Gear mafuta 75W90, 85W90, 80W90 uye 75W140 - chii kusarudza?

Kuisa pamusoro giya mafuta 75W90 sawanikwa mari, yemanyorero motokari iyi vanoda chokwadi kuti zvinogamuchirika yepamusoro mafuta. Unogona kuedza kuenda rimwe danho uye kusarudza mvura kuti zvaizoita kukodzera uye motokari womuenzaniso, uye mari haana sverhdorogoy.

GL boka kuva hypoid mafuta. Ndiko, ivo girisi veshure zvokubatisa uye vakaparadzana hutachiwana mudzimba motokari pezvitsiga se "vakanciq", "niva", "Volga". Truck Chokwadi, zviri zvakare rakakodzera, asi mari ndiyo zvinodhura.

Rakajairika ndiye ari giya mafuta 75W90 viscosity kugiredhi. The anosiyiwa zvaisanganisira mafuta muchiso "Castrol". mutsetse yavo inosanganisira lubrication 85W90 uye 80W90 mamwe mvura. Uyezve, pedyo wamuka pamwe GL 5 giya mafuta 75W90 75W140. Izvi matsva shanduro viscosity hakusi akakodzera chaizvo nokuti mota Russian. Zvinonzi Kazhinji chadururirwa necheseri-vhiri-nemotokari shanduro, uyewo yokutevedzera pamwe lockable differential. Vanowanzova ave kwazvo "patrol" kana "Nyika ngarawa" uye kumusha uchakomborerwawo gobvu. Zadza navo chakaipa nokushanda kwadzinoita hazvina musoro. Asi kana zveshure zvokubatisa "nziyo", ivo yakadai lubricating Urume kungava dzakakodzera panguva.

Zvisinei, kana munhu chicherwa mvura chipa kuzvigona mabasa ayo, nei kupedza imwe mari pamusoro muzvinhu zvinogadzirwa nemakemikari?

Gear anonhuwirira dzakasiyana viscosity

Pakati injini mafuta zvachose chakagadzirwa chakaita zvokugadzirwa chawo refu ahwina kukurumbira mukurusa. Vakanga akagoverwa uye giya mafuta 75W90, 85W90, 75W140. Ruzhinji lubricating zvinwiwa kwakavakirwa chakaita zvokugadzirwa zvingashandiswa gore rose. Kunyange panguva yakaderera chaizvo tembiricha waivako vachakupai zvakanaka dzichipfekeka zvabuda. Somuenzaniso, kana iwe enzanisa 85W90 chicherwa mvura panguva kubvisa gumi madhigirii C muzvinhu zvinogadzirwa nemakemikari 75W140 muchando pa makumi mana madhigirii, kuti viscosity zvabuda achava husingakuvadzi indistinguishable. Uye kana vari Vakaisa tembiricha hurumende kusvika -20 madhigirii, mugumisiro zvaizova zvakasiyana 30-50 nguva. Iyi nheyo yakasimba chaizvo. Zvakaratidza kuti mune imwe nyaya injini kashoma, uye mune imwe - dzinenge akafanana ari inodziya mwedzi.

Lubricating zvinwiwa miedzo

Advantages zvicharatidza zvakatowanda kana vanoedza kushanda mumamiriro ezvinhu akanyanyisa. Kana inorema lubricating Urume huchawedzera zvokunwa. Naizvozvo, miedzo yakakodzera rwaiitwa. Ichokwadi aitarisirwa kuti vaya vane yepamusoro quality, pano achazvikudza nani uye kuratidza kupfuura kupindirana zvabuda. Izvi ndizvo zvakaitika.

Mugumisiro aona zvichange zvakawanda pachena nenhamba. Welding mutoro uri kwakajairika 4-ball kukweshera muchina rinozivisa kugona kuchengeta dzinonetsa mutoro. Mafuta pachiri akakamurwa muzvikwata. Saka, GL 3 ane risingamboshandisi kukosha 2760N, giya mafuta 75W90 - GL 4 - 3,000 N uye GL 5 - 3280N.

Results miedzo

Zvino pakuongororwa vaiva sezvinotevera. Yakachipa pashiri Oil 85W90 viscosity akanga kubva 2607 kusvika 4635N. The evaMedhia navo - 3827N. Zvaizoratidza sokuti kwazvo kunyange GL 5. Asi kutarira mberi. "AvtoVAZ" kunodiwa transmissionka pamwe indekisi pamusoro 3483N uye AZLK - 3924N. mugumisiro hakuchisina kuonekwa sezvo yakanaka pokuita nezvinodiwa akadaro.

Mamwe bvunzo mafuta aiva viscosity pamusoro 80W90. avhareji kukosha kwayo akapiwa uwandu 4122N, riri kare nani zvikuru. Kunyange nani zvabuda vanoonekwa giya mafuta 75W90. Pano, tsika ranged kubva 3685 kusvika 5204N uye 4508N paavhareji yakapiwa kuti Chokwadi, akafara.

Migumisiro yakanakisisa, Chokwadi, vakapiwa viscosity 75W140. Zvisinei, izvozvo transmissionka asiri zvakakodzera kuti munhu wose.

Saka worudzii mafuta kuzadza?

Mukupfupikisa, tinogona kugumisa kuti kana motokari zvinofanirwa anoshanda kutonhora pazasi -12 madhigirii, zvinokwanisika kuti kushandisa mafuta viscosity kirasi 85W90. Ndicho zvikuru chipa chisarudzo, uye mudzimba kugadzirwa achaita mari zvikuru chisingakoshi.

Kana tembiricha inowira munzvimbo kusvika 26 Celsius, zvinokosha kuwana mafuta 80W90. Nawo motokari uchawedzera kuva nechivimbo panguva ino.

Eya, giya mafuta 75W90, wongororo izvo zvinogona kuwanika pamusoro pomumbure kakawanda, uye kunyange zvakawanda 75W140 viscosity giredhi, atova nokuda mafeni zvokuora kutyaira. Chokwadi, mutengo wawo achava kwirirei.

Ngaaverenge inodiwa mari (somuenzaniso, pamusoro "vakanciq" - Rear ekisero zvinotora inenge mitatu litres) uye akafanana kuti mileage (musi iwoyo muchiso anofanira kutsiviwa ose 60 000 km), muchairi ose anogona ngaaverenge sei zvakawanda mari mari iye mumwe kana mumwe mafuta uye kwakavakirwa mashoko aya kuti sarudzo.

Kana isu kutaura dzakananga mavanga giya lubricating zvinwiwa, zvinokwanisika kuona zvishoma yokumwe mafuta, vakaratidza migumisiro yakanaka:

• Wellrun akaratidza rekodhi Welding mutoro.
• Liqui Moli - zvinyorwa kwakakwana kuti kuramba inotonhora.
• Castrol 75W140 - yakanakisisa pamusana kuramba overheating.
• Spectrol Synax (mudzimba pezvitsiga) nokugarwa nezvinodiwa zvose, asi haana asvika kunyanyisa wandei.
