Ulwazi oluyisisekelo lwenzwa yomoya-mpilo kanye nokutholwa nokunakekelwa, konke ngesikhathi esisodwa kuyakutshela!
Namuhla sizokhuluma ngezinzwa ze-oxygen.
Okokuqala, indima yenzwa ye-oxygen
Inzwa ye-oxygen isetshenziswa kakhulu ukuqapha okuqukethwe komoyampilo egesini yokukhipha umoya yenjini ngemva kokusha, futhi iguqule okuqukethwe komoyampilo ibe isignali kagesi eya ku-ECU, ehlaziya futhi inqume ukuhlangana kwengxube ngokuvumelana nesignali, futhi ilungise. isikhathi somjovo ngokwesimo, ukuze injini ikwazi ukuthola ukugxila okuhle kakhulu kwengxube.
I-PS: Inzwa ye-pre-oxygen isetshenziswa kakhulu ukuthola ukuhlangana kwengxube, futhi inzwa ye-post-oksijeni isetshenziswa kakhulu ukuqhathanisa i-voltage yesiginali nenzwa yangaphambili ye-oxygen ukuqapha umphumela wokuguqulwa kwesiguquli se-catalytic yezindlela ezintathu. .
Okwesibili, indawo yokufaka
Izinzwa zomoya-mpilo ngokuvamile zifika ngazimbili, kukhona ezimbili noma ezine, ezifakwe epayipini lokukhipha umoya elinezindlela ezintathu zokuguquguquka kwe-catalytic ngaphambi nangemuva.
3. Isifinyezo sesiNgisi
Isifinyezo sesiNgisi: O2, O2S, HO2S
Okwesine, ukuhlukaniswa kwesakhiwo
Kunezindlela eziningi zokuhlukanisa izinzwa ze-oxygen, i-PS: izinzwa ze-oxygen zamanje ziyashiswa, futhi imigqa yokuqala neyesibili yizinzwa ze-oxygen ezingashisi. Ngaphezu kwalokho, inzwa ye-oxygen iphinde ihlukaniswe phezulu (ngaphambili) inzwa ye-oxygen kanye nenzwa ye-oxygen engezansi (engemuva) ngokuya ngesimo (noma umsebenzi). Izimoto eziningi manje sezifakwe izinzwa zomoya-mpilo ezinezintambo ezi-5 nezingu-6.
Lapha, sikhuluma kakhulu ngezinzwa ezintathu ze-oxygen:
Uhlobo lwe-Titanium oxide:
Le nzwa isebenzisa i-semiconductor material titanium dioxide, futhi inani layo lokumelana lincike ekugxilweni komoyampilo endaweni ezungeze i-semiconductor material titanium dioxide.
Uma kunomoya-mpilo omningi nxazonke, ukumelana kwe-titanium dioxide TiO2 kuyakhula. Ngokuphambene nalokho, lapho umoya-mpilo ozungezile umncane, ukumelana kwe-titanium dioxide TiO2 kuncipha, ngakho ukumelana kwenzwa ye-oxygen ye-titanium dioxide kushintsha kakhulu eduze kwesilinganiso se-air-fuel ratio, futhi i-voltage ephumayo nayo ishintsha kakhulu.
Qaphela: Uma izinga lokushisa liphansi kakhulu, inani lokumelana le-titanium dioxide lizoshintsha libe elingapheli, ukuze i-voltage ephumayo yezinzwa icishe ibe ziro.
Uhlobo lwe-Zirconia:
Izindawo zangaphakathi nezingaphandle zamashubhu e-zirconia zimbozwe ngongqimba lweplatinamu. Ngaphansi kwezimo ezithile (ukushisa okuphezulu kanye ne-platinum catalysis), umehluko ongase ube khona ukhiqizwa umehluko wokuhlushwa womoya-mpilo ezinhlangothini zombili ze-zirconia.
Inzwa ye-oxygen ye-Broadband:
Ibuye ibizwe ngokuthi inzwa ye-air-fuel ratio, inzwa ye-oxygen e-broadband, inzwa ye-oxygen eqondile, inzwa ye-oxygen ehlukahlukene, njll.
PS: Isekelwe ku-zirconia yohlobo lwe-oxygen sensor extension.
