Nā ʻano aila kaʻa: he aha nā mea ma laila a pehea e ʻike ai iā lākou?
ʻO ka aila kaʻa he mea i haku ʻia me ka ʻaila kumu a me nā mea hoʻohui e hana i nā hana koʻikoʻi no kahi mīkini.
ʻO kahi laʻana: hoʻohaʻahaʻa i ka ʻaihue i hoʻokumu ʻia e ka hakakā ma waena o nā ʻoniʻoni e neʻe ana, ka pale ʻana i ka hoʻowahāwahā, ka pale ʻana i ka ʻōnaehana mai nā hoʻokuʻu, a me ka hāʻawi pono ʻana i ka wela a hiki i ka hāʻule ʻana o ka mahana o ka ʻenekini.
He aha nā ʻano o nā aila kaʻa ma laila a pehea e ʻike ai iā lākou?
Ma mua o ke kūʻai ʻana a noi ʻana i ka aila kaʻa, e hoʻolohe i nā code ma nā lepili hōʻailona. E wehewehe lākou i ke kumu o ka aila a pehea e hoʻohana pono ai.
Hiki ke koho i ka huahana kūpono inā ʻike ʻoe i ka coding i ka aila ʻenekini no kāu kaʻa e like me nā ʻano o kēlā me kēia kaʻa. Hiki ke hoʻokaʻawale ʻia nā ʻano aila kaʻa like ʻole ma kēia mau ʻano. E nānā pono kākou.
ʻO nā aila kaʻa e pili ana i ke ʻano o ka ʻenekini:
- ʻAila ʻenekini petroline. Hoʻomaopopo ʻia kēia aila kaʻa e ka huapalapala S e ukali ʻia e kekahi leka o ka pīʻāpā. Hoʻohālikelike ka leka lua i kona ʻano, ʻo ka nui o kou hoʻokele, ʻo ke kiʻekiʻe o ka aila e pono ai. Ma ke ala, ʻo SN ka waiwai kiʻekiʻe loa no nā mīkini ʻenekini.
- ʻAila ʻenekini Diesel. ʻIke ʻia nā ʻaila ʻenekini Diesel me kahi leka. Ua ukali ʻia ʻo C e kekahi leka o ka pīʻāpā. E like me ka aila kaʻa kaʻa, hoʻoholo ʻia kona maikaʻi e ke ʻano o nā leka o ka pīʻāpā. ʻO ka hōʻailona kiʻekiʻe loa ʻo CJ-4.
ʻO nā aila kaʻa e ka papa viscosity:
- ʻAilā kaʻa kaʻa Monograde. ʻO kēia ʻano aila kaʻa he kūlana viscosity kū hoʻokahi i hiki ke lilo i 0, 5, 10, 15, 20, 25, 30, 40, 50 a i ʻole 60. Noho kēia papa i kahi pae mahana paʻa.
- Aila kaʻa holoʻokoʻa. Aia kēia ʻano i nā kekelē ʻokoʻa o ka viscosity ma muli o ka mahana, e ʻae ana iā ia e mānoanoa i ke kauwela aʻoi aku ka wai i ka hoʻoilo. ʻO kahi laʻana ʻo SAE 15W-40, ka inoa o kēia mau ʻano: 15W hōʻike i ka viscosity aila ma nā mahana haʻahaʻa. ʻO ka haʻahaʻa o kēia helu, ʻoi aku ka maikaʻi o kāna hana ma nā mahana haʻahaʻa; W hōʻike i ka aila hiki ke hoʻohana i ka hoʻoilo; Hoʻohālikelike ʻo 40 i ka viscosity aila ma nā mahana wela.
ʻO nā aila kaʻa kaʻa e pili ana i kā lākou hana... Kaukaʻi ʻia i ka ʻano o ka hana, kaʻaila kaʻa hiki ke lilo i mineral a synthetic. I kēia mau hihia, ʻaʻohe coding standardized (leka kikoʻī) e hoʻoholo ana i ka aila he mineral a ʻo ka synthetic. Hōʻike ka lepili wale nō i ke ʻano o ka ʻaila i kūʻai ʻia.
- ʻO kaʻaila Mineral no nā kaʻa... He huahana ia o ka hana ʻaila ʻaila me ka hapa liʻiliʻi o nā mea hoʻohui. ʻO kahi hiʻohiʻona o ka aila mineral ʻaʻole kūpono kūpono ia no ka hana ʻana i nā loli wela nui, ʻoiai hiki ke hoʻopaʻa i ka ʻenekini i ka hau hau ʻino. Hiki i kēia ke hoʻoulu i ka wā o ka hoʻomaka ʻana o ka ʻenekini anu. Eia kekahi, ʻaʻohe homogeneous nā mole o ka aila mole mineral. ʻO ka hopena, i kekahi manawa, hoʻomaka lākou e wāwahi, a nalowale koke ka aila i kāna hana. ʻO ia ke kumu e koi ai ka "wai mineral" i kahi pani pinepine hou, ma ka awelika, i kēlā me kēia 5 kilomita.
- ʻAila kaʻa kemikala... ʻO kēia ka synthesi o nā aila kumu e pili ana i nā synthetics, a me nā mea hoʻohui e hāʻawi iā ia i nā waiwai kūpono (hoʻonui i ke kūpaʻa o ka ʻaihue, maʻemaʻe, pale i ka popopo). Kūpono kēlā mau aila no ka hana i nā ʻenekini hou loa a me nā kūlana hana koʻikoʻi (haʻahaʻa a me nā kiʻekiʻe o ke anawa, ke kiʻekiʻe kiʻekiʻe, a me nā mea ʻē aʻe). Hana ʻia ka aila synthetic, ʻokoʻa ka aila mineral, ma ke kumu o ka synthes kemika i kuhikuhi ʻia. I ke kaʻina hana o ka hana ʻana, kāhinu ka ʻaila maka, ʻo ia ke kumu maʻamau, a laila hana ʻia i loko o nā molakeke kumu. A laila, ma ko lākou kumu, loaʻa kahi aila kumu, kahi i hoʻohui ʻia i nā mea hoʻohui i loaʻa i ka huahana hope loa nā hiʻohiʻona ʻokoʻa.
Nā nīnau a me nā pane:
He aha nā ʻano o nā aila kaʻa? Ke kaʻa (no nā ʻenekini ʻelua-stroke a me ʻehā-stroke), hoʻoili, diesel (no nā ʻāpana diesel), mineral, semi-synthetic, synthetic.
He aha nā aila ʻenekini i hoʻohana ʻia i nā ʻenekini hou? ʻO ke kumu, hoʻohana nā kaʻa hou i nā semi-synthetics (Semi-Synthetic) a i ʻole synthetics (Synthetic). ʻO ka liʻiliʻi pinepine, ninini ʻia ka wai mineral (Mineral) i loko o ke kaʻa.
