Nā ʻaila no nā kaʻa haʻuki

ʻOi aku ka nui o nā kaʻa me ka mana ʻenekini kiʻekiʻe ma nā alanui Polani. Hoʻokaʻawale ʻia ka hoʻolālā ʻana o nā mīkini kaʻa haʻuki e ka pololei o ka hana a me ke ʻano kiʻekiʻe o nā mea pili. Ke ulu nei ka hopena a me nā koi kūikawā no nā aila kaʻa.

ʻOkoʻa nā koi lubricant e ka hoʻolālā ʻenekini. I nā ʻenekini kiʻekiʻe loa, e like me nā mea i hoʻohana ʻia i nā kaʻa Formula One, nā aila me ka viscosity o -1W-5 (e ʻōlelo: emi 5W-10) me ka haʻahaʻa haʻahaʻa HTHS index (kiʻekiʻe wela viscosity). Pono nā ʻaila o kēia ʻano i nā pamu maikaʻi loa, nā mea paʻa paʻa mīkini, a me nā ʻōnaehana lubrication kiʻekiʻe loa. Eia naʻe, hōʻoiaʻiʻo lākou i ka haʻahaʻa kūloko kūloko o ka mīkini a kōkua i ka loaʻa ʻana o ka mana kiʻekiʻe loa.

Ma kekahi ʻaoʻao, ʻoi aku ka maikaʻi o nā aila viscosity kiʻekiʻe e like me 10W-60 a i ʻole ke kiʻekiʻe aʻe i nā hoʻolālā he nui. ʻAʻole loaʻa i kēia mau ʻano aila nā waiwai mālama ola, akā ʻae lākou iā ʻoe e uku i nā ʻokoʻa o ka mīkini kūpono. ʻO ka viscosity kiʻekiʻe o kaʻaila e hiki ai i ka mea i kapaʻia he sealing o nā mea engine i emi iho i ke koʻikoʻi o ka wela a loaʻa i kahiʻoluʻolu, a me kahi kiʻekiʻe loa o ka ukana a he mea nui ka hoʻololiʻana i ke kūpono. ʻO kahi hiʻohiʻona o kahi mea i kau ʻia i nā haʻahaʻa kiʻekiʻe loa he piston, i ka wā i hoʻomehana ʻia, e hoʻonui i kona mau ana, e hoʻopili pono ai i ka liner cylinder.

ʻO ke koho ma waena o nā ʻaila haʻahaʻa haʻahaʻa a me nā ʻaila kiʻekiʻe-viscosity ma muli o ke kumu o ka mīkini. ʻO nā aila viscosity haʻahaʻa ke koho ʻia no ka mīkini, i hoʻolālā ʻia no kahi kumu waiwai pōkole a ʻo ka mea nui o ka mea hoʻokele ka mana o ka mea e hōʻemi i ke kūʻē o ka mana. Mahalo i kēia, hiki ke loaʻa i kekahi mau horsepower hou aʻe. Eia nō naʻe, ʻo ka hoʻohana ʻana i nā lubricants me ka haʻahaʻa haʻahaʻa o ka ʻaila viscosity e komo i nā kumukūʻai hana kiʻekiʻe loa no nā ʻāpana ʻenekini. ʻO nā mea kūpono i nā ʻenekini i lubricated me kēia mau ʻaila he pololei loa a pono e koho pono ʻia nā mea. Eia kekahi, ʻo ka viscosity aila haʻahaʻa e hōʻike ana i kahi ola pōkole o ke ʻano mīkini holoʻokoʻa. I nā haʻuki e like me ka Formula 1 ʻae ʻia kēia, a ʻo kēia ʻenehana ke alakaʻi nei i ke ala i nā mīkini kaʻa haʻuki o kēia lā.

Ma ka ʻaoʻao ʻē aʻe, ʻo ke koho ʻana i kahi aila me ka viscosity kiʻekiʻe loa he nui nā pono e pili ana i ka uku ʻana no nā pae ʻenekini like ʻole. Kū'ē lākou i nā loli nui i ka mahana hana. ʻO nā aila me nā hiʻohiʻona hana hou, no ka laʻana, me ka viscosity o 10W-60, e ʻae iā ʻoe e hoʻomaka i ka ʻenekini ma nā mahana ma lalo o -30ºC, a i kekahi manawa -40ºC. I ka manawa like, ʻaʻole ʻae ka viscosity kiʻekiʻe e haehae i ka papa pale o ke kiʻi ʻaila i ka wā e lubricating ai nā mea i hoʻouka ʻia me ka thermally, e like me nā pistons a i ʻole nā ​​ʻāpana turbocharger. Hāʻawi ka thermal stability i kahi kiʻekiʻe o ka pale ma luna o ke ola lawelawe lōʻihi.

ʻAno ʻaila

ʻAʻole pili wale nā ​​mea pale o ka ʻaila i ka viscosity o ka ʻaila. ʻO kahi hoʻohālikelike koʻikoʻi ka maikaʻi o ka aila, kahi i hilinaʻi nui ʻia i nā ʻaila kumu a me nā pūʻulu hoʻohui. ʻO nā aila ʻenekini hou, e like me Castrol EDGE 10W-60, e hana maikaʻi i ka hana lōʻihi ma nā wela kiʻekiʻe, ma lalo o nā haʻahaʻa kaumaha a me nā wikiwiki kiʻekiʻe. ʻO nā aila i hoʻohana pinepine ʻia i nā kaʻa haʻuki he esters. He mau kumu synthetic. Loaʻa iā lākou nā palena kiʻekiʻe ma mua o nā aila synthetic maʻamau (e pili ana i ka PAO). Mahalo i kēia mau kumu, aia nā waiwai o ka aila ma kahi kiʻekiʻe loa, a ʻo ka ʻeke hoʻohui e hiki ai iā ʻoe ke hoʻokō i nā pono palekana a me ka hoʻomaʻemaʻe kūpono, a me ka paʻa ma lalo o nā kūlana hana maʻamau. ʻO ia ʻano kūpaʻa ʻokoʻa, no ka laʻana, ka haʻahaʻa haʻahaʻa o ka ʻaila, no laila, ʻoiai i nā mahana hana kiʻekiʻe loa, ʻaʻole hoʻololi ka ʻaila i kona ʻano kino a me ke kemika. Hoʻonui ka pale ʻana i ka ʻaʻahu kiʻekiʻe, ʻoiai ʻo ka wehe ʻana a me ka maikaʻi o nā huahana kuni a me ka wahie i puhi ʻole ʻia e mālama i ka maʻemaʻe.
