelo lomjovo womoya wesibili futhi umoya omusha uzoqondiswa ohlelweni lokukhipha umoya.

Izinzwa zomoya-mpilo zibona lo moya omusha njengesimo esibi. Ngemuva kwalokho, ukulungiswa kwesikhashana kokunikezwa kukaphethiloli kufanele kwenzeke ukuze kunxephezele ingxube ethambile.

I-PCM ilindele ukuthi lokhu kwenzeke phakathi nemizuzwana embalwa ngesikhathi sokuzihlola. Uma ungaboni ukwanda kwesikhashana kwe-fuel trim, i-PCM ihumusha lokhu njengokungasebenzi kahle ohlelweni lwesibili lomjovo womoya futhi igcina ikhodi ye-P2447 enkumbulweni.

Izimpawu zokungasebenzi kahle

Uphawu oluyinhloko lwekhodi ye-P2447 yomshayeli yi-MIL (Isibani Sesikhombi Esingasebenzi kahle). Ibizwa nangokuthi Injini Yokuhlola noma umane nje "ukuhlola kuvuliwe".

Angase futhi abukeke kanje:

Isibani sokulawula "Hlola injini" sizokhanyisa kuphaneli yokulawula (ikhodi izogcinwa kumemori njengokungasebenzi kahle).
Kwezinye izimoto zaseYurophu, ukukhanya okuxwayisa ngokungcola kuyakhanya.
Umsindo wepompo yomoya ngenxa yokuguga kwemishini noma izinto zangaphandle empompini.
Injini ayisheshi kahle.
Injini iyakwazi ukucebe kakhulu uma kungena umoya omningi exhaust manifold.
Ngezinye izikhathi kungase kungabi khona izimpawu naphezu kwe-DTC egciniwe.

Ubunzima bale khodi abuphezulu, kodwa imoto cishe ayinakuphumelela ukuhlolwa kokukhishwa kwegesi. Kusukela lapho iphutha le-P2447 livela, ubuthi bokuqeda buzokhula.

Izizathu zephutha

Ikhodi P2447 ingase isho ukuthi inkinga eyodwa noma ngaphezulu kwezilandelayo yenzekile:

Ukudluliselwa kwepompo yomoya yesibili okunephutha.
Ama-valve okuhlola amaphampu anephutha.
Inkinga ngokulawula i-solenoid.
Ukuqhekeka noma ukuvuza kwamapayipi noma imigudu yomoya.
I-Carbon ifaka kumapayipi, amashaneli nezinye izingxenye.
Ukungena komswakama empompini nasenjinini.
Ukuphuka noma ukuphazamiseka kokunikezwa kwamandla enjini yepompo ngenxa yokungaxhumeki kahle noma izintambo ezilimele.
Ifuse yepompo yomoya yesibili ivuthelwe.
Ngezinye izikhathi imbangela i-PCM embi.

Uyixazulula kanjani inkinga noma usethe kabusha i-DTC P2447

Ezinye izinyathelo eziphakanyisiwe zokuxazulula inkinga ukulungisa ikhodi yephutha P2447:

Xhuma isithwebuli se-OBD-II kusokhethi yokuxilonga yemoto futhi ufunde yonke idatha egciniwe namakhodi wamaphutha.
Lungisa noma yimaphi amanye amaphutha ngaphambi kokuqhubeka nokuxilonga ikhodi engu-P2447.
Hlola izintambo zikagesi nezixhumi ezihlobene nephampu yomoya yesibili.
Lungisa noma shintsha noma yiziphi izingxenye ezimfushane, eziphukile, ezilimele noma ezigqwalile njengoba kudingeka.
Hlola ukudluliselwa kwepompo yomoya yesibili.
Hlola ukumelana nephampu yomoya yesibili.

Ukuxilongwa nokuxazulula izinkinga

Ikhodi P2447 isethwe uma ungekho umoya wangaphandle wokushisa ama-hydrocarbon amaningi kusistimu yokukhipha umoya ekuqaleni okubandayo. Lokhu kubangela ukuthi i-voltage esenzweni ye-oxygen yangaphambili ingaweli ezingeni elishiwo.

Inqubo yokuxilonga idinga ukuthi injini ibanda; Ngokufanelekile, imoto imile okungenani amahora ayi-10-12. Ngemuva kwalokho, udinga ukuxhuma ithuluzi lokuxilonga bese uqala injini.

I-voltage esenzwa yomoya-mpilo yangaphambili kufanele yehle ngaphansi kwamavolthi angu-0,125 cishe kumasekhondi angu-5 kuya kwangu-10. Iphutha ohlelweni lwesibili lomoya lizoqinisekiswa uma i-voltage ingehli kuleli nani.

Uma amandla kagesi angehli aze afike ku-0,125V kodwa ungezwa iphampu yomoya isebenza, hlola wonke amapayipi, imigqa, amavalvu, nama-solenoid ukuze avuze. Futhi qiniseka ukuthi ubheka wonke amapayipi, imigqa namavalvu ukuze uthole izithiyo ezifana ne-carbon buildup noma okunye ukuvimba.

Uma iphampu yomoya ingavuliwe, hlola wonke ama-fuses afanelekile, ama-relay, izintambo, kanye ne-pump motor ukuze uqhubeke. Faka esikhundleni noma lungisa izingxenye ezinokukhubazeka njengoba kudingeka.

Uma wonke amasheke eseqedile kodwa ikhodi ye-P2447 iphikelela, i-exhaust manifold noma ikhanda le-cylinder kungase kudingeke ukuthi kukhishwe. Ukufinyelela kumachweba wesistimu ukuhlanza amadiphozithi ekhabhoni.

Yiziphi izimoto okungenzeka zibe nale nkinga?

Inkinga ngekhodi P2447 kungenzeka emishinini ehlukahlukene, kodwa kukhona njalo izibalo lapho brand leli phutha lenzeka kaningi. Nalu uhlu lwabanye babo:
