He aha ka lubricant maikaʻi e hoʻohana i ka hoʻoilo a me ke kauwela?

I ka hoʻoilo anuanu, inā pono ʻoe e hoʻololi i ka ʻaila ʻenekini i kūpono i ke kau, ua ʻōlelo ʻia e koho ʻoe i kahi ʻano me ka fluidity haʻahaʻa haʻahaʻa. No ka laʻana, no nā huahana me ka lepili SAE 10, inā aia ʻoe ma kahi ʻāpana anuanu ʻākau (no ka laʻana, aia ka mahana ambient i loko o -28°C), pono ʻoe e koho i nā huahana me ka lepili 10W/30, e like me ka hana o kēlā me kēia lā. lubricants (10W/30; 10W/40) . Inā aia ʻoe ma ka hema kahi i anu ʻole ai ka hoʻoilo (no ka laʻana, aia ka mahana ambient i loko o -18 ° C), hiki iā ʻoe ke koho i nā huahana me ka lepili 15W/40, e like me nā huahana 15W/40 o ka hui lubricant Iapana. .

ʻOi aku ka kiʻekiʻe o ka mahana i ke kauwela, akā ke hoʻohālikelike ʻia i ka mahana kiʻekiʻe o 100 ° C i loko o ka ʻenekini, ʻoi aku ka liʻiliʻi, no laila ʻaʻole pili nui ke koho ʻana i ka aila lubricating i ke kauwela. Ma muli o ka liʻiliʻi o ka viscosity o nā lubricants synthetic i kēia manawa me ka mahana, a ua hoʻonui ʻia ka ʻenehana mīkini i hana ʻia i nā makahiki i hala aku nei a ʻoi aku ka maʻalahi o nā ʻāpana, ʻaʻohe pono o ka lubricant viscosity nui. Ma ka hapa nui o ko mākou ʻāina, hiki iā ʻoe ke koho i nā huahana SAE15W/40. Inā ʻoi aku ka ʻelemakule o kāu ʻenekini a ʻoi aku ka nui o ka ʻeha a me ka waimaka, pono ʻoe e koho i nā huahana SAE20W/50.

Inā pono ʻoe e kūʻaiʻaila mīkini hana hale a i ʻole nā ​​​​mea ʻē aʻe, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa. E lawelawe ʻo CCMIE iā ʻoe me ka naʻau piha!
