Zvinoita here kubvisa tsvina yemafuta einjini nekuitsiva

Anenge muridzi wese wemotokari anotya uye anotya zvakanyanya kana mwero wemafuta mumotokari uchidzika. Mushure mezvose, izvi zvinoratidza kusashanda kweinjini uye kugadzirisa mune ramangwana. Naizvozvo, mutyairi anofanirwa kutarisa mwero kuti adzivise mitengo yakakwira.

Iyo injini yemafuta inogara ichidzika nekuda kwehutsi?

Kusvirwa ndiko kupisa kweoiri muinjini. Asi inogona "kusiya" injini kwete chete panguva yekupisa, asi nezvimwe zvikonzero zvakawanda:

1. Oiri inogona kudonha kubva pasi pevhavha yevhavha payakange yakadzvanywa zvakashata kana gasket yakakuvadzwa. Kuti uone dambudziko iri harisi rakaoma, unoda kutarisa pasi pehood.
2. Iyo crankshaft oiri chisimbiso inogona zvakare kuve iyo yakakonzera lubricant kuvuza. Kuti uone dambudziko iri, unogona kutarisa nzvimbo iyo motokari yaive uye kana pane dhaka remafuta, zvino zvinogoneka kuti ichi chisimbiso chemafuta. Iri idambudziko rakajairika. Inogona kuitika nekuda kwemafuta akaipa kana kupfeka kwechisimbiso chemafuta pachayo.
3. Pakutsiva iyo sefa yemafuta, vanogona kukanganwa kuisa chisimbiso chingamu, kana kusanyatsosimbisa sefa pachayo. Inogonawo kukonzera kuvuza. Tarisa kuti sefa yakamonyoroka sei, pamwe nemhando yerubha yekuvharisa.
4. Chimwe chikonzero chiri nyore chinogona kunge chiri mavharuvhu stem seals (iwo mavharuvhu zvisimbiso). Iyo inogadzirwa kubva kune inopisa-inodzivirira rubber, asi inoramba iine rubber, uye nekuda kwekushisa kwepamusoro, zvivharo zvinotanga kutaridzika sepurasitiki, iyo isingaiti basa rayo uye lubricant inotanga "kubva".

Kupisa kweoiri kunotsamira pachezvako here

Oh chokwadi. Mafuta akasarudzwa zvisiri izvo anogona kusasangana nezviyero zveinjini iyi uye kupera simba kunogona kukonzera.

Ndeapi maparameter emafuta anokanganisa tsvina

Zvinhu zvakawanda zvinokonzeresa kuwanda kwemafuta anopisa muinjini:

• Evaporation maererano nenzira yeNoack. Iyi nzira inoratidza katsika kekuzora mafuta kana kupisa. Iyo yakaderera chiratidzo ichi, (inoratidzwa mu%), zviri nani (zvishoma zvinopera). Mafuta emhando yepamusoro anofanirwa kunge aine isingasviki 14 muzana yechiratidzo ichi.
• Base mafuta mhando. Kubva mundima yapfuura, unogona kuona kuti "base" yaive yakanaka sei panguva yekugadzira. Iyo yakaderera nhamba yaNoack, zviri nani iyo "base" yaive.
• Viscosity. Iyo yakakwirira viscosity, yakaderera iyo Noack index. Ndicho chikonzero, kuderedza marara, unogona kushandura kune mamwe mafuta e-viscous. Semuenzaniso, iwe unozadza 10W-40 mafuta uye nekuwanda kwekupisa, unogona kushandura ku15W-40 kana kunyange 20W-40. Zvave zvichiratidzwa kuti musiyano pakati pemarara e10W-40 uye 15W-40 inenge 3.5 units. Kunyangwe mutsauko unoratidzika kunge mudiki unogona kukanganisa kushandiswa.
• HTHS. Inomirira "High Temperature High Shea", kana yakashandurwa, ichava "High Temperature - Big Shift". Kukosha kwechiratidzo ichi kunokonzera viscosity yemafuta. Motokari nyowani dzinoshandisa oiri ine chiratidzo cheiyo kukosha isingasviki 3,5 MPa * s. Kana rudzi urwu rwemafuta rukadururirwa mumotokari yakwegura, zvino izvi zvichaita kuti kuderera kwefirimu yekudzivirira pamasilinda uye kushanduka kukuru, semugumisiro, kuwedzera kwemarara.

Ndeapi mafuta anoderedza kushandiswa kwete nekuda kwemarara

Huwandu hwekupisa lubricant hunogona kuderedzwa nerubatsiro rwezvinowedzera. Kune nhamba huru yavo. Vano "blur over" makwara muhumburumbira, nekudaro vachidzikisa tsvina.

Nzira yekusarudza mafuta asingasviki

Kuti urege kuverengera, unogona kushandisa nzira mbiri:

1. Ona wongororo. Iwe unogona kuenda kune saiti yekutengeswa kwemafuta uye woona wongororo kune yega yega sarudzo yekufarira. Iwe unogona zvakare kuenda kumaforamu akasiyana kwavanokurukura mafuta einjini, kune akawanda awo.
2. Zviongorore. Iyi nzira yakakodzera kune vanhu vanofarira kutora njodzi kana kusatenda wongororo. Kana iwe wakaita seizvi, saka bhizinesi iri rinogona kudhonza kwenguva yakareba, nekuti iwe unofanirwa kutenga mafuta, kuizadza mukati, kutyaira 8-10 zviuru zvemakiromita, uye wozoongorora chete kunaka kwayo uye mamwe maitiro.

Oiri inowanzopisa kunyange painjini itsva. Kana iyo nhanho yadonha, unofanirwa kutarisa crankshaft mafuta chisimbiso, chivharo chevharuvhu, mavharuvhu stem seals uye oiri sefa imba yekudonha. Zvakare, usati watenga mafuta, unofanirwa kuziva kuti ndeupi mafuta akakodzera injini yako.

Kuti uderedze kupera simba, unogona kushandura kumafuta akakora. Uye kana mafuta "akasiya" malita emakiromita 1-2 zviuru, ipapo kugadzirisa kukuru chete kuchabatsira. Rombo rakanaka munzira uye tarisa mota yako!
