Lambda woluvo: uphawu ( "Priora", "octavia", "Renault Megane 2," "Ford Focus 2")

Kweli nqaku uza kufunda ngento uphenyo Lambda, imiqondiso ukusilela node, cinga nayo. Libizwa ngokuba isivamvo oksijini. It is ukufakwa qeda kwisiqwenga ukutshiswa lwangaphakathi injini ngomatshini. Ngaphezu koko, lo woluvo ibekwe kokubini ipetroli engines diesel.

ulwazi olusisiseko malunga woluvo oxygen

Lambda probe yinto efanayo siseko ukusebenza, kuba iseli electrochemical kuqulethe electrolyte yodongwe eqinileyo esekelwe zirconia. Kwakhona yakho usebenzisa ngodongwe alloying yttria. Ukutshiza Phezulu umaleko obhityileyo kunye nokusetyenziswa platinum. Kubonakala ukuba omnye electrode ufumana igesi zeemoto, lo gama enye - umoya evela emoyeni. Kungenxa uthelekiso kwenzeka parameters negesi wasebenza kunye nomoya oluqhelekileyo esesibhakabhakeni. Kananjalo kubalulekile ukuba siqaphele ukuba ukusebenza kakhulu kakuhle yenziwa kwiqondo lobushushu ngentla degrees 300. Kuyinto phantsi loo zokufudumeza electrolyte of zirconium uqalisa ukuqhuba yangoku. Kwaye ngoku lixesha lokuba bafunde oko iphembelela indlela probe Lambda. Iimpawu "Priora", umzekelo, uya kumisela, nakule mimandla kwetyala.

Umgaqo esebenza ngayo probe Lambda

Ngenxa yokuba kukho umahluko kokuqulathwe ubunzima ioksijini, le ombane yemveliso evela phesheya i electrode wexesha elongezelelweyo lomenzi woluvo. Ukwandisa uvakalelo kwefowuni kubushushu obuphantsi, umzekelo ngexesha injini ekuqaleni, kuyimfuneko ukusebenzisa ukufudumeza unyanzelekile. coil Electric ibekwe kwi yodongwe Lambda umzimba probe. Kuye uqhagamshelwano inkqubo yombane isithuthi. Kukho umoya sensor element, olusekelwe titanium dioxide. Yena uyawaguqula besenza xa injini uyasebenza. Kungenxa kule mgaqo usebenza Lambda probe. Iimpawu VW Golf 3 ziyafana ngeemoto zasekhaya.

isivamvo Oxygen Job

Ngalo mzuzu, xa kukho ukuqala-up, esotha i-injini, injini isebenza ngaphandle data evela probe Lambda. Ukulungiswa ratio air-fuel yonke lwenzeka kwi data zifumaneka kwezinye izixhobo. Ingakumbi, le sikhundla abenzi valve kwi isantya umcephe wokunyusa, ubushushu benjini, injini. Eyona iphambili phenyo Lambda ngokusekelwe zirconium - kukuba kunye unxaxho kancinane kwisiqhelo kucazululo kwikhontenti ye-oksijini nokwakhiwa umxube kwamafutha kwenzeka utshintsho ebalulekileyo ombane abagqibayo kuluhlu 0.1-0.9 volts.

abenzi Titanium oxygen

Kukho kwakhona abenzi boluvo ezenziwe titanium dioxide. Ngoko, xa kukho utshintsho iqhezu ubunzima oksijini iigesi zeemoto, baza ngokuthe ngcembe ukutshintsha resistance umthamo. ombane eyenziwe nabenzi boluvo yalo kuyilo lungenzeki. Ifana ezintsonkothileyo ngaphezu zirconium, ezisetyenziswa iimoto imali eninzi kakhulu ezifana BMW, Nissan, "Jaguar". Kwizixhobo imoto mali olusekelwe titanium, adla kusetyenziswa ngenxa yeendleko yazo ngaphezulu. Ezimotweni of aphakathi ezisezantsi-grade zirconia enganeno isivamvo oxygen kusetyenziswa. Iimpawu "Renault Megane 2" ubonisa abo musa kwahluka kwabo babekho ezimotweni zasekhaya.

Ukungaboni ixhokonxa Lambda

Kufuneka kuqatshelwe ukuba imigaqo umsebenzi nabenzi boluvo ioksijini ayafana, akuxhomekekanga ngubani na umenzi. Umahluko kuphela kukuba apho isayizi package ezi zinto. Kusenokwenzeka ukuba ezinye connection, abantu basoloko umahluko isinxibelelanisi. Bonke abenzi boluvo, njengoko kukhankanyiwe ngasentla, ebushushwini babo okanye hayi. Ngenxa yoko, abafani kwenani ngcingo ukudibanisa. Ngokutsho izinto umahluko ngala alandelayo: nokuba zirconium okanye titanium. Elokuphetha zakutshanje imbawula usoloko umbala obomvu. Kukho iintlobo iinjini diesel. Yokuba broadband ngakumbi. Awunako ukufaka phezu injini ipetroli uphenyo Lambda. Iimpawu ( "Skoda octavia" Kwakhona umdla abaqhubi ezininzi) zihamba ekurhoxisweni i ikhowudi isiphoso inkcazelo emfutshane.

Kutheni ehluleka Lambda probe

qho kakhulu unobangela ukusilela ngaphambi ihlwempu umgangatho ipetroli. Nesinyithi nelothe, ezinokuba khona ipetroli kakuhle ngoko nangoko ucingo electrode platinum. Ngenxa yoko, ekungaphumelelini woluvo ioksijini, kodwa ayikwazi kakuhle ukususa bonke ubungqina. Ukuba amakhonkco ize unayo imveliso nkqi na, umbhobho zeemoto zethu ziya kufumana isixa esithile zeoli. Kananjalo ngunobangela yokusilela ngaphambi woluvo ioksijini. Nokuba bonke ingozi ngequbuliso kule woluvo oxygen ezikhuphile isuntswana kuphela okanye isepha, ungenza ngokukhawuleza xelela ukuba waqhekeza. Yena akayi kubona ufumane ezi izisombululo. Ukutshatyalaliswa uphenyo Lambda kwenzeka kwimeko apho inkqubo exhaust kwenzeka ushaya. Ukubumba zibuthathaka kakhulu, kangangokuba izithonga ezibukhali ezifana ukuba siyonakalise. Xa ufakelo ngokungafanelekanga le angle ucinezelo okanye umxube zizityebi ngokugqithiseleyo amafutha umoya zokufudumeza elinqatyisiweyo izindlu woluvo. Oku kubangela ukungaphumeleli kwexesha.

izizathu ethandwayo Ngaphantsi zokusilela

Nceda uqaphele ukuba xa ufaka uphenyo Lambda ayikwazi ingasetyenziswa ezahlukeneyo sealants, ehlanganisiweyo esusela kwi-electronic. Uyakwazi kuzitshabalalisa woluvo ioksijini, ukuba ixesha elininzi ukuzama ukuqalisa injini, ukwenza kokunqumama encinane phakathi umzamo ngamnye. Ngaphandle kokuba injini akayi ukuqala. Oku nakanjani kukhokelela ekubeni umxube amafutha-moya uya kwakha kwinkqubo zeemoto. Emva komzuzwana litshise ukudala udubulo enamandla. Nkqu contact ezineziphene okanye isiphaluka elifutshane kwisekethe imveliso, unako ukutshabalalisa ifowuni. izinto lwemvelaphi eyahlulwayo kuyahlukana kuluhlu 30..70 ophosa. It ixhomeke kwiimeko phantsi apho ukusetyenziswa kwenzeka. Ixesha inkulu abenzi boluvo apho kukho ukufudumeza olongezelelweyo. Kuninzi zimoto lisetyenziswa esinjalo probe design Lambda. Iimpawu ( "Ford Focus 2" okanye "Skoda" ezifumaneka ilifa lakho) ayafana. Ngoko ke, uyakwazi ukubona yaye ngokuzimeleyo ukuba bayazi kakuhle zonke iimpawu.

isivamvo breakage rhoqo

Phakathi yokusilela kakhulu ethandwa onokubonwa isiqalelo zokufudumeza ezaphukileyo, kunye nelahleko koluvo. Ngenxa kwisantya yamvanje liyancipha idivayisi. Eyona nto ibalulekileyo - zama ukuba indawo uphenyo Lambda nawuphi na njengaye. Iyunithi yolawulo elektroniki akakwazi ukubona umqondiso engaqhelekanga. Ngoko ke, ulungiso umxube amafutha yi lo mshini akuyi kwenzeka. Qaphela ukuba ukuba eli woluvo ioksijini lisebenza ngempumelelo kwilizwe lethu (ipetroli ihlwempu-quality), kunye nobomi balo ngokucacileyo kwiminyaka emithathu, akunako ukufikelela diagnostician. Kufuneka nje endaweni woluvo oksijini. Iimpawu "Skoda" ubonisa ngokucacileyo xa aqabele 70 lamawaka. Km. Ezinye modeli zokuva ioksijini bonke ubomi kancinane ngaphezulu kwama-30 ophosa.

Indlela yokubona zincwadi Womenzi eziphosakeleyo

Ukuba kukho umsebenzi engazinzanga ye-injini ngesantya esisezantsi, kuba sengathi ukuba injini "troit." Kwaye kwandisa ukusetyenziswa zepetroli, isithuthi okuhambisa mandundu. Kudla weva lanqanqaza, elimnandi ukusuka kuvala emva kwakho vala injini. Kuyenzeka nokwandisa (ebonakalayo) lobushushu kuvala i. Maxa wambi kwenzeka zokufudumeza ezinjalo, intsimbi itshiswe nje. Kwezinye izithuthi, i fault nako kugwetywa isibane isilumkiso Khangela yenjini. Kodwa ke, ngelishwa, asingabo bonke inkqubo yolawulo yekhompyutha ukubona kwaye ubonise nandzu yale nto.
