Mitundu yamafuta agalimoto: pali chiyani ndipo mungawazindikire bwanji?

Mafuta agalimoto ndi chinthu chopangidwa ndi mafuta oyambira ndi zowonjezera zomwe zimagwira ntchito yofunika kwambiri pa injini.

Mwachitsanzo: kuchepetsa kuvala chifukwa cha mkangano pakati pazinthu zosunthira, kuteteza dzimbiri, kuteteza makina kuti asatuluke, ndikugawa kutentha molondola mpaka kutentha kwa injini kutsika.

Kodi ndi mitundu iti yamafuta yamagalimoto yomwe ilipo komanso momwe mungawadziwire?

Musanagule ndikugwiritsa ntchito mafuta amgalimoto, mvetserani ma code omwe ali pamakalata. Afotokoza cholinga cha mafutawo ndi momwe angawagwiritsire ntchito moyenera.

Kusankha mankhwala oyenera ndi zotheka kokha ngati inu mukudziwa chimene coding mafuta injini ayenera kukhala galimoto yanu molingana ndi makhalidwe a galimoto iliyonse. Mitundu yosiyanasiyana yamafuta agalimoto imatha kugawidwa m'njira zotsatirazi. Tiyeni tione bwinobwino.

Mafuta agalimoto kutengera mtundu wa injini:

• Mafuta a injini ya mafuta. Mafuta agalimoto amenewa amadziwika ndi chilembo S kenako ndi chilembo china chachilembo. Kalata yachiwiri ikuyimira mtundu wake, mukamayendetsa kwambiri, mafuta amafunikira kwambiri. Mwa njira, SN ndiye mtengo wapamwamba kwambiri wamainjini amafuta.
• Mafuta a injini ya dizilo. Mafuta a injini ya dizilo amadziwika ndi kalata. C amatsatiridwa ndi chilembo china cha zilembo. Mofanana ndi mafuta a galimoto ya petulo, ubwino wake umatsimikiziridwa ndi dongosolo la zilembo za zilembo. Cholemba chapamwamba kwambiri ndi CJ-4.

Mafuta agalimoto ndi kalasi ya viscosity:

• Monograde mafuta agalimoto. Mtundu wamafuta amtundu wamagalimoto uli ndi mamasukidwe akayendedwe omwe amatha kukhala 0, 5, 10, 15, 20, 25, 30, 40, 50 kapena 60. Kalasi iyi imakhalabe yotentha.
• Mafuta apadziko lonse lapansi. Mtundu uwu umakhala ndi mamasukidwe akayendedwe osiyanasiyana kutengera kutentha, komwe kumapangitsa kuti kukhale kosalala nthawi yotentha komanso madzi ambiri nthawi yachisanu. Chitsanzo ndi SAE 15W-40, dzina lomwe lili ndi tanthauzo lotsatirali: 15W imayimira kukhuthala kwamafuta pamafuta ochepa. Kutsika kwa chiwerengerochi, kumawonjezera magwiridwe ake kutentha pang'ono; W akuwonetsa kuti mafuta amatha kugwiritsidwa ntchito nthawi yachisanu; 40 imayimira kukhuthala kwamafuta pakatentha kwambiri.

Mafuta agalimoto kutengera kapangidwe kake... Kutengera mtundu wamafuta, mafuta pagalimoto amatha kukhala amchere kapena opanga. Pazinthu izi, palibe zolembera zovomerezeka (kalata yeniyeni) yomwe imatsimikizira kuti mafuta ndi amchere ati ndipo ndi ati omwe amapangidwa. Chizindikiro chokha ndi chomwe chikuwonetsa mtundu wamafuta omwe agulitsidwa.

• Mchere mafuta magalimoto... Ndizopangidwa ndimakina osakomedwa osakaniza ndi zina zowonjezera zowonjezera. Mbali ina ya mafuta amchere ndikuti siyabwino kugwira ntchito pakusintha kwakukulu kwa kutentha, chifukwa imatha kulimba mu injini mu chisanu choopsa. Izi zitha kuyambitsa kuvala panthawi yama injini ozizira. Kuphatikiza apo, ma molekyulu amafuta amafuta amafuta sangafanane. Zotsatira zake, nthawi ina, zimayamba kuwonongeka, ndipo mafuta amasiya msanga kugwira ntchito. Ichi ndichifukwa chake "madzi amchere" amafunikira m'malo mobwerezabwereza, pafupifupi, makilomita 5 aliwonse.
• Kupanga galimoto mafuta... Uku ndiko kaphatikizidwe ka mafuta oyambira kutengera kapangidwe kake, komanso zowonjezera zomwe zimapatsa mphamvu (kuwonjezera kuvala, kuyeretsa, kuteteza dzimbiri). Mafuta oterewa ndioyenera kugwira ntchito muinjini zamakono komanso m'malo ogwirira ntchito kwambiri (kutsika ndi kutentha kwambiri, kuthamanga kwambiri, ndi zina zambiri). Mafuta opangira, mosiyana ndi mafuta amchere, amapangidwa pamaziko a kaphatikizidwe ka mankhwala. Pakapangidwe kake, mafuta osakomoka, omwe ndi chinthu choyambirira, amapukutidwa kenako nkuwasandutsa mamolekyulu oyambira. Ndiye, pamaziko awo, mafuta oyambira amapezeka, omwe amawonjezera zowonjezera kuti chomaliza chikhale ndi mawonekedwe apadera.

Mafunso ndi Mayankho:

Ndi mafuta amtundu wanji agalimoto omwe alipo? Njinga (pawiri sitiroko ndi anayi sitiroko injini), kufala, dizilo (mayunitsi dizilo), mchere, theka-synthetic, kupanga.

Ndi mafuta amtundu wanji omwe amagwiritsidwa ntchito mu injini zamakono? Kwenikweni, magalimoto amakono amagwiritsa ntchito semi-synthetics (Semi-Synthetic) kapena synthetics (Synthetic). Nthawi zambiri, madzi amchere amatsanuliridwa mu injini (Mineral).
