Lambda Inzwa: Izindlela ( "Priora", "Octavia", "Renault Megane 2," "Ford Focus 2")

Kulesi sihloko uzofunda ngalokho enze uphenyo lambda, izibonakaliso ukwehluleka node, cabangela futhi. Ibizwa nangokuthi i-oksijini inzwa. It efakwe kule ipheshana qeda we omlilo yangaphakathi injini yezimoto. Ngaphezu kwalokho, inzwa ibekwe kokubili kaphethiloli kanye izinjini udizili.

ulwazi oluyisisekelo mayelana inzwa umoya-mpilo

Lambda probe akufane Umgomo we operation, ngoba eyeseli electrochemical ehlanganisa electrolyte okuqinile Ceramic esekelwe zirconia. Futhi kusetshenziswa zobumba alloying yttria. Sishaye phezulu kuyinto ungqimba elincanyana nge ukusetshenziswa ne-platinum. It kuvela ukuthi umuntu electrode uthola qeda gas, ngenkathi ezinye - emoyeni emkhathini. Kuyinto ngokusebenzisa lesi siqhathaniso kwenzeka igesi imingcele wasebenza emoyeni evamile ozungeze umhlaba wethu. Futhi uzinake ukuthi ukusebenza kahle kunazo zonke yenziwa ngesikhathi eshisa ngaphezu kuka-degree angu-300. Kungaphansi enjalo Ukushisa electrolyte ka zirconium iqala ekhaya azokuqhubela zamanje. Futhi manje sekuyisikhathi ukufunda ngalokho Kuthinta indlela probe lambda. Izimpawu "Priora", isibonelo, ziyonquma, ngisho ngesikhathi secala.

Isimiso ezisebenza we probe lambda

Ngenxa yokuthi kukhona umehluko okuqukethwe mass umoya-mpilo, lo voltage okukhiphayo livela ezweni electrode we inzwa. Ukuze kwandiswe ukuzwela zedivayisi ezingeni lokushisa ongaphakeme, isibonelo ngesikhathi injini isiqalo, kubalulekile ukusebenzisa Ukushisa bephoqeleka. ikhoyili Electric Itholakala Ceramic umzimba lambda uphenyo. It has a uxhumano imoto isimiso sikagesi. Kukhona umoya-mpilo inzwa isici, ogxile titanium dioxide. Ushintsha ukumelana yabo lapho injini isebenza. Kuyinto kule isimiso usebenza lambda uphenyo. Izimpawu iVolkswagen Golf 3 ziyefana ngezimoto yasekhaya.

Oxygen inzwa Jobe

Ngalesi sikhathi, uma kukhona qala-up kanye iyazifudumeza injini, injini esebenza ngaphandle idatha ivela probe lambda. Lonke emoyeni-fuel isilinganiso ukulungiswa kwenzeka kwi idatha etholwe kusuka kwamanye amadivayisi. Kahle kahle, lokhu isikhundla izinzwa umphini ngejubane mpintsha, injini lokushisa, injini. Isici esiyinhloko probe lambda esekelwe zirconium - wukuthi nge ukuphambuka kancane kusukela uthola umoya-mpilo okuqukethwe ukuhlaziywa of the ukwakheka ingxube fuel kwenzeka ushintsho oluphawulekayo endleleni okukhipha voltage in uhla 0.1-0.9 volts.

Titanium-mpilo izinzwa

Kukhona futhi izinzwa wenza ama-titanium dioxide. Khona-ke, uma kukhona ushintsho ingxenyenamba mass oxygen amagesi qeda, kancane kancane ukushintsha emqulwini ukumelana. voltage ekhiqizwa kuleli izinzwa lokhu design ingekho. Ziyakwazi ebudisi khulu ukwedlula zirconium, wasebenzisa izimoto ezibizayo kakhulu ezifana BMW, Nissan, "Jaguar". On isabelomali imoto kumadivayisi esekelwe titanium, ngokuvamile esetshenziselwa ngenxa yezindleko yabo ephakeme. On izimoto medium and ongaphakeme-ebangeni zirconia eshibhile-mpilo inzwa esetshenziswa. Izimpawu "Renault Megane 2" libonisa lezo musa ihluke labo abakhona izimoto yasekhaya.

Umehluko lambda iphenya

Kufanele kuqashelwe ukuthi imigomo yomsebenzi phezu izinzwa-mpilo ziyafana, akuxhomekile ubani umenzi. Umahluko owokuthi okuyinto usayizi iphakethe salezi zici. Kungase kube nezinye uxhumano abanye, ngokuvamile kukhona umehluko isixhumi. Zonke izinzwa, njengoba kushiwo ngenhla, abangewona evuthayo noma cha. Ngenxa yalokho, bayehluka kunombolo izintambo ukuxhuma. Ngokusho izinto umehluko yilezi ezilandelayo: noma zirconium noma titanium. Ekuphetheni kwakamuva kwe-heater njalo has umbala obomvu. Kukhona futhi izinhlobo diesel. Ziyakwazi broadband ngaphezulu. Awukwazi ukufaka injini uphethiloli probe lambda. Izimpawu ( "Skoda Octavia" kuyasithakazelisa abashayeli abaningi) ahambisana ukuhoxiswa ngekhodi yephutha nencazelo emfushane.

Kungani ehluleka lambda Uphenyo

njalo yona kanye imbangela yokwehluleka nisebancane abampofu izinga uphethiloli. ngokushesha Iron nomthofu, okungase khona uphethiloli abampofu clog-platinum electrode. Ngenxa yalokho, ukwehluleka inzwa oksijini, ngeke asuse kahle bonke ubufakazi. Uma izindandatho bushelelezi abe ukukhiqizwa eqinile, igemfe qeda uzothola ethile uwoyela. Kuba yisikhathi futhi lapho imbangela ukwehluleka kwanoma inzwa umoya-mpilo. Ngisho noma zonke engozini okungazelelwe inzwa-mpilo eseke kancane kuphela noma yokuwasha, ungasho ngokushesha ukuthi lezi zindaba. Akenzi ukuzwa kokuthola lezi zixazululo. Ukubhujiswa probe lambda kwenzeka icala lapho ohlelweni qeda zenzeka kwetandla lenyenti. Ceramics zintekenteke kakhulu, ngakho ukuba amagalelo abukhali enjalo kwakungatholakala kubuqede. Lapho ukufakwa engafanele engela ukuthungela noma i ocebile ngokweqile umoya fuel uqweqwe Ukushisa enamandla inzwa izindlu. Lokhu kubangela ukwehluleka kwesikhathi.

izizathu Ngaphansi ethandwa ngokwehluleka

Sicela uqaphele ukuthi uma ufaka uphenyo lambda ingasetshenziswa hhayi ezihlukahlukene sealants, okuncike silicon. Ungase futhi abhubhise inzwa oksijini, uma isikhathi esiningi ukuzama ukuqala injini, okwenza kokuhlaba ikhefu elincane phakathi ngamunye mzamo. Kuncike ekutheni injini ngeke ukuqala. Lokhu kuzokwenza nakanjani kuyoholela yokuthi ingxube uphethiloli emoyeni bayokwakha ohlelweni qeda. Ngemva kwesikhashana uzovutha bese udala ibhomu elinamandla. Ngisho contact engaphelele noma short circuit yesifunda okukhipha, singayibhubhisa kudivayisi. izakhi isisetshenziswa Wabelane luyehluka in the ububanzi ayizinkulungwane 30..70 amakhilomitha. It ixhomeke izimo ukuxhashazwa kuthatha ngaphansi kwazo endaweni. Isikhathi sempilo enkulu e izinzwa lapho kukhona Ukushisa ezengeziwe. Ngo iningi izimoto sisetshenziswa uphenyo design lambda ezinjalo. Izimpawu ( "Ford Focus 2" noma "Skoda" utholakale yakho) bayafana. Ngakho-ke, ungakwazi ukuxilonga kanye ngokuzimela uma ukuqaphela kahle zonke izimpawu.

Njalo zokugwema ukuphuka inzwa

Phakathi ukwehluleka ethandwa kakhulu kungenziwa kuphawulwe eziphukile Ukushisa isici, futhi ukulahlekelwa ukuzwa. Ngenxa isivinini yakamuva liyancipha kudivayisi. Into ebaluleke kakhulu - zama ukungazivezi esikhundleni probe lambda yinoma yimuphi ngabalingisi. I electronic control unit Ngeke Laqonda isignali ongaziwa. Ngakho-ke, ukulungiswa ingxube fuel yi Simulator ngeke kwenzeke. Qaphela ukuthi uma inzwa-mpilo isebenza ngempumelelo ezweni lakithi (eliphansi uphethiloli), nokuphila kwaso kwakusobala ukuthi kuphele iminyaka engaphezu kwemithathu, awukwazi ngisho ukufinyelela diagnostician. Vele kudingeka esikhundleni inzwa umoya-mpilo. Izimpawu "Skoda" libonisa ngokucacile lapho akhwela ayizinkulungwane 70. Km. Ezinye modeli umoya-mpilo izinzwa nabo bonke abe nokuphila kancane angaphezu kuka-30 eziyinkulungwane amakhilomitha.

Indlela yokubona inzwa okuyiphutha

Uma kukhona operation engazinzile yenjini ngesivinini aphansi, kuba sengathi injini "troit." Futhi kwandisa ukusetshenziswa uphethiloli, imoto Dynamics siba sibi. Ngokuvamile wezwa yequbula, wafting kusukela ekwandeni ngemuva kokuthi uvale injini. Kungenzeka futhi ukwandisa (abalulekile) lokushisa kulethe. Ngezinye izikhathi kuyenzeka Ukushisa esinjalo, metal ukufuthelana nje. Kwezinye izimoto, iphutha kungabuye yahlulelwe isibani isixwayiso Hlola Engine. Kodwa, ngeshwa, akuzona zonke uhlelo electronic control sikwazi ukubona futhi ukhombise iphutha lento.
