ʻO 5W40 ka aila kūpono loa?

ʻAila ʻenekini i kaha ʻia me ka hōʻailona 5W40 ʻo ia paha ka ʻaila ʻenekini i koho ʻia no nā kaʻa kaʻa. Akā, he aha ke ʻano o kēia pōkole a e hōʻike mau i ka aila maikaʻi loa no kā mākou kaʻa?

He nui nā hana koʻikoʻi o ka ʻaila - ʻoluʻolu nā ʻāpana o ka ʻenekini, e hoemi ana i ka paio a me ka lole kalaiwa, sila nā ʻāpana hoʻoneʻe a mālama pono i ka ʻenekini maʻemaʻe a pale i ka corrosion... ʻO ia ke kumu he mea nui ka hoʻohana ʻana i ka ʻaila e pale pono ai i ka ʻenekini.

ʻO ka pōkole o nā ala, ʻoi aku ka nui o ka ʻaila

ʻO ka hana o ka mīkini e pili pono me ka hana o ka ʻaila. Eia nō naʻe, he mea pono ke ʻike i ka pau ʻana o ka mīkini ʻaʻole i ka wā, no ka laʻana, ke holo nei ke kaʻa i ka wikiwiki ma ke ala nui, akā. i ka wā e hoʻomaka ai a e kinai... No laila, ʻo nā huakaʻi pōkole ka mea paʻakikī loa no ka ʻenekini.

He mea kahaha paha ia, akā inā ʻoe e hoʻokele kaʻa no kahi mamao pōkole, pono ʻoe i kahi ʻaila ʻoi aku ka maikaʻi ma mua o ka hoʻokele ʻana i nā haneli mau kilomita me ka pau ʻole. Mea ʻaila maikaʻi hooloihi i ke ola o na mea enekini hookahia ʻoiaʻiʻo - e ʻae iā ʻoe e hoʻomaka i ka ʻenekini i nā kūlana ʻino loa (no ka laʻana, i ka hau nui).

ʻO ka ʻoi aku ka wela, ʻoi aku ka haʻahaʻa o ka viscosity.

ʻO ka palena nui o ka aila ʻo kona viscosity. I ka wā e wela ai ka ʻaila, e emi ana kona viscosity. Ke maʻalili ka ʻenekini, piʻi ka viscosity.. I nā huaʻōlelo ʻē aʻe - ma nā wela kiʻekiʻe, lilo ka ʻaila ʻaila i ka lahilahi, a ke hoʻohui koke mākou i ka throttle me kahi ʻenekini wela, haʻahaʻa rpm a lawa ʻole ka aila, hiki ke nalowale ka ʻenekini no kekahi manawa!

Eia nō naʻe, aia kekahi pilikia ʻoʻoleʻa loa ka ʻailano ka mea hiki ke hele lohi i nā ʻāpana ʻenekini pākahi.

ʻOi ka 0W no ka hau

Maanei pono mākou e hoʻoponopono i ka haki ʻana e ka pae viscosity. ʻO ka palena me ka leka W (maʻamau mai 0W a 20W) e hōʻike ana i ka viscosity hoʻoilo. ʻOi aku ka liʻiliʻi o ka ʻāpana W, ʻoi aku ka kiʻekiʻe o ka pale hau..

ʻO ka aila 0W ke kū i ka hau nui loa - pono e hoʻomaka ka ʻenekini ma nā mahana ma lalo o -40 degere Celsius. ʻO ka ʻaila 20W ka hana ʻino loa i nā haʻahaʻa haʻahaʻahiki ke pale i ka hoʻomaka ʻana o ka ʻenekini ma -20 degere.

ʻAila ʻenekini mahana

Akā ʻaʻole ʻo ia wale nō, no ka mea he mea koʻikoʻi ka lua. Hōʻike ka helu ma hope o ka leka W ʻaila viscosity ke mahana ka ʻenekini i ka mahana hana maʻamau (ma kahi o 90-100 degere Celsius).

ʻO ka papa viscosity kaulana loa he 5W40.. ʻO ia aila i ka hoʻoilo e hiki ai ke hoʻomaka i ka mīkini ma kahi mahana o -35 degere, a i ka wā i hoʻomehana ʻia, hāʻawi ia i ka viscosity i kūpono no ka hapa nui o nā mana. No ka hapanui - akā ʻaʻole no nā mea āpau!

ʻAila viscosity haʻahaʻa

Ua kapa ʻia nā ʻaila o 20 a i ʻole 30 ʻaila mālama ikehu... ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka haʻahaʻa o ke kūpaʻa ʻaila, ʻo ia hoʻi ka emi ʻana o ka nalowale o ka mana engine. Eia naʻe, i ka wā i wela ai, ua nui lākou kiʻi pale lahilahi.

ʻO kēia haʻahaʻa haʻahaʻa e hiki ai i ka ʻaila ke kahe wikiwiki ma waena o nā ʻāpana ʻenekini, akā i ka nui o nā powertrains, ʻaʻole lawa kēia pale. Ma ia kūlana paʻa wale paha ka ʻenekini.

ʻO ka maʻamau, ninini ʻia nā aila o kēia ʻano i loko o nā ʻenekini hou - hāʻawi ʻia, ʻoiaʻiʻo, ua ʻōlelo ka mea hana e hoʻohana i ka aila o kēia viscosity.

ʻO nā aila viscosity kiʻekiʻe

ʻO nā aila o nā papa 50 a me 60, ma kahi ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka viscosity, no laila, ma ke ʻano o ka ʻōlelo ʻana, ʻike ʻia lākou he "mānoanoa". ʻO ka hopena, hana lākou i kahi ʻāpana ʻoi aku ka mānoanoa o ka ʻaila a ʻoi aku ka maikaʻi o ka pale ʻana i ke kaʻa mai ka overload... Hiki i ka hoʻohana ʻana i ia ʻaila ke loaʻa kahi hopena maikaʻi ʻole i ka hoʻohana ʻana i ka wahie a me ka dinamika.

Hoʻohana pinepine ʻia kēia ʻano ʻaila. i loko o nā ʻenekini ʻino, i loko o ka poʻe "lawe aila". Hiki i nā ʻaila paʻa loa ke hōʻemi i ka hoʻohana ʻana i ka aila a hiki nō hoʻi, ma muli o ko lākou mau waiwai sila, e hoemi i ka neenee ana... Akā, hiki nō hoʻi i nā aila kiʻekiʻe-viscosity paipai ʻia lākou no nā kaʻa haʻukino ka pale pono ʻana i kāu mau drive ikaika a no laila koi.

Pono au e hoʻololi i ka viscosity?

E pane ana i ka nīnau poʻo, ʻAila 5W40 (a i ʻole 0W40) maikaʻi ka brand (e.g. Castrol, Liqui Moly, Elf) ʻo ia ke koho maikaʻi loa i ka nui o nā kūlana.

Hoʻololi no ka ʻaila hoʻoilo kiʻekiʻe-viscosity i ko mākou kūlana climatic ʻaʻohe kumu - hiki ke alakaʻi i nā pilikia me ka hoʻomaka ʻana i ke kaʻa i ka hoʻoilo. ʻO ka mea ʻē aʻe ke makemake mākou i kahi ʻaila me ka viscosity kauwela kiʻekiʻe, a ʻo ia ʻaila he viscosity, no ka laʻana, 10W60.

Ka lālani hoʻololi i ka ʻaila i ka ʻaila me ka viscosity kauwela kiʻekiʻe a haʻahaʻa paha i kekahi manawa kūpono ia (no ka laʻana, me kahi ʻenekini haʻuki, hou loa a i ʻole, ʻoi aku ka kahiko), akā ʻoi aku ka maikaʻi o ka hoʻoholo ʻana ma hope o ka heluhelu ʻana i ka manual o ke kaʻa a me ka nīnau ʻana i kahi mīkini loea.
