Chifukwa chiyani mumafunikira mafuta ochulukirapo agalimoto yanu m'chilimwe
Ndi mafuta ngati 10W40, mafuta amayenda ngati kulemera kwa 10 mu kutentha kwapansi pa zero ndipo amateteza ngati kulemera kwa 40 m'chilimwe. Ndichidziwitso ichi mu makhalidwe a mafuta, kusintha kulemera ndi nyengo sikufunikiranso ndipo kungakhale kovulaza.
Pofika chilimwe ndi kukwera kwa kutentha, tiyenera kumvetsera kwambiri mbali zina zofunika za galimoto yathu zomwe zidzafunika thandizo lowonjezera kuti tidutse nyengoyi popanda mavuto.
Kutentha kwambiri kumatha kusokoneza magwiridwe antchito a injini ndi kukana, choncho ndi bwino kusintha mafuta anu chilimwe chisanayambike ndikugwiritsa ntchito omwe ali oyenera kutentha kwambiri.
Ngati kutentha kupitilira 104º F, ndizotheka kuti mafutawo asunthike mwachangu. Zimachepetsanso mphamvu ya gawo lofunika kwambiri pa injini ya galimoto yathu. Ndi bwino kuyang'anitsitsa mlingo wa mafuta nthawi zonse ndikugwiritsa ntchito yowonjezereka.
Chifukwa chiyani mafuta ochulukirapo agalimoto ndiabwino kugwiritsa ntchito m'chilimwe?
Mafuta ndi nkhani yabodza, mikangano, chidziwitso chachikale komanso nthano kuposa mbali ina iliyonse yokonza magalimoto. Kugwiritsa ntchito mafuta oyenera ndi gawo lofunikira kuti injini yanu ikhale ikuyenda bwino, koma izi zikutanthauza chiyani?
Mafuta wamba anali ndi viscosity imodzi yokha ndipo amachepetsedwa akatenthedwa. Izi zidayambitsa mavuto m'nyengo yozizira chifukwa mafutawo adasanduka ma molasi ndipo mapampu samatha kuyatsa bwino injini.
Pofuna kuthana ndi izi, nyengo yozizira, mafuta opepuka, monga 10 viscosities, ankagwiritsidwa ntchito kuti apitirize kuyenda, pamene ma viscosity olemera 30 kapena 40 anali abwino m'miyezi yachilimwe kuti ateteze mafuta kuti asawonongeke.
Komabe, luso lamakono lapita patsogolo ndipo mafuta asintha, tsopano pali mafuta ochuluka a viscosity omwe amayenda bwino pamene kuzizira, ndiyeno amalimbitsa ndi kuteteza bwino pamene akutentha, abwino kwambiri padziko lonse lapansi.
Mafuta amakono amagwira ntchito bwino pazigawo zonse za kutentha, ndipo injini zatsopano zimapangidwira mwachindunji ndikuyesedwa kuti ziziyenda ndi mtundu wamafuta omwe afotokozedwa m'buku la eni ake. Magalimoto akale amathanso kugwiritsa ntchito mafuta amakono, ingosankhani kukhuthala koyamba kutengera nyengo yomwe mumakhala. Magalimoto ambiri akale amayenda bwino pa 10W30.
