1. Ukufakwa kwekhabhoni

Ngenxa yokungashisi kahle kwenjini, amadiphozithi ekhabhoni akhiwa phezu kwenzwa ye-oxygen, noma amadiphozithi anjengamabala kawoyela noma uthuli angena kunzwa ye-oxygen, ezovimbela noma ivimbe umoya ongaphandle ukuthi ungangeni kunzwa ye-oxygen, okwenza isignali yokuphuma kwenzwa ye-oxygen ayilungile, futhi i-ECU ayikwazi ukulungisa isilinganiso se-air-fuel ngesikhathi.Ukufakwa kwekhabhoni kubonakala kakhulu ekwenyukeni kokusetshenziswa kukaphethiloli kanye nokwanda okusobala kokugxiliswa kwe-emission.Ngalesi sikhathi, uma i-sediment isusiwe, izoqala kabusha umsebenzi ojwayelekile.

2. Ukuhlukaniswa kwe-Ceramic yenzwa ye-oxygen

I-ceramic yenzwa ye-oxygen iqinile futhi iyashwabana, futhi ingase iphuke futhi yehluleke uma ishaywa ngento eqinile noma igezwa ngokugeleza komoya okuqinile.Ngakho-ke, ukunakekelwa okukhethekile kufanele kuthathwe lapho kusingathwa, futhi izinkinga kufanele zishintshwe ngesikhathi.

3. Intambo yokumelana ne-heater ishile

Ngenzwa ye-oxygen eshisayo, uma ucingo lokumelana nokushisa luvaliwe, kunzima ukwenza inzwa ifinyelele izinga lokushisa elivamile lokusebenza futhi ilahlekelwe umsebenzi wayo.

4. Isifunda sangaphakathi senzwa ye-oxygen siphukile.

5.Ukuhlolwa kombala wokubukeka kwenzwa ye-oxygen

Khipha inzwa ye-oxygen epayipini lokukhipha umoya, bese uhlola ukuthi imbobo yokukhipha umoya kundlu yezinzwa ivinjiwe futhi i-ceramic core yonakalisiwe.Uma ilimele, buyisela inzwa ye-oxygen.

Iphutha lingahlulelwa futhi ngokubheka umbala wethiphu yenzwa ye-oxygen:

① Ithiphu empunga ekhanyayo: Lona umbala ojwayelekile wenzwa yomoya-mpilo;

② Ithiphu elimhlophe: Kubangelwa ukungcoliswa kwe-silicon, futhi inzwa ye-oxygen kufanele ishintshwe ngalesi sikhathi;

③ Ithiphu ensundu: Ibangelwa ukungcoliswa komthofu.Uma ibucayi, inzwa ye-oxygen nayo kufanele ishintshwe;

④ Ithiphu emnyama: Ibangelwa idiphozithi ye-carbon.Ngemuva kokuthi iphutha lediphozi ye-injini seliqediwe, idiphozi ye-carbon kwinzwa ye-oxygen ingasuswa ngokuzenzakalelayo.

Inzwa ye-oxygen eyinhloko ihlanganisa induku yokushisa yokushisa isici se-zirconia.Induku yokushisisa ilawulwa yikhompyutha (ECU).Uma ukungena komoya kukuncane (izinga lokushisa lokukhipha umoya liphansi), lamanje ligeleza ku-rod yokushisa ukushisa inzwa, ukuze ukugxila kwe-oxygen kutholakale ngokunembile.

Ama-electrode eplatinamu ahlelwe ezinhlangothini zangaphakathi nangaphandle ze-zirconium emise okwethubhu (ZRO2 _ 2).Ukuze kuvikelwe ama-electrode eplatinamu, uhlangothi lwangaphandle lwenjini lumbozwe nge-ceramics, futhi ukugcwala komoyampilo ohlangothini lwangaphakathi kuphakeme kunomkhathi, kuyilapho ukugcwala komoyampilo ohlangothini olungaphandle kuphansi kunokugxilwa kwegesi yokukhipha imoto.
