Gear 75W90 uwoyela, 85W90, 80W90 futhi 75W140 - lokho ukukhetha?

Ukubeka lamafutha igiya 75W90 lemali into engavamile, ngokuvamile imoto abathanda uqiniseka ukuthi kuba eyamukelekayo izinga igrisi. Ungazama ukuya isinyathelo esisodwa okunye futhi ukhethe okusamanzi okungaphathwa azofanela futhi imodeli imoto, futhi imali awuzange sverhdorogoy.

amakilasi transmissionok

Gl iqembu basonta igrisi hypoid. Okusho ukuthi gcoba enama-asi ezingemuva futhi ukudluliswa ahlukene ezifuywayo Uphawu lezimoto ngokuthi "Lada", "Niva", "iVolga". Truck, yebo, kubuye kube efanelekayo, kodwa izindleko ibiza kakhulu.

I obujwayelekile igiya uwoyela 75W90 viscosity banga. Okukhishwayo kuhlanganisiwe amafutha brand "Castrol". umugqa Bahlanganisa Lubrication 85W90 futhi 80W90 uketshezi ngaphezulu. Ngaphezu kwalokho, eduze uvukile ngamafutha GL 5 igiya 75W90 75W140. Le nguqulo yakamuva viscosity asifanele kakhulu izimoto Russian. Ivame wathela kwi ezingemuva-ezidonsa izinguqulo, kanye onobuhle umehluko lockable. Ziyakwazi Cishe ukuba ngikhonze njengephayona elihle 'ukuqapha "noma" Land Cruiser "futhi ekhaya kuyoba obukhulu khulu. Gcwalisa nabo kumodi evamile wokusebenza akwenzi mqondo. Kodwa uma enama-asi engemuva "ukucula", bathi uketshezi lubricating enjalo angase afanelekele ngaleso sikhathi.

Nokho, uma 'mineral water' engabizi ubhekana imisebenzi yawo, kungani bachithe imali ethe xaxa kwi zokwenziwa?

amafutha Gear of viscosity ezahlukene

Phakathi motor amafutha ngokuphelele yokufakelwa zokwenziwa base eside iwine ukuthandwa enkulu. Bona Kwasakazwa namafutha igiya 75W90, 85W90, 75W140. Iningi lubricating uketshezi esekelwe zokwenziwa ingasetshenziswa unyaka wonke. Ngisho ngesikhathi aphansi kakhulu lokushisa ukusebenza uyonikwa imiphumela emihle sokusebenza. Ngokwesibonelo, uma uqhathanisa 85W90 amaminerali amanzi lokususa nambili degrees c zokwenziwa 75W140 emakhazeni at degrees amane, imiphumela viscosity kuyoba cishe izakhamuzi zaseBosnia zifana. Futhi uma ibekwe endaweni umbuso lokushisa ukuze -20 degrees, umphumela kungaba ezahlukene ezikhathini 30-50. Lona ube nesisekelo esiqinile kakhulu. It kuvela ukuthi kwelinye icala injini ngeke neze, kanti kwesinye - Cishe kufana Ngezikhathi zasehlobo.

Indawo yezihlanganisi uketshezi ukuhlolwa

Izinzuzo kuzoveza nakakhulu uma bezama usebenze ngaphansi kwezimo ezimbi. Lapho imithwalo esindayo lubricating uketshezi babe uketshezi ngaphezulu. Ngakho-ke, ukuhlolwa ezifanele Kwakuseshwa. Yiqiniso, kwakulindeleke ukuba labo babe nekhwalithi ephezulu, lapha ngeke baziphathe kangcono futhi ubonise imiphumela uhambisane kakhulu. Nakhu okwenzeka.

Umphumela uzobe ngokucace kakhudlwana kubonakala izibalo. Welding umthwalo esiku 4-ball ngomshikisho umshini ikhomba ikhono ukugcina umthwalo esibucayi. Amafutha kuwo zihlukaniswe amaqembu. Ngakho, GL 3 inenani ubuncane 2760N, igiya uwoyela 75W90 - GL 4 - 3.000 N futhi GL 5 - 3280N.

Imiphumela ukuhlolwa

Futhi imiphumela yokuhlolwa zazimi kanje. Eshibhe Amafutha 85W90 viscosity ukusuka 2607 kuya 4635N. Imidiyeni kubo - 3827N. Kunengqondo ukuphetha ngokuthi lidlula ngisho GL 5. Kodwa bheka phambili. "AvtoVAZ" iyadingeka transmissionka ne Inkomba ngenhla 3483N futhi AZLK - 3924N. umphumela ayisabhekwa njengoba omuhle ukuhambisana nezimfuneko enjalo.

Okunye uwoyela test waba viscosity 80W90. Inani layo isilinganiso unikezwa isibalo 4122N, okuyinto vele ngcono kakhulu. Imiphumela nakakhulu ziboniswa igiya 75W90 uwoyela. Lapha, amagugu zazisuka 3685 kuya 5204N futhi 4508N isilinganiso kulokho Yiqiniso, uyajabula.

Kuba nemiphumela emihle kakhulu, yebo, banikwa viscosity 75W140. Nokho, ezinjalo transmissionka neze ezidingekayo ukuze wonke umuntu.

Ngakho onjani uwoyela ukugcwalisa?

Kafushane, singaphetha ngokuthi uma imoto okufanele isebenze at okushisa ngezansi -12 degrees, kungenzeka ukuphatha uwoyela viscosity ekilasini 85W90. Kuyinto inketho engabizi kakhulu, futhi production ezifuywayo izobiza ngempela ezishibhile.

Uma izinga lokushisa uwela endaweni kuze kube 26 degrees Celsius, kubalulekile ukuthola uwoyela 80W90. Nayo imoto uyozizwa uqiniseka ngokwengeziwe okwamanje.

Nokho, igiya 75W90 uwoyela, ukubuyekezwa zazo zingatholakala kunethiwekhi ngokuvamile kakhulu, ngisho nangokwengeziwe 75W140 viscosity grade, kakade kubalandeli ukushayela kakhulu. Yiqiniso, intengo yayo kuyoba ephakeme.

Bala lemali edingekayo (isibonelo, kwi "Lada" - engemuva oluvala amasondo kuthatha cishe ezintathu amalitha) futhi ifaniswe mileage (on the brand efanayo idinga ukushintshwa njalo 60 000 km), njalo umshayeli ungakwazi ukubala malini we imali kuyoyilahlekisela elilodwa noma kwenye uwoyela futhi isekelwe la idatha ukwenza ukukhetha.

Uma sikhuluma brand ethize eziwuketshezi igiya lubricating, kungenzeka ukuba uqaphele amafutha ambalwa angaphandle, kubonise imiphumela emihle:

• Wellrun yabonisa irekhodi Welding umthwalo.
• Liqui Moli - yerekhodi ngokuphelele ngenxa ukumelana ezibandayo.
• Castrol 75W140 - kube nomphumela omuhle kakhulu we ukumelana okweqile.
• Spectrol Synax (brand ezifuywayo) abided yibo bonke amazinga, kodwa azifinyelelanga izimfuno ngokweqile.
