Dareemaha ogsijiinta ee baabuurta.
Dareemka oksijiinta baabuurta waa dareenka jawaab celinta muhiimka ah ee nidaamka xakamaynta mishiinka EFI, waana qaybta ugu muhiimsan ee lagu xakameynayo qiiqa qiiqa baabuurta, la yareeyo wasakhowga deegaanka baabuurta iyo wanaajinta tayada gubista shidaalka ee mishiinka baabuurta.
Waxaa jira laba nooc oo ah dareemayaasha oksijiinta, zirconia iyo titanium dioxide.
Dareemka oksijiinta waa isticmaalka walxaha xasaasiga ah ee dhoobada si loo cabbiro awoodda oksijiinta ee foornooyinka kuleylka ee kala duwan ama tuubooyinka qiiqa, xisaabinta fiirsashada oksijiinta ee u dhiganta mabda'a dheelitirka kiimikada, si loo kormeero loona xakameeyo saamiga hawada iyo shidaalka gubanaya ee foornada, si loo hubiyo tayada wax soo saarka iyo heerarka qiiqa qiiqa ee walxaha cabbiraadda, oo si ballaaran loogu isticmaalo dhammaan noocyada gubasho dhuxusha, gubashada saliidda, gubashada gaaska iyo xakamaynta jawiga foornada.
Dareemka oksijiinta waxaa loo isticmaalaa in si elektaroonik ah loo xakameeyo nidaamka xakamaynta jawaab celinta ee qalabka lagu duro shidaalka si loo ogaado feejignaanta oksijiinta ee gaaska qiiqa iyo cufnaanta saamiga hawada iyo shidaalka, si loo kormeero saamiga hawada-fuelka ee aragtida (14.7: 1) gubasho Matoorka dhexdiisa, iyo in loo diro calaamadaha jawaab celinta kombayutarka.
Mabda'a shaqada
Dareemka ogsijiinta wuxuu u shaqeeyaa si la mid ah batteriga, iyadoo curiyaha zirconia ee dareemayaasha uu u dhaqmo sida elektrolytka. Mabda'a shaqada aasaasiga ah waa: xaaladaha qaarkood (heerkulka sare iyo platinum catalysis), farqiga u fiirsashada oksijiinta u dhexeeya gudaha iyo dibadda ee Hao oxide waxaa loo isticmaalaa si ay u abuuraan kala duwanaansho iman kara, iyo weyn farqiga u fiirsashada, weyn yahay farqiga u iman kara . Waxa ku jira Ogsajiinta ku jirta hawadu waa 21%, gaasta qiiqa ka dib marka la shido oo la ururiyo runtii kuma jiraan ogsijiin, gaaska qiiqa ka baxa ka dib marka la gubo isku dar ah ama gaaska qiiqa ka dhasha dab la'aanta ayaa ka kooban oxygen badan, laakiin weli aad bay uga yar tahay ogsijiinta hawada ku jirta.
Iyada oo hoos timaad heerkulka sare iyo platinum, oksijiinta ku xiran dareeraha oksijiinta ayaa la wada baabbi'iyaa, markaa farqiga korantada ayaa la soo saarayaa, korantada wax soo saarka ee isku-darka isku-dhafka ah waxay ku dhowdahay 1V, isku-darka isku-darka ah wuxuu ku dhow yahay 0V. Marka loo eego calaamadda danab ee dareeraha oksijiinta, saamiga hawada iyo shidaalka ayaa la kantaroolaa si loo hagaajiyo ballaca garaaca duritaanka shidaalka, sidaas darteed kontoroolka elektaroonigga ah ee dareemayaasha oksijiinta ayaa ah dareenka muhiimka ah ee cabbiraadda shidaalka. Dareemka ogsijiinta waxa kaliya oo si buuxda loogu tilmaami karaa heerkul sare (dhammaadka waxa uu gaadhaa in ka badan 300 ° C) waxana uu soo saari karaa danab. Waxay si degdeg ah uga jawaabtaa isbeddellada isku dhafka ah ee ku saabsan 800 ° C.
Talooyin
Dareemka oksijiinta ee zirconium dioxide ayaa ka tarjumaysa isbeddelka xoojinta isku dhafka gubanaya iyada oo loo marayo isbeddelka korantada, iyo dareemaha oksijiinta titanium dioxide ayaa ka tarjumaysa isbeddelka isku dhafka gubanaya iyada oo loo marayo isbeddelka caabbinta. Nidaamka xakamaynta elektaroonigga ah ee isticmaalaya dareeraha oksijiinta ee zirconia ma xakamayn karo saamiga dhabta ah ee hawada iyo shidaalka ee u dhow saamiga hawada-fueld ee aragtida marka xaaladda shaqada matoorka ay sii xumaato, halka dareenka oksijiinta titanium dioxide uu sidoo kale xakameyn karo saamiga dhabta ah ee hawada iyo shidaalka ee u dhow aragtida aragtida. saamiga hawada iyo shidaalka marka matoorku xaalada shaqada ay ka sii darto.
Mugga cirbadeynta (ballaadhka garaaca garaaca) ee lagu hagaajiyo unugga kantaroolka wakhti gaaban sida ku cad calaamadda dareemayaasha oksijiinta waxaa loo yaqaannaa hagaajinta shidaalka muddada-gaaban, kaas oo lagu xakameynayo koronta soo-saarka dareeraha oksijiinta.
Sixitaanka shidaalka ee muddada-dheer waa qiimaha lagu go'aamiyo wax ka beddelka unugga kantaroolka ee qaab-dhismeedka xogta hawlgalka ee unugga iyada oo loo eegayo isbeddelka isku xidhka sixitaanka shidaalka muddada-gaaban.
Cilada guud
Marka shidma oxygen ku guuldareysto, kombiyuutarka ee nidaamka duridda shidaalka elektarooniga ah ma heli karaan macluumaadka of fiirsashada oxygen ee tuubada qiiqa, si aanay jawaab celin kartaa xakamaynta saamiga hawada-shidaalka, taas oo kordhin doonta isticmaalka shidaalka engine iyo wasakhowga qiiqa, Matoorku waxa uu u muuqan doonaa xaw-la'aan aan degganayn, dab la'aan, kor u kac iyo ifafaale kale oo cillad ah. Sidaa darteed, khaladka waa in meesha laga saaraa ama la beddelaa waqti ku habboon [1].
Khaladka sunta
Sumaynta dareemayaasha oksijiinta waa mid soo noqnoqda oo ay adagtahay in laga hortago guuldarada, gaar ahaan isticmaalka joogtada ah ee baabuurta shidaalka rasaasta ah, xitaa dareeraha cusub ee ogsajiinta, wuxuu shaqeyn karaa oo keliya dhowr kun oo kilomitir. Haddii ay tahay sunta rasaasta yar oo keliya, ka dib isticmaalka taangiga gaaska aan sunta rasaasta lahayn waxay baabi'in kartaa sunta rasaasta dusha sare ee dareeraha ogsijiinta oo dib ugu soo celisa hawlgalka caadiga ah. Si kastaba ha ahaatee, inta badan sababtoo ah heerkulka sare ee qiiqa, sunta rasaasta ayaa gudaha u soo gala, taas oo caqabad ku ah faafinta ions oksijiinta, taas oo ka dhigaysa dareenka ogsijiinta mid aan waxtar lahayn, wakhtigaas oo kaliya ayaa la bedeli karaa.
Intaa waxaa dheer, sunta silikon ee dareemayaasha oksijiinta sidoo kale waa dhacdo caadi ah. Guud ahaan, silica-ku-abuuray ka dib markii la gubo xeryahooda Silicon ee ku jira shidaalka iyo saliidda saliidda, iyo gaaska silikoon ee ka soo baxa isticmaalka aan habooneyn ee gaasaska caagga ah ee silikoon ayaa ka dhigi doona dareeraha oksijiinta oo guuldareysta, markaa tayada tayada wanaagsan iyo saliidda saliidda waa in la isticmaalo. .
Marka la dayactirayo, waxaa lagama maarmaan ah in si sax ah loo doorto oo loo rakibo gaasaska caagga ah, ha codsan dareerayaasha iyo wakiilada anti-stick aan ahayn kuwa lagu qeexay soo saaraha ee dareemayaasha, iwm. Dareemaha oksijiinta, ama saliidda ama boodhka iyo sediments kale ayaa la galaa gudaha dareeraha oksijiinta, taas oo xannibi doonta ama xannibi doonta hawada dibadda gudaha gudaha dareeraha oksijiinta, si ay calaamadda wax-soo-saarka dareeraha oksijiinta u noqoto mid toos ah. ECU ma sixi karto saamiga hawada iyo shidaalka wakhtiga. Soo saarista kaydka kaarboonka ayaa inta badan lagu muujiyaa korodhka isticmaalka shidaalka iyo korodhka xoogga leh ee qiiqa sii daaya. Waqtigaan, haddii wasakhda laga saaro, waxay ku soo noqon doontaa shaqada caadiga ah.
Dildilaaca dhoobada
dhoobada dareeraha ogsijiinta waa mid adag oo jajaban, oo ku garaaca walxo adag ama ku afuufo qulqulka hawada xooggan waxay ka dhigi kartaa inay burburto oo fashilanto. Sidaa darteed, waxaa lagama maarmaan ah in si gaar ah loo taxaddaro marka la xalinayo dhibaatooyinka oo lagu beddelo waqtiga.
Siliggii baloogga ahaa waa gubtay
Siliggii iska caabinta kuleyliyaha ayaa gubtay. Dareemka ogsijiinta kuleyliyaha ah, haddii siliga iska caabbinta kuleyliyaha uu gubto, way adagtahay in dareemuhu gaaro heerkulka shaqada caadiga ah oo uu lumiyo shaqadiisa.
Khadka goynta
Wareegga gudaha ee dareeraha ogsijiinta waa go'an yahay.
Habka kormeerka
Hubinta iska caabinta kulaylka
Ka saar furka suunka dareemayaasha oksijiinta, oo isticmaal multimeter si aad u cabbirto iska caabbinta u dhexeysa tirka kuleyliyaha iyo tiirka birta ee ku jira terminalka dareemayaasha oksijiinta. Qiimaha iska caabintu waa 4-40Ω (tixraac tilmaamaha tusaalaha gaarka ah). Haddii aysan la kulmin heerka, beddel dareenka ogsijiinta.
Cabbirka danab-celinta
Marka la cabbirayo danab-celinta ee dareeraha ogsijiinta, fur suunka ee dareeraha ogsijiinta waa in la furo, iyo silig dhuuban waa in laga soo qaadaa terminalka wax soo saarka ee danab jawaab-celinta dareeraha oksijiinta sida ku cad jaantuska wareegga ee moodeelka, iyo dabadeed ku xidh xidhidhiyaha suunka. Korontada jawaab celinta waxaa laga cabbiri karaa xariiqda rasaasta inta lagu jiro hawlgalka injiinka ( moodooyinka qaarkood ayaa sidoo kale cabbiri kara danabka jawaab celinta dareeraha ogsijiinta ee godka ogaanshaha cilladda). Tusaale ahaan, baabuur taxane ah oo ay soo saartay shirkadda Toyota Motor Company waxay si toos ah uga cabbiri kartaa danab-celinta dareeraha ogsijiinta ee OX1 ama OX2 ee godka ogaanshaha cilladda).
Marka la cabbirayo tamarta jawaab celinta dareeraha oksijiinta, waxa ugu wanaagsan in la isticmaalo multimeter nooca tilmaame oo leh kala duwanaansho hooseeya (badanaa 2V) iyo cidhiidhi sare (iska caabin gudaha ah oo ka weyn 10MΩ). Hababka ogaanshaha gaarka ah waa sida soo socota:
1. U rog matoorka kulayl heerkul caadi ah (ama ku wad 2500r/min ka dib markaad bilowdo 2min);
2. Ku xidh qalinka taban ee joogsiga danabka multimeter E1 ama electrode-ka taban ee batteriga ku jira godka cilada lagu ogaanayo, iyo qalinka togan ku xidh xidhka OX1 ama OX2 ee godka cilada lagu ogaado, ama lambarka oo ku yaal furka xadhkaha fiilooyinka ee dareeraha ogsijiinta.
3, u ogolow in mishiinku ku socdo xawaare dhan 2500r/daqiiqo, oo hubi in tusaha voltmeter-ku uu hore iyo gadaal u luli karo inta u dhaxaysa 0-1V, oo diwaangeli tirada voltmeter-ka lulaya 10s gudahood. Xaaladaha caadiga ah, horumarka xakamaynta jawaab-celinta, danab-celinta dareen-celinta oksijiinta ayaa si joogto ah u beddeli doonta kor iyo hoos 0.45V, iyo danab-celinta jawaab-celinta waa in ay beddeshaa wax aan ka yarayn 8 jeer 10s gudahood.
Haddii ay ka yar tahay 8 jeer, waxay la macno tahay in dareemayaasha oksijiinta ama nidaamka xakamaynta jawaab celinta uusan si sax ah u shaqeynin, taas oo laga yaabo inay keento kaarboon ururinta dusha sare ee dareeraha oksijiinta, si dareenka hoos u dhaco. Si taas loo gaaro, mishiinka waa in lagu ordaa 2500r/min ilaa 2 daqiiqo si meesha looga saaro kaydka kaarboon ee dusha sare ee dareeraha ogsijiinta, ka dibna hubi danab-celinta. Haddii tilmaamayaasha voltmeter-ka uu weli si tartiib tartiib ah isu beddelayo ka dib marka kaarboonka la saaro, waxay muujinaysaa in dareemayaasha ogsijiinta uu dhaawacmay, ama wareegga kontoroolka jawaab celinta kombuyuutarku waa khalad.
4, ogsijiin dareenka muuqaalka muuqaalka midabka
Ka saar dareeraha ogsijiinta tuubada qiiqa oo hubi in daloolka hawo-mareenka ee hoyga dareemayaasha uu xanniban yahay iyo in xudunta dhoobada ay dhaawacday. Haddii ay waxyeello gaarto, beddel dareenka ogsijiinta.
Cilladaha waxaa sidoo kale lagu go'aamin karaa iyadoo la eegayo midabka qaybta sare ee dareenka ogsijiinta:
1, dusha sare ee cawlan: kani waa midabka caadiga ah ee dareeraha ogsijiinta;
2, korka cad: oo ay keento wasakhowga silikoon, dareeraha oksijiinta waa in la beddelaa wakhtigan;
3, dusha sare ee brown (sida ku cad sawirka 1): ay keento wasakhowga rasaasta, haddii ay halis tahay, waa in sidoo kale la beddelaa dareeraha ogsijiinta;
(4) Dusha sare ee madow: oo ay keento kaydinta kaarboonka, ka dib marka la tirtiro khaladka kaydinta kaarboon ee mishiinka, kaydinta kaarboon ee dareeraha ogsijiinta guud ahaan si toos ah ayaa loo saari karaa.
