Mafuta a injini 5w30 vs 5w40 ndi kusiyana kotani

M'nkhani ino tiyankha funso, kusiyana 5w30 ndi 5w40 injini mafuta. Mwachiwonekere, yankho la "viscosity" silingafanane ndi aliyense, choncho tikukupemphani kuti muyang'anenso nkhaniyi, popeza pali malingaliro olakwika kwambiri apa. Mwa njira, gwero la malingaliro olakwikawa ndi kupita patsogolo kofulumira, mwachitsanzo, zaka 10-15 zapitazo, malinga ndi xxW-xx parameter, zinali zotheka kudziwa kuti ndi mafuta amtundu wanji - mineral, synthetic kapena semi-synthetic. . Masiku ano, opanga amatha kupanga mafuta amagulu osiyanasiyana, koma ndi magawo omwewo. Ndizotheka kupeza 10w40 onse semi-synthetic ndi madzi amchere.

Choyamba, tiyeni timvetsetse tanthauzo la zilembo 5w-30.

Kodi 5w-30 ndi 5w-40 amatanthauza chiyani mu mafuta

Poyamba, gawo ili limatchedwa SAE (Society of Automotive Engineers ku United States).

Olemba oyamba mzere usanafike akuwonetsa momwe mafuta amakhalira nyengo yachisanu. Mwanjira ina, mamasukidwe akayendedwe a mafuta pamazizira otsika. Chizindikiro cha W chimangonena za nyengo yachisanu. Nambala mpaka kalata W ikuwonetsa kuti injini izitha kutembenuka mosavuta nthawi yachisanu, momwe mpope wamafuta umapopera mafuta kuti apake mafuta pamalo, komanso momwe zingakhalire zosavuta kuti oyambitsa ayambitse injini kuti iyambe komanso ngati batire ali ndi mphamvu zokwanira.

Kodi magawo a viscosity achisanu ndi otani?

• 0W - imagwira ntchito mu chisanu mpaka -35-30 madigiri. KUCHOKERA
• 5W - imagwira ntchito mu chisanu mpaka -30-25 madigiri. KUCHOKERA
• 10W - imagwira ntchito mu chisanu mpaka -25-20 madigiri. KUCHOKERA
• 15W - imagwira ntchito mu chisanu mpaka -20-15 madigiri. KUCHOKERA
• 20W - imagwira ntchito mu chisanu mpaka -15-10 madigiri. KUCHOKERA

Manambala achiwiri pambuyo pa dash ndiwo mafuta a injini yotentha. Kuchepetsa chiwerengerochi, mafuta ndi ocheperako, motsatana, kukwera, kumakulanso. Izi zachitika kuti kutentha ndi injini kutenthedwe mpaka madigiri 80-90, mafutawo samasandukanso madzi (amasiya kugwira ntchito ngati mafuta). Kodi magawo a viscosity a chilimwe ndi chiyani ndipo amafanana ndi kutentha kotani?

• 30 - imagwira ntchito yotentha mpaka madigiri 20-25. KUCHOKERA
• 40 - imagwira ntchito yotentha mpaka madigiri 35-40. KUCHOKERA
• 50 - imagwira ntchito yotentha mpaka madigiri 45-50. KUCHOKERA
• 60 - imagwira ntchito yotentha mpaka madigiri +50. Kuchokera pamwamba

Mwachitsanzo. Mafuta a 5w-30 ndi oyenera kutentha kotere: -30 mpaka +25 madigiri.

Kodi 5w30 ndi chiyani?

5w30 - mafuta a injini okhala ndi mamasukidwe otsika. W inu 5w30 imayimira "WINTER" ndipo chiwerengerocho chikuyimira kukhuthala kwa mafuta pa kutentha kwakukulu.

Nambala code system ya gulu Mafuta a injini adapangidwa ndi Society of Automotive Engineers pansi pa dzina lakuti "SAE". Amagawa mafuta molingana ndi mawonekedwe ake. Chifukwa kukhuthala kwa mafuta kumasiyanasiyana ndi kutentha, mafuta amitundu yambiri amateteza kutentha.

Nambala 5 mu 5w30 imafotokoza mamasukidwe akayendedwe a mafuta pa kutentha otsika. Ngati chiwerengerocho ndi chochepa, ndiye kuti mafuta adzakhala ochepa kwambiri, choncho zingathandize injini kuyenda bwino ngakhale kutentha kochepa.

Nambala 30 ikuwonetsa momwe mafuta amagwirira ntchito pa kutentha kwanthawi zonse. 

5w30 imadziwikanso ngati mafuta opangira zonse chifukwa m'mikhalidwe yonse, monga kutentha kapena kuzizira, ndi yopyapyala mokwanira kuti iyende pa kutentha kochepa komanso yopyapyala kuti iyende pa kutentha kwakukulu.

Mafutawa amagwiritsidwa ntchito kwambiri pamafuta onyamula anthu komanso injini za dizilo. Zimachokera ku viscosity yotsika ya 5 mpaka kukhuthala kwapamwamba kwa 30.

5w30 galimoto mafuta amasiyana ndi ena, kuti ali mamasukidwe akayendedwe asanu, kutanthauza kuti ndi madzi ochepa pa kutentha otsika kwambiri, ndi mamasukidwe akayendedwe makumi atatu, kutanthauza kuti wocheperako viscous pa kutentha. Ndiwo mafuta a injini omwe amagwiritsidwa ntchito kwambiri ndipo ndi oyenera kwambiri pamagalimoto amtundu uliwonse ndi injini.

Kodi 5w40 ndi chiyani?

5w40 ndi mafuta a injini omwe amathandizira injini kuyenda bwino ndikusuntha magawo kuti asatenthedwe chifukwa cha kukangana. 5w40 imasamutsa kutentha kuchokera kumayendedwe oyatsa ndikuthandizira kuti injini ikhale yoyera powotcha zinthu zomwe zili mkati ndikuteteza injini ku okosijeni.

Kutentha kwa kunja ndi mkati mwa injini yothamanga kumakhudza momwe mafuta a injini angachitire bwino.

Nambala pamaso pa W imasonyeza kulemera kapena mamasukidwe akayendedwe a injini mafuta. Kuchuluka kwa chiwerengerocho, kuwonjezereka kwakuyenda mu injini kudzakhala kokulirapo.

W amasonyeza kuzizira kapena nyengo yozizira. 5w40 ili ndi kukhuthala kochepa kwa 5 ndi kukhuthala kwapamwamba kwa 40.

izi mafuta otentha, yomwe ingagwiritsidwe ntchito m'galimoto yomwe ikuyendetsa mafuta a lead ndi opanda lead. Kukhuthala kwamafuta a 5w40 kumachokera ku 12,5 mpaka 16,3 mm2 / s. .

5w40 mafuta galimoto ali kukhuthala yozizira 5, kutanthauza kuti ndi wochepa viscous pa kutentha otsika kwambiri. The apamwamba mamasukidwe akayendedwe kalasi ndi 40, kutanthauza kuti viscous basi pa kutentha kwambiri.

Mafuta agalimoto awa makamaka aku Europe omwe ali ndi injini zamafuta ndi ma pickups a dizilo aku America.

Kusiyana kwakukulu pakati 5w30 ndi 5w40

1. Onse 5w30 ndi 5w40 ndi mafuta injini, koma viscosity osiyana.
2. 5w30 imayenda bwino pa injini chifukwa ndi yokhuthala. Kumbali ina, 5w40 siwonenepa kwambiri.
3. 5w30 imagwira ntchito bwino ndipo mosasamala kanthu za kutentha kwakukulu ndi kotsika, kumtunda ndi kutsika i.e. Kumbali inayi, 5w40 imagwira ntchito mosalakwitsa pa kutentha kochepa.
4. 5w30 ndi injini okwera mtengo, ndi 5w40 ndi wotsika mtengo galimoto mafuta.
5. 5w30 si paliponse, koma 5w40 ili.
6. 5w40 ili ndi mamasukidwe apamwamba kwambiri kuyelekeza ndi 5w30 ku.
7. 5w30 ali ndi kutsika mamasukidwe otsika mlingo wa asanu ndi apamwamba mamasukidwe akayendedwe mlingo wa makumi atatu. Kumbali inayi, 5w40 ili ndi mawonekedwe otsika akukhuthala komanso kukhuthala kwapamwamba kwa makumi anayi.

Kodi Viscosity Yabwino Ya Mafuta A injini ya 350Z & G35 ndi iti? (Nissan V6 3.5L) | AnthonyJ350

Kuphatikizidwa

Mwachidule, pali kusiyana kotani pakati pa 5w30 ndi 5w40 injini mafuta? Yankho lake ndi mamasukidwe akayendedwe awo, komanso osiyanasiyana kutentha ntchito.

Ndi mafuta ati omwe mungasankhe ngati matenthedwe onse ali oyenera m'chigawo chanu? Poterepa, ndibwino kutsatira zomwe wopanga injini yanu adapanga (wopanga aliyense ali ndi kulolerana kwake kwamafuta, kulolerana uku kumawonetsedwa pamakina amafuta aliwonse). Onani chithunzi.

Kusankhidwa kwamafuta pamtunda wapamwamba

Ngati injini yayenda kale makilomita mazana masauzande, ndibwino kugwiritsa ntchito mafuta owoneka bwino, i.e. perekani zokonda 5w40 kuposa 5w30, chifukwa chiyani? Pakapita ma mileage okwanira, kuyimitsidwa kwa injini kumawonjezera, zomwe zimaphatikizapo kuchepa kwa kupanikizika ndi zinthu zina zosafunikira. Mafuta ochulukirapo amakupatsani mwayi woti mudzaze mipata yambiri, ngakhale pang'ono, koma kusintha magwiridwe antchito a mota.

Mutha kukhala ndi chidwi, m'mbuyomu tidaganizira:

• Mafuta a injini ya Mobil Super 3000 5w-40
• Mafuta a injini ya Castrol Magnatec 5W 40
• Mafuta a Shell Helix 10w-40

Kanema pali kusiyana kotani pakati pa mafuta a injini 5w30 ndi 5w40
