Inhloso nezici zezinzwa ze-oxygen

Inzwa ye-oxygen iyithuluzi elikala inani le-oxygen ohlelweni lwe-exhaust. Amadivaysi amaningana anjalo afakwe ku-Priors, atholakala ngokushesha ngaphambi nangemva kwesiguquli se-catalytic. I-lambda probe yenza imisebenzi ebalulekile, futhi ukusebenza kwayo okulungile akuthinti nje ukunciphisa ukukhishwa okuyingozi emkhathini, kodwa futhi kwandisa ukusebenza kahle kweyunithi yamandla. Nokho, akubona bonke abanikazi bezimoto abavumelana nalo mbono. Futhi ukuze uqonde ukuthi kungani lokhu kunjalo, ukuhlaziywa okuningiliziwe kwamadivayisi anjalo kufanele kwenziwe.

Kuyathakazelisa! Inzwa ye-lambda probe ithole leli gama ngesizathu. Incwadi yesiGreki ethi "λ" ibizwa ngokuthi i-lambda, futhi embonini yezimoto imele isilinganiso somoya oweqile engxubeni yamafutha omoya.

Okokuqala, ake sinake inzwa ye-oxygen ku-Priore, etholakala ngemva kwe-catalyst. Esithombeni esingezansi, kukhonjiswa ngomcibisholo. Ibizwa ngokuthi i-Diagnostic Oxygen Sensor, noma i-DDK ngamafuphi.

Inzwa ye-oxygen No. 2 ku-Priora

Inhloso eyinhloko yesibili (ibizwa nangokuthi eyengeziwe) inzwa ukulawula ukusebenza kwe-catalyst yegesi yokukhipha. Uma lesi sici sinesibopho sokusebenza okulungile kwesihlungi segesi sokukhipha igesi, kungani-ke sidinga inzwa yokuqala, ebhalwe ngezansi.

Lawula inzwa ye-oxygen ngaphambili

Inzwa etholakala ngqo phambi kwe-catalyst isetshenziselwa ukunquma inani le-oxygen kumagesi okukhipha umoya. Ubizwa ngemenenja noma i-UDC ngamafuphi. Ukusebenza kahle kwenjini kuncike enanini le-oksijini ku-vapor ephumayo. Ngenxa yalesi sici, ukushiswa okuphumelelayo kakhulu kwamangqamuzana kaphethiloli kuqinisekisiwe futhi ukulimaza kwamagesi okukhipha amandla kuyancipha ngenxa yokungabikho kwezingxenye zikaphethiloli ezingashisiwe ekubunjweni kwawo.

Ukungena esihlokweni senhloso ye-lambda probe ezimotweni, kufanele wazi ukuthi idivayisi enjalo ayinqumi inani lokungcola okuyingozi ekukhishweni, kodwa inani le-oxygen. Inani layo lilingana ne- "1" lapho ukwakheka okuphelele kwengxube kufinyelelwa (inani elifanele libhekwa lapho u-1 kg womoya uwela ku-14,7 kg kaphethiloli).

Kuyathakazelisa! Ngendlela, amanani we-air-gas ratio yi-15,5 kuya ku-1, futhi injini ye-diesel 14,6 kuya ku-1.

Ukuze kuzuzwe imingcele ekahle, kusetshenziswa inzwa ye-oxygen.

Uma kukhona inani elikhulu le-oksijeni emagesi okukhipha, inzwa izodlulisela lolu lwazi ku-ECU (iyunithi yokulawula i-elekthronikhi), yona, izolungisa umhlangano wamafutha. Ungafunda kabanzi mayelana nenjongo yezinzwa ze-oxygen kuvidiyo engezansi.

Izici zokuklama kanye nesimiso sokusebenza kwezinzwa ze-oxygen: ulwazi oluthakazelisayo noluwusizo kakhulu

Umklamo kanye nesimiso sokusebenza kwenzwa ye-oxygen ulwazi oluzosiza hhayi kuphela kubanikazi bangaphambilini, kodwa nakwezinye izimoto. Phela, ulwazi olunjalo luzoba ukhiye futhi luzodlala indima ebalulekile ekuxazululeni izinkinga zemoto ngokuhlukana okuhlukahlukene. Ngemva kokuqiniseka ngokubaluleka kwalolu lwazi, ake siqhubekele ekucabangeni kwakho.

Kuze kube manje, kunolwazi oluningi mayelana nesimiso sokusebenza kwezinzwa ze-oksijini kanye nomklamo wazo, kodwa hhayi ngaso sonke isikhathi ukunakwa okwanele kukhokhwa kulolu daba. Kumele kuqashelwe ngokushesha ukuthi izinzwa ze-oxygen zihlukaniswa ngezinhlobo kuye ngokuthi uhlobo lwezinto ezenziwe ngazo. Nokho, lokhu akuthinti indlela osebenza ngayo, kodwa kubonakala ngokuqondile esisetshenziswa somsebenzi kanye nekhwalithi yomsebenzi. Ziyizinhlobo ezilandelayo:

1. I-Zirconium. Lezi yizinhlobo ezilula zemikhiqizo, umzimba owenziwe ngensimbi, futhi ngaphakathi kukhona i-ceramic element (i-electrolyte eqinile ye-zirconium dioxide). Ngaphandle nangaphakathi kwezinto ze-ceramic zimbozwe ngamapuleti amancane, ngenxa yokuthi ugesi ukhiqizwa. Ukusebenza okuvamile kwemikhiqizo enjalo kwenzeka kuphela lapho ifinyelela amazinga okushisa angama-300-350 degrees.
2. I-Titanium. Zifana ngokuphelele namadivayisi ohlobo lwe-zirconium, ahluke kuphela kuwo ngokuthi i-ceramic element yenziwe nge-titanium dioxide. Banempilo ende yesevisi, kodwa inzuzo yabo ebaluleke kakhulu ukuthi ngenxa ye-titanium refractoriness, lezi zinzwa zifakwe umsebenzi wokushisa. Izakhi zokushisa zihlanganisiwe, ngakho idivayisi ishisa ngokushesha, okusho ukuthi amanani engxube anembe kakhudlwana atholakele, okubalulekile lapho uqala injini ebandayo.

Izindleko zezinzwa azixhomeki kuphela ohlotsheni lwezinto ezenziwe ngazo, kodwa futhi nezici ezifana nekhwalithi, inani lamabhande (i-narrowband ne-wideband), nokuthi ubani umenzi.

Idivayisi ye-Lambda probe Iyathakazelisa! Amadivayisi avamile we-narrowband achazwe ngenhla, kuyilapho amadivaysi e-wideband ebonakala ngokuba khona kwamaseli engeziwe, ngaleyo ndlela athuthukise ikhwalithi, ukusebenza kahle nokuqina kwamadivayisi. Uma ukhetha phakathi kwezakhi ze-narrowband ne-wideband, okuthandayo kufanele kunikezwe uhlobo lwesibili.

Ukwazi ukuthi yiziphi izinzwa ze-oxygen, ungaqala ukufunda inqubo yomsebenzi wabo. Ngezansi isithombe, ngesisekelo ongakwazi ukuqonda ukuklama kanye nesimiso sokusebenza kwezinzwa ze-oxygen.

Lo mdwebo ubonisa izingxenye zesakhiwo ezilandelayo ezibalulekile:

• I-1 - i-ceramic element eyenziwe nge-zirconium dioxide noma i-titanium;
• I-2 no-3 - ulwelwesi lwangaphandle nangaphakathi lwe-casing yangaphakathi (isikrini), ehlanganisa ungqimba lwe-yttrium oxide oluboshwe nge-conductive porous platinum electrode;
• I-4 - othintana nabo abaphansi abaxhunywe kuma-electrode angaphandle;
• I-5 - othintana nabo besignali abaxhunywe kuma-electrode angaphakathi;
• I-6 - ukulingisa ipayipi yokukhipha lapho inzwa ifakwe khona.

Ukusebenza kwedivayisi kwenzeka kuphela ngemva kokuba sekushiselwe amazinga okushisa aphezulu. Lokhu kufezwa ngokudlula amagesi akhipha umoya ashisayo. Isikhathi sokufudumala cishe imizuzu emi-5, kuye ngenjini nezinga lokushisa elizungezile. Uma inzwa inezici zokushisa ezakhelwe ngaphakathi, khona-ke lapho injini ivuliwe, icala langaphakathi lenzwa liyashiswa ngaphezu kwalokho, elivumela ukuthi liqale ukusebenza ngokushesha. Isithombe esingezansi sibonisa lolu hlobo lwenzwa esigabeni.

Kuyathakazelisa! Ku-Priors, i-lambda probes yokuqala neyesibili isetshenziswa ngezinto zokushisa.

Ngemva kokushiswa kwenzwa, i-electrolyte ye-zirconium (noma i-titanium) iqala ukudala okwamanje ngenxa yomehluko ekubunjweni komoya-mpilo emkhathini nangaphakathi kokukhipha umoya, ngaleyo ndlela yenza i-EMF noma i-voltage. Ubukhulu balo mbane buncike esilinganisweni somoya-mpilo oqukethwe ku-exhaust. Ihluka kusuka ku-0,1 kuya ku-0,9 volts. Ngokusekelwe kulawa manani kagesi, i-ECU inquma inani le-oxygen ekukhishweni kokukhipha futhi ilungise ukwakheka kwamaseli kaphethiloli.

Manje ake siqhubekele phambili ekutadisheni isimiso sokusebenza kwenzwa yesibili ye-oxygen ku-Priore. Uma isici sokuqala sinesibopho sokulungiswa okulungile kwamaseli kaphethiloli, khona-ke okwesibili kuyadingeka ukulawula ukusebenza kahle kwe-catalyst. Inomgomo ofanayo wokusebenza nokuklama. I-ECU iqhathanisa ukufundwa kwezinzwa zokuqala nezesibili, futhi uma zihluka (idivayisi yesibili ibonisa inani eliphansi), khona-ke lokhu kubonisa ukungasebenzi kahle kwe-converter ye-catalytic (ikakhulukazi, ukungcola kwayo).

Umehluko phakathi kwe-Priory UDC kanye nezinzwa zomoya-mpilo we-DDC Kuyathakazelisa! Ukusetshenziswa kwezinzwa ezimbili ze-oxygen kubonisa ukuthi izimoto ze-Priora zihambisana nezindinganiso zemvelo ze-Euro-3 ne-Euro-4. Ezimotweni zesimanje, kungafakwa izinzwa ezingaphezu kwezi-2.

Kwenzekani emotweni lapho inzwa yomoya-mpilo ingasebenzi kahle: amakhodi amaphutha

Ukwehluleka kwenzwa ye-oxygen ezimotweni ze-Priora nezinye izimoto (sikhuluma nge-lambda probe yokuqala) kuholela ekwephulwa kokusebenza okuzinzile kwenjini yangaphakathi yomlilo. I-ECU, lapho lungekho ulwazi oluvela kunzwa, ibeka injini kumodi yokusebenza ebizwa ngokuthi izimo eziphuthumayo. Iyaqhubeka nokusebenza, kodwa izakhi zikaphethiloli kuphela ezilungiselelwe ngokwamanani ajwayelekile, azibonakalisa ngendlela yokusebenza okungazinzile kwenjini yomlilo yangaphakathi, ukwanda kokusetshenziswa kukaphethiloli, amandla ancishisiwe kanye nokwanda kokukhishwa okuyingozi emkhathini.

Ngokuvamile, ukuguqulwa kwenjini kumodi ephuthumayo kuhambisana nenkomba ethi "Hlola Injini", okusho ngesiNgisi ukuthi "hlola injini" (hhayi iphutha). Izimbangela zokungasebenzi kahle kwenzwa kungaba yizici ezilandelayo:

• gqoka ama-Lambda probes anensiza ethile, encike ezintweni ezihlukahlukene. Ama-Prior afakwe embonini enezinzwa ezijwayelekile ze-zirconium-band-band, insiza engadluli ku-80 km yokugijima (lokhu akusho nhlobo ukuthi umkhiqizo udinga ukushintshwa ngesikhathi sokugijima);
• ukulimala komshini - imikhiqizo ifakwe kwipayipi yokukhipha, futhi uma inzwa yokuqala ingahlangani nezithiyo ezihlukahlukene ezingase ziyithinte ngenkathi ushayela, khona-ke eyesibili ingathinteka kakhulu kubo ngokungabikho kokuvikelwa kwenjini. Oxhumana nabo kagesi bavame ukonakala, okufaka isandla ekudlulisweni kwedatha engalungile kukhompyutha;
• ukuvuza kwezindlu. Lokhu kuvame ukwenzeka lapho kusetshenziswa imikhiqizo okungeyona eyangempela. Ngokwehluleka okunjalo, ikhompuyutha ingase yehluleke, ngoba inani elingaphezu kwe-oksijini lifaka isandla ekunikezeni isignali engalungile kuyunithi, yona, engaklanyelwe lokhu. Kungakho kunganconywa ukukhetha ama-analogue ashibhile angewona awoqobo ama-lambda probes avela kubakhiqizi abangaziwa;
• ukusetshenziswa kwamafutha ekhwalithi ephansi, uwoyela, njll. Uma ukukhishwa kubonakala ngokuba khona komusi omnyama, ifomu le-carbon deposits ku-sensor, okuholela ekusebenzeni kwayo okungazinzile nokungalungile. Kulokhu, inkinga ixazululwa ngokuhlanza isikrini sokuzivikela.

Izimpawu zesici zokuhluleka kwenzwa ye-oxygen ku-Prior yilezi zibonakaliso ezilandelayo:

1. Isibonisi esithi "Hlola Injini" sikhanyisa kuphaneli yezinsimbi.
2. Ukusebenza okungazinzile kwenjini, kokungenzi lutho nangesikhathi sokusebenza.
3. Ukwenyuka kokusetshenziswa kukaphethiloli.
4. Ukukhishwa kwe-exhaust eyengeziwe.
5. Ukuvela kokulungiswa kwenjini.
6. Ukuvela kwamaphutha.
7. Ikhabhoni ifaka kuma-electrode ama-spark plugs.
8. Amakhodi ephutha ahambisanayo avela ku-BC. Amakhodi nezizathu zabo ezibalwe ngezansi.

Ukungasebenzi kahle kwezinzwa zomoya-mpilo kunganqunywa ukuba khona kwamakhodi ephutha ahambisanayo aboniswa kusikrini se-BC (uma etholakala) noma kuskena se-ELM327.

I-ELM327

Nalu uhlu lwalawa makhodi wephutha we-lambda probe (DC - inzwa ye-oxygen) ku-Priore:

• I-P0130 - Isignali yokuhlola ye-lambda engalungile n. No. 1;
• I-P0131 - Isignali ye-DC ephansi #1;
• I-P0132 - Isignali ye-DC yezinga eliphezulu No.
• I-P0133 - ukusabela kancane kwe-DC No. 1 ekucebiseni noma ekunciphiseni ingxube;

Lapho kuvela izimpawu ezingenhla, akufanele usheshe ushintshe i-DC emotweni ye-Priora. Hlola imbangela yokwehluleka kwedivayisi ngamaphutha ahambisanayo noma ngokuyihlola.

Indlela yokuhlola kahle inzwa ye-oxygen ngokusebenza kwe-Priora: imiyalelo

Uma kukhona izinsolo zokungasebenzi kahle kwe-lambda probe ngokwayo, hhayi isifunda sayo, akunconywa ukushesha ukuyishintsha ngaphandle kokuyibheka kuqala. Isheke lenziwa kanje:

1. Ku-KC efakwe emotweni, kuyadingeka ukunqamula isixhumi sayo. Lokhu kufanele kushintshe umsindo wenjini. Injini kufanele ingene kumodi ephuthumayo, okuwuphawu lokuthi inzwa iyasebenza. Uma lokhu kungenzeki, khona-ke injini isivele isesimweni esiphuthumayo futhi i-DC yamanje ayifani nesiqiniseko esingu-100%. Kodwa-ke, uma injini ingena kumodi yesimo esiphuthumayo lapho inzwa ivaliwe, lokhu akusona isiqinisekiso sokusebenza okugcwele komkhiqizo.
2. Shintshela umhloli kumodi yokulinganisa i-voltage (ubuncane bufika ku-1V).
3. Xhuma ama-probe omhloli kwabalandelayo abathintwayo: i-probe ebomvu kutheminali yocingo olumnyama ye-DC (ibophezelekile kusignali ethunyelwe kukhompuyutha), kanye nophenyo olumnyama lwe-multimeter kutheminali yocingo olumpunga.
4. Ngezansi iphinikhodi ye-lambda probe ku-Priore nokuthi yibaphi abathintwayo okuxhunywa kubo i-multimeter.
5. Okulandelayo, udinga ukubheka ukufundwa okuvela kudivayisi. Njengoba injini ifudumala, kufanele ishintshe ngo-0,9 V futhi yehle ibe ngu-0,05 V. Enjinini ebandayo, amanani kagesi okukhiphayo ahluka ukusuka ku-0,3 kuya ku-0,6 V. Uma amanani engashintshi, lokhu kukhombisa ukungasebenzi kahle kwe-lambda. Idivayisi idinga ukushintshwa. Naphezu kokuthi idivayisi inesici sokushisa esakhelwe ngaphakathi, ngemva kokuqala injini ebandayo, kungenzeka ukuthatha ukufundwa nokunquma ukusebenza okufanele kwesici kuphela ngemva kokufudumala (cishe imizuzu emi-5).

Kodwa-ke, kungenzeka ukuthi isici sokushisa senzwa sihlulekile. Kulokhu, idivayisi ngeke futhi isebenze kahle. Ukuze uhlole impilo yesici sokushisa, uzodinga ukuhlola ukumelana kwayo. I-multimeter ishintshela kumodi yokulinganisa ukumelana, futhi ama-probes ayo kufanele athinte ezinye izikhonkwane ezimbili (izintambo ezibomvu neziluhlaza okwesibhakabhaka). Ukumelana kufanele kube kusuka ku-5 kuya ku-10 ohms, okubonisa impilo yesici sokushisa.

Okubalulekile! Imibala yezintambo zokuzwa evela kubakhiqizi abahlukene ingase ihluke, ngakho-ke qondiswa ukuphina kwepulaki.

Ngokusekelwe ezilinganisweni ezilula, ukufaneleka kwamanje okuqondile kungahlulelwa.

Kuyathakazelisa! Uma kukhona izinsolo zokungasebenzi kahle kwe-DC, khona-ke ngemuva kwenqubo yokuqinisekisa, ingxenye esebenzayo kufanele ihlakazwe futhi ihlanzwe. Bese uphinda izilinganiso.

Uma i-Priora lambda probe isebenza, ngeke kube yinto engafanele ukuhlola isimo sesekhethi. Ukunikezwa kwamandla kwe-heater kuhlolwe nge-multimeter, ukulinganisa i-voltage koxhumana nabo besokhethi lapho idivayisi ixhunywe khona. Ukuhlola isifunda sesignali kwenziwa ngokubheka izintambo. Kulokhu, umdwebo oyisisekelo wokuxhuma ugesi uhlinzekwa ukusiza.

Umdwebo #1 Wenzwa Yomoya-mpilo Umdwebo #2 Wenzwa Yomoya-mpilo

Kumelwe kushintshwe inzwa enesici. Ukuhlolwa kwazo zombili izinzwa kuyefana. Ngezansi kunencazelo yesimiso sokusebenza kwamadivayisi kusukela emiyalweni yezimoto zePriora.

Incazelo ye-UDC Priora Incazelo ye-DDC Priora

Kubalulekile ukuqonda ukuthi lapho uhlola i-lambda nge-voltage ephumayo, ukufundwa okuphansi kubonisa ukweqisa komoya-mpilo, okungukuthi, ingxube ethambile inikezwa kumasilinda. Uma ukufundwa kuphezulu, khona-ke umhlangano wamafutha uyacetshiswa futhi awunawo umoya-mpilo. Lapho uqala i-motor ebandayo, ayikho isignali ye-DC ngenxa yokumelana okuphezulu kwangaphakathi.

Izici zokususa nokufaka esikhundleni senzwa ye-oxygen ku-VAZ-2170: izihloko namamodeli avela kubakhiqizi abahlukene be-Priora

Uma i-Priora ine-CD enephutha (kokubili eyinhloko neyesibili), kufanele ishintshwe. Inqubo yokufaka esikhundleni ayinzima, kodwa lokhu kungenxa yokufinyelela emikhiqizweni, kanye nobunzima bokuyikhulula, njengoba inamathela ohlelweni lokukhipha ngokuhamba kwesikhathi. Ngezansi kunomdwebo wedivayisi ye-catalytic enezinzwa zomoya-mpilo i-UDC ne-DDC efakwe ku-Priore.

Futhi ukuqokwa kwezakhi eziyisisekelo ze-catalyst kanye namadivayisi akhona emotweni ye-Priora.

Okubalulekile! I-Priora inama-lambda probes afana ncamashí, anenombolo yoqobo engu-11180-3850010-00. Ngaphandle, banomehluko omncane kuphela.

Izindleko zenzwa ye-oxygen yangempela ku-Priora cishe zingama-ruble angu-3000, kuye ngokuthi isifunda.

Inzwa ye-oxygen yasekuqaleni

Kodwa-ke, kukhona ama-analogues ashibhile, ukuthengwa kwawo akulungile ngaso sonke isikhathi. Kungenjalo, ungasebenzisa idivayisi yendawo yonke yakwa-Bosch, ingxenye yenombolo 0-258-006-537.

I-Priory inikeza ama-lambdas avela kwabanye abakhiqizi:

• I-Hensel K28122177;
• I-Denso DOX-0150 - uzodinga ukudayisa ipulaki, ngoba i-lambda inikezwa ngaphandle kwayo;
• I-Stellox 20-00022-SX - Uzodinga futhi ukudayisa ipulaki.

Ake siqhubekele ohlelweni oluqondile lokushintsha lesi sici esibalulekile ekwakhiweni kwemoto yesimanje. Futhi ngaso leso sikhathi kufanelekile ukwenza ukwehla okuncane futhi uphakamise isihloko esifana nokushintsha i-firmware ye-ECU ukunciphisa izinga lokuhambisana nemvelo ye-Euro-2. I-lambda yokuqala kufanele ifakwe ezimotweni zesimanje futhi kufanele ibe sesimweni esihle. Phela, ukusebenza kahle, ezinzile futhi ukonga injini kuncike kulokhu. Isici sesibili singasuswa ukuze singasishintshi, okuvame ukwenziwa ngenxa yezindleko eziphakeme kakhulu zomkhiqizo. Kubalulekile ukukuqonda lokhu, ngakho-ke ake siqhubekele enqubweni yokususa nokufaka esikhundleni senzwa ye-oxygen ku-Priore:

1. Inqubo ye-disassembly yenziwa kusukela endaweni yenjini. Ukuze usebenze, udinga i-wrench yendandatho ye-"22" noma ikhanda elikhethekile lezinzwa ze-oxygen.
2. Kungcono ukusebenzela ukuqaqa idivayisi ngemva kokufudumala injini evuthayo yangaphakathi, ngoba kuyoba yinkinga ukukhulula idivayisi uma kubanda. Ukuze ungashi, kunconywa ukuthi ulinde uhlelo lokukhipha umoya ukuze luphole kuze kufike ekushiseni kwama-degrees angu-60. Umsebenzi kufanele wenziwe ngamagilavu.
3. Ngaphambi kokukhipha, qiniseka ukuthi uphatha inzwa nge-WD-40 fluid (ungasebenzisa i-brake fluid) futhi ulinde okungenani imizuzu eyi-10.
4. Ipulaki Ikhutshaziwe
   
   
5. Isibambi sekhebula siyahlukaniseka.
6. Idivayisi ikhululiwe.
7. Ukushintshwa kwenziwa ngendlela ephambene yokususa. Lapho ufaka imikhiqizo emisha, kunconywa ukuthi ugcobe ngaphambili imicu yabo nge-graphite grease. Kubalulekile ukuqaphela ukuthi izinzwa No. 1 no-No. 2 zingashintshwa omunye nomunye uma kwenzeka eyokuqala iqala ukusebenza. Isici sokuqala sibaluleke kakhulu, ngoba nguye ophethe inqubo yokulungiselela izakhi zamafutha. Kodwa-ke, inzwa yesibili akufanele ishintshwe noma, ngoba ukwehluleka kwayo kuzoholela ekusebenzeni okungazinzile kwenjini yangaphakathi yomlilo. Ukuze ungathengi inzwa yesibili, ungathuthukisa "ubuchopho" ku-Euro-2, kodwa le nsizakalo izophinde ibize imali.

Umehluko phakathi kwezinqubo zokushintsha i-lambda ku-Priore 8 valve kanye ne-valve engu-16 ekufinyeleleni kumadivayisi. Ku-8-valve Ngaphambili, ukufika kuzo zombili izinhlobo zemikhiqizo kulula kakhulu kunama-valve angu-16. Ukukhipha i-lambda probe yesibili kungenziwa kokubili endaweni yenjini nangaphansi ukusuka embobeni yokuhlola. Ukuze ufike ku-RC yesibili usuka egumbini lenjini kuma-valve e-Priore 16, uzodinga i-ratchet enesandiso, njengoba kuboniswe esithombeni esingezansi.

Uma isiguquli se-catalytic semoto sisebenza, akufanele uvule "ubuchopho" ku-Euro-2 futhi ukuze ukhiphe inzwa ye-oxygen (yesibili). Lokhu kuzothinta kabi isimo senjini kanye nemingcele yayo. Yenza izinqumo ezicatshangelwe kahle nezilinganiselayo kuphela ngaphambi kokuba unqume ngoshintsho olukhulu emotweni, okuhlanganisa nesistimu yokukhipha umoya.

Ukulungiswa kwe-Lambda ku-Priore: ukuthi ungayilungisa kanjani kanye nezici zokuhlanza okufanele

Akunangqondo ukulungisa inzwa ye-oxygen uma isivele isebenze amakhilomitha angaphezu kwezinkulungwane eziyi-100. Imikhiqizo ayivamile ukuhlangabezana nalezi zinsuku zokugcina, futhi izinkinga nazo zivame ukwenzeka lapho kugijima izinkulungwane ezingu-50 km. Uma umkhiqizo ungasebenzi kahle ngenxa yokungaphenduli kahle, ungazama ukuwulungisa. Inqubo yokulungisa ihilela ukuhlanza indawo engaphezulu kusuka ku-soot. Kodwa-ke, akulula kakhulu ukususa i-carbon deposits, futhi akunakwenzeka ukwenza umsebenzi onjalo ngebhulashi lensimbi. Isizathu salokhu ukuklama komkhiqizo, ngoba indawo yangaphandle iqukethe i-platinum yokugqoka. Umthelela wemishini uzosho ukususwa kwawo.

Iqhinga elilula lingasetshenziswa ukuhlanza i-lambda. Ukuze wenze lokhu, uzodinga i-orthophosphoric acid, lapho inzwa kufanele ibekwe khona. Isikhathi sokuhlala esinconyiwe somkhiqizo nge-asidi imizuzu engama-20-30. Ukuze uthole imiphumela ehamba phambili, susa ingxenye engaphandle yenzwa. Lokhu kwenziwa kangcono ku-lathe. Ngemuva kokuhlanza i-asidi, idivayisi kufanele yomiswe. Ikhava ibuyiswa ngokuyishisela nge-argon welding. Ukuze ungasusi isikrini sokuzivikela, ungenza izimbobo ezincane kuwo futhi uzihlanze.

Lapho ubuyisela ingxenye endaweni yayo, ungakhohlwa ukuphatha ingxenye enentambo nge-graphite grease, okuzoyivimbela ukuthi inganamatheli endlini ye-catalyst (i-exhaust manifold).

Ingabe kufanelekile ukubeka iqhinga esikhundleni se-lambda ku-Priora: sembula zonke izimfihlo zokusebenzisa amaqhinga

Kufanele kuqashelwe ngaso leso sikhathi ukuthi ukungasebenzi kahle kwe-lambda probe kuyisithako esikhethekile lapho inzwa ifakwe khona. Lokhu kuyadingeka ukuze uma kwenzeka ukwehluleka kwe-catalyst (noma ukungabi khona kwayo), inzwa ye-oxygen yokuxilonga idlulisela ukufundwa okudingekayo ku-ECU. Ukubeka i-snag esikhundleni sokulawula i-lambda akukhuthazwa, njengoba kulokhu injini ngeke isebenze kahle. I-spacer ibekwe kuphela futhi kuphela uma kwenzeka ikhompuyutha idukisa mayelana nesimo sangempela sezindaba ohlelweni lwe-exhaust.

Akunconywa ukusebenzisa imoto nge-converter catalytic enesici, njengoba lokhu kuzoholela kwezinye izinkinga. Yingakho amaqhinga evame ukufakwa ku-CC yesibili ukuze abonise i-ECU ukuthi i-catalyst isebenza kahle ngokomqondo (empeleni, ingase ibe nephutha noma ilahlekile). Kulokhu, awudingi ukushintsha i-firmware ku-Euro-2. Kubalulekile futhi ukuqonda ukuthi i-firmware ayilungisi inkinga uma inzwa ye-oxygen inesici. Le divayisi kufanele isebenze kahle, futhi kulokhu kuphela injini izosebenza kahle.

Kuyinto encane kakhulu yokuphazamiseka kune-converter entsha ye-catalytic noma i-firmware ye-ECU. Inqubo yokufaka ayithathi ngaphezu kwemizuzu eyi-15.

Sengiphetha, kudingekile ukufingqa futhi ubonise iqiniso lokuthi abanikazi bezimoto abaningi babheka i-lambda probe njengento engasho lutho emotweni futhi ngokuvamile bavele basuswe kanye nabaguquli be-catalytic, izicabucabu ezingu-4-2-1 nezinye izinhlobo zokufaka. Nokho, le ndlela ayilungile ngempela. Ngemuva kwalokho, kunezikhalazo mayelana nokusetshenziswa okuphezulu, amandla aphansi kanye nokusebenza okungazinzile kwenjini yomlilo yangaphakathi. Lokhu kucasuka okuncane (ekuqaleni, ubuso obungaqondakali) kuyimbangela yazo yonke into. Kubalulekile ukusondela ngokuzibophezela ekulungiseni imoto yakho, ngoba noma yikuphi ukuguqulwa akuhlanganisi nje kuphela ukonakala kokusebenza kwayo, kodwa futhi nasekunciphiseni ukuphila kwayo kwenkonzo.
