Nokuba loluphi uhlobo lwemoto, izinzwa zabo zeoksijini zinentsilelo eqhelekileyo, sikubonelela ngezisombululo ezihambelanayo kunye neengcebiso ezisebenzayo zokuba ugwebe ukusilela.
Ityhefu yesivamvo seoksijini
Khupha iyunithi yezivamvo zomoya evela kumbhobho wokukhupha, kwaye kwakhona ujonge ukuba umngxuma wokukhupha umoya kwipropati yeyunithi yemvakalelo uvalekile na okanye isiseko seceramic sonakalisiwe.Ukuba itshatyalalisiwe ngokwenene, inzwa yomoya kufuneka itshintshwe.Ukuba nje ityhefu encinci ephezulu, ngoko ukusebenzisa ibhokisi yegesi engabonakaliyo inokujongana ne-bait indawo ephezulu yenzwa yomoya kwaye uyibuyisele kwinkqubo eqhelekileyo.Kodwa ngokuqhelekileyo ngenxa yobushushu obuphezulu kakhulu bokukhupha, ilothe ihlasela iindawo zayo zangaphakathi, ezithintela ukuhamba kweeyoni ze-oksijini, kwaye zikwavelisa isivamvo seoksijini esingavelisi nto.Okwangoku, inokutshintshwa ngokulula.
Ukongeza, ityhefu ye-silicon yeeyunithi zokuva ioksijini nayo iyathandwa.Ngokuqhelekileyo ukunxibelelana, i-silicon dioxide eyenziwe ngenxa yokutshiswa kwezinto zesilicon ezibandakanyiweyo kumafutha kunye ne-oyile yokuthambisa kunye namafutha e-silicon ekhutshiweyo evela ekusetyenzisweni okungafanelekanga kweegaskets zeplastiki zerabha ngokuqinisekileyo ziya kubangela ukuba iyunithi yokuva umoya ingahoyi.Ngoko ke, kuyafuneka ukuba kusetyenziswe amafutha asemgangathweni kunye neoli yokuthambisa.Xa ulungisa, khetha kunye nokufakela i-rubber gaskets ngokufanelekileyo, kunye nokwenza ungalawuli izinyibilikisi kunye ne-anti-sticking agents ngaphandle kwezo zichazwe ngumenzi kwiyunithi yokuva.
Ukubekwa kwekhabhoni
Ngenxa yokutsha kwemoto embi, iintlawulo zekharbon diokside zisekwe kumphezulu wesivamvo somoya, okanye iidiphozithi ezibandakanya ioyile okanye ubumdaka obungaphakathi kwinzwa yomoya ngokuqinisekileyo ziya kuthintela okanye zide zithintele isibhakabhaka esingaphandle ukuba singene kwiyunithi yokuva ioksijini. , ukudala isiphumo sesalathisi ngeyunithi yovavanyo lomoya ngokungachanekanga kwaye i-ECU ayinakukwazi ukubekelwa ixesha elifanelekileyo Lungisa umlinganiselo we-fuel yomoya ngokuchanekileyo.Uqinisekiso lweCarbon diokside lubonakaliswa ikakhulu ekwandeni kokusetyenziswa kwepetroli kunye nokonyuka okuqaphelekayo kokugxilwa kokukhupha.Ngeli xesha, ukuba i-debris isusiwe, inkqubo eqhelekileyo iya kubuyela.
Iyunithi yokuva umoya ye-ceramic yonakele
I-ceramic ye-sensor yomoya eneneni inzima kwaye ibuthathaka, kwaye kwakhona ukuhlawulisa into enzima okanye ukuvuthela kunye nomoya okhoyo onamandla kunokuyidala ukuba iqhekeke kwaye iphele ibubuxoki.Ngenxa yoko, qaphela ngakumbi xa uphethe, kwaye uyitshintshe ngexesha ukuba kukho ingxaki.
Intambo yokukhusela iyunithi yokufudumeza ihanjiswa
Kwiyunithi yokuva ioksijini yohlobo lokufudumeza ekhaya, ukuba intambo yokumelana nenkqubo yokufudumeza iye yacinywa ngokwenene, kunzima ngokwenene ukuzisa isivamvo sihlangabezane nobushushu obuqhelekileyo bokusebenza kwaye iphulukane nokusebenza kwayo.
Isiphaluka sangaphakathi seyunithi yokuva umoya siyahlukana
Ukuhlolwa kwembonakalo kunye nomthunzi weyunithi yokuva umoya
Ukuphelisa inzwa yomoya kumbhobho wokukhupha, kwaye ujonge kwakhona ukuba indawo yokuvula umoya kwindawo yokuziva ivaliwe okanye isiseko seceramic sonakalisiwe.Ukuba yonakele, iyunithi yezivamvo zomoya kufuneka ifakwe endaweni yayo.
Iingcebiso
Impazamo inokugwetywa ngokujonga umbala wenxalenye ephezulu yenzwa ye-oxygen:
①Umphezulu ongwevu okhanyayo: lo ngumbala oqhelekileyo we-oxygen sensor;
②Ingcebiso emhlophe: kubangelwa ukungcola kwe-silicon, inzwa ye-oxygen kufuneka ithathelwe indawo ngeli xesha;
③Ingcebiso eBrown: kubangelwa ukungcola okukhokelela, ukuba kunzulu, inzwa ye-oxygen kufuneka itshintshwe;
④Ingcebiso emnyama:kubangelwa yi-carbon deposits.Emva kokuba iphoso yediphozithi ye-injini ye-injini isusiwe, idiphozithi yekhabhoni kwinzwa ye-oxygen inokususwa ngokuzenzekelayo.
I-sensor ye-oxygen ephambili ibandakanya intonga eshushu etshisa i-zirconia element.Intonga yokufudumala ilawulwa yikhompyutha (ECU).Xa i-air intake incinci (iqondo lokushisa eliphantsi lokukhupha), i-current flow flow intonga yokufudumeza ukufudumeza i-sensor ukwenzela ukuba kubonwe ngokuchanekileyo i-oxygen concentration.
I-electrodes ye-Platinum ifakwe kumacala omabini angaphakathi nangaphandle kwi-zirconium element (ZRO2) kwimeko yokuvavanya.Ukuze ukhusele i-electrodes yeplatinam, icala langaphandle lemoto ligqunywe ngeekeramics.Uxinzelelo lwe-oksijini yangaphakathi luphezulu kunomoya, kwaye i-oksijeni yangaphandle iphantsi kune-car exhaust gas concentration.
Kufuneka kucaciswe ukuba emva kokwamkela i-converter ye-catalytic yeendlela ezintathu, i-petroli engabonakaliyo kufuneka isetyenziswe, ngaphandle koko i-converter catalytic converter kunye ne-oxygen sensor iya kuphumelela ngokukhawuleza.Qaphela kwakhona ukuba inzwa ye-oxygen idlala indima ebalulekileyo ekuzinziseni i-throttle kunye nokulungiselela ukuxuba okusemgangathweni.Xa ukutyetyiswa rhoqo okanye ukuxuba okuxubileyo, ikhompyutha (ECU) ayiyi kuhoywa ulwazi lwe-oxygen sensor, kwaye i-oxygen sensor ayiyi kusebenza.
ihoseyile yeVW Oxygen Sensor
Ukugcinwa kunye nokutshintshwa
Ukuhlamba i-throttle yinto yokugcina wonke umntu owaziyo.Enyanisweni, kubaluleke kakhulu ukucoca inzwa ye-oxygen.Emva kwayo yonke loo nto, inzwa ye-oxygen isebenza kwindawo enzima kwaye isengozini yokulimala.Singasathethi ke ukuba ilawula ubungakanani bamafutha atofwayo.I-sensor ye-oksijeni inokucocwa ngokucwilisa i-catalyst ye-3-way-catalyst cleaner imizuzu eyi-10, kwaye emva koko iyomisa ngesomisi seenwele.
Ukuba isivamvo se-oxygen asiphumelelanga, nceda usibuyisele kwangoko.Kwi-VW ene-mileage yeekhilomitha ezili-100,000, kuyacetyiswa ukuba utshintshe inzwa ye-oxygen.Siyingcali ye-VW ye-Oxygen Sensor, ukuba uyayifuna, nceda uqhagamshelane nathi ngokukhawuleza ukuze ufumane isicatshulwa samahhala.
