Inzwa yokugeleza komoya, eyaziwa nangokuthi imitha yokugeleza komoya, ingenye yezinzwa ezibalulekile zenjini ye-automobile electronic fuel injection.Iguqula ukugeleza komoya ohogeliwe kube isignali kagesi futhi iyithumele ku-electronic control unit (ECU).Njengenye yezimpawu eziyisisekelo zokunquma umjovo kaphethiloli, iyinzwa ekala ukugeleza komoya enjinini.Inzwa yokugeleza komoya yakwa-VW ayiphephile futhi inokwethenjelwa kuphela, kodwa futhi inezinzuzo zokusebenza okuzinzile, ukuguquguquka nokulungisa kalula.Ngamafuphi, kuyisinqumo esingcono.
Inzwa yokugeleza komoya isetshenziselwa ukukala ikhwalithi yomoya ogeleza emoyeni wenjini.Lokhu kubalulekile ekubaleni ukuthi ungakanani uphethiloli okufanele wengezwe ukuze kuzuzwe isilinganiso esifanele se-air-fuel ratio (AFR).I-AFR ekahle ingu-14.7:1 (amaphawundi angu-14.7 omoya: amaphawundi angu-1.0 kaphethiloli), kodwa i-AFR yangempela ihlukile.Ukusheshisa kungase kudinge i-AFR ifike ku-12:1, futhi ngezinye izikhathi ukuhamba ngomkhumbi kungase kube phansi kuze kube ngu-22:1.Uma inzwa ye-MAF yonakalisiwe, imojula yokulawula injini (ECM) ayikwazi ukubala umjovo wamafutha ngendlela efanele, okungase kubangele izinkinga ezinkulu emotweni.

7 izimpawu ezimbiVW inzwa yokugeleza komoya
Kunezimpawu ezimbalwa zokwehluleka kwezinzwa ze-MAF, kodwa akuzona zonke izimpawu ezisobala:
- Hlola ukuthi ukukhanya kwenjini kuvuliwe yini: Ukusebenza nesekhethi amakhodi okuxilonga angase ahlobane ngokuqondile nenzwa ye-MAF, kodwa ukulungiswa kukaphethiloli namakhodi omlilo ongashayi eceleni kungaxhunyaniswa nenzwa ye-MAF.
- Ukusheshisa iphutha: Uma uhlangabezana nezinkinga lapho usheshisa kuthelawayeka noma ithrafikhi, kungase kube ngenxa yenkinga yenzwa ye-MAF, futhi i-ECM ingase ikhawulele umjovo.
- Isivinini sokungenzi lutho: Uma lingekho inani elifanelekile likaphethiloli, kunzima ukuzuza isivinini sokungenzi lutho esibushelelezi.Uma kunenkinga ngenzwa ye-MAF, injini ingase ingasebenzi kahle, ikakhulukazi uma ingenzi lutho.
- Umnotho ongemuhle kaphethiloli: Inzwa ye-MAF akudingeki yehluleke ngokuphelele ukuthinta ukonga kukaphethiloli.Uma i-ECM ingalungile, kungase kwengezwe uphethiloli ongadingekile, okubangela ukonga kukaphethiloli okubi.
- Intuthu emnyama yokukhipha umoya: Kwezinye izimo, i-ECM ingase ibe minyene kangangokuthi kuphuma intuthu emnyama lapho ephuma khona.Lokhu kungase futhi kulayishe ngokweqile isiguquli se-catalytic.
- Ukungabaza noma ukuhlinzwa: Ngesikhathi sokusheshisa noma ukuhamba ngomkhumbi, ungathola ukungabaza noma amandla angavamile angazelelwe, angase aphazamise.
- Kunzima ukuqalisa: Injini idinga uphethiloli owengeziwe ukuze iqale kunokulinda, kodwa uma isignali yenzwa ye-MAF igwegwile, i-ECM ingase ingayaleli umjovo kaphethiloli owanele ukuze iqale injini ngokushesha.
Lezi zinkinga azisho njalo ukuthi inzwa yakho ye-MAF inephutha.Ukuvuza kwevacuum, izihlungi zomoya ezivalekile, umoya okhipha umoya okhawulelwe, iziguquli ze-catalytic ezivalekile, noma amapayipi okukhipha alimele kungase kube ngenxa yekhwalithi ephansi yenzwa ye-MAF, ngakho-ke sicela uhlole isistimu yokuthatha ukuze uqede lezo zinkinga kuqala.
Indlela yokulungisa okubiVW inzwa yokugeleza komoya?
Uma uhlelo lwakho lokungenisa umoya lusebenza kahle kodwa lusenezinkinga, ungazama izindlela ezilandelayo:
- Zithintithe uthuli.Vula ipayipi lokungenisa umoya bese ufaka isihlungi somoya esisha ukuze uvimbele ukungena kothuli esikhathini esizayo.
- Sebenzisa okokuhlanza.Isicoci esikhethekile senzwa ye-MAF singakwazi ukubhekana nanoma yikuphi ukungcola.
- Imisele esikhundleni.Uma lezi zinyathelo ezimbili zingasebenzi, ngokuvamile kulula ukushintsha inzwa yokugeleza komoya elula.
Ukuhlonza izinkinga zokusebenza kokushayela kuyinqubo yokuqeda.Qhathanisa izingxenye zemoto yakho namasignali amahle aziwayo ukuze uthole ukuxilonga okunembile nokulungisa ngokushesha.
Ukukhetha inzwa yokugeleza komoya engcono kwa-VW kusho isinyathelo esiyimpumelelo sokukhetha imoto engcono, ngakho kufanele uthole ifektri ethembekile nechwepheshile ye-VW air flow sensor.U-Yasen uyakwenza.Uma unentshisekelo kukho, wamukelekile ukuthintana nathi ukuze uthole isaphulelo samahhala.
