Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Mphete ya Piston ndi mphete yachitsulo yomwe imayikidwa poyambira pisitoni. Pali mitundu iwiri ya mphete za pisitoni, mphete zophatikizira ndi mphete zamafuta.
Mphete yopondereza itha kugwiritsidwa ntchito kusindikiza mpweya wosakanikirana woyaka muchipinda choyaka. Mphete yamafuta imagwiritsidwa ntchito pochotsa mafuta ochulukirapo mu silinda.
✔Njira yoyezera kumveka kolakwika kwa mphete ya pisitoni
01) Kupopera kwachitsulo kwa mphete ya pulagi
▶ Piston ring ikathyoka, kapena kusiyana pakati pa piston ring groove ndi piston ring groove kumakhala kwakukulu, kumapangitsa kugogoda kwina.
▶Pamwamba pa kuvala kwa silinda, mphete ya pisitoni ndi silinda sizingafanane ndi malowo pafupifupi osavala kuti apange sitepe, monga kukonza kolakwika kwa mphete ya pisitoni ndi sitepe ya silinda kutulutsa osayankhula "poof, poof" kumveka kwachitsulo, ndi kuwonjezeka kwa liwiro, phokoso limakulanso.
02) Pali phokoso la kutayikira mu mphete ya pistoni
▶ Zoyambitsa ndi mawonekedwe: kukhathamira kwa mphete ya pisitoni kumachepa kotero kuti mphete ya pistoni ndi khoma la silinda zisasindikizidwa mwamphamvu, kutsegula kwa mphete ya pisitoni ndi yayikulu kwambiri kapena kupindikirana kolowera, ndipo khoma la silinda limakhala lokhala ndi mipopo, yomwe zidzapangitsa kuti mphete ya piston itayike.
▶Njira yoyezera zolakwika: Lowetsani mafuta opaka pang'ono mu silinda, ngati phokoso lichepa kapena kutha, koma posakhalitsa kuwoneka, ndiko kuti, mphete ya piston yatuluka.
03) Phokoso lachilendo chifukwa cha kuchuluka kwa kaboni mu mphete za pistoni
▶Mawonekedwe a mawu: Kuchuluka kwa mpweya wa carbon ndi phokoso lambiri, ndi phokoso lakuthwa "treble, treble". Kumveka, injini nthawi zina zimakhala zovuta kuyimitsa.
▶Chomwe chimapangitsa kuti mpweya wa carbon: chifukwa chachikulu ndi chakuti mphete ya piston ndi cylinder wall seal ndizosalimba, malo otsegulira ndi aakulu, mphete ya piston imayikidwa chammbuyo, kutsegula kumadutsana, mafuta opaka mafuta amayamba chifukwa cha kuyaka. chipinda, kapena chifukwa chizindikiro cha mafuta sichikukwaniritsa zofunikira, kusakaniza kumakhala kolimba kwambiri, chotsukira mpweya chimakhala chodetsedwa kwambiri.
▶Kuyesa kwa silinda imodzi yokha, phokoso limachepa, koma silizimiririka, ikani screwdriver pa spark plug kapena nozzle kuti mumvetsere, monga "snap, snap" phokoso lingadziwike ngati mphete ya pisitoni yasweka.
▶ Kuyang'anitsitsa mosamala, monga phokoso la "poof, poof", ndipo palibe kusintha pambuyo pa kuphulika kwa moto, kungadziwike kuti piston ring ring cylinder silinda.
▶Galimoto yoziziritsa injini ikayamba, imamveka kuti "boom, boom". Utsi wabuluu ukhoza kuwoneka pa doko lodzaza mafuta, ndipo ma frequency ake amagwirizana ndi ma frequency amawu. Pamene kuyesa kwamoto kumachitidwa, phokosolo limatha, ndipo utsi pa doko lodzaza mafuta umachepa kapena kutha.
▶ Kutentha kwa injini kumakwera, ngati pamakhala phokoso lodziwika bwino la gasi, ndiyeno kuyesa kuphulika kwa moto, koma pamakhala chodziwika bwino chotuluka pa doko lodzaza mafuta, zitha kutsimikiziridwa kuti mphete ya piston ndi silinda khoma chisindikizo. ndi osauka.
✔Kuwunika kwachilendo kwa mphete ya pistoni
▶Pistoni mphete yathyoka.
▶Pistoni kuvala mphete ndi poyambira, zomwe zimapangitsa kuti msana ndi mathero ziloledwe, kutsekeka kwa pisitoni ndi silinda kumachepetsedwa.
▶Chipupa cha silinda chikatha kuvala, phewa lapamwamba limawonekera. Pambuyo pokonzanso chingwe cholumikizira ndodo, mphete ya pistoni ndi phewa la silinda zimagundana.
▶Kuloledwa kwa madoko a piston ndi yayikulu kwambiri kapena madoko a mphete iliyonse amalumikizana ndi doko lina.
▶Kutanuka kwa mphete ya pisitoni ndikochepa kwambiri kapena khoma la silinda limakhala ndi poyambira.
▶ Mphete ya pisitoni imamatirira panjira ya pisitoni.
