Tanthauzo lachidule mu mafuta injini

03.06.2022 /

Mafuta onse ali ndi manambala ndi zidule, zomwe nthawi zambiri sitidziwa zomwe zikutanthauza, ndipo titha kugwiritsa ntchito zomwe sizili zoyenera pagalimoto.

Mafuta a injini ndi amodzi mwamadzimadzi ofunikira kwambiri pakugwira ntchito komanso moyo wautali wagalimoto. Kukonzekera kwanthawi yake komanso kuzindikira kwamafuta kumapangitsa injini yanu kuthamanga komanso kuti isawonongeke chifukwa chosowa mafuta.

Pali mitundu yosiyanasiyana yamafuta, mutha kupeza mafuta pamsika. synthetics kapena mchere, kutengera ntchito yawo, koma kuchokera pamenepo onse ali ndi manambala ndi zidule zomwe nthawi zambiri sitidziwa zomwe akutanthauza ndipo titha kugwiritsa ntchito imodzi yomwe siyikugwirizana ndi galimoto.

Ambiri aife timagwiritsa ntchito mafuta ambiri chifukwa amakwaniritsa miyezo ya SAE pazochitika zonse ziwiri. Iwo ali ndi makhalidwe a mafuta kuwala kwa ntchito yoyenera pa kutentha otsika kwambiri ndi makhalidwe a mafuta olemera kusunga mamasukidwe akayendedwe pa kutentha kwambiri. Izi zimatheka powonjezera zowonjezera pamafuta zomwe zimapangitsa kuti kukhuthala kukwezeke pomwe kutentha kwa injini kumakwera, kukhalabe ndi mafuta a injini nthawi zonse ndi chitetezo,

Ndicho chifukwa chake apa tikuthandizani kuti mudziwe tanthauzo lachidulechi.

  • Dzina loyamba SAE, Society of Automotive Engineering, ali ndi udindo wolembera mafuta a injini kutengera kukhuthala kwawo komanso mphamvu ya injini. mafuta ophikira kuchita ntchito yake malinga ndi kutentha kumene injini adzayamba.
  • La sigla "W", Chidule ichi ndi chamafuta omwe ali oyenera kutentha kwambiri. M'mawu ena, "w" amasonyeza nyengo yozizira kapena nyengo yozizira ndipo ndi mtengo wa viscosity pa kutentha kochepa.
  • Nambala pambuyo pachidule. Chitsanzo: SAE 30 ku 10n 50 Nambala pambuyo chidule limasonyeza mtundu wa mafuta pa kutentha. Izi zikutanthauza kuti, zochokera chidule cha 5W-40, mafuta adzakhala 5 otsika kutentha ndi 40 kutentha mkulu, kutanthauza kuti ali katundu otsika mamasukidwe akayendedwe ndi injini akhoza kuyamba pa kutentha otsika kwambiri.

    • Mukhozanso kupeza zidule monga API SG, amene m'gulu mafuta a injini sitiroko anayi, kapena "API TC", amene m'gulu khalidwe kwa awiri sitiroko injini, ndi achidule. ISO-L-EGB/EGC/EGD ndi mawonekedwe amafuta a injini yapadziko lonse lapansi yamitundu iwiri.
