Inzwa ye-oksijini ulwazi oluyisisekelo nokutholwa nokulungiswa, konke ngakukutshela!
Namuhla sizokhuluma ngezinzwa ze-oxygen.
Okokuqala, indima yenzwa ye-oxygen
Inzwa ye-oksijini ikakhulukazi isetshenziselwa ukuqapha okuqukethwe komoya-mpilo kugesi ophumayo wenjini ngemuva kokuhlangana, futhi iguqula ukuqukethwe kwe-oxygen kube yisiginali se-voltage ku-ecu, bese ilungisa isikhathi somjovo ngokwesimo.
I-PS: I-Sensor yangaphambi kwe-oxygen isetshenziselwa ikakhulukazi ukuthola ukugxila kwenhlanganisela, futhi inzwa ye-post-oxygen isetshenziselwa ukuqhathanisa i-voltal voltar nge-pre-oxygen inzwa ye-pre-oxygen ukuqapha umphumela wokuguqulwa we-catalytic wendlela amathathu.
Okwesibili, isikhundla sokufaka
Izinzwa ze-oksijini ngokuvamile zingena ngababili, kukhona ezimbili noma ezine, ezifakiwe epayipi lokuphela kwezindlela ezintathu ze-catalytic ezindleleni ngaphambi nangemva kwalokho.
3. Isifinyezo sesiNgisi
Isifinyezo sesiNgisi: O2, O2S, HO2S
Okwesine, ukwakheka kwesakhiwo
Kunezindlela eziningi zokuhlukanisa izinzwa ze-oxygen, i-PS: Izinzwa ze-oksijini zamanje ziyafudumala, futhi imigqa yokuqala neyesibili ayizinzwa ze-oksijini ezingashisi. Ngaphezu kwalokho, inzwa ye-oksijini ibuye ihlukaniswe inzwa ye-oxygen (ngaphambili) ye-oxygen ye-upstream (ngaphambili) i-towntstream (emuva) inzwa ye-oxygen ngokwesikhundla (noma umsebenzi). Izimoto eziningi neziningi zifakwe izinzwa ze-oxygen ezi-5 ne-6-wire boardband.
Lapha, ikakhulu sikhuluma ngezinzwa ezintathu ze-oksijini:
Uhlobo lwe-titanium oxide:
Le sensor isebenzisa i-semiconductor yezinto ze-semiconductor titanium dioxide, futhi inani layo lokumelana lincike ekuhlungeleni komoya-mpilo emvelweni ezungeze izinto ze-semiconductor titanium dioxide.
Lapho kukhona umoya-mpilo ozungezile, ukumelana kweTitanium Dioxide Tio2 kuyanda. Ngokuphambene nalokho, lapho i-oksijini ezungezile incane, ukumelana kweTitanium Dioxide Tio2 kuyancipha, ngakho-ke ukumelana kwe-titanium dioxide oxygen inzwa evuselelayo eduze kwesilinganiso se-theoretical air-fuel ratio, kanye ne-voltage ekhipha futhi kushintsha kakhulu.
QAPHELA: Lapho izinga lokushisa liphansi kakhulu, inani lokumelana le-titanium dioxide lizoshintsha liye ku-infinity, ukuze i-voltage yokuphuma ye-sensor icishe ibe ngu-zero.
Uhlobo lwe-Zirconia:
Izindawo ezingaphakathi nangaphandle zamashubhu e-zirconia zihlanganiswe ngesendlalelo seplatinamu. Ngaphansi kwemibandela ethile (izinga lokushisa eliphakeme neplatinamu catalysis), umehluko ongaba khona ukhiqizwa umehluko we-oksijini ezinhlangothini zombili ze-zirconia.
Inzwa ye-Broadband Opygen:
Ibizwa nangokuthi inzwa yomoya kaphethiloli, inzwa ye-Broadband Opygen, inzwa ye-oxygen ebanzi, inzwa enkulu yo-oxygen, njll.
I-PS: Kususelwa ekunwetshisweni kwezinzwa zezinzwa ze-zirconia ze-zicronia.
