Chii chinonzi mafuta einjini yemotokari yemitambo?

Mota dzemitambo dzinosiyana nemotokari dzevafambi mukugadzira uye kushandiswa. Injini dzavo dzinoshanda pasi pemamiriro ezvinhu akaoma, ndicho chikonzero vanoshandisa mafuta ane zvakakosha. Vanofanira kumira tembiricha yakakwira uye zvinobudirira kuzadza injini zvikamu. Muchinyorwa chemazuva ano, iwe uchadzidza nzira yekusarudza mafuta emotokari yemitambo.

Chii chauchadzidza kubva pane ino post?

• Chii chinogadza viscosity giredhi yemafuta einjini?
• Ndeipi viscosity inofanira kunge iri mafuta emotokari yemitambo?
• Ndezvipi zvimiro zvinofanira kuva nemafuta emotokari yemitambo?

Kupfupi kutaura

Motokari zhinji dzemitambo dzinoishandisa high viscosity mafutaizvo zvinogadzira firimu rakasimba rinodzivirira zvikamu zvejini kunyange pasi pemamiriro ezvinhu akaoma. Zvimwe zvakakosha kudonha kwemhepo, shear resistance uye kubviswa kwemakemikari kubva mumafuta asina kupiswa kuti injini igare yakachena.

Iyo inonyanya kukosha parameter ndeye viscosity kirasi.

Viscosity kirasi inonyanya kukosha parameter yemafuta einjini.uyo inosarudza kureruka kwekuyerera kwemafuta pane imwe tembirichauye saka tembiricha iyo inogona kushandiswa. Iyo yakaderera kukosha, iyo yakaonda mafuta, asi zvakare inoreva yakaonda firimu layer inodzivirira zvikamu zveinjini panguva yekushanda. Mumotokari dzakajairwa, mayuniti emagetsi anochinjirwa kune yakaderera-viscosity oiri, iyo inoderedza hydraulic kuramba uye inoderedza kushandiswa kwemafuta uye kubuda kwezvinhu zvinokuvadza. Zvakadini nemotokari dzemitambo?

Injini yemafuta viscosity giredhi

Injini dzeFormula 1 mota dzinoisa simba pamusoro pekugara. Ivo vanoshandisa yakaderera viscosity oiri izvo zvinoderedza kudhonza panguva yekushanda asi kupfupisa injini hupenyu. Nekudaro, izvo zvinodikanwa zvemafuta emotokari zhinji dzemitambo zvakati siyanei. Mota dzawo hadzina kuchengetedzwa zvakanaka nekuti dzinoshanda patembiricha yakakwira uye zvikamu zvadzo zvinowedzera kuwedzera kwemafuta. Mafuta anoshandiswa mavari anofanira kunge ane viscous zvakanyanya, kunyanya pakupisa kwakanyanya. - injini inogara yakanyatsogadzirirwa uye inodziya isati yasimuka. Kazhinji ivo mafuta ane viscosity kirasi ye10W-60 uye yakakwirira... Vanogadzira zvinogara oiri sefa inodzivirira injini zvikamu kunyange pasi pemamiriro akanyanya uye inopa chisimbiso chakarurama chezvinhu zvayo zvose, semuenzaniso, pistons, iyo, kana inopisa, inowedzera hukuru hwavo, saka kukodzera kwavo mu cylinder liner inova yakasimba kwazvo.

Zvimwe zvinhu zvemafuta

Pakusarudza mafuta, kuwedzera kune viscosity giredhi, kunaka kwayo kwakakoshawoSaka zvakakodzera kuvimba nezvigadzirwa zvevanozivikanwa vanogadzira. Motokari dzemitambo dzinoshandisa mafuta ekugadzira anobva pamafuta anokoshaiyo ine yakakwirira paramita pane yakajairwa PAO-based oiri. Ivo vanopfumiswa neakakodzera ekuwedzera anokanganisa maitiro emafuta. Chinonyanya kukosha kwavari - yakaderera evaporation, kumanikidza uye shear kuramba uye kubviswa kwemakomisheni kubva kumafuta asina kupiswa... Kuvonga kwavari, mafuta haachinje maitiro ayo kunyange pakupisa kwakanyanya uye anobatsira kuchengetedza injini yakachena.

Inokurudzirwa mafuta emotokari dzemitambo:

Yakakurudzirwa mafuta emotokari dzemitambo

Paunenge uchitsvaga mafuta emotokari yemitambo, hapana nzvimbo yekukanganisa, saka zvakakodzera kutendeukira kune zvigadzirwa zvevanozivikanwa vanogadzira. Iri boka rinosanganisira Castrol Edge 10W-60, iyo yakanakira tembiricha yepamusoro uye inorema basa rekushandisa. Chimwe chigadzirwa chinokurudzirwa mugadziri weGerman Liqui Moly Race Tech GT1 oiri, iyo inonyatso gadzira iyo magetsi unit mumamiriro akanyanya uye tembiricha. Izvo zvakakoshawo kufunga kutenga Shell Helix Ultra Mujaho mafuta, iyo yakagadziridzwa mukubatana neFerrari nyanzvi. Zvese zviri pamusoro pezvigadzirwa zvine viscosity level ye10W-60.
