Ungayenza kanjani i-lambda probe snag yokuzenzela
Okuqukethwe
Zonke izimoto zanamuhla zifakwe i-honeycomb exhaust gas neutralizer - i-catalyst. Ibizwa kanjalo ngesisekelo sokuphendula kwamakhemikhali okwenzeka lapho, lapho izakhi ezihloniphekile zokugcwalisa zisheshisa futhi zenze kube nokwenzeka ukucubungula izinto eziyingozi zibe ezingathathi hlangothi ngesivinini esikhulu. Kodwa ngezinye izikhathi le divayisi ewusizo ngokwayo iba umthombo wezinkinga ezinkulu.
Kungani ukhohlisa inzwa ye-oxygen
Isakhiwo esincanyana se-catalyst asimelani nokulayisha ngokweqile kwemishini nokushisa isikhathi eside. Izinga lokushisa lapha ngisho nakwimodi evamile lifinyelela amadigri ayinkulungwane.
Izinyosi ze-Ceramic ziyabhujiswa, futhi lokhu kubangela izimo eziyingozi:
- ukugcwalisa kuyancibilika, ama-sinters futhi uvimbele ukuphuma kwamahhala kwamagesi okukhipha amandla;
- ama-honeycombs amancane ahlanganiswe ne-soot neminye imikhiqizo enomphumela ofanayo;
- into eyingozi kakhulu ukuthi i-catalyst, abakhiqizi abavame ukuyibeka eduze ngangokunokwenzeka esiteshini sokuphuma kwekhanda le-block ukuze lifudumale ngokushesha ekushiseni okusebenzayo, liba umthombo wothuli lwe-ceramic kanye nemfucumfucu engena kumasilinda futhi ibhubhise izingxenye zenjini. .
Ezinjinini ezingathembeki ikakhulukazi ngenxa yalesi sisekelo, abanikazi bavame ukususa iziguquli eziyingozi ngisho nemayela eliphansi lemoto. Ngenxa yokusetshenziswa kwezinsimbi ezibalulekile ekwakhiweni, abanikazi abafuni ukufaka imikhiqizo ebizayo yokuqala noma yokulungisa.
Imiphumela ayivezwa nje kuphela ekwandeni kobuthi bokukhipha umoya. Isimo se-catalyst sihlaziywa ngokuqhubekayo yiyunithi yokulawula injini ye-elekthronikhi (ECU) kusetshenziswa amasiginali avela kuzinzwa ezimbili zomoya-mpilo (ama-lambda probes).
Enye yazo itholakala ngaphambi kwe-catalyst, injini ilawula ukwakheka kwengxube yokusebenza ngayo, kodwa eyesibili ibhekene ngokuphelele nokusebenza kahle kwe-neutralization yokukhipha.
Izinkomba ze-lambda yesibili zicwaningwa kusetshenziswa ikhompuyutha, okuhlanganisa nokuqhuba imijikelezo yokulawula ukushisa i-catalyst. Ukungabikho kwayo kuzobalwa ngokushesha, uhlelo luzongena kwimodi ephuthumayo futhi lugqamise inkomba yokulawula kudeshibhodi. Injini izolahlekelwa yizo zonke izici zayo, ukusetshenziswa kukaphethiloli nezinye izinkinga zizoqala.
Ukuze usebenze ngaphandle kwe-catalyst, ungashintsha uhlelo lweyunithi yokulawula. Isigaba semvelo semoto sizokwehla, kodwa ngaphandle kwalokho kuyoba inketho yokusebenza ngokuphelele, kungenzeka ngisho nokwandisa amandla nokunciphisa ukusetshenziswa, imvelo ayihambi lutho, kodwa ngenxa yezizathu ezihlukahlukene, akuwona wonke umuntu olungele ukuhamba. ngoba.
Abanye abantu bafuna ukukhohlisa uhlelo olujwayelekile lwe-ECU ngandlela-thile, benze ukufundwa okungalungile kokwenziwa kwenzwa ye-oxygen.
Umgomo wokusebenza kwe-snag lambda probe
Umphumela ofanayo ungatholakala ngezindlela zikagesi nezemishini.
- Esimweni sokuqala, isignali ikhiqizwa ukuthi, empeleni, inzwa ye-oxygen ayikhiqizi.
- Okwesibili, zonke izimo zenziwa ukuze inzwa inikeze ukufundwa okungalungile.
Akuwona wonke amasistimu angakhohliswa ngendlela enokwethenjelwa yilezo zindlela zakudala. Konke kunqunywa imishini yemoto ethile.
Inhlanganisela yemishini ye-catalyst yesistimu yokukhipha umoya
Indlela elula kungaba ukukhipha inzwa ye-oxygen endaweni elawulwayo ibanga elithile ngokuyifaka kumkhono wesikhala.
Isici esisebenzayo siqala ukusebenza endaweni lapho ukwakheka kwegesi kulinganiswa ngandlela thize, ubudlelwano obuqondile phakathi kwezenzo zekhompiyutha kanye nokuphendula kwenzwa kuyanyamalala, okubonwa izinhlelo ezilula njengesibonakaliso sokusebenza okuvamile. we-catalyst.
Amapulani
Isikhala siwumkhono wensimbi onemiphetho enentambo. Amapharamitha ochungechunge ahambisana nenzwa esetshenzisiwe. Ngakolunye uhlangothi, intambo ingaphakathi, umzimba we-lambda probe ifakwe kuwo, futhi ngakolunye uhlangothi, ingaphandle ukuze ibekwe ekufakeni okufakwe imicu ye-exhaust tract ngemuva kwe-catalyst.
Imbobo ibhojwa eduze kwe-eksisi yomkhono ukuze kudlule amagesi kusici esisebenzayo. Imingcele ye-bushing izoba ububanzi balesi siteshi kanye nebanga lapho inzwa isuka khona kude nepayipi lokuhamba kwegesi. Amanani akhethwa ngokuhlola, idatha edingekayo itholakala kalula kumamodeli athile enjini.
Ama-spacer athuthuke kakhulu afakwe izinto ezikhuthazayo. Kulesi simo, ukugeleza okuyinhloko kuya ngqo ku-outlet, futhi inzwa ye-oxygen ithola amagesi kuphela adlule ku-microcatalyst.
Isiginali izohluka kwejwayelekile, kepha amasistimu amaningi ayamukela njengokusebenza okuvamile. Ngaphandle kwalezo zimo lapho i-ECU ifuna ukufudumala i-catalyst, futhi ukufakwa ku-adaptha ngeke kusabele kulokhu nganoma iyiphi indlela. Ngaphezu kwalokho, le microcatalyst ivame ukuvaleka ngokushesha ngomsizi futhi iyeke ukusebenza ngokuphelele.
Indawo yokufaka
I-catalyst iyasuswa, futhi i-spacer ifakwe esikhundleni senzwa yesibili ye-oxygen. Ububanzi bomgodi wokusebenza bungakhethwa ngokuvumelana nokusebenza okuzinzile ngaphandle kokubonisa inkomba. Inzwa ijikijelwa ochungechungeni lwe-spacer. Umsindo we-exhaust ujwayelekile ngokufaka isivimbeli somlilo.
I-Electronic snag lambda probe
Indlela ye-elekthronikhi yokukhohlisa i-ECU inembe kakhulu. Kunezinketho eziningi lapha, kusukela kokulula, lapho isignali yenzwa ilungiswa ngesihlungi esenziwe nge-resistor kanye ne-capacitor, amanani akhethelwe ikhompuyutha ethile, nakwamanye ayinkimbinkimbi, nge i-autonomous pulse generator.
Lolu hlelo
Ukulingisa esimweni esilula kungaphansi kwesignali yokuphuma kwenzwa ye-oxygen. Kowokuqala, inezinhlangothi eziphakeme, kodwa uma zigcwaliswa ngosizo lweketango le-RC, amanye amabhlogo ngeke abone umsebenzi ongajwayelekile.
Eziyinkimbinkimbi ngokwengeziwe ziqaphela ngokushesha inkohliso emjikelezweni wokulawula wokuqala.
Uma inzwa inentambo yokushisa engalungile, khona-ke uzodinga ukufaka enye i-resistor, ngoba i-block ibona ukuphumula okunjalo ngokushesha futhi njalo.
Esikhundleni senzwa, ungaxhuma umjikelezo okhiqiza ama-pulses, afana kakhulu najwayelekile. Ngokuvamile le nketho isebenza, kodwa uma i-ECU iqeqeshelwe ukujikeleza i-catalyst, khona-ke le blende ngeke ikwazi ukuphendula ngokwanele.
Indlela yokufaka
Izingxenye zomsakazo ezidingekayo noma amabhodi afakwe phakathi kokusikwa kocingo lwesignali yenzwa ye-oxygen noma esikhundleni salo, axhumeke ngqo kusixhumi.
Imbobo yenzwa ingaxhunywa, isibonelo, ngengxenye enesici.
Iliphi iqhinga le-lambda elingcono kakhulu ongalisebenzisa
Awekho ama-cheats aphelele. Konke kuncike emotweni ethize kanye nezici zokuqaliswa komsebenzi wokuqapha isimo se-catalyst. Esimweni esivamile, ukuphela kwendlela yokuphuma ukushintsha i-firmware ye-ECU.
Ngokuvamile lokhu kuhlinzekwa ngisho nohlelo lwakhe, izimoto eziningi zikhiqizwa ezinguqulweni ezihlukahlukene, kuhlanganise nalezo ezingenawo ama-catalysts. Kunoma yikuphi, ukudlula isilawuli esakhelwe ngaphakathi ngeke kube nzima ku-chiptuner yemoto enolwazi.
Imibuzo enenani labaningi iyama futhi ibaphoqe ukuthi bahlanganyele kuzo zonke izinhlobo zamaqhinga. Lapha kuyadingeka ukuqonda ngokucacile ukuthi yiziphi izindlela ezisebenza nale moto, futhi yiziphi ezizoba ukuchitha isikhathi nemali. Noma ungazama uma ukwazi ukujika, izingxenye zomsakazo kanye nensimbi yokunamathisela.
Akunakwenzeka ukuthi ukonakalisa imoto lapha, futhi uma kwenzeka ukwehluleka kokugcina, noma kunjalo, xhumana nochwepheshe ekubhaliseni uhlelo lwekilasi eliphansi lezemvelo.
Njengenketho, ungafaka i-catalyst yokulungisa eqinile ngokwanele futhi enokwethenjelwa, okuyinto, ngokumelene nesizinda sesikhathi esichithwe kanye nokukhokhwa kwezinsizakalo zenkosi, akubukeki kubiza kakhulu.
