Inzwa ye-oxygen ibuyisela emuva ulwazi lokugxiliswa kwegesi exutshiwe ku-ECU ngokuthola okuqukethwe komoyampilo kugesi ephumayo yenjini, futhi ifakwa kwipayipi yokukhipha umoya ngaphambi kwe-catalyst yezindlela ezintathu.

Isici esibucayi senzwa yomoya-mpilo esetshenziselwa ukukhiqiza isignali kagesi i-zirconium dioxide (ZrO2), enongqimba lweplatinamu endaweni yayo engaphandle, kanye nongqimba lwezitsha zobumba ngaphandle kweplatinamu ukuvikela i-electrode yeplatinamu. Uhlangothi lwangaphakathi lwenzwa ye-oksijini luvezwa emkhathini, futhi uhlangothi olungaphandle ludlula igesi ephumayo ekhishwa injini. Uma izinga lokushisa lenzwa lingaphezu kuka-300℃, uma okuqukethwe komoyampilo ezinhlangothini zombili kuhluke kakhulu, amandla e-electromotive azokhiqizwa nhlangothi zombili. Okuqukethwe komoyampilo ngaphakathi kwenzwa kuphezulu ngoba kungena umoya emoyeni. Uma ingxube incane, okuqukethwe komoya-mpilo egesini ephumayo kuphezulu. Umehluko wokuqukethwe komoyampilo phakathi kwezinhlangothi ezimbili zenzwa mncane kakhulu, ngakho amandla e-electromotive akhiqizwa yiyo nawo mancane kakhulu (cishe 0.1V). Kodwa-ke, lapho ingxube inothe kakhulu, okuqukethwe komoyampilo egesini yokukhipha umoya kuncane kakhulu, umehluko wokuhlushwa komoyampilo phakathi kwezinhlangothi ezimbili zesici esibucayi mkhulu, futhi amandla e-electromotive akhiqiziwe nawo mkhulu (cishe u-0.8V). I-heater engaphakathi kwenzwa ye-oxygen isetshenziselwa ukushisa into ebucayi ukuze isebenze ngokujwayelekile.

Uma inzwa ye-oxygen ingenawo isignali ephumayo noma isignali yokuphumayo ingavamile, izokhuphula ukusetshenziswa kukaphethiloli kanye nokungcoliswa kombhobho wenjini, okuholela esivinini esingazinzile sokungenzi lutho, ukuqhuma kabi nokukhuluma. Amaphutha ajwayelekile enzwa ye-oxygen yilawa:

1) Ubuthi beManganese. Nakuba uphethiloli onomthofu ungasasetshenziswa, i-antiknock ejenti kuphethiloli iqukethe i-manganese, futhi ama-ion e-manganese noma ama-manganate ion ngemva kokusha azoholela ebusweni benzwa yomoya-mpilo, ukuze ingakwazi ukukhiqiza izimpawu ezivamile.

2) Ukufakwa kwekhabhoni. Ngemuva kokuthi ingaphezulu leshidi leplatinamu lenzwa ye-oxygen lifakwe i-carbon-deposit, amasignali ajwayelekile kagesi awakwazi ukukhiqizwa.

3) Akukho okukhipha amandla esignali ngenxa yokungathintani kahle noma isifunda esivulekile kumjikelezo wangaphakathi wenzwa ye-oxygen.

4) Isici se-ceramic senzwa ye-oxygen sonakalisiwe futhi asikwazi ukukhiqiza isignali evamile ye-voltage.

I-5) Intambo yokumelana ye-heater yenzwa ye-oxygen iyashiswa noma isifunda sayo siphukile, okwenza inzwa ye-oxygen ingakwazi ukufinyelela izinga lokushisa elivamile lokusebenza ngokushesha.
