Ukulawula kwenziwa kusetshenziswa inani lamadivayisi abizwa ngokuthi izinzwa. Bafunda izinkomba ezifanele futhi bazidlulisele ohlelweni lokulawula, olulungisa ukusebenza kwenjini.

Enye yezinto ezinjalo inzwa yomoya-mpilo.

Ifakwe exhaust manifold ngaphambi kwesiguquli se-catalytic.

Incazelo

Inzwa ye-oxygen i-VAZ 2114 iyithuluzi le-elekthronikhi eliqapha izinga lamagesi okukhipha umoya.

Igama layo lesibili, elilungile ngokobuchwepheshe, liyi-lambda probe. Isebenza njengengxenye ebalulekile yesistimu yokulawula ye-elekthronikhi.

Impilo yesevisi ye-lambda probe ingathinteka yilokhu:

• izimo zokusebenza;
• izinga likaphethiloli;
• isevisi ngesikhathi;
• ukuba khona kokushisa ngokweqile;
• ukusebenza kwenjini ende kwimodi ebucayi;
• ukulungiswa ngesikhathi kanye nokuhlanza i-probe.

Ngaphansi kwezimo ezijwayelekile zokusebenza, i-lambda probe ingasebenza iminyaka engu-7. Njengomthetho, ngalesi sikhathi imoto ingahamba amakhilomitha ayizinkulungwane ezingu-150.

Ukuqokwa

I-VAZ 2114 inzwa ye-oxygen iklanyelwe ukunquma umoya-mpilo kumagesi okukhipha umoya nomoya ozungezile. Ngemva kokunquma inani layo futhi idlulisele isignali, isistimu yokulawula i-electronic ithola ukuvutha okungaphelele kwengxube kaphethiloli enjinini.

Ngale ndlela, i-lambda probe isiza ukugcina ukusebenza kwenjini okubushelelezi nokuzinzile ngokusebenza okuqhubekayo kobuchwepheshe lapho kubhekene nezimo zokusebenza ezishintshayo.

Isimiso sokusebenza

Ibona umehluko phakathi kwakho kokubili bese ithumela isignali ehambisanayo ohlelweni lokulawula lwe-elekthronikhi.

I-Lambda probe VAZ 2114 iqukethe amayunithi alandelayo:

• uhlaka;
• i-heater kagesi;
• i-electrode yangaphandle;
• i-electrode yangaphakathi;
• i-ceramic insulator. Itholakala phakathi kwama-electrode;
• i-casing evikela i-electrode yangaphandle emiphumeleni enolaka yamagesi okukhipha amandla;
• isixhumi sokuxhuma.

I-electrode yangaphandle yenziwe ngeplatinum kanti i-electrode yangaphakathi yenziwe nge-zirconium. Ngenxa yezakhiwo ezihlukene zezinsimbi, inzwa ingenza imisebenzi yayo.

Isistimu yokukhipha umoya wenjini iyingxenye eshisa kakhulu, ngakho izingxenye ze-lambda probe zenziwe ngezinto ezimelana nokushisa okuphezulu ukuvimbela ukwehluleka ngaphambi kwesikhathi.

Isixhumi sokuxhuma i-lambda probe ohlelweni lokulawula i-elekthronikhi siqukethe izikhonkwane ezine:

I-pinout yabathintana nabo besixhumi kanye nenzwa ye-oxygen i-VAZ 2114 imi kanje:

Ikhompuyutha esebhodini inikeza i-voltage engu-0,45 V ngokuthintana kwamandla we-lambda probe.

Futhi, ngesikhathi sokusebenza kwenjini, i-voltage inikezwa ku-heater kagesi.

Ngemva kokuqala injini, ikhompuyutha esebhodini ayikunaki ukufundwa kwe-lambda probe. Ukusebenza kulawulwa ngokusekelwe ekufundweni kwezinye izinzwa: ukugeleza komoya omkhulu kanye nezinga lokushisa langaphakathi lenjini evuthayo, kanye nenzwa yokuvula i-throttle.

Lokhu kungenxa yokuthi i-heater kagesi ayikalethi inzwa ye-oxygen ezingeni lokushisa lokusebenza. Ilingana no-± 350 °C.

Lapho i-lambda probe ishisa ngokwanele, ingakwazi ukufunda imingcele edingekayo:

• i-electrode yangaphandle - imingcele yegesi yokuqeda;
• imingcele yangaphakathi - umoya wangaphandle.

Isignali edluliswa inzwa ingumehluko phakathi kwamanani amabili.

Ngokuqhathanisa inani le-oxygen endaweni eningi yokukhipha umoya nangaphandle, isistimu inquma izinga lokuvutha. Ngamanye amazwi, umsebenzi wenzwa ye-oxygen ukuthola ukusha okungaphelele kwengxube evuthayo.

Uma ikhompuyutha esebhodini ithola idatha ngokuchezuka kwenani le-oxygen, yenza izinguquko ekusebenzeni kwamanye amasistimu (isibonelo: ohlelweni lukaphethiloli noma ekushiseni, ukwenza lokhu ngokushesha noma kamuva). Ngakho, isinxephezelo ngeziphambeko ekusebenzeni kwenjini.

Ama-probes e-lambda akhiqizwa ngaphambili ku-VAZ-2114 awazange abe nomsebenzi wokuzifudumeza. Umkhiqizi akazange agcwalise umklamo wenzwa nge-heater kagesi. Ngakho-ke, nakuba amagesi e-exhaust engazange ashise i-lambda probe ekushiseni okusebenzayo, ikhompyutha esebhodini yacabangela ukufundwa kwezinye izinzwa. Kodwa ngesikhathi esifanayo, izinga lamagesi okukhipha umoya liye lehla kakhulu.

Ngesikhathi sokugunyazwa kwemithetho emisha yokuthutha emgwaqweni okuhloswe ngayo ukunciphisa izinga lokungcoliswa kwemvelo, umenzi washintsha umklamo we-lambda probe futhi waqala ukufaka ama-heater kagesi. Ngenxa yalokho, ukuqapha nokushintsha izinga lamagesi e-exhaust yezimoto kwaqala kudala ngaphambi kokufudumala kwemvelo kwenjini.
