Sensor ye okisijeni yekumberi yakatyoka inokanganisa sei mota
Sensor ye okisijeni yepamberi pemotokari yakatyoka haingoiti kuti utsi hwemotokari hupfuure mwero, asiwo ichaita kuti mamiriro ekushanda kweinjini awedzere kuipa, zvichiita kuti mota isashande zvakanaka, injini isashande zvakanaka, simba ridzikire uye zvimwe zviratidzo, nekuti sensor ye okisijeni chikamu chakakosha chesystem yemagetsi yekupinza mafuta.
Basa re sensor yeokisijeni: Basa guru re sensor yeokisijeni nderekuona huwandu hweokisijeni mugasi rekumashure. Zvadaro ECU (engine system control computer) ichaona mamiriro ekupisa kweinjini (pre-oxygen) kana kushanda zvakanaka kwe catalytic converter (post-oxygen) kuburikidza nechiratidzo che oxygen concentration chinopihwa ne sensor yeokisijeni. Kune zirconia ne titanium oxide.
Kukuvadzwa neokisijeni kunonetsa uye kunowanzo tadza kudzivirira, kunyanya mumotokari dzinogara dzichishandisa peturu ine lead. Kunyangwe ma sensor matsva eokisijeni anogona kushanda kwemakiromita mashoma chete. Kana iri nyaya isina lead poison, tangi repeturu risina lead rinobvisa lead pamusoro pe oxygen sensor roidzorera pakushanda kwayo kwakajairika. Asi kazhinji nekuda kwekupisa kwakanyanya, uye kuita kuti lead ipinde mukati mayo, inokanganisa kupararira kwemaion eokisijeni, ichiita kuti oxygen sensor isashande, saka inogona kutsiviwa chete.
Pamusoro pezvo, chepfu yesilicon inoongorora okisijeni inowanzoitika. Kazhinji, silica inogadzirwa mushure mekupiswa kwemakemikari esilicon ari mupeturu nemafuta ekuzora, uye gasi resilicon rinoburitswa nekushandiswa zvisina kunaka kwe silicone rubber seal gaskets zvichaita kuti oxygen sensor ikundikane, saka kushandiswa kwemafuta emhando yepamusoro nemafuta ekuzora.
