Mafuta ati omwe ali abwino kwa injini m'nyengo yozizira
Posankha mafuta oyenerera kuti agwiritse ntchito kwenikweni, makamaka m'nyengo yozizira, mauthenga ochokera ku mavidiyo okongola otsatsa sangakhale okwanira. Apa, mwiniwake wagalimoto amafunikira, osachepera, kuti amvetsetse zomwe manambala ndi zilembo zazolemba pabotolo lamafuta zimatanthauza.
Tinene nthawi yomweyo kuti automaker malangizo opaleshoni makina ayenera kusonyeza mtundu wa madzi akulimbikitsidwa, kuphatikizapo lubricant injini. Komabe, ngakhale munthu zikhalidwe ntchito makina inayake zingakhudze kusankha mafuta injini. Ngati agona usiku ndikuyimirira m'galaja yotentha kapena pamalo oimikapo magalimoto mobisa, ndiye kuti simuyenera kuganiza za mafuta apadera m'nyengo yozizira, ngakhale zitachitika kwinakwake ku Siberia - m'dera lomwe lili ndi kutentha kwanthawi yayitali - 30ºС. Koma pamene galimoto amathera moyo wake wonse panja, ndiye ngakhale m'njira yapakati, kumene kuzizira kwa nthawi yaitali kumakhala pansi -20ºС, muyenera kuganizira mozama za kusankha mafuta abwino kwambiri a injini m'nyengo yozizira.
Dziwani kuti popeza tikukamba za injini wokhazikika imayamba nyengo yozizira, mafuta a injini yamchere ayenera kusiyidwa kwathunthu. Sipadzakhala mavuto ndi izi - mu network yogawa tsopano mukufunikirabe kuyang'ana "madzi amchere" oyera a injini. Chosankhacho chingakhale pakati pa mafuta opangira kapena opangidwa ndi semi-synthetic (ndiko kuti, ndi osakaniza a mineral) mafuta agalimoto. "Semi-synthetics", monga lamulo, ndi yotsika mtengo kuposa "synthetics". Komabe, ceteris paribus, ndi bwino kupereka mmalo mokwanira kupanga mafuta. Mfundo ndi yakuti khalidwe lalikulu la mafuta aliwonse injini pa chiyambi ozizira injini ndi fluidity ake.
The mchere chigawo chilichonse mafuta thickens pa otsika kutentha ndi bwino lubricates akusisita pamalo. Ndipo mafuta opangira amatha kukhala okhazikika pamayendedwe otsika komanso otentha kwambiri. Choncho, "synthetics" ndi yabwino m'nyengo yozizira. Popeza tasankha kapangidwe ka mafuta, timalabadira zizindikiro zake za viscosity. Kuti muchite izi, yang'anani zolembedwa pa canister. "Sitidzadzaza" owerenga tsatanetsatane wazomwe amalemba mafuta. Kwa dalaivala wapakati, ndikwanira kudziwa kuti mafuta ambiri amatha kukhala a gulu la "dzinja", pazitini zomwe 0W30, 5W30, 5W40, 10W30 ndi 10W40 zimatchulidwa.
Pakati pawo, 0W30 idzakhala madzi ambiri ozizira, ndipo 10W40 adzakhala wandiweyani. Pachifukwa ichi, mwa njira, sikoyenera kugwiritsa ntchito 15W40 nyengo yozizira mozungulira -20ºС - ndithudi, ngati tikufuna kuwonjezera moyo wa galimoto. Muyenera kusankha mamasukidwe akayendedwe a injini mafuta oyenera zikhalidwe zanu, moganizira zotsatirazi. Pamene galimoto nthawi zina imapezeka mu chisanu kwambiri kapena zochepa chisanu, mwachitsanzo, mu Krasnodar Territory, mafuta kukhuthala 10W40 ndi oyenera injini - kotero kuti m'chilimwe kutentha si madzimadzi kwambiri ndipo akupitiriza. kuteteza malo opaka. Ngati galimoto "amakhala" kwinakwake kupitirira Urals, kumene −25ºС imatengedwa thaw m'nyengo yozizira, ndi bwino kuthira 0W30 mu injini yake. Poganizira monyanyira izi, muyenera kusankha bwino yozizira mafuta.
