Kungakhathaliseki ukuthi hlobo luni lwemoto, izinzwa zazo zokwenza umoya-mpilo zinokuhluleka okuvamile, sikunikeza izixazululo ezihambisanayo kanye namathiphu asebenzayo ukuze wahlulele ukwehluleka.
Ubuthi benzwa ye-oksijini
Khipha iyunithi yenzwa yomoya evela epayipini le-exhaust, futhi uhlole ukuthi imbobo yokukhipha umoya endaweni yeyunithi yenzwa ivinjiwe ngempela noma i-ceramic primary ilimele ngempela.Uma empeleni ichithekile, inzwa yomoya kufanele ishintshwe.Uma nje kuwubuthi obuphezulu obuncane, khona-ke ukusebenzisa ibhokisi legesi elingenayo i-unleaded kungabhekana ne-bait indawo engaphezulu yenzwa yomoya futhi uyibuyisele kunqubo evamile.Nokho ngokuvamile ngenxa yezinga lokushisa eliphakeme kakhulu lokukhipha umoya, umthofu uhlasela izingxenye zawo zangaphakathi, okuvimbela ukujikeleza kwama-ion omoya-mpilo, futhi ukhiqize inzwa yomoya-mpilo engakhiqizi.Njengamanje, ingashintshwa kalula.
Ngaphezu kwalokho, ubuthi be-silicon beyunithi yokuzwa umoya-mpilo empeleni nayo iyathandwa.Ngokujwayelekile ukuxhumana, i-silicon dioxide edalwe ngenxa yokushiswa kwezinto ze-silicon ezifakwe kuphethiloli kanye namafutha okugcoba kanye namafutha e-organic silicon aphuma ekusetshenzisweni okungafanele kwama-gasket erabha epulasitiki azokwenza ukuthi iyunithi yezinzwa zomoya inganaki.Ngakho-ke, empeleni kuyadingeka ukusebenzisa uphethiloli wekhwalithi enhle namafutha okugcoba.Lapho ulungisa, khetha futhi ufake ama-gasket enjoloba ngendlela efanele, futhi unganikezi izincibilikisi nama-anti-sticing agents ngaphandle kwalawo achazwe umenzi kuyunithi yezinzwa.
Ukufakwa kwekhabhoni
Ngenxa yokusha kwezimoto ezimbi, izinkokhelo ze-carbon dioxide eziphansi empeleni zisekelwe phezu kwenzwa yomoya, noma ngisho namadiphozithi ahlanganisa uwoyela noma ukungcola okungaphakathi kwenzwa yomoya nakanjani kuzovimbela noma kuvimbele isibhakabhaka esingaphandle ukuthi singangeni kuyunithi yokuzwa komoyampilo. , ukudala okukhiphayo kwenkomba ngeyunithi yenzwa yomoya ngokungaqondile kanye ne-ECU ngeke ikwazi ukubekwa isikhathi kahle Lungisa isilinganiso sikaphethiloli womoya ngendlela efanele.Ukuqinisekiswa kwe-Carbon dioxide empeleni kubonakala kakhulu ekwenyukeni kokusetshenziswa kukaphethiloli kanye nokwenyuka okuphawulekayo kokugxila kokukhipha.Ngalesi sikhathi, uma imfucumfucu isusiwe, inqubo evamile izobuyela kuyo.
Iyunithi ye-ceramic yenzwa yomoya yonakele
I-ceramic yenzwa yomoya empeleni inzima futhi ithambile, futhi ukuhlawulisa into eqinile noma ukuvunguza kanye namandla omoya kungase kuyidale ukuthi iqhekeke futhi igcine ingamanga.Ngenxa yalokho, qaphela ikakhulukazi lapho uphatha, futhi uyiguqule ngesikhathi uma empeleni kunenkinga.
Ikhebuli yokuvikela iyunithi yokushisisa iyasakazwa
Kuyunithi yenzwa ye-oxygen yohlobo lokushisisa ekhaya, uma intambo yokumelana nesistimu yokushisisa icishiwe, empeleni kunzima ukuletha inzwa ihlangabezane nezinga lokushisa elijwayelekile lokusebenza futhi ilahlekelwe ukusebenza kwayo.
Isekhethi yangaphakathi yeyunithi yokuzwa emoyeni ihlukanisiwe
Ukuhlolwa kokubukeka nomthunzi weyunithi yenzwa yomoya
Khipha inzwa yomoya epayipini le-exhaust, uphinde uhlole ukuthi ukuvuleka kwesikhala somoya endaweni yeyunithi yezinzwa kuvinjiwe ngempela noma i-ceramic primary yonakele ngempela.Uma ilimele, iyunithi yenzwa yomoya idinga ukushintshwa ngempela.
Amathiphu
Iphutha lingahlulelwa futhi ngokubheka umbala wengxenye ephezulu yenzwa ye-oxygen:
①Ingaphezulu elimpunga elikhanyayo: lona umbala ojwayelekile wenzwa ye-oxygen;
②Ithiphu emhlophe: okubangelwa ukungcola kwe-silicon, inzwa ye-oxygen kufanele ishintshwe ngalesi sikhathi;
③Ithiphu ensundu: okubangelwa ukungcoliswa komthofu, uma kubi kakhulu, inzwa ye-oxygen kufanele ishintshwe;
④Ithiphu emnyama:kubangelwa amadiphozithi ekhabhoni.Ngemuva kokuthi iphutha lediphozi ye-injini seliqediwe, amadiphozithi e-carbon kunzwa ye-oxygen ngokuvamile angasuswa ngokuzenzakalelayo.
Inzwa ye-oxygen eyinhloko ihlanganisa induku eshisayo eshisa isici se-zirconia.Induku yokushisisa ilawulwa yikhompyutha (ECU).Uma ukudonsa komoya kukuncane (izinga lokushisa eliphansi le-exhaust), lamanje ligeleza liye endaweni yokushisisa ukuze kushise inzwa ukuze kunikwe amandla ukutholwa okunembile kokugxila komoyampilo.
Ama-electrode eplatinamu afakwe ezinhlangothini zombili zangaphakathi nangaphandle ze-zirconium element (ZRO2) esimweni seshubhu lokuhlola.Ukuze kuvikelwe ama-electrode eplatinamu, uhlangothi lwangaphandle lwenjini lumbozwe nge-ceramics.Ukugxiliswa komoyampilo wangaphakathi kuphakeme kunomkhathi, futhi ukugxiliswa komoyampilo wangaphandle kuphansi kunokugxiliswa kwegesi yokukhipha imoto.
Kufanele kuphawulwe ukuthi ngemva kokwamukela i-converter ye-catalytic yezindlela ezintathu, uphethiloli ongenayo i-unleaded kufanele usetshenziswe, ngaphandle kwalokho ukuguqulwa kwe-catalytic yezindlela ezintathu kanye nenzwa ye-oxygen kuzohluleka ngokushesha.Qaphela futhi ukuthi inzwa ye-oxygen idlala indima ebalulekile ekuqiniseni i-throttle nokulungiselela ukuxuba okujwayelekile.Lapho ukunothisa okuvamile noma ukuxubana okunciphile, ikhompyutha (ECU) izoziba ulwazi lwenzwa ye-oxygen, futhi inzwa ye-oxygen ngeke isebenze.
I-VW Oxygen Sensor
Isondlo nokushintshwa
Ukugeza i-throttle yinto yokunakekela wonke umuntu owaziyo.Eqinisweni, kubaluleke kakhulu ukuhlanza inzwa ye-oxygen.Phela, inzwa ye-oxygen isebenza endaweni eqinile futhi isengozini yokulimala.Ayisaphathwa-ke ilawula inani likaphethiloli elijovwe.Inzwa ye-oxygen ingahlanzwa ngokucwilisa isicoci se-catalyst sendlela ezintathu imizuzu eyi-10, bese sisomisa ngesomisi sezinwele.
Uma inzwa ye-oxygen yehlulekile, sicela uyishintshe ngokushesha.Ngemoto yohlobo lwe-VW enebanga elingamakhilomitha angu-100,000, kuyanconywa ukuthi ingene esikhundleni senzwa ye-oxygen.Singumkhiqizi ochwepheshe we-VW Oxygen Sensor, uma uyidinga, sicela usithinte ngokushesha ukuze uthole isaphulelo samahhala.
