Ingabe i-5W40 ihlale ingamafutha afaneleka kakhulu?

Amafutha enjini amakwe ngophawu 5W40 mhlawumbe uhlobo oluvame ukukhethwa lwamafutha enjini ezimotweni zabagibeli. Kodwa sisho ukuthini lesi sifinyezo futhi ingabe izohlale ikhombisa uwoyela ongcono kakhulu wemoto yethu?

Uwoyela unemisebenzi eminingi ebalulekile - kuyaphola izingxenye ezihambayo zenjini, kunciphisa ukungqubuzana nokugqoka ukushayela, izimpawu izingxenye ezihambayo futhi igcina injini ihlanzekile futhi kuvimbela ukugqwala... Yingakho kubaluleke kakhulu ukusebenzisa amafutha ayivikela kangcono injini.

Lapho imizila imifushane, uwoyela ubaluleke kakhulu

Umsebenzi wenjini uhlotshaniswa nomsebenzi kawoyela. Kodwa-ke, kufanelekile ukwazi ukuthi injini iguga kakhulu hhayi lapho, isibonelo, imoto ishayela ngesivinini esikhulu emgwaqeni omkhulu, kodwa lapho uqala futhi ucisha... Ngakho, uhambo olufushane lunzima kakhulu enjinini.

Kungase kumangaze, kodwa uma uhamba ngemoto amabanga amafushane, uzodinga uwoyela ongcono kunalapho uhamba amakhulu amakhilomitha ungami. I-oiler enhle andise impilo yezingxenye zenjini ngayinyefuthi-ke - kuzokuvumela ukuthi uqale injini ezimweni ezimbi kakhulu zezulu (isibonelo, kuqhwa obunzima).

Lapho kushisa kakhulu, i-viscosity iphansi.

Ipharamitha eyinhloko yamafutha yi-viscosity yayo. Njengoba amafutha eshisa, i-viscosity yawo iyancipha. Njengoba injini iphola, i-viscosity iyanda.. Ngamanye amazwi - emazingeni okushisa aphezulu, ungqimba lwamafutha luba mncane, futhi lapho sifaka ngokuzumayo i-throttle ngenjini eshisayo, i-rpm ephansi namafutha anganele, injini ingalahlekelwa ukuvikelwa okwesikhashana!

Nokho, kungase kube nenkinga amafutha ane-viscous kakhulunjengoba ingase ifinyelele izingxenye zenjini ngayinye kancane kakhulu.

I-0W ilungele isithwathwa

Lapha sidinga ukubhekana nokuqhekeka ngebanga le-viscosity. Ipharamitha enohlamvu W (imvamisa isuka ku-0W iye ku-20W) ikhombisa i-viscosity yasebusika. Ipharamitha engu-W encane, iphakamisa ukumelana nesithwathwa..

Amafutha angu-0W azomelana nesithwathwa kakhulu - injini kufanele iqalwe ngisho namazinga okushisa angaphansi -40 degrees Celsius. Amafutha angu-20W enza okubi kakhulu emazingeni okushisa aphansiokungavimbela injini ukuthi iqale ku -20 degrees.

Amafutha enjini afudumele

Kodwa akugcini lapho, ngoba ipharamitha yesibili nayo ibalulekile. Inombolo engemuva kohlamvu W ekhombisa uwoyela viscosity lapho injini ifudumele ekushiseni okujwayelekile kokusebenza (cishe ama-90-100 degrees Celsius).

Ibanga elidume kakhulu le-viscosity yi-5W40.. Amafutha anjalo ebusika enza kube nokwenzeka ukuqala injini ekushiseni kwama-degrees -35, futhi lapho ifudumala, inikeza i-viscosity efanelekile kumayunithi amaningi wamandla. Kwabaningi - kodwa hhayi kubo bonke!

Amafutha e-viscosity aphansi

Amafutha amabanga angama-20 noma angama-30 abizwa amafutha okonga amandla... Uma i-viscosity iphansi, iyancipha ukumelana nowoyela, okusho ukuncipha kancane kwamandla enjini. Nokho, lapho kushisa, zakha eziningi ifilimu eliyisivikelo elincanyana.

Le viscosity ephansi ivumela uwoyela ukuthi ugeleze ngokushesha okukhulu phakathi kwezingxenye zenjini, kodwa kuma-powertrains amaningi, lokhu kuvikela ngeke kwanele. Esimeni esinjalo injini ingase ivele igxume.

Ngokuvamile amafutha alolu hlobo athululelwa ezinjini zesimanje - inqobo nje uma umkhiqizi uncoma ukusebenzisa amafutha alesi viscosity.

Amafutha e-viscosity aphezulu

Amafutha amabanga 50 no-60, ngokuphambene nalokho, ane-viscosity ephakeme, ngakho-ke, ngomqondo ongokomfanekiso, abonakala "eminyene". Ngenxa yalokho, bakha ungqimba olukhulu lwamafutha kanye bavikela kangcono injini ekulayisheni ngokweqile... Ukusetshenziswa kwamafutha anjalo kungaba nomthelela omubi omncane ekusetshenzisweni kukaphethiloli kanye namandla.

Lolu hlobo lwamafutha lusetshenziswa kakhulu. ezinjinini eziguge kabi, nakulabo "abathatha amafutha". Amafutha anamathela kakhulu anganciphisa ukusetshenziswa kukawoyela futhi, ngenxa yezakhiwo zawo zokuvala, ukunciphisa ukususwa kwenjini... Kodwa futhi kwenzeka ukuthi amafutha aphezulu-viscosity batuswa izimoto ezemidlaloukuze uvikele kangcono amadrayivu akho aqinile futhi afunayo.

Ingabe kufanele ngishintshe i-viscosity?

Ephendula umbuzo wesihloko, Amafutha 5W40 (noma 0W40) uphawu oluhle (isb. Castrol, Liqui Moly, Elf) kuzoba ukukhetha okuhle kakhulu ezimeni eziningi.

Ukushintshwa kwamafutha asebusika ane-viscosity ephezulu ezimweni zethu zezulu azikho izaba - kungaholela ezinkingeni ngokuqala imoto ebusika. Okuhlukile lapho sidinga amafutha ane-viscosity yasehlobo ephezulu, futhi amafutha anjalo ane-viscosity, isibonelo, i-10W60.

Ulayini shintsha amafutha abe ngamafutha nge-viscosity yasehlobo ephakeme noma ephansi ngezinye izikhathi kunengqondo (isibonelo, ngenjini yezemidlalo, yesimanje kakhulu noma, ngokuphambene, endala), kodwa isinqumo senziwa kangcono ngemva kokufunda incwadi yemoto kanye nokubonisana nomakhenikha onolwazi.
