- Ukwenziwa kwe-carbonization kubonakala ngokufaka okomile, okungacwebezeli, okuhlukanisa umswakama ocwebezelayo kawoyela.
- Ngokuvamile kubangelwa izingxube ezicebile (uphethiloli owedlulele) noma ukwehluleka ohlelweni lokushisa kanye nezinzwa.
- Ukuxilongwa kuyahlukahluka kuye ngokuthi inkinga ithinta wonke amasilinda (imbangela yomhlaba wonke) noma eyodwa kuphela (imbangela yendawo).
Ngiyaqiniseka ukuthi sekuke kwenzeka kuwe ngaphambili: ukhipha ama-spark plug emotweni yakho bese uthola ukuthi amnyama ngokuphelele futhi abukeka omile . Lesi simo, esaziwa ngokuthi i-carbonization, simane nje siwukuqongelela kwe-soot ku-insulator kanye nama-electrode, okubonisa ukuthi kukhona okungahambi kahle ngokusha nokuthi uphethiloli awushi kahle.
Into yokuqala okufanele uyiqonde ukuthi i-spark plug kulesi simo akuyona inkinga ngokwayo, kodwa iwuphawu lwenkinga ejulile . Ukuzishintsha nje ngezintsha akusizi ngalutho uma imbangela eyinhloko ingaxazululwa, njengoba inkinga izovela maduze nje, okubangela ukusha kwezimoto noma ezinye izinkinga zokusha ezingakushiya uvaleleke ngesikhathi esibi kakhulu.
Umehluko phakathi kokwenziwa kwe-carbonization kanye nokungcoliswa kukawoyela
Kuvamile kakhulu ukudida umbala omnyama we-spark plug, kodwa kukhona icebo elilula lokuthola umehluko. Ukufakwa kwe-carbonization kuveza i -deposit ebuthakathaka, eyomile, neyimpuphu , ejwayelekile yokusha okungaphelele. Ngokuphambene nalokho, uma ubona ukuthi i-spark plug iyacwebezela, imanzi, noma inamafutha, kubonisa ukungcola kwamafutha, okusho ukuthi i-lubricant ivuza egumbini lokusha.
Inkinga yengxube ecebile
Uma sikhuluma ngengxube ecebile, sisho ukuthi kunophethiloli omningi kakhulu futhi umoya awunele ukuze kushiswe kahle. Ngobuchwepheshe, lokhu kwenzeka lapho inani le-lambda lingaphansi kuka-1 (λ < 1). Uma unethuluzi lokuskena eliseduze, bheka amanani e-STFT kanye ne-LTFT; uma engemihle, ikhompyutha yemoto izama ukunciphisa inani likaphethiloli ngoba ithola ukuthi ingxube icebile kakhulu.
Qaphela izinzwa ze-oxygen noma ze-A/F. Ngezinye izikhathi, inzwa inganikeza ukufundwa okungalungile futhi ibangele i-ECU ukuthi ifake uphethiloli omningi kunokudingekile. Ngakho-ke, akukhuthazwa ukuxilonga inzwa ngokusekelwe kuphela kumbala we-spark plug, kodwa kunalokho ukuhlaziya lonke uhlelo.
Kungani kwenzeka i-carbonization? Izimbangela eziyinhloko
- Ukunikezwa kukaphethiloli: Ukucindezela okukhulu erelini likaphethiloli kungabangela ukuthi ama-injector alethe uphethiloli omningi kunalokho okufanele. Kungenzeka futhi ukuthi i-injector iyavuza noma inamathele, okwandisa ingxube ku-cylinder eyodwa kuphela.
- Izinzwa zomoya kanye nokushisa: Uma inzwa ye-MAF noma ye-MAP yehluleka, ukubalwa kokushaja komoya ngeke kube okunembile. Ngokufanayo, inzwa ye-ECT ekhombisa ukuthi injini ibanda kakhulu kunalokho eyikho ngempela izophoqa imoto ukuthi igcine isu lokucebisa ngokuqala ngokuzenzakalelayo kude kakhulu.
- Ukungena okuvinjelwe: Isihlungi somoya esingcolile kakhulu noma noma yikuphi ukuvinjelwa kokungena komoya kuzonciphisa umoya-mpilo otholakalayo, kuvimbele uphethiloli ukuthi ungashi ngokuphelele.
- Uhlelo lokushisa olungasebenzi kahle: Akukhona nje uphethiloli. Inhlansi ebuthakathaka, ikhoyili ene-insulation egugile, noma ukusebenzisa i-spark plug ene- Ububanzi bokushisa obungalungile kungabangela ukuthi ingxube ingashi ngokuphelele.
- Imikhuba yokushayela: Ukwenza uhambo olufushane kakhulu ngenjini ebandayo noma ukushayela njalo ngesivinini esiphansi kakhulu kusiza ukuqongelela kwalezi zinsalela zekhabhoni.
Indlela yokuxilonga inkinga ngokwephethini
Uma, lapho uhlola injini, uthola ukuthi wonke ama-spark plug amnyama ngokulinganayo , inkinga cishe itholakala kulo lonke uhlelo. Kulesi simo, kufanele uhlole ingcindezi kaphethiloli, isihlungi somoya, inzwa ye-lambda, kanye nokufundwa kokushisa kwenjini. Iskena se-OBD siyithuluzi lakho elingcono kakhulu lapha lokuqapha ama-counter omlilo ongalungile kanye nokulungiswa kukaphethiloli ngesikhathi sangempela.
Kodwa-ke, uma ipulaki elilodwa kuphela eliyilo mbala, inkinga itholakala kulowo silinda othize. Kulesi simo, kufanele uhlole i-fuel injector (ukumelana nephethini yokufutha), ikhoyili yokushisa, noma wenze ngisho nokuhlolwa kokucindezela nokuvuza . Ukulahlekelwa ukucindezela ngenxa yamavalvu agugile noma amasongo e-piston kungabangela ukuthi ipulaki ye-spark ibe mnyama noma ngabe ingxube yomoya nophethiloli ilungile.
Izinyathelo zokulungisa unomphela
Ukuhlanza i-spark plug kuyisisombululo sesikhashana, hhayi ikhambi. Isihluthulelo ukulungisa imbangela eyinhloko , kungakhathaliseki ukuthi lokho kusho ukushintsha i-injector evuzayo, ukushintsha i-temperature sensor, noma ukuhlanza i-input manifold. Uma inkinga isilungisiwe, kufanele kufakwe i-spark plug entsha ehlangabezana nezidingo zomenzi.
Ukuze kuqedwe inqubo, kunconywa ukuthi kusulwe amanani okuzivumelanisa nezimo e-ECU ngokulandela inqubo yemoto bese kwenziwa ukuhlolwa komgwaqo. Khumbula ukuthi ikhabhoni eqoqiwe ingadala indlela yokuhambisa umoya ku-insulator, iqondise amandla aye ekhasejini futhi ibangele ukusha kwezimoto ngaphansi komthwalo omkhulu noma ngesikhathi sokusheshisa.
Isihluthulelo sokuxazulula le nkinga sisekuqondeni ukuthi iphutha livamile noma lisendaweni, ngokuhlaziya idatha yesikena kanye nesimo somshini wenjini ngaphambi kokushintsha izingxenye ngokungahleliwe, ngaleyo ndlela kuqinisekiswe ukuthi ukushisa kuyaphumelela futhi futhi injini ithola ukusebenza kwayo okuhle kakhulu.
