Zilembo zamafuta

Mwambi woti “amene amapaka magiya” ndi wofunika kwambiri pankhani yamafuta agalimoto.

Kukhazikika kwa mphamvu yamagetsi sikutengera mtundu wa mafuta okha, komanso kusankha kolondola kwa injini inayake. Injini yamakono komanso yamphamvu ndi injini yosiyana kotheratu yomwe imasonyeza zizindikiro za kuvala kwakukulu imafuna mafuta osiyana.

Ntchito yayikulu yamafuta ndikuthira mafuta ndikuletsa kulumikizana kwachindunji pakati pa zinthu ziwiri zomwe zimagwirizana. Dulani mafuta osanjikiza, i.e. kuswa zomwe zimatchedwa. Filimu yamafuta imatsogolera ku kuvala kwa injini mwachangu kwambiri. Kuphatikiza pa kudzoza, mafuta amazizira, amachepetsa phokoso, amateteza ku dzimbiri, kusindikiza ndi kuchotsa zonyansa.

  Momwe mungawerenge mafuta

Mafuta onse amagalimoto amatha kugawidwa m'magulu atatu: mineral, semisynthetic and synthetic. Mafuta aliwonse amafotokozera magawo angapo oyambira, monga kalasi ndi mamasukidwe akayendedwe. Kalasi yabwino (nthawi zambiri ndi API) imakhala ndi zilembo ziwiri (mwachitsanzo SH, CE). Yoyamba imatanthawuza injini yomwe mafuta amapangidwira (S kwa mafuta, C kwa dizilo), ndipo yachiwiri ikufotokoza za kalasi yabwino. Kukwera kwa zilembo za zilembo, kumapangitsa kuti mafuta azikhala apamwamba (mafuta a SJ ndi abwino kuposa SE, ndipo CD ndi yabwino kuposa CC). Ndi chizindikiro cha SJ/CF, itha kugwiritsidwa ntchito pamainjini amafuta ndi dizilo. Gawo lachiwiri lofunika kwambiri ndilo gulu la viscosity (nthawi zambiri SAE), lomwe limatsimikizira kutentha komwe kungagwiritsidwe ntchito. Panopa amapangidwa pafupifupi mafuta multigrade okha, kotero chodetsa tichipeza mbali ziwiri (mwachitsanzo, 10W-40). Yoyamba yokhala ndi chilembo W (0W, 5W, 10W) ​​ikuwonetsa kuti mafuta amapangidwa kuti azigwiritsidwa ntchito m'nyengo yozizira. Kutsika kwa chiwerengerocho, mafuta amayenda bwino pa kutentha kochepa. Gawo lachiwiri (30, 40, 50) limafotokoza kuti mafuta atha kugwiritsidwa ntchito m'chilimwe. Kukwera kuli, m'pamenenso kugonjetsedwa ndi kutentha kwambiri. Ndi kukhuthala kolakwika (mafuta ochuluka kwambiri kapena ochepa kwambiri), injini imatha kulephera mwachangu. Mafuta amchere nthawi zambiri amakhala ndi kukhuthala kwa 15W-40, theka-synthetic 10W-40, ndi mafuta opangira 0W-30, 0W-40, 5W-40, 5W-50.

  Zosankha Zosankha

Posankha mafuta, choyamba muyenera kuganizira magawo ake, osati mtundu, ndi kutsogoleredwa ndi malangizo a wopanga galimoto (mwachitsanzo, VW, miyezo 505.00, 506.00). Mukhoza kugwiritsa ntchito mafuta abwino kwambiri, koma osati oipitsitsa. Palinso mafuta a injini omwe akuyenda pa gasi wa liquefied, koma sikoyenera kuwagwiritsa ntchito, ndikwanira kuona kusintha kwa mafuta komwe kumagwiritsidwa ntchito mpaka pano.

Mafuta opangira ma injini ndi abwino kwa injini zatsopano komanso zogwiritsidwa ntchito chifukwa amapereka chitetezo chabwino cha injini, amakhala nthawi yayitali komanso osagwirizana ndi machitidwe ovuta kwambiri. Mafutawa ali ndi kutentha kwakukulu kotero kuti injiniyo imatenthedwa bwino pozizira kwambiri komanso kutentha. Kwa injini zodzaza kutentha, monga injini zamafuta a turbocharged, mafuta okhala ndi mamasukidwe a 10W-60 angagwiritsidwe ntchito, omwe amalimbana ndi kutentha kwambiri.

Ngati injini ili ndi mtunda wautali ndipo ikuyamba "kutenga" mafuta, sinthani kuchokera ku synthetics kupita ku semi-synthetics. Ngati izi sizikuthandizani, muyenera kusankha mchere. Kwa mainjini owonongeka kwambiri, pali mafuta apadera amchere (monga Shell Mileage 15W-50, Castrol GTX Mileage 15W-40) omwe amasindikiza injini, kuchepetsa kugwiritsa ntchito injini ndikuchepetsa phokoso.

Mukamagwiritsa ntchito mafuta amchere omwe si abwino kwambiri, kuthira mafuta opangira mu injini yoteroyo, yomwe ili ndi zinthu zabwino zoyeretsera, kumayambitsa kupsinjika kwa injini ndikutsuka ma depositi. Ndipo izi zingayambitse kutsekeka kwa ngalande zamafuta ndi kupindika kwa injini. Ngati sitikudziwa chimene mafuta anadzazidwa, ndi injini alibe mtunda mkulu, ndi otetezeka kutsanulira theka-synthetics, amene alibe kuopsa monga synthetics, ndi kuteteza injini kuposa mafuta mchere. Kumbali ina, ndikotetezeka kudzaza injini yamtunda wautali ndi mafuta amchere abwino. khalidwe. Pankhaniyi, chiopsezo chotsuka chimbudzi ndi kutsegula ndi chochepa. Palibe malire enieni a mtunda omwe mungasinthe kuchokera ku zopangira kupita ku madzi amchere. Zimangotengera momwe injiniyo ilili.

Timayang'ana mlingo

Mulingo wamafuta uyenera kuyang'aniridwa pa 1000 km iliyonse, ndipo makamaka nthawi iliyonse mukadzaza kapena musanapitirize ulendo wanu. Pamene kuli kofunikira kuwonjezera mafuta, koma sitingathe kugula mafuta omwewo, mungagwiritse ntchito mafuta ena, makamaka amtundu womwewo ndi kalasi ya viscosity. Ngati sizili choncho, tsanulirani mafuta ndi magawo omwe ali pafupi kwambiri.

Ndi nthawi yoti mulowe m'malo?

Kuti injini ikhale ndi moyo wautali wautumiki, sikokwanira kugwiritsa ntchito mafuta olondola, iyeneranso kusinthidwa mwadongosolo, malinga ndi malingaliro a wopanga. M'magalimoto ena (monga Mercedes, BMW) kusintha kumatsimikiziridwa ndi kompyuta kutengera momwe mafuta alili. Iyi ndiye njira yabwino kwambiri, chifukwa m'malo mwake mafutawo amataya magawo ake.
