Kupanga mafuta 5w40, mwachitsanzo, ali mkulu matenthedwe ndi mankhwala bata. Yotsirizira amatanthauza pakalibe pafupifupi kusinthika chuma (makutidwe ndi okosijeni, mwachitsanzo) pa ntchito ya galimoto ndi. Matenthedwe bata amatchedwa posungira wa kukhuthala pa enaake pa lonse kutentha osiyanasiyana. chizindikiro ichi chikupatsani otetezeka injini chiyambi-mmwamba mu nyengo yozizira. Komanso, mtendere matenthedwe mafuta zipangitsa apamwamba chitetezo cha galimoto ya mu mabacteria mkulu-kutentha pa katundu mkulu ndipo imathamanga mkulu.

Kupanga mafuta (pw) chimasiyana wapadera maselo zikuchokera, ndi amene amaperekedwa mkulu malowedwe luso fluidity. Tikumbukenso kuti injini oiling Choncho sakondwera woposa makumi anayi kapena makumi asanu masekondi. Kugwiritsa ntchito zipangizo mchere, ndondomeko pa kutentha m'munsi zingatenge ambiri angapo Mphindi.

Kupanga mafuta losiyana mkulu kukhuthala index, amene kumatha kudalira kusinthasintha kutentha. Izi kumatha kufunika zina. Iwo ayenera okha kuteteza kutembenuka kwa mafuta mu madzi, popanda kuwongolera katundu lubricating, monga mokulira, ballast.

Kupanga mafuta adzalandira flowability bwino pa kutentha osiyana. ntchito zawo amapereka kochepa mkati kukana kuti kasinthasintha mu galimoto, amene nawonso kumawonjezera mphamvu ndi amachepetsa mafuta.

Kupanga mafuta kupereka cholimba filimu mapangidwe pa kali mbali pansi kukhululukirana. zinthuzi komanso ndi mkulu detergency ndi dispersancy katundu. ndime mafuta ndipo mkati injini yeniyeniyo woyera. Pa kali mkati palibe madipoziti kuti ndi khalidwe la zosakaniza mchere. precipitates zosiyanasiyana zomwe anapanga pa ntchito injini, ndi kusungunuka mafuta. Izi kupewa particles dothi ndi lalikulu, lomwe Iyamba avale a galimoto ndi.

An ntchito zofunika mafuta kupanga akuti ndi kugonjetsedwa kwambiri kukalamba. Choncho, m'malo nthawi kuchuluka.
