Isixhobo sokuvavanya ioksijini esingaphambili esiphukileyo siyichaphazela njani imoto
I-sensor ye-oksijini engaphambili yemoto ephukileyo ayizukwenza nje kuphela ukuba ukukhutshwa komoya ophumayo kwesithuthi kudlule umgangatho, kodwa ikwayenza mandundu imeko yokusebenza kwenjini, nto leyo ekhokelela ekubeni isithuthi singahlali kakuhle, ukungahambi kakuhle kwenjini, ukuncipha kwamandla kunye nezinye iimpawu, kuba i-sensor ye-oksijini njengenxalenye ebalulekileyo yenkqubo yokufaka amafutha olawulo lwe-elektroniki.
Umsebenzi we-oxygen sensor: Umsebenzi oyintloko we-oxygen sensor kukubona ubungakanani be-oxygen kwi-tail gas. Emva koko i-ECU (ikhompyutha yokulawula inkqubo yenjini) iya kugqiba imeko yokutsha kwe-injini (pre-oxygen) okanye ukusebenza kakuhle kwe-catalytic converter (post-oxygen) ngokusebenzisa isignali ye-oxygen concentration enikwa yi-oxygen sensor. Kukho i-zirconia kunye ne-titanium oxide.
Ukutyhefwa kwe-oxygen sensor kukusilela okuxhaphakileyo nokunzima ukukuthintela, ingakumbi kwiimoto ezisebenzisa ipetroli ene-lead rhoqo. Kwane-oxygen sensors ezintsha zinokusebenza kuphela kwiikhilomitha ezimbalwa. Ukuba yimeko encinci yokutyhefwa kwe-lead, itanki yepetroli engenalo i-lead iya kuyisusa i-lead kumphezulu we-oxygen sensor ize iyibuyisele kwisimo sayo esiqhelekileyo. Kodwa rhoqo ngenxa yobushushu obuphezulu kakhulu bokukhupha umoya, kwaye yenze i-lead ingene ngaphakathi kwayo, ithintele ukusasazeka kwee-ion ze-oxygen, yenze i-oxygen sensor ingasebenzi, emva koko inokutshintshwa kuphela.
Ukongeza, ubuthi be-silicon sensor ye-oxygen buyinto eqhelekileyo. Ngokuqhelekileyo, i-silica eveliswa emva kokutsha kwee-silicon compounds ezikwi-petroli kunye ne-oyile yokuthambisa, kunye negesi ye-silicone ekhutshwa kukusetyenziswa okungafanelekanga kwee-gaskets ze-silicone rubber seal ziya kwenza i-oxygen sensor ingasebenzi, ngoko ke ukusetyenziswa kwe-oyile yamafutha esemgangathweni kunye ne-oyile yokuthambisa.
