Hiki iaʻu ke hoʻohana i ka aila 5w40 ma kahi o 5w30?
Nā mea
ʻO kekahi o nā nīnau kaulana loa i waena o nā kaʻa kaʻa ka hoʻololi ʻana o nā aila kaʻa. Ma nā ʻaha kūkā he nui, hiki iā ʻoe ke loaʻa nā nīnau maʻamau e like me: "hiki ke hoʻopiha i ka aila 5w40 ma kahi o 5w30?", "Hiki paha ke hoʻohui i ka wai mineral me nā synthetics a i ʻole semi-synthetics?" a laila. Ua pane mua mākou i ka nui o kēia mau nīnau ma kā mākou pūnaewele Vodi.su, a ua nānā pū mākou i nā kikoʻī i nā hiʻohiʻona o ka māka SAE o nā aila kaʻa. Ma kēia kumuhana, e ho'āʻo mākou e noʻonoʻo inā ʻae ʻia ka hoʻohana ʻana o 5w40 ma kahi o 5w30.
ʻO nā aila mīkini 5w40 a me 5w30: nā ʻokoʻa a me nā ʻano
Pono e hōʻike ʻia ka hōʻailona YwX, kahi o "y" a me "x" ma nā kini o ka ʻenekini a i ʻole ka aila hoʻouna. ʻO kēia ka SAE (Society of Automobile Engineers) viscosity index. ʻO ke ʻano o nā huaʻōlelo i loko.
- ʻO ka hua'ōlelo Latin W kahi pōkole no English Winter - winter, ʻo ia hoʻi, ka wahie a me nā lubricants, kahi a mākou e ʻike ai i kēia leka, hiki ke hoʻohana ʻia i nā mahana sub-zero;
- ʻO ka huahelu mua - ma nā hihia ʻelua ʻo ia ka "5" - hōʻike i ka liʻiliʻi o ka mahana kahi e hāʻawi ai ka ʻaila i ka crankshaft cranking a hiki ke hoʻomoʻi ʻia ma o ka ʻōnaehana wahie me ka ʻole o ka hoʻomehana hou ʻana, no ka 5W0 wahie a me nā lubricants kēia helu mai -35 ° C ( pumpability) a me -25 °C (huli);
- ʻo nā huahelu hope (40 a me 30) hōʻike i ka liʻiliʻi o ka wela a me ka paʻa ʻana o ka wai.
No laila, ʻaʻole paʻakikī ke koho, e like me ka hoʻokaʻawale ʻana o ka SAE, ʻo nā ʻaila ʻenekini e pili ana kekahi i kekahi a he liʻiliʻi ka ʻokoʻa ma waena o lākou. Papa inoa mākou no ka maopopo ma ke ʻano o kahi papa inoa:
- 5w30 - hoʻopaʻa i ka viscosity i nā mahana ambient i ka pae mai ka liʻiliʻi 25 a me 25 degere;
- 5w40 - i hoʻolālā ʻia no kahi ākea ākea mai ka liʻiliʻi 25 a hoʻohui i 35-40 degere.
E hoʻomaopopo ʻaʻole nui ka palena wela o luna e like me ka mea haʻahaʻa, no ka mea, piʻi ka mahana hana o ka ʻaila i loko o ka mīkini i 150 degere a ma luna. ʻO ia hoʻi, inā loaʻa iā ʻoe ka ʻaila Mannol, Castrol a i ʻole Mobil 5w30 i hoʻopiha ʻia, ʻaʻole ia he manaʻo i ka wā o kahi huakaʻi i Sochi, kahi e piʻi ai ka mahana ma luna o 30-40 degere i ke kauwela, pono e hoʻololi koke ia. Inā noho mau ʻoe i kahi anuanu wela, a laila pono ʻoe e koho i nā wahie a me nā lubricants me kahi helu lua kiʻekiʻe.
A ʻo kekahi ʻokoʻa koʻikoʻi ma waena o kēia mau ʻano lubricants ʻo ka ʻokoʻa o ka viscosity. ʻOi aku ka viscous o ka haku mele 5w40. No laila, ʻoi aku ka maʻalahi o ka hoʻomaka ʻana i kahi kaʻa ma nā haʻahaʻa haʻahaʻa inā hoʻopiha ʻia kahi aila liʻiliʻi liʻiliʻi - i kēia hihia, 5w30.
No laila hiki ke ninini i 5w30 ma kahi o 5w40?
E like me nā nīnau ʻē aʻe e pili ana i ka hana o nā kaʻa, nui nā pane a ʻoi aku ka nui o nā "akā". No ka laʻana, inā he kūlana koʻikoʻi, ʻae ʻia ka hui ʻana i nā ʻano wahie like ʻole a me nā lubricants, akā ma hope o ia mea pono ʻoe e hoʻomaʻemaʻe loa i ka ʻenekini. No laila, no ka hāʻawi ʻana i ka ʻōlelo aʻoaʻo ʻoi loa, pono e nānā i ke kūlana ʻenehana o ke kaʻa, nā ʻōlelo a ka mea hana, a me nā kūlana hana.
Hoʻopaʻa inoa mākou i nā kūlana i hiki ʻole ai ke hoʻololi i ka aila me kahi viscosity index viscosity kiʻekiʻe, akā i kekahi manawa pono wale nō:
- i ka wā lōʻihi o ka hana ʻana o ke kaʻa ma nā wahi me kahi ea wela;
- me ka holo ma ka odometer oi aku mamua o 100 tausani kilomika;
- me ka hāʻule o ka hoʻoemi ʻana i ka ʻenekini;
- ma hope o ka hoʻoponopono ʻana i ka ʻenekini;
- ma ke ʻano he holoi no ka wā pōkole
ʻOiaʻiʻo, ma hope o ka hala ʻana o 100 tausani mau kilomita, hoʻonui nā āpau ma waena o nā pistons a me nā paia cylinder. Ma muli o kēia, aia ka nui o ka lubricant a me ka wahie, kahi hāʻule o ka mana a me ka paʻi. ʻO nā wahie a me nā lubricants ʻoi aku ka nui o ke kiʻiʻoniʻoni o ka mānoanoa nui ma nā paia e hōʻemi i nā āpau. No laila, ma ka hoʻololi ʻana mai 5w30 a i 5w40, e hoʻomaikaʻi ʻoe i ka hana hoʻoikaika a hoʻonui i ke ola o ka mana. E hoʻomanaʻo i ka ʻaila ʻoi aku ka ʻoi aku o ka hoʻoikaika ʻana i ka crankshaft, no laila ʻaʻole e emi nui ka pae hoʻohana wahie.
ʻO nā kūlana kahi i makemake ʻole ʻia ai ka hoʻololi ʻana mai 5w30 a i 5w40:
- i nā ʻōlelo aʻoaʻo, ua pāpā ka mea hana i ka hoʻohana ʻana i nā ʻano wahie a me nā lubricants;
- he kaʻa hou mai ka hale kūʻai aku ma lalo o ka palapala hoʻokō;
- emi i ka ea wela.
ʻO ka pōʻino loa no ka ʻenekini ke kūlana o ka hui ʻana i nā lubricants me nā ʻano wai like ʻole. ʻAʻole lubricates wale ka ʻaila i nā ʻili, akā hoʻopau pū kekahi i ka wela. Inā hoʻohui mākou i ʻelua mau huahana me nā ʻokoʻa fluidity a me nā coefficient viscosity, e wela ka mīkini. Pili loa kēia pilikia no nā ʻāpana mana kiʻekiʻe o kēia wā. A inā ma ke keʻena lawelawe e hāʻawi ʻia ʻoe e hoʻopiha i ka 5w30 ma kahi o 5w40, me ka hoʻoikaika ʻana i kēia me ka nele o ke ʻano o ka lubricant i makemake ʻia i loko o ka hale kūʻai, ʻaʻole pono ʻoe e ʻae, no ka mea, ma hope o kēlā mau manipulations e piʻi ka wela, ʻo ia hoʻi. piha me ka lehulehu o na pilikia pili.
haʻina
Ma muli o nā mea a pau i luna, hiki mākou i ka hopena o ka hoʻololi ʻana i kekahi ʻano o ka wahie a me nā lubricants hiki ke hiki wale ma hope o kahi noiʻi kikoʻī o nā ʻano o ka mana a me nā koi o ka mea hana. He mea pono e pale i ka hui ʻana i nā lubricants mai nā mea hana like ʻole a ma nā kumu like ʻole - synthetics, semi-synthetics. He pōʻino kēlā ʻano hoʻololi no nā kaʻa hou. Inā nui ka mileage, pono e kūkākūkā me nā loea.
