Kune ngozi sei yakaderera-viscosity mafuta einjini

Munguva pfupi yapfuura, kwave nemaitiro akajeka muindasitiri yemotokari yakanangana nekushandiswa kweakaderera viscosity mota oiri mumainjini emazuva ano. Chii chakakosha pamafuta ekuzora aya?

Kana iwe ukanyatsotarisa mabhurocha ebhizinesi pamusoro pemafuta akaonekwa pazviratidziro mumakore mashanu kusvika manomwe apfuura, uchaona kuti mafuta anochengetedza magetsi ane viscosity yeSAE 0W-20, kazhinji, akatozvisimbisa mune market. Hongu, pakutanga vaibatwa nekuchenjerera uye vakashandiswa chete mumamiriro ezvinhu apo pakanga pasina pachena kusavapo kweimwe nzira, ndiko kuti, apo chete yakapiwa viscosity index yakarongedzerwa kune imwe motokari uye zvimwe zvingasarudzwa zvakajeka zvisingabvumirwi.

Zvishoma nezvishoma, kushushikana pamusoro pezvigadzirwa zvakaderera-viscosity zvakapera, asi matambudziko ane chekuita nemafuta eiyo yakaderera viscosity akaburitswa. Zvakakodzera kugara pane zvimwe zvakakosha zvekushandisa kwavo mune zvakadzama. Saka, semuenzaniso, zvidzidzo zvemafuta akajairwa ekirasi yeSAE 0W-20, yakaitwa kwemakore akati wandei, yakaratidza chokwadi chinotevera: mune mamwe mamiriro ezvinhu, mafuta akadaro anogona kukonzera kuwedzera kupfeka uye kunyange kutadza kushanda kweinjini.

Zvakazoitika kuti chimwe chezvikonzero zvekuremara kwakacherechedzwa kwakabatana nediki gobvu remafuta firimu, iro rinova rakatetepa kana majekiseni akasviba, uye zvakare nekuda kwekudonha kweviscosity kunoitika nekuda kwekupinda kwechisikigo kwechikamu. yemafuta mune lubricant panguva yekushanda kweinjini.

Rimwe dambudziko nderekuzivikanwa kweLSPI (Low Speed ​​​​Pre Ignition) chiitiko, chinokonzeresa kuparadzwa kusingafungidzirwe kwezvikamu zvejini. Sezvo zvidzidzo zvakazotevera zvakaratidza, chiitiko cheLSPI chinobatanidzwa kwete chete nekugadzirwa kwejini, asiwo nemakemikari ekuumbwa kwepakeji yekuwedzera mumafuta ejini. Kunyanya, kumainjini madiki akashongedzerwa turbocharging uye yakananga majekiseni emafuta emafuta, mune dzimwe nguva iyo chaiyo kugadzirwa kweyakajairwa additive package inogona kuva nengozi. Kuti abvise matambudziko akadaro, mumwe nemumwe anogadzira oiri yeinjini akatanga kutsvaga nzira dzake dzekuagadzirisa.

Nhasi, vese vanotungamira vanogadzira mafuta kubva kuU.SA, pamwe nenyika dzeEurope neAsia, kusanganisira China, vanoonekwa mukugadzirwa kwemhando nyowani dzemafuta akaderera-viscosity. Imwe yekutanga kupa budiriro yayo yakasarudzika yaive kambani inozivikanwa yeGerman Liqui Moly, iyo yakatanga mafuta ekutanga emota yeMolygen NG 0W-20 akatevedzana pamusika. Maererano nenyanzvi mumunda wemafuta, chigadzirwa ichi muenzaniso wekubudirira kwakabatanidzwa mhinduro kumatambudziko einjini dzemazuva ano.

Zvakwana kutaura kuti Molygen NG 0W-20 ine yazvino API SN Plus kupatsanura, iyo yakagamuchirwa nevepasi rose bhizinesi nharaunda gore rapfuura. Kuenzaniswa neyakapfuura API SN yakatarwa, iyo nyowani nyowani inowedzera kuramba kune iyo LSPI phenomenon, iyo inowanikwa nekutsiva calcium ne magnesium mune detergent additive package. Iyo seti yezvinowedzera pachayo inochinjirwa kune yakaderera kushanda kwemafuta tembiricha yakajairwa kune mota dzakasanganiswa.

Nekudaro, mutsauko kubva kumafuta akajairwa ane Molygen NG 0W-20 haungogumiri kune imwechete "washing package". Saka, nekuda kweiyo itsva API 3+ base mafuta, Molygen NG 0W-20 ine yakakwirira (ichienzaniswa nemafuta akafanana eiyi viscosity) flash point ye220 ° C, iyo inoderedza zvakanyanya kushandiswa kwemafuta mumainjini akashandiswa. Mukuwedzera, iyo yazvino thickener inoshandiswa mumafuta, iyo inoderedza kukakavara kwemukati mumvura, iyo inowedzera kuvandudza masimba ekuchengetedza simba.

Uye pakupedzisira, "icing pakike" ndeye proprietary anti-wear additive inobva kune organic metal compounds, kaviri inoshanda se "trinuclear molybdenum" inozivikanwa. Kuvapo kwayo mumafuta hakungodziviriri injini kubva pakupfeka uye kuchengetedza mafuta, asi inopawo imwe inishuwarenzi kana paine matambudziko anokonzerwa nepeturu kupinda mumafuta.
