1. Ukubekwa kwekhabhoni

Ngenxa yokuvuselelwa okumpofu kwenjini, kwakhiwa amadiphozi e-carbon ebusweni bezinzwa ze-oxygen, noma ama-deposits anjengezinzwa zika-oxygen noma uthumele inzwa ye-oxygen, futhi i-ECU ayikwazi ukulungisa isilinganiso samafutha e-oxygen ngesikhathi. I-Carbon Desition iboniswa ikakhulukazi ekwandeni kokusetshenziswa kukaphethiloli kanye nokwanda okusobala kokugxila kokuphuma. Ngalesi sikhathi, uma ukusulwa kususwa, kuzoqhubeka nomsebenzi ojwayelekile.

2. Ukuhlukaniswa kwe-Ceramic kwenzwa ye-oxygen

I-ceramic ye-oxygen sensor inzima futhi i-brittle, futhi ingahle iphule futhi yehluleke uma ingqongqozwa ngento enzima noma igezwe nge-airflow eqinile. Ngakho-ke, kufanele kuthathwe ukunakekelwa okukhethekile lapho kuphathwa, nezinkinga kufanele zishintshwe ngesikhathi.

I-3. I-heater ukumelana nocingo kushisiwe

Ngezinzwa ze-oxygen ezifudumele, uma i-heater ukumelana ne-wire ibilisiwe, kunzima ukwenza inzwa ukuthi ifinyelele ekushiseni okujwayelekile kokusebenza futhi ilahlekelwe ukusebenza kwayo.

I-4. Isifunda sangaphakathi senzwa ye-oxygen yephukile.

5.insUction of ukubukeka umbala we-oxygen sensor

Susa inzwa ye-oxygen kusuka epayipi eliphelelwe amandla, bese ubheka ukuthi umgodi wokuzwa usezindlini zenzwa uvinjiwe kanti umnyombo we-ceramic ulimele. Uma kulimele, buyisela inzwa ye-oxygen.

Iphutha lingahlulelwa futhi ngokubheka umbala wethiphu yenzwa ye-oxygen:

① Ithiphu empunga ekhanyayo: Lona umbala ojwayelekile we-oxygen sensor;

Ithiphu Emhlophe: Kubangelwa ukungcoliswa kwe-silicon, futhi inzwa ye-oksijini kumele ithathelwe indawo ngalesi sikhathi;

③ Ithiphu Ensundu: Kubangelwa ukungcoliswa kokuhola. Uma kubucayi, inzwa ye-oksijini kumele futhi ithathelwe indawo;

④ Ithiphu Emnyama: Kubangelwa yidiphozi yekhabhoni. Ngemuva kokuthi iphutha lediphozi le-enjini liyasuswa, idiphozi lekhabhoni kusenzweni se-oksijini lingasuswa ngokuzenzakalelayo.

Inzwa enkulu ye-oksijini ifaka induku yokushisa yokushisa into ye-zirconia. Induku yokushisa ilawulwa yikhompyutha (ECU). Lapho i-air yokuphuza incane (amazinga okushisa aqede aphansi), ukugeleza kwamanje enduku yokushisa ukushisa inzwa, ukuze kutholwe kahle i-oxygen.

Ama-electrodes weplatinamu ahlelwe ezinhlangothini zangaphakathi nezangaphandle ze-zirconium element (ZRO2 _ 2). Ukuze uvikele ama-electrodes weplatinamu, uhlangothi olungaphandle lwemoto lumbozwe ngo-ceramics, futhi okuhlushwa umoya-mpilo ohlangothini lwangaphakathi kuphakeme kunobuso, ngenkathi ukugcotshwa komoya-mpilo ohlangothini lwegesi olungaphandle kwemoto.
