EYI mea kāhinu,: Mea Maluna a me nā 'ano

Kapa mea kāhinu, - kūikawā papa engine mea kāhinu, mea i hoʻohana 'ia ma kekahi aka wahi o ka kū'ē EYI kaa, e like me ia ma ka likeʻole ma o ke kapa. Hawaii a me ka kapa mea kāhinu, hua mai la i ka mea pōhaku paha kemikala kumu, a laila, doped me keʻano o nā mea hoʻonui, akā, ma luna o ka EYI koi, no ka mea, ka mea hana i mea kiekie wahie, a me ka mämä holo i ka 'oihana o ke kū'ē surfaces. Kekahi o ka loa nui nā hoailona o ia mau mea kāhinu, o ka hiki ke hana i kekahi aiiay Auana ma luna o ka ili o ke kū'ē 'iniha, e pale aku me mechanical hui' ma waena o lākou. Ke hypoid kapa mea kāhinu, i hoʻohana 'ia, i, komo i loko o ka Nine Inch naoh me na surfaces o nā māhele, pale ia skipanie e komo lōʻihi puʻe waiwai. Ma ana, kapa mea kāhinu, oxidize, a lilo ua hoʻohaumiaʻia a me ka Pono, e ke auou caiaiai ke kamepiula. Kēia Ua manaoia i ka e pono ia i ka aila a me ka haʻahaʻa ka welelau o ka'okesaside. No kekahi mau Manufacturers hoʻohana okoa mea hoʻonui i ka hui lākou me nā huahana hiki ole. A hiki ke kūapoʻana i ka EYI mokuna E e ho'ōla loa holoi, ina he mea hiki i ka ia me kaʻaila hou.

Kapa mea kāhinu, i hoʻolaha kekahi (viscosity) a ma Auana. Penei, e like me ka SAE (Ka Hui o kaʻa nā kānakaʻenehana) ka mea, ua māheleʻia i loko o eiwa papa - elima ke kau a me ka eha hooilo (me ka 'inideka W). No kēlā me kēia papa i hoakaka ia (viscosity) inideka. SAE SAE 70W a me 250, no ka laʻana. Pālua 'inideka i hōʻike mai no ka multigrade mea kāhinu, (SAE 80W-90, etc.).

API (Americanʻaila kā Institute) i hookaawale ai i kaʻaila i loko o 6 papa, ke kaumaha ma muli o ka hana ana waiwai - GL-1 ... GL-6. Mau papa e like me ka poe hoʻohana 'ia i loko o ka Soviet GOST 17479.2-85 TM1 ... TM6. ʻO ka lima, a me ka ono o ka pūʻulu e hoʻohana no ka hypoid kona kapa, a i ka mea kiekie loa lubricity a me ka lōʻihi puʻe lawelawe.

Ka wā koho kahunapule mea kāhinu, e kālele ana kuhikuhi ma luna o kā lākou mau hana ana. Inā ka papa mea haʻahaʻa ma mua pono, wale keʻano papa hana ke aloha, a me ka luna o ka aila papa mai i ka oi aku waiwai e lilo aku, a e alakai i ka kāki kawowo aku i. Ua mea i nui, e noonoo i ka mahana i a ka EYI e hana, a ma luna o kēia kumu, e koho i kekahi lubricant. SAE 85W, no kekahi laʻana, e hana ma mahana i -12 ° C, a me 85W mai e -40 ° C. Ma 'akomi transmissions , he hana haʻahaʻa-(viscosity) wai, no laila,ʻaʻohe engine a EYI aila loaʻa mai e pili.

I kēia mau lā ma luna o ka mea kuai i ka nui huahelu o Manufacturers kaumaha lākou kapa mea kāhinu, - Lukoil, Total, Texaco, Reksol, Norse, a he nui na mea e ae. Aʻano o nā mea hoʻonui i hoʻohana e hoʻoholo i ka nui o ka pono o ka mea kāhinu, a me kā lākou kumukuai huahelu. Mea pōhaku i IeAUPIIe, IAa IO ho'ēmi, akā, ua emi synthetics like me kēia nui ke ku pono. A maikaʻiʻae like hoʻokuʻu ma kahai makemake laila e kalaka nui-synthetics like me ka hauʻoli meakino ma waena o ka mea mua elua. Ua E hoi e wary o fakes, aʻaʻole kuai kaʻaila i loko o ka hale kūʻai he palupalu. Hoʻololi i ka pahu i mau oi pipiʻi ma mua o ka lawe i ka pono e like ai kaʻaila, oi loa, ano, i ka hope o ka i, e puku ia hanaiia'na o lakou e 60 tausani kilomika a oi.
