Ingaba inzwa yeoksijini engaphambili eyaphukileyo iyichaphazela njani imoto
I-sensor ye-oxygen ngaphambili yemoto ephukileyo ayiyi kwenza kuphela ukukhutshwa kwesithuthi kudlula umgangatho, kodwa iphinde ibe mbi ngakumbi imeko yokusebenza kwe-injini, ekhokelela kwi-stall idling stall, injini engafanelekanga, ukunciphisa amandla kunye nezinye iimpawu, kuba i-oxygen sensor njengenxalenye ebalulekileyo. yenkqubo yolawulo lwe-elektroniki yokutofa kwamafutha
Umsebenzi we-oxygen sensor: Umsebenzi osisiseko we-oxygen sensor kukubona i-oxygen concentration kwi-gas yomsila. Emva koko i-ECU (ikhompyutheni yokulawula inkqubo ye-injini) iya kugqiba imeko yokutshisa i-injini (i-pre-oksijeni) okanye ukusebenza kakuhle kwe-converter ye-catalytic (i-post-oxygen) ngokusebenzisa isignali yoxinaniso lwe-oxygen olunikezwa yinzwa ye-oxygen. Kukho i-zirconia kunye ne-titanium oxide.
Ityhefu yesivamvo se-oksijini kukusilela rhoqo kwaye kunzima ukunqanda, ngakumbi kwiimoto ezihamba rhoqo ngepetroli enelothe. Kwanezinzwa zeoksijini ezintsha zinokusebenza kuphela amawaka ambalwa eekhilomitha. Ukuba yimeko encinci yetyhefu yelothe, ke itanki yepetroli engenalo ilothe iya kususa isikhokelo ukusuka kumphezulu we-oxygen sensor kwaye ibuyisele ekusebenzeni okuqhelekileyo. Kodwa rhoqo ngenxa yobushushu obuphezulu bokukhupha, kwaye yenze ilothe ingene ngaphakathi kwayo, ithintele ukusasazwa kweeyoni zeoksijini, yenza ukusilela kwesivamvo se-oxygen, emva koko inokutshintshwa kuphela.
Ukongeza, i-oxygen sensor silicon poisoning yinto eqhelekileyo. Ngokuqhelekileyo, i-silica eyenziwe emva kokutshiswa kweekhompawundi ze-silicon eziqulethwe kwi-petroli kunye ne-oyile yokuthambisa, kunye negesi ye-silicone ekhutshwe ngokungafanelekanga kwe-silicone ye-rubber seal gaskets iya kwenza ukuba inzwa ye-oksijini ingaphumeleli, ngoko ke ukusetyenziswa kweoli ye-oyile esemgangathweni kunye nokuthambisa. ioli.
