Inzwa ye-oxygen yangaphambili ephukile iyithinta kanjani imoto
Inzwa ye-oxygen ngaphambili yemoto ephukile ngeke nje yenze ukukhishwa kwemoto yemoto kudlule izinga, kodwa futhi yenze isimo sokusebenza kwenjini sibe sibi kakhulu, okuholela esitokisini semoto, ukungahambi kahle kwenjini, ukunciphisa amandla nezinye izimpawu, ngoba inzwa ye-oxygen njengengxenye ebalulekile yokulawulwa kwe-electronic fuel injection system.
Umsebenzi wenzwa ye-oxygen: Umsebenzi oyisisekelo wenzwa ye-oxygen ukuthola ukugxila komoya-mpilo kugesi lomsila. Khona-ke i-ECU (ikhompyutha yokulawula uhlelo lwenjini) izonquma isimo sokushiswa kwenjini (pre-oksijeni) noma ukusebenza kahle kwesiguquli se-catalytic (i-post-oksijeni) ngokusebenzisa isignali yokuhlushwa kwe-oxygen enikezwa inzwa ye-oxygen. Kukhona i-zirconia ne-titanium oxide.
Ubuthi bezinzwa zomoya-mpilo wukwehluleka okuvamisile futhi okunzima ukukunqanda, ikakhulukazi ezimotweni ezivame ukusebenzisa uphethiloli womthofu. Ngisho nezinzwa ezintsha zomoya-mpilo zingasebenza kuphela amakhilomitha ayizinkulungwane ezimbalwa. Uma kuyicala elincane elinoshevu womthofu, khona-ke ithangi likaphethiloli ongenamthofi lizosusa umthofu ebusweni benzwa ye-oxygen futhi liwubuyisele ekusebenzeni okuvamile. Kodwa ngokuvamile ngenxa yezinga lokushisa eliphakeme kakhulu lokukhipha umoya, futhi wenze umthofu ungene ngaphakathi kwawo, uvimbele ukusakazeka kwama-ion omoya-mpilo, wenze ukwehluleka kwenzwa ye-oxygen, bese kungashintshwa kuphela.
Ngaphezu kwalokho, i-oksijini yenzwa ye-silicon poisoning iyisenzakalo esivamile. Ngokuvamile, i-silica ekhiqizwa ngemva kokushiswa kwezinhlanganisela ze-silicon eziqukethwe kuphethiloli kanye namafutha okugcoba, kanye negesi ye-silicone ekhishwa ukusetshenziswa okungafanele kwe-silicone rubber seal gaskets izokwenza inzwa ye-oxygen ihluleke, ngakho-ke ukusetshenziswa kwamafutha ekhwalithi enhle namafutha okugcoba.
