Kodi sensa ya okosijeni yakutsogolo yosweka imakhudza bwanji galimoto?
Chojambulira mpweya cha kutsogolo kwa galimoto chomwe chasweka sichimangopangitsa kuti mpweya wotuluka m'galimoto upitirire muyezo, komanso chimawonjezera vuto la ntchito ya injini, zomwe zimapangitsa kuti galimoto isagwire bwino ntchito, injini isayende bwino, mphamvu ichepetse komanso zizindikiro zina, chifukwa chojambulira mpweya ngati gawo lofunikira la dongosolo lojambulira mafuta lamagetsi.
Ntchito ya sensa ya okosijeni: Ntchito yaikulu ya sensa ya okosijeni ndi kuzindikira kuchuluka kwa okosijeni mu mpweya wakumbuyo. Kenako ECU (kompyuta yowongolera makina a injini) idzazindikira momwe injini ikuyaka (pre-oxygen) kapena momwe catalytic converter (post-oxygen) imagwirira ntchito kudzera mu chizindikiro cha kuchuluka kwa okosijeni chomwe chimaperekedwa ndi sensa ya okosijeni. Pali zirconia ndi titanium oxide.
Kupha poizoni wa okosijeni ndi vuto lomwe limachitika kawirikawiri komanso lovuta kupewa, makamaka m'magalimoto omwe nthawi zambiri amagwiritsa ntchito mafuta opangidwa ndi lead. Ngakhale masensa atsopano a okosijeni amatha kugwira ntchito makilomita masauzande ochepa okha. Ngati ndi vuto lochepa la poizoni wa lead, ndiye kuti thanki ya mafuta opanda lead imachotsa lead pamwamba pa sensa ya okosijeni ndikubwezeretsa ntchito yake yanthawi zonse. Koma nthawi zambiri chifukwa cha kutentha kwambiri, ndikupangitsa lead kulowa mkati mwake, kuletsa kufalikira kwa ma ayoni a okosijeni, kupangitsa kuti sensa ya okosijeni isagwire ntchito, ndiye kuti ikhoza kusinthidwa kokha.
Kuphatikiza apo, poizoni wa silicon wopangidwa ndi sensa ya okosijeni ndi chinthu chofala kwambiri. Kawirikawiri, silika yomwe imapangidwa pambuyo pa kuyaka kwa zinthu za silicon zomwe zili mu mafuta a petulo ndi mafuta opaka, komanso mpweya wa silicone womwe umachokera pakugwiritsa ntchito molakwika ma gaskets omatira a silicone zimapangitsa kuti sensa ya okosijeni ilephereke, motero kugwiritsa ntchito mafuta abwino amafuta ndi mafuta opaka.
