I-Lambda probe dummy ngezandla zakho: ukudweba

Kusuka kwinqaku uza kufunda indlela i-lambda probe eyenziwe ngayo kwaye ingaba ifanele ifakwe kwimoto yakho. Ngendlela umxube womoya ogqithisa ngayo injini, ukusebenza kwawo kuxhomekeke. Kubaluleke kakhulu ukuba ukhethe inani elifanelekileyo le-petroli kunye nomoya, kuxhomekeke kumthwalo kwi-injini.

Ukuba kwiimoto ezindala zonke iinguqulelo kumgangatho kunye nobungakanani bepetroli zixhomekeke kumatshintsho e-carburetor, kumaxesha anamhlanje ahluke ngokuthe ngqo. Zonke zinikwe ngezandla ezithembekileyo zobuchwepheshe be-microprocessor kunye nenani elikhulu leenzwa.

Isistim sejoza sisebenza njani?

Kunokwenzeka ukuhlukanisa inani lezona zinto zibaluleke kakhulu ezikhoyo kwi-injector system:

1. Itanki yeoli.
2. Inzwa yezinga le-Fuel kwikhaya elilodwa nepom kunye nesihluzo.
3. Umzila wee-oyile (efakwe kwi-injini kwigumbi elithandayo).
4. Iimbuko, ezibonelela ngokunikezelwa kwe-petroli engxube kumagumbi okutsha.
5. Iyunithi yokulawula. Njengomthetho, iphakanyiswe ngaphakathi kwimizi yemoto, ivumela ukulawula ukunikezelwa kombane womoya.
6. Inkqubo yokukhupha, eyenza ukutshabalalisa ngokupheleleyo izinto eziyingozi.

Kulokugqibela ukuba iphondo ye-lambda ikhohlisiwe. Ngezandla zakho ("Lancer 9" okanye "Lada" kuwe, akunandaba) inokwenziwa ngokulula. Kodwa kuyimfuneko kwaye uyayiqonda yonke imiphumo yokufaka "i-stub". Ukukhohlisa kwe-lambda ngezandla zaso kwi "Ngaphambi" kungenziwa kunye nokuyila okulula, nokuba kunjani na kuya kuba nempembelelo ebonakalayo kwi-injini yentsebenzo.

Zingaphi iisenjini ezisemotweni

Izixhobo zengxowan (i-lambda probes) zikhutshwe kwinkqubo yokukhupha iimoto zamanje kunye ne-injection system injection system. Kukho enye okanye ezimbini i-oxygen sensors kule nkqubo. Ukuba enye ifakwe, ifumaneka emva kokuguqula i-catalytic. Ukuba babini, ngaphambi nangemva.

Omnye ulinganisa ipesenteji ye-oksijini ngokukhawuleza ekuphumeni kwii-cylinders kwaye ithumela uphawu lwayo kwi-unit control unit. Okwesibini, ephakanyiswe emva kwe-catalyst, kuyimfuneko ukulungisa ukufundwa kokuqala.

Umgaqo wokusebenza kweprogram ye-lambda

Zonke i-electronics yeemoto, ejongene nokubunjwa ngokufanelekileyo komxube, ithatha inxaxheba ekuhanjisweni kwamafutha ngama-injection. Ukusebenzisa i-oxygen sensor, inani elifunekayo lomoya lizimisele ukwenzela ukudala umxube womgangatho. Ngenxa yokulungiswa kakuhle kweprogram ye-lambda, kunokwenzeka ukuba kufikeleleke kumgangatho ophezulu wokusingqongileyo kunye noqoqosho.

Amafutha ashushu ngokupheleleyo, kwindawo yokuphuma kombhobho, ngokufanelekileyo umoya ococekileyo ngowona yendalo. Umlinganiselo ochanekileyo womoya kunye nepetroli yinzuzo ekukhuseleni amafutha. Ngokuqinisekileyo, i- converter ye - catalytic, idibene ne-oxygen sensors, iqinisekisa ukusebenza okuzinzileyo kwenjini. Kodwa ngenxa yokuba yenziwe ngeensimbi ezixabisekileyo, iindleko zayo ziphezulu kakhulu. Yaye ukuba ithe yahluleka, ukutshintshwa kuyakuba yipenki enhle. Ngako oko, kuvela ingcamango: "Kodwa kukho iprogram ye-lambda ekhohlisayo, ngezandla zabo (i-VAZ-2107 idinga ukuba ithathe indawo ye-oxygen sensor) kuya kuba nzima ukwenza."

Iimpawu zoyilo lwe-oxygen sensor

Ukubonakala kwesi sixhobo kulula - i-electrode-housing yokuhlala, apho iifoni ziya khona. Emzimbeni, ukuthunyelwa kweplatinum (kwakuchanekileyo le nsimbi eyigugu exoxwa ngasentla). Kodwa isakhiwo sangaphakathi sisisityebi "

1. Uqhagamshelwano lwezinyithi oludibanisa iingcingo zokuxhuma kumbane osebenzayo wentloko.
2. Ukutywinwa kweedeleli ukwenzela ukhuseleko. Inomngcipheko omncinci apho umoya ungena kwi-casing.
3. I-electrode ye-Zirconium luhlobo olufihliweyo olufumaneka ngaphakathi kwinqonga le-ceramic. Xa ukuhamba kwamanzi kuphuma kule electrode, itshisa kwiqondo lokushisa kwi-300 ... 1000 degrees.
4. Ukukhusela isikhumba kunye nomngxuma wokukhupha umonakalo.

Iintlobo zeziveki

Iintlobo ezimbini ezibalulekileyo zeenjini zogesi, ezisetyenziswa njengogqirha bezithuthi:

1. Broadband.
2. Amaphuzu amabini.

Kungakhathaliseki ukuba luhlobo luni, bafumana isixhobo esingaphakathi esifanayo. Ukufana kwangaphandle, njengoko uyaziyo, kukho. Kodwa umgaqo womsebenzi uhluke kakhulu. Inzwa ye-oksijeni ye-widband yinkcazelo ephuculiweyo yamaphuzu amabini.

Inomlinganiselo wokupompa, owathi, ngenxa yokuguquka kwamandla, unikezela uphawu kwiyunithi yokulawula i-elektroniki. Kule nkalo, ukunikezelwa kwangoku kunokunyusa okanye kubuthathaka. Ngaloo xesha, ixabiso elincinci lomoya lingafika kwisithuba kwaye luhlalutyo. Kule nqanaba ukuxinwa kwe-CO kwinqwelo yokukhangela igesi kuyalinganiswa. Kodwa ngamanye amaxesha iprogram ye-lambda yenziwe kwaye ifakwe ngezandla zayo. "I-Chevrolet Lanos", umzekelo, isebenza kunye nayo kwaye inganiki iziphoso emva kokuba i-refueling enepetrolol embi.

Ukunqunywa kokungasebenzi kakuhle kwe-oxygen sensor

Ewe, le nto ayinaphakade, nangona iindleko zayo eziphezulu kunye neplatinum ekubunjweni. Kakade, iprogram ye-lambda ayikho nto kwaye ngezinye iinkalo inokumisela ubomi obude. Kwaye kuya kubakho iimpawu:

1. Umgangatho womxholo we-CO ukwandisa ngokukhawuleza kumagesi okukhupha. Ukuba imoto inesimo se-oksijeni kunye neqondo le-CO liphezulu kakhulu, oko kubonisa ukuba isixhobo sokulawula siphumelele. Qinisekisa ukuba umxholo wezinto ezinobungozi unokusebenzisa kuphela abahlalutyi begesi. Kodwa ngeenjongo zomntu siqu, akunakunceda ukuyithenga.
2. Ukwandisa ukusetyenziswa kwamanzi. Naka ingqalelo kwiikhompyutheni ebhodi. Khangela ukusetyenziswa kwepetroli yangoku. Le yindlela elula. Unokuphinde ugwebe ngokuphindaphindiweyo kwe-refueling.
3. Kwaye isibonakaliso sokugqibela sisibane kwideshibhodi ebonisa ubukho bezinto ezingasebenzi kwiinjini.

Ukuba akunakwenzeka ukuhlaziya igesi yokukhupha ngefowuni ekhethekileyo, unokuyenza ngokubonakalayo. Umsi wokukhanya uwuphawu lokuba kuninzi umoya kumxube wamafutha. Umnyama uthetha nge-petroli eninzi. Ngoko ke, umntu unokugweba ukungasebenzi kakuhle kwenkqubo. Kodwa umfanekiso uhlukile, ukuba kukho iprogram ye-lambda. Ngezandla zakho ("Volkswagen", VAZ, "iToyota" - nayiphi na imoto) eso sixhobo senziwe ngokulula.

Izizathu zokuphuka

Kufanelekile ukuthobela ingqalelo ukuba i-oxygen sensor ikhona kwi-epicenter of fuel fuel. Ngenxa yoko, ukubunjwa kwe-petroli kunomphumo obalulekileyo kumsebenzi weprogram ye-lambda. Ukuba i-petroli iqulethe ukungcola okukhulu, ayihambisani neGOST, umgangatho ophantsi, i-oxygen sensor iya kunika impazamo okanye isignali engalunganga kwiyunithi yokulawula i-electronic. Kwimeko embi kakhulu, ifowuni ihluleka. Kwaye kwenzeka oko ngenxa yomxholo ophezulu wokukhokela, ofakwe kwi-sensor kwaye uphazamise ukusebenza kwayo. Kodwa kukho nezinye izizathu zokuphazamiseka:

1. Impembelelo yamatshini - ukunyakaza, ukusebenza ngokunyanisekileyo kwemoto, kubangela umonakalo okanye ukutshiswa komzimba. Akunakwenzeka ukulungisa okanye ukubuyisela, isisombululo esinengqiqo kukuthenga enye entsha kwaye uyifake.
2. Ukusetyenziswa okungalunganga kwenkqubo yokunikezela ngamanzi. Ukuba umxube we-fuel-fuel is not burning completely, i-soot iqalisa ukuhlala emzimbeni weprogram ye-lambda, kwaye iphinda ingene ngaphakathi ngokusebenzisa izimbobo zomoya. Ewe, ekuqaleni kucoca ifowuni inceda. Kodwa ukuba ifuna le nkqubo rhoqo, kuya kufuneka ukuba ufake ifowuni entsha.

Zama ukwenza ukuxilongwa kweemoto zakho ngezikhathi ezithile. Kule meko, awuyi kuba yintsholongwane yokumangalisa nayiphi na into.

Uluhlu lweengxaki

Kakade ke, ukuxilongwa kuphela kwezixhobo ezizodwa kuza kunika impendulo echanileyo malunga nokuphuka. Kodwa ukufumanisa ukuphazamiseka kweso senzwa kunokwenzeka kwaye ngokuzimeleyo, kwanele ukuba ufunde ngokucophelela malunga neempawu zesenzi kunye neempawu zayo. Kodwa kunqabile kakhulu ukuseta inkqubo ye-lambda. Ngezandla zakho (i-VAZ-2114 okanye nayiphi enye imoto ukuba unayo), unokwenza i-stub-bluff kwiindlela eziphuculweyo ngendlela engokoqobo. I-algorithm yokujongana neengxaki ilandelayo:

1. Vula i-hood uze ufumane ubuninzi be-exhaust. Yenza umsebenzi kwi-injini ehlile, njengoko unokulimala kakhulu. Fumana i-lambda probe kwi-converter catalytic.
2. Ukuqhuba uviwo lwangaphandle. Ukungcola, i-soot, iingubo zokukhanya - iimpawu zokusetyenziswa kakubi kwenkqubo yombane. Kwaye uphawu lokugqibela luthi kukho inkokeli enkulu kwiigesi.
3. Shintsha i-oxygen sensor kwaye uphinde uhlolisise yonke inkqubo yombane. Ukuba ukungcola kungabonakali, kufuneka uqhubeke noxilongo.
4. Unqamle iplagi yesikhombisi kwaye udibanise i-voltmeter ngezinga elifikelela kwi-2 volts kuyo. Qala injini kwaye ukwandise isantya ukuya kuma-2500 ngemizuzu, uze uhlawule kwisantya sokungena. Utshintsho lwamandla alufanele lube lukhulu - kwi-0,8 .0,9 volts. Ukuba akukho tshintsho, okanye i-voltage ayiyiyo, ungathetha malunga nokuhluleka kwenzwa.

Kwakhona kunokwenzeka ukuba ugwebe malunga nokuhlukana nezinye iimpawu. Kwiphubhu yocwecwe, udala i-vacuum yokufakelwa. Ngelo xesha, i-voltage kufuneka ibe nezantsi kakhulu-ngaphantsi kwe-0.2 volts.

Izibonelelo zengqondo yeoksijini

Ukuqinisekisa ukuqhutyelwa kokusebenza okungenakuphazamiseka nokuzinzileyo kwemoto, ukuhlolwa rhoqo kobugcisa kuyimfuneko. Ngokomzekelo, iprogram ye-lambda kufuneka ihlolwe iikhilomitha ezingama-30,000. Kwaye akukho mithombo kuyo ayikho ngaphaya kwewaka lamawaka - akuyimfuneko ukugcina imoto kunye negrage endala - iya kuhokelela kuphela ukuba injini kufuneka ihlaziywe ngaphambili. Kwaye umbuzo uvela: Ngaba i-lambda probe fad ihambelana nemoto yakho? Ngezandla zakhe kwi "Kalina" ifowuni enjalo inokwenziwa ngemizuzu embalwa.

Kodwa kukho enye inkalo. Umqhubi angeke aqiniseke ukuba uphethiloli awenzayo imoto unomgangatho ophezulu. Kakade, wonke umntu ujwayele ukuthulula i-petroli esithengiswa kwisikhululo sakhe segesi. Kodwa ngubani owaziyo ukubunjwa kwe-petroli ebhotile apha? Ngoko ke, zama ukuzithemba izitishi zegesi "zityhilo", ezixabisa igama labo. Kodwa ukuba akukho zikhululo zegesi ezifanelekileyo, ngoko kuya kufuneka unelisekile ngezinto ezikhoyo kwicala lakho. Kwaye isibonakaliso se-ICE esitsha esivuthayo-esi siqhelo rhoqo, ukusilahlela oko kuza kunceda ukufaka i-blende.

Isixhobo se-homemade snag

Konke kuxhomekeka kwindlela othetha ngayo. Kubalulekile ukuba uqaphele ukuba umxube weprogram ye-lambda ngezandla zawo kwi-VAZ inokuba yintando yesininzi, isebenza ngokungazelelwe. Isona esincinci - senzeke. Umzimba wethusi uyenziwa. Esi sinyithi sikulungele ukukhetha, kuba sinokumelana nokushisa okukhulu. Yaye ubukhulu beli bhande kufuneka bufane ngokufanayo nenzwa ngokwayo, ukuze imfucuza yokukhupha ingaphumeleli. Enyanisweni, le ndawo isithuba esincinci - akukho ngaphezu kweemitha ezintathu. Esi sikhewu sichazwa kwisithuba senzwa. Kwaye i-lambda probe ngokwayo ifakwe kwi-spacer.

Phakathi kwe-sensor kunye nomngxuma kwi-disc kukho uluhlu lwee-ceramic chips, apho uhla lwe-catalyst lufakwe khona. Ngenxa yoko, igesi yokukhupha igqithisa umgodi omncinci kwaye ixutywe yi-crumb. Isiphumo kukunciphisa okukhulu kumgangatho we-CO. Ngenxa yoko, i-oxygen sensor isingqiqo. Kodwa izixhobo ezinjalo zingafakwa kwiimoto zebhajethi. Amashishini axabisa kakhulu akufanele aguqulwe.

I-electronic blende

Kodwa ukuba unayo izakhono ekufakeni izijikelezo zombane, unokwenza idivaysi eyenziwe ngokwakho. Ufuna enye yezinto ezimbini - umxhatshazi okanye umbane. Kodwa kungekhona yonke into ehambelana neprogram ye-lambda ekhohlisayo. Ngezandla zakho ("i-Subaru Forester" okanye i-VAZ, akunandaba) unokwenza ngokwezicwangciso ezikhethiweyo. Kodwa qaphela, kuba ukungaqondi kakuhle inkqubo yokukhohliswa kuya kuthintela ukusebenza kweyunithi yokulawula yonke. Yaye ukuba awuqinisekanga, ungcono ulungele kumlawuli omncinci. Kuhle ukuba inokuzimela ngokuzimela ngokulandelayo:

1. Linganisa ingxininiso yegesi kwindawo yokuqala.
2. Emva koko, i-pulse yenziwe, ehambelana nomqondiso owafunyanwa ngaphambili.
3. Ubonelela ngeyunithi yokulawula i-electronic, ukuvumela ukuba injini isebenze ngokuqhelekileyo.

I-Firmware yeyunithi yokulawula i-electronic

Indlela efanelekileyo kakhulu yokutshintsha ngokupheleleyo inkqubo ebekwe kwiyunithi yokulawula. Ingundoqo yenkqubo yonke kukukrazula yonke into okanye inxalenye yempendulo yokutshintshwa kwezifundo ezivela kwi-oxygen sensor. Kodwa qaphela ukuba iwaranti ilahlekile kwimoto. Ngoko ke, ukuba oomatshini abatsha banjalo, njengokuba, ngokwenene, nayiphi na enye, ayifani.

Isiphelo

Kwaye kubaluleke kakhulu - cinga, ngaba uyayifanele? Ngaba kufuneka wenze loo nkcukacha nje nge-lambda probe fake ngezandla zakho? "I-Lancer 9", yithi, imoto ayikho isabelomali, kodwa iphakamileyo-ke, ngaba kukho na ukuqonda ukudibanisa idizayini kunye nemveliso eyahlukeneyo? Ingqiqo? Ukuba kukho imali yemoto ebiza, kufuneka kubekho iimali kwaye ugcine ukusebenza. Ukuba akunjalo, kutheni bathenge imoto enjalo?
