Inzwa ye-oksijini edla emuva imininingwane yokuhlushwa igesi exutshwe ne-ECU ngokuthola okuqukethwe komoya-mpilo kugesi ophelelwe yi-Injini, futhi ifakiwe kwipayipi eliphuma emikhunjini emithathu.

Into ebucayi ye-Oxygen Sensor esetshenziselwa ukukhiqiza i-Volfage Dioxide (i-ZRO2), enesendlalelo seplatinamu endaweni yayo yangaphandle, kanye nongqimba lwama-ceramics ngaphandle kwe-platinamu ukuvikela i-electrode yeplatinamu. Uhlangothi lwangaphakathi lwento ezwakalayo yenzwa ye-oxygen ivezwa emkhathini, futhi uhlangothi lwangaphandle ludlula kugesi ophelelwe yi-expar ekhishwe yinjini. Lapho amazinga okushisa enzwa engaphezulu kwama-300 ℃, uma okuqukethwe kwe-oxygen kuzo zombili izinhlangothi kuhluke kakhulu, kuzokwenziwa amandla ama-electromotive nhlangothi zombili. Okuqukethwe komoya-mpilo ngaphakathi kwenzwa yenzwa kuphakeme ngoba kungena umoya emkhathini. Lapho ingxube icashe, okuqukethwe kwe-oxygen egesi yokuphelelwa yisikhathi kuphakeme. Umehluko wokuqukethwe kwe-oxygen phakathi kwezinhlangothi zombili zenzwa incane kakhulu, ngakho-ke amandla e-electromotive akhiqizwe yiwona amancane kakhulu (cishe ngu-0.1V). Kodwa-ke, lapho ingxube icebile kakhulu, okuqukethwe kwe-oksijini ephepheni lokuphelelwa umoya kuncane kakhulu, umehluko wokuhlushwa umoya-mpilo phakathi kwezinhlangothi zombili zento ebucayi mkhulu, futhi amandla we-electromotive akhiqizwayo nawo aphezulu (cishe nge-0.8V). I-heater ngaphakathi kwenzwa ye-oxygen isetshenziselwa ukushisa into ebucayi ukuze isebenze ngokujwayelekile.

Uma inzwa ye-oksijini ingenakho ukukhishwa kwesiginali noma isinali yokuphuma ayijwayelekile, izokhulisa ukusetshenziswa kwamafutha kanye nokungcolisa i-enjini yenjini, okuholela ngesivinini esingenzi lutho, umlilo ongazinzi. Amaphutha ajwayelekile we-oksijini sensor yile:

1) Ubuthi basemanganese. Yize uphethiloli oholwayo asasetshenziswa, i-agent ye-antiknock ephepheni iqukethe ama-manganese, nama-manganese ion noma i-mangegate ion ngemuva kokuvuselelwa kuzoholela ebusweni bezinzwa ze-oxygen, ukuze zikwazi ukukhiqiza amasiginali ajwayelekile.

2) ukubekwa kwekhabhoni. Ngemuva kobuso bephepha leplatinamu lezinzwa ze-oxygen kufakwe ama-volton-vontage amasignali.

3) Akukho okukhishwe kwamandla kagesi ngemvume ngenxa yokuxhumana kabi noma ukuvula umjikelezo kumjikelezo wangaphakathi wenzwa ye-oksijini.

4) Into ye-ceramic yenzwa ye-oxygen yonakele futhi ayikwazi ukukhiqiza isinali ejwayelekile ye-voltage.

5) Ucingo olumelana ne-Oxygen Sensor heater lushisiwe noma umjikelezo walo uphukile, okwenza inzwa ye-oxygen ayikwazi ukufinyelela ekushiseni okujwayelekile kokusebenza ngokushesha.
