5W40 inogara iri mafuta akakodzera here?

Mafuta einjini akaiswa chiratidzo 5W40 pamwe ndiyo inonyanya kusarudzwa mhando yemafuta einjini yemotokari dzinotakura vanhu. Asi izvi zvinorevei uye zvichagara zvichiratidza mafuta akanyanya kumota yedu?

Oiri ine mabasa mazhinji akakosha - cools kufamba zvikamu zveinjini, inoderedza kukakavara uye kupfeka kwekutyaira, zvisimbiso kufamba zvikamu uye kunyange kuchengeta injini yakachena uye inodzivirira kuora... Ichi ndicho chikonzero zvakakosha kushandisa mafuta anodzivirira injini zvakanyanya.

Iyo ipfupi nzira, iyo inonyanya kukosha mafuta

Basa reinjini rinotoenderana nebasa remafuta. Nekudaro, zvakakosha kuziva kuti injini inopera zvakanyanya kwete apo, semuenzaniso, mota iri kutyaira nekumhanya munzira huru, asi. paunotanga nekudzima... Saka, nzendo pfupi ndidzo dzakaomera injini.

Zvinogona kunge zvichishamisa, asi kana uchityaira mota kwezvinhambwe zvipfupi, unenge uchida mafuta ari nani pane kana uchityaira mazana emakiromita usingamisiki. Mafuta akanaka kuwedzera hupenyu hwezvimwe zvikamu zvejiniuye zvechokwadi - ichakubvumira kuti utange injini mumamiriro ekunze akaipisisa (somuenzaniso, muchando chakanyanya).

Iyo inopisa iyo, iyo yakaderera iyo viscosity.

Iyo huru parameter yemafuta ndeye viscosity yayo. Sezvo mafuta anopisa, viscosity yawo inoderera. Sezvo injini inotonhora, viscosity inowedzera.. Mune mamwe mazwi - pakupisa kwakanyanya, mafuta emafuta anove akaonda, uye patinongoerekana tawedzera throttle nejini inopisa, yakaderera rpm uye isina kukwana mafuta, injini inogona kurasikirwa nekudzivirirwa kwechinguva!

Zvisinei, pangavawo nechinetso mafuta akanyanya viscoussezvo inogona kusvika kune imwe neimwe injini zvikamu zvishoma nezvishoma.

0W yakanakira chando

Pano isu tinoda kubata nekuputsika negiredhi re viscosity. Iyo parameter ine tsamba W (kazhinji kubva ku0W kusvika 20W) inoratidza chando viscosity. Iyo diki iyo W parameter, inokwidza kupikisa kwechando..

0W oiri inomira kune yakanyanya kutonhora - injini inofanira kutangwa kunyange patembiricha pazasi -40 madhigirii Celsius. 20W mafuta anoita zvakanyanya pakudziya kwakadereraiyo inogona kudzivirira injini kubva pa -20 degrees.

Oiri inodziya injini

Asi handizvo zvese, nekuti yechipiri parameter yakakoshawo. Nhamba iri mushure metsamba W inoratidza mafuta viscosity kana injini ichidziya kune yakajairika tembiricha yekushanda (inenge 90-100 madhigirii Celsius).

Iyo inonyanya kufarirwa viscosity giredhi ndeye 5W40.. Mafuta akadaro munguva yechando anoita kuti zvikwanise kutanga injini pane tembiricha ye -35 madhigirii, uye kana ichidziya, inopa viscosity iyo yakakwana kune akawanda masimba masimba. Kune vazhinji - asi kwete kune vese!

Low viscosity mafuta

Mafuta e20 kana 30 mamakisi anonzi mafuta ekuchengetedza simba... Iyo yakaderera iyo viscosity, iyo yakadzika iyo mafuta kuramba, izvo zvinoreva kushoma kurasikirwa kwesimba reinjini. Zvisinei, pazvinopisa, zvinoumba zvakawanda firimu rakatetepa rinodzivirira.

Iyi yakaderera viscosity inobvumira mafuta kuyerera nekukurumidza pakati pezvikamu zveinjini, asi mune akawanda powertrains, kudzivirira uku hakuzove kwakakwana. Mumamiriro ezvinhu akadaro injini inogona kungojama.

Kazhinji mafuta emhando iyi anodururwa mumainjini emazuva ano - akapihwa, hongu, kuti mugadziri anokurudzira kushandisa mafuta eiyo viscosity.

High viscosity mafuta

Mafuta emagiredhi 50 ne60, pane zvinopesana, ane viscosity yakakwirira, saka, nenzira yekufananidzira, anoita se "akanyanya". Nekuda kweizvozvo, vanogadzira dhaka rakakora remafuta uye ivo vanodzivirira zviri nani mota kubva pakuremerwa... Kushandiswa kwemafuta akadaro kunogona kuve nekushomeka kwakashata pakushandiswa kwemafuta uye simba.

Mhando iyi yemafuta ndiyo inonyanya kushandiswa. mumainjini akasakara zvakaipa, zvakare mune avo "vanotora mafuta". Mafuta anonamira zvakanyanya anogona kuderedza kushandiswa kwemafuta uye kunyangwe, nekuda kwekuisa chisimbiso kwavo, kuderedza injini kutamiswa... Asi zvinoitikawo kuti high-viscosity mafuta ivo vanokurudzirwa kumotokari dzemitambokuchengetedza zvirinani madhiraivha ako akasimba uye nekudaro anodiwa.

Ndinofanira kuchinja viscosity here?

Kupindura mubvunzo wemusoro, Oiri 5W40 (kana 0W40) brand yakanaka (e.g. Castrol, Liqui Moly, Gumi nerimwe) ichava sarudzo yakanakisisa mumamiriro mazhinji.

Kutsiviwa kwepamusoro-viscosity yechando mafuta mumamiriro edu ekunze hapana chikonzero - zvinogona kutungamirira kumatambudziko nekutanga motokari munguva yechando. Kunze kwekuti tinoda mafuta ane viscosity yakakwirira yezhizha, uye mafuta akadaro ane viscosity, somuenzaniso, 10W60.

Mutsara shandura mafuta kune mafuta ane yakakwirira kana yakaderera viscosity yezhizha dzimwe nguva zvine musoro (somuenzaniso, ine injini yemitambo, yemazuva ano zvikuru kana, zvakasiyana, yekare), asi sarudzo inoitwa zvakanakisisa mushure mekuverenga bhuku remotokari uye kubvunza ane ruzivo makanika.
