Injini yemafuta viscosity giredhi - chii chinosarudza uye kuti ungaverenga sei kumaka?

Uri kutsvaga mafuta einjini, asi kunyora pane zvakatemwa zvezvakagadzirwa hazvireve chinhu kwauri? Tauya kuzonunura! Muchinyorwa chanhasi, tinotsanangura makodhi akaomarara anoonekwa pamafuta einjini mavara uye tinotsanangura zvekutarisa kana uchisarudza lubricant.

Kupfupi kutaura

Viscosity ndiyo nzira iyo mafuta anopfuura nyore nyore kuburikidza nejini pane imwe tembiricha. Inotaridzirwa neSAE classification, iyo inoparadzanisa mafuta muzvikamu zviviri: nguva yechando (inoratidzwa nenhamba uye tsamba W) uye yakakwirira-yekushisa (inoratidzwa nenhamba), iyo inoratidza kutonhora kwakagadzirwa nedhiraivha yekushanda.

SAE mafuta viscosity classification

Isu tinogara tichisimbisa kuti nhanho yekutanga pakusarudza iyo injini mafuta inofanirwa kuve yakasimbiswa. kurudziro yemugadziri wemotokari... Iwe unozviwana mubhuku rekuraira remotokari yako. Kana iwe usina imwe, iwe unogona kushandisa online yekutsvaga injini iyo ichakubatsira iwe kusarudza mafuta nemotokari kugadzira uye modhi, pamwe neiyo injini paramita.

Imwe yeanonyanya kukosha maitiro emafuta, anotsanangurwa zvakadzama mubhuku rekuraira remota, ndeye viscosity. Inoona kuti oiri inoyerera sei nyore nyore kuburikidza nejini pane imwe tembiricha.zvose nemukati, zvakaumbwa panguva yekushanda kwayo, uye nekushisa kwemukati. Ichi chinhu chakakosha parameter. Yakanyatsosarudzwa viscosity inovimbisa-isina dambudziko kutanga pazuva rechando, kukurumidza kugoverwa kwemafuta kune ese madhiraivha edhiraivha uye kuchengetedza iyo chaiyo firimu remafuta rinodzivirira injini kubva pakubatwa.

Iyo viscosity yemafuta einjini inotsanangurwa nekupatsanurwa Association of Automotive Engineers (SAE)... Mune iyi chiyero, mafuta anokamurwa kuita winter (inoratidzwa nenhamba uye tsamba "W" - kubva "muchando": 0W, 5W, 10W, 15W, 20W, 25W) uye "zhizha" (inotsanangurwa chete nenhamba: SAE 20, 30, 40, 50, 60). Zvakadaro, izwi rekuti "zhizha" pano rinorerutsa. Iyo yechando gradation inonyatsoratidza mafuta anogona kushandiswa munguva yechando apo thermometer inodonha zvakanyanya. "Zhizha" kirasi inotemerwa zvichibva pane zvishoma uye yakanyanya lubricant viscosity pa100 ° C, uye zvishoma viscosity pa 150 ° C - ndiko kuti, panguva injini kushanda tembiricha.

Parizvino, isu hatisisiri kushandisa zvigadzirwa zvepachena zvakachinjirwa kumwaka. Muzvitoro, iwe unowana chete akawanda-giredhi oiri akasarudzwa nekodhi ine nhamba mbiri uye tsamba "W", semuenzaniso 0W-40, 10W-40. Inorava seizvi:

• iyo diki nhamba iri pamberi pe "W", mafuta mashoma achabata high fluidity pane subzero tembiricha -inosvika ese ejini zvikamu nekukurumidza;
• iyo yakakura nhamba mushure me "W", mafuta akawanda anochengetwa. yakakwirira viscosity pakupisa kwakanyanya kunogadzirwa neinjini inomhanya - zviri nani inodzivirira madhiraivha akaiswa kumitoro yakakwira, sezvo inoapfekedza neyakakora uye yakagadzikana firimu remafuta.

Mhando dzemafuta einjini ne viscosity

0W-16, 0W-20, 0W-30, 0W-40

0W kirasi oiri inobuda pachena kupfuura vakwikwidzi vavo maererano nekuchengetedza viscosity pane yakaderera tembiricha - chengetedza injini yakanaka kutanga kunyangwe -35 ° C... Iwo akagadzikana nemafuta uye anoshingirira kune oxidation, uye nekuda kwehunyanzvi hwekugadzira tekinoroji, anogona kuderedza kushandiswa kwemafuta. Pakati pemafuta ekirasi iyi, inonyanya kufarirwa ndeye 0W-20 oiri, iyo inoshandiswa neHonda kunetseka seyainzi yekutanga fekitori mafashamo, uye zvakare yakatsaurirwa kune dzimwe dzakawanda dzemazuva ano mota dzeJapan. 0W-40 ndiyo inonyanya kushandiswa - yakakodzera kumotokari dzose dzine vagadziri vanobvumira kushandiswa kwemafuta 0W-20, 0W-30, 5W-30, 5W-40 uye 10W-40. Izvi zvitsva Oiri 0W-16 - yakaonekwa pamusika nguva pfupi yadarika, asi yakatoongororwa nevagadziri veJapan. Inoshandiswawo mumotokari dzakasanganiswa.

5W-30, 5W-40, 5W-50

Mafuta einjini kubva kuboka re5W ane zvishoma zvishoma viscous - Iva nechokwadi chekuti injini yakatsetseka inotanga pakudziya kusvika -30 ° C... Vatyairi vainyanya kufarira mhando 5W-30 uye 5W-40... Ose ari maviri anoshanda zvakanaka mukutonhora kwechando, asi iyo yekupedzisira yakati tsindi, saka ichashanda zvirinani pamotokari dzakura, dzakasakara. Injini dzinoda firimu remafuta rakagadzikana dzinowanzo shandisa oiri ine kunyange yakakwirira-yepamusoro-tembiricha viscosities: 5W-50.

10W-30, 10-W40, 10W-50, 10W-60

10W mafuta anoramba ari viscous pa -25 ° Csaka vanogona kushandiswa zvakachengeteka mumamiriro ekunze edu. Vanonyanya kufarirwa ndivo 10W-30 uye 10W-40 - anoshandiswa mumotokari zhinji mumigwagwa yeEurope. Ose ari maviri anogona kutsungirira mitoro yakakwira yekupisa uye kubatsira kuchengetedza injini yakachena uye iri mumamiriro akanaka. Mafuta 10W-50 uye 10W-60 Iwo anoshandiswa mumotokari dzinoda kuchengetedzwa kwakawanda: turbocharged, mitambo uye vintage.

15W-40, 15W-50, 15W-60

Kune mota dzine yakakwira mileage, mafuta einjini ekirasi 15W-40 uye 15W-50iyo inobatsira kuchengetedza yakanyanya kudzvanywa mu lubrication system uye kuderedza kuvuza. Zvigadzirwa zvakamaka 15W-60 zvisinei, dzinoshandiswa mumhando dzekare uye motokari dzemitambo. Mafuta ekirasi iyi bvumira mota kuti itange pa -20 ° C.

20W-50, 20W-60

Mafuta emota ekirasi iyi anoratidzirwa neiyo yakaderera viscosity pane yakaderera tembiricha. 20W-50 uye 20W-60... Mazuva ano, haawanzoshandiswa, chete mumotokari dzekare dzakavakwa pakati pe50s ne80s.

Viscosity chinhu chakakosha parameter yechero lubricant. Paunenge uchisarudza mafuta, nyatsotevera kurudziro yemugadziri wemota yako - chigadzirwa chawakasarudza chinofanira "kuenderana" nehurongwa: tamba pakati pezvinhu zvega kana kudzvanywa mairi. Uyewo yeuka kuti munyaya iyi kuchengetedza kunongoonekwa chete. Panzvimbo pemafuta akachipa asina zita kubva pamusika, sarudza inozivikanwa brand chigadzirwa: Castrol, Elf, Mobil kana Motul. Iyo chete lubricant ichapa injini mamiriro ekushanda akakwana. Unogona kuzviwana pa avtotachki.com.
