Kodi 5W40 ndiye mafuta oyenera kwambiri nthawi zonse?

Zamkatimu

Mafuta a injini olembedwa ndi chizindikiro 5W40 mwina mtundu wosankhidwa kwambiri wamafuta a injini zamagalimoto onyamula anthu. Koma chidule ichi chikutanthauza chiyani ndipo nthawi zonse kusonyeza mafuta mulingo woyenera kwambiri galimoto yathu?

Mafuta ali ndi ntchito zambiri zofunika - ozizira magawo osuntha a injini, amachepetsa kukangana ndi kufooka kwa galimoto, zisindikizo kusuntha ziwalo ndipo ngakhale kusunga injini woyera ndi amaletsa dzimbiri... Ichi ndichifukwa chake ndikofunikira kugwiritsa ntchito mafuta omwe amateteza bwino injini.

Njira zazifupi zimakhalanso zofunika kwambiri mafuta

Ntchito ya injini imagwirizana kwambiri ndi ntchito ya mafuta. Komabe, m'pofunika kudziwa kuti injini amatopa kwambiri osati pamene, mwachitsanzo, galimoto ikuyendetsa pa liwiro lalikulu pa msewu, koma poyambira ndi kuzimitsa... Choncho, maulendo afupiafupi ndi ovuta kwambiri kwa injini.

Zingakhale zodabwitsa, koma ngati mukuyendetsa galimoto mtunda waufupi, mudzafunika mafuta abwino kuposa ngati mukuyendetsa makilomita mazana osayimitsa. Mafuta abwino onjezerani moyo wa zigawo za injinindipo ndithudi - zidzakulolani kuti muyambe injini mu nyengo yoipa kwambiri (mwachitsanzo, mu chisanu choopsa).

Kutentha kumakhala, kutsika kwa mamasukidwe ake.

Gawo lalikulu la mafuta ndi kukhuthala kwake. Pamene mafuta akuwotcha, kukhuthala kwake kumachepa. Injini ikazizira, kukhuthala kumawonjezeka.... Mwa kuyankhula kwina - pa kutentha kwakukulu, wosanjikiza mafuta amakhala woonda, ndipo pamene ife mwadzidzidzi kuwonjezera valavu throttle ndi injini otentha, otsika rpm ndi mafuta osakwanira, injini akhoza kutaya chitetezo kwa kanthawi!

Komabe, pangakhalenso vuto mafuta ndi viscous kwambirimonga zingafikire munthu zigawo injini pang'onopang'ono.

0W ndi yabwino kwa chisanu

Apa tikuyenera kuthana ndi kuwonongeka ndi kalasi ya viscosity. Chizindikiro chokhala ndi chilembo W (nthawi zambiri kuchokera ku 0W mpaka 20W) chimasonyeza kukhuthala kwa nyengo yozizira. Zing'onozing'ono W parameter, ndipamwamba kukana chisanu..

0W mafuta kupirira chisanu kwambiri - injini ayenera kuyamba ngakhale kutentha m'munsimu -40 digiri Celsius. Mafuta a 20W amachita zoyipa kwambiri pakatentha kwambirizomwe zingalepheretse injini kuyambira -20 digiri.

Mafuta a injini yotentha

Koma si zokhazo, chifukwa gawo lachiwiri ndilofunikanso. Nambala pambuyo pa chilembo W ikusonyeza mafuta mamasukidwe akayendedwe injini pamene ofunda kutentha kwanthawi zonse (pafupifupi madigiri 90-100 Celsius).

Gulu lodziwika bwino la mamasukidwe akayendedwe ndi 5W40.... Mafuta oterowo m'nyengo yozizira amathandizira kuyambitsa injini pa kutentha kwa madigiri -35, ndipo ikatenthedwa, imapereka mamasukidwe akayendedwe omwe ndi abwino kwambiri pamagawo ambiri amagetsi. Kwa ambiri - koma osati kwa aliyense!

Low mamasukidwe akayendedwe mafuta

Mafuta a magiredi 20 kapena 30 amatchedwa mafuta opulumutsa mphamvu... Kutsika kwa mamasukidwe amphamvu, kumachepetsa kukana kwamafuta, zomwe zikutanthauza kuchepa kwa mphamvu ya injini. Komabe, zikatenthedwa, zimapanga zambiri filimu yoteteza thupi.

Kukhuthala kotsika kumeneku kumapangitsa kuti mafuta aziyenda mwachangu pakati pazigawo za injini, koma mumagetsi ambiri, chitetezo ichi sichingakhale chokwanira. Zikakhala choncho injini ikhoza kungoyimba.

Kawirikawiri mafuta amtunduwu amatsanuliridwa mu injini zamakono - zoperekedwa, ndithudi, kuti wopanga amalimbikitsa kugwiritsa ntchito mafuta a viscosity iyi.

High mamasukidwe akayendedwe mafuta

Mafuta a giredi 50 ndi 60, m'malo mwake, amakhala ndi mamasukidwe apamwamba, motero, mophiphiritsa, amawoneka ngati "okulirapo". Chotsatira chake, iwo amapanga wosanjikiza wandiweyani wa mafuta ndi amateteza bwino mota kuti isachuluke... Kugwiritsa ntchito mafuta oterowo kumatha kukhala ndi zotsatirapo zoyipa pakugwiritsa ntchito mafuta komanso mphamvu.

Mafuta amtunduwu amagwiritsidwa ntchito kwambiri. m'ma injini owonongeka kwambiri, komanso mwa omwe "amatenga mafuta". Mafuta omata kwambiri amatha kuchepetsa kugwiritsa ntchito mafuta komanso ngakhale, chifukwa cha kusindikiza kwawo, kuchepetsa kusuntha kwa injini... Koma zimachitika kuti mkulu-makamaka mamasukidwe mafuta iwo akulimbikitsidwa masewera magalimotokuti muteteze bwino ma drive anu olimba komanso ofunikira.

Ndiyenera kusintha mamasukidwe akayendedwe?

Poyankha funso la mutu, Mafuta 5W40 (kapena 0W40) mtundu wabwino (mwachitsanzo. Castrol, Liqui Moly, Elf) adzakhala chisankho chabwino kwambiri nthawi zambiri.

M'malo kwa mkulu-kukhuthala kwa nyengo yozizira mafuta mu nyengo yathu palibe chowiringula - izi zingayambitse mavuto ndi kuyambitsa galimoto m'nyengo yozizira. Kupatulapo ndi pamene tikufuna mafuta ndi kukhuthala kwa chilimwe, ndipo mafuta ali ndi mamasukidwe akayendedwe, mwachitsanzo, 10W60.

Mzere sinthani mafuta kukhala mafuta okhala ndi kukhuthala kwachilimwe kwapamwamba kapena kutsika nthawi zina zimakhala zomveka (mwachitsanzo, ndi injini yamasewera, yamakono kwambiri kapena, mosiyana, yakale), koma chisankhocho chimapangidwa bwino mutatha kuwerenga buku la galimoto ndikukambirana ndi makina odziwa bwino ntchito.
