spark plugs, omwe amadziwika kuti mapulagi oyaka moto, amatha kugwira ntchito ngati kutulutsa kwamphamvu kwamphamvu kwa piezoelectric kuchokera pamoto wothamanga kwambiri (pulagi yamoto), yomwe imaphwanya mpweya pakati pa ma elekitirodi a ma spark plugs, kupangitsa kuti magetsi aziyaka. kusakaniza kwa gasi mu silinda.Mikhalidwe yoyambira ya injini yogwira ntchito kwambiri: mphamvu yayikulu yokhazikika, kusakaniza kofanana, chiŵerengero chapamwamba cha psinjika.Magalimoto okhala ndi injini zoyatsira mkati nthawi zambiri amagwiritsa ntchito mafuta a petulo ndi dizilo.Pamsika wamagalimoto ku China, magalimoto amafuta amakhala ambiri.Ma injini a petulo ndi osiyana ndi injini za dizilo chifukwa petulo ili ndi poyatsira moto (pafupifupi madigiri 400), zomwe zimafuna kuyatsa mokakamiza kuti muyatse kusakaniza.Kupyolera mu kumaliseche pakati ma elekitirodi kubala zipsera, mafuta injini ndi mwa mafuta ndi gasi osakaniza kuyaka nthawi yake kupanga mphamvu, koma monga mafuta mafuta ngakhale mu malo kutentha ndi zovuta mowiriza kuyaka, kuti kuyaka yake yake ndi zofunika kugwiritsa ntchito "moto" kuyatsa.Apa kuyatsa kwa spark ndi ntchito ya "spark plug".
