Amafutha M8DM. Izimpawu nabakhiqizi

Технические характеристики

Ngokwezinga elijwayelekile le-GOST 17479.1-2015, uwoyela we-M8Dm ubhekisela kumafutha wezinjini zikaphethiloli nezinjini zikadizili. Cabangela izici eziyinhloko zala mafutha.

1. Isisekelo. Njengesisekelo samafutha enjini ye-M8Dm, kusetshenziswa isisekelo samaminerali ahlanzekile, athuthukiswe kusuka kumazinga aphansi anesulfure yamafutha.
2. Izithasiselo. Iphakheji elengeziwe lijwayelekile kuzinto zokugcoba zaleli zinga. I-calcium yayisetshenziswa njenge-disperant. Ukuze kuthuthukiswe ingcindezi eyedlulele kanye nezimfanelo ezingagugi ze-lubricant, zinc ne-phosphorus zisetshenziswa ngenani elincane.
3. i-kinematic viscosity. Ku-100°C, i-viscosity yamafutha okukhulunywa ngayo kufanele ibe phakathi kuka-9,3 no-11,5 cSt, okuyi-SAE 20 yi-American Society of Automotive Engineers.
4. Okuqukethwe kwesibabule. Amafutha abhekisela ku-low-sulphur, njengoba kuboniswa inkomba ethi "m" esihlokweni. Okusho ukuthi, idiphozithi ye-sludge uma isetshenziswa ngisho nasezinjini ezithambekele kule nqubo izoba yincane.

5. Inombolo ye-alkaline. Lesi sibalo singahluka kuye ngomkhiqizi. Kodwa ngokuvamile inombolo ye-alkaline yamafutha e-M8Dm iphakathi kuka-8 mgKOH / g. Cishe izinkomba ezifanayo zamafutha e-M8G2k.
6. Iphoyinti le-Flash. Ngokwesilinganiso, uwoyela uyavutha uma ushiswa ku-crucible evulekile lapho ufinyelela ku-200 ° C. Futhi, okuningi kuncike kumkhiqizi. Isimo esifanayo sibonwa emafutheni asekhaya we-M10G2k, lapho iphuzu langempela le-flash lingahluka ngo-15-20 ° C, kuye ngokuthi ubani owenze i-lubricant.
7. Izinga lokushisa elibandayo. Njengomthetho, ku-low-viscosity grease, indawo yokuthela iphakeme kakhulu. Uwoyela we-M8Dm wawunjalo: indawo yokuthela emaphakathi isendaweni -30 ° C.

Izinga alikhawuleli izinkomba eziningi manje ezithathwa njengezibalulekile kuwoyela wezimoto. Futhi le mingcele ingahluka kakhulu kuye ngokuthi ubani umenzi kawoyela.

Izicelo

Esigabeni esijwayelekile se-GOST, ububanzi buthonywa kakhulu yiqembu lapho uwoyela wenjini ungowalo. Endabeni yomkhiqizo okukhulunywa ngawo, i-M8Dm, isigaba sikawoyela "D" sibonisa lokhu okulandelayo:

• amafutha angasetshenziswa ezinjini zikaphethiloli eziphoqelelwe nge-carburetor noma umjovo owodwa, kodwa ngaphandle kwe-catalyst noma umjovo osakazwayo;
• uwoyela okukhulunywa ngawo ubuye afanelekele izinjini zedizili ezisheshisa kakhulu ezine-turbine kanye ne-intercooler, kodwa ngaphandle kwesihlungi sezinhlayiya, esisebenza ezimeni ezinzima kakhulu kunama-lubricant eqembu G.

Eqinisweni, indawo eyinhloko yokusetshenziswa kwalo mafutha ngamaloli okulahla asindayo, imishini yezimayini, ogandaganda namaloli anezinjini zikadizili. Kancane kancane, uwoyela usetshenziswa emalolini amancane okuhweba anezinjini zikaphethiloli. Ezifundeni eziseningizimu, kusetshenziswa i-analogue ewugqinsi yala mafutha: M10Dm.

Izinga lombuso liphinde lidwebe isifaniso nokuhlukaniswa kwe-API. Amafutha okukhulunywa ngawo ahambisana nekilasi le-CD / SF. Leli izinga eliphansi, futhi emazweni aseNtshonalanga izithambisi zaleli zinga sezithathwa njengezingasasebenzi futhi azikhiqizwa.

Abakhiqizi namanani

Amafutha enjini ye-M8Dm akhiqizwa yizindawo ezimbalwa zokuhluza uwoyela zasekhaya.

1. Lukoil M8Dm. Ithengiswa kakhulu ngamathini angu-18 wamalitha. Intengo ejwayelekile ilitha ngayinye ingama-ruble angama-90-100. Umphongolo 205 amalitha izobiza ruble mayelana 90-95 ilitha.
2. I-Gazpromneft M8Dm. Kubiza kancane, ngokwesilinganiso ruble 105-115 ilitha. Umthamo ojwayelekile ungamalitha ayi-18. Amathini anomthamo omncane ngokwenani ilitha ngalinye azobiza ngaphezulu.
3. I-Naftan M8Dm. Inketho eshibhile. Intengo elinganisiwe - ama-ruble angama-85-90 ilitha ngalinye.
4. I-Oilright M8Dm. Ibiza cishe ngokufana namafutha avela eNaftan. Nokho, ngokwesilinganiso, uma sicabangela abathengisi abambalwa, i-Oilright M8Dm ibiza kancane. Ungathola i-canister engamalitha angu-20 ngama-ruble angu-1600-1700. Okusho ukuthi, ama-ruble angama-80-85 ilitha ngalinye.

Izibuyekezo ezimayelana nowoyela wenjini ye-M8Dm ezikhathini eziningi azinawo uhlangothi. Kodwa, uma sicabangela ukuphawula kwabanikazi bemishini abagcwalise la mafutha, kufanele asetshenziselwe injongo ehlosiwe futhi kuhle ukuyishintsha kaningi kunalokho okudingwa yimithethonqubo.

Umkhonyovu kawoyela wezimoto. Iqiniso mayelana namafutha e-Ch5
