Zolemba zamafuta. Ndi chidziwitso chiti chomwe chili chofunikira kwambiri?

Ngakhale zolembera zamafuta agalimoto zitha kuwoneka zovuta, sizovuta kuzimvetsetsa. Mukungofunika kuti muzitha kuwawerenga.

Gawo loyamba loyenera kulabadira ndi mamasukidwe akayendedwe. Zing'onozing'ono ndizochepa, kuchepetsa mafuta ndi kukana kwa injini panthawi yoyambira ndikugwira ntchito. Mafuta a injini okhala ndi mamasukidwe otsika amasankhidwa: 0W-30, 5W-30, 0W-40 ndipo amakhala ndi chitetezo chapadera pa kutentha kochepa. 5W-40 ndi kunyengerera, i.e. sing'anga mamasukidwe akayendedwe mafuta. 10W-40, 15W-40 amatanthauza kukhuthala kwapamwamba komanso kukana kwambiri. 20W-50 ali kukhuthala kwambiri ndi mkulu kuthamanga kukana, komanso chitetezo injini bwino pa kutentha.

Chinthu china ndi khalidwe la mafuta. Makalasi apamwamba amatha kufotokozedwa motsatira miyezo ya ACEA (European Vehicle Manufacturers Association) kapena API (American Petroleum Institute). Oyamba amagawa mafuta omwe amapangidwira injini zamafuta (chilembo A), injini za dizilo (chilembo B) ndi injini zamafuta zokhala ndi makina othandizira, komanso ma injini a dizilo okhala ndi zosefera za DPF (chilembo C). Kalatayo imatsatiridwa ndi chiwerengero cha 1-5 (kwa kalasi C kuchokera ku 1 mpaka 4), makalasiwa amapereka chidziwitso pazitsulo zosiyanasiyana zotetezera kuvala, komanso kukana kwa mafuta mkati, zomwe zimakhudza mwachindunji mafuta.

Pankhani ya magiredi apamwamba a API, mafuta amafuta amafuta amalembedwa ndi chilembo S chotsatiridwa ndi chilembo cha zilembo, mwachitsanzo, SJ (kupitilira chilembocho, kukwezeka kwamafuta). Mofanana ndi mafuta a injini ya dizilo, dzina lawo limayamba ndi chilembo C ndipo limatha ndi chilembo china, monga CG. Mpaka pano, makalasi apamwamba kwambiri a API ndi SN ndi CJ-4.

Onaninso: Momwe mungasungire mafuta?

Opanga magalimoto ambiri amabweretsa miyezo yawoyawo potengera kuyesa kwa injini ya dyno ndi kuyesa kwa msewu. Mitundu iyi ya miyezo ndi Volkswagen, MAN, Renault kapena Scania. Ngati zovomerezeka za wopanga zili pamapaketi, ndiye kuti mafutawo adutsa mayeso okhwima kuti atsimikizire zomwe ali nazo.

Zopakapaka zimathanso kukhala ndi zambiri zamalangizo opanga. Castrol wakhala akugwirizana ndi opanga magalimoto kwa zaka zambiri ndipo ndi mafuta a mtundu uwu omwe akulimbikitsidwa injini zamagalimoto monga BMW, Ford, Seat, Volvo, Volkswagen, Audi, Honda kapena Jaguar, omwe amapezeka osati pamafuta okha. kulongedza, komanso pa kapu yodzaza mafuta m'magalimoto awa.

Onaninso: Iyi ndi Rolls-Royce Cullinan.
