Ndinofanira kuchinja mafuta einjini yangu nguva yechando isati yasvika?
Single giredhi mota oiri chinhu chekare. Dai zvanga zvisina kudaro, zvitoro zvekugadzira motokari nechando chekutanga zvingave zvakakombwa, kwete chete nekuda kwekuchinja kwetai, asiwo nekuda kwekudiwa kwekuchinja injini yemafuta kuchando. Parizvino, vagadziri vemotokari vanokurudzira kuchinja injini yemafuta mushure meimwe nhamba yemakiromita kana kamwechete pagore. Zvinokurudzirwa "kamwe chete pagore" zvinoreva kuti zvakakodzera kutsiva nguva yechando isati yasvika here?
Chivimbiso chekutanga nyore uye kutyaira kwakachengeteka munguva yechando - iyi ndiyo nzira iyo mugadziri wemafuta akashambadza nayo muma30s 
Mob. Mobiloil Arctic, iyo yakapihwa vatyairi panguva iyoyo, yaive mono-giredhi oiri yaifanira kuchinjwa sezvo mwaka wachinja. Sezvaunogona kuverenga mumatura emotokari, mafuta aya akagadziridzwa zvakanyanya kumamiriro akanyanya ekushanda kweinjini yechando. Kubatsira kwayo pamusoro pemakwikwi kwaiva kuti pasinei nekutsanangurwa kwayo kwechando, yaifanira kupa kuchengetedzwa kwakanakisisa kune injini inopisa. Dziviriro yakakwana kunyange pa400 degrees Fahrenheit (inenge 200 °C), mapepanhau eNew York akashuma muna 1933. Nhasi, mafuta emota anoshandiswa muinjini dzemitambo anofanirwa kumira tembiricha inosvika 300 ° C - mamiriro akadai seMobil 1 mafuta mumotokari yeVodafone McLaren Mercedes timu.
Kusarudzwa kwemafuta ejini yemhando yakakodzera kune zvakakosha pakushanda kwemotokari munguva yechando. Panyaya iyi, maoiri ekugadzira zvakajeka kupfuura semi-synthetic uye mineral oiri. Kune maviri ekupedzisira, kuchinja kwemafuta kusati kwasvika nguva yechando kunogona kuva chisarudzo chekuchenjera. Oiri yeinjini inorasikirwa nemaparamita ayo nemakiromita ese akafamba. Iyo inoratidzirwa kune yakanyanya kupisa uye oxidized. Mhedzisiro ndeyekuchinja kwe physico-chemical properties. Izvi zvinoshandawo kune zvakaderera-kupisa zvinhu, izvo kushanda zvakanaka kwemotokari yedu kunoenderana munguva yechando, nokuda kwemafuta ekugadzira kuchinja uku kunoitika zvishoma nezvishoma, uye mafuta anochengetedza kushanda kwayo kwenguva refu.
Kusviba kwemafuta kunoreva here kuti iri kurasika zvinhu zvayo?
Kuongorora kukodzera kwemafuta enjini kunouya nengano mbiri. Kutanga, kana mafuta einjini yako aita rima, inguva yekufunga nezve kuichinja. Chechipiri ngano yakajairika pakati pevatyairi ndeyekuti mafuta emota haachembera mumotokari isina kushandiswa. Nehurombo, kuwanikwa kwemhepo (okisijeni) uye kudzoreredzwa kwemhute yemvura inoshandura zvakanyanya zvimiro zveoiri inosara muinjini isina basa. Muchokwadi, mafuta anochinja ruvara rwawo makumi emakumi emakiromita mushure mekuchinja. Izvi zvinokonzerwa nekusvibiswa kusina kubviswa nemafuta ekare, pamwe nekusvibiswa kwakagadzirwa panguva yekupisa, inotsanangura Przemysław Szczepaniak, ExxonMobil's automotive lubricant specialist.
Sei uchisarudza mafuta ekugadzira?
Kana zvinokurudzirwa nemugadziri wemotokari zvichibvumira, zvakakosha kushandisa mafuta ekugadzira, ayo anozochengetedza injini munguva yechando. Mafuta emazuva ano ekugadzira anokurumidza kusvika korona yepiston, conrod end bearings, uye dzimwe nzvimbo dziri kure dzekuzora mushure mekunge mota yatangwa. Synthetic ndiye mutungamiri asina kupokana, uye mukwikwidzi wayo imineral oiri; pakudziya kwakadzika, inotoda masekondi mashoma kuchengetedza ese ejini zvikamu. Kusakwana kwemafuta kunogona kukonzera kukuvadza kwakakomba kusingawanzo kuoneka pakarepo asi kunozoonekwa nekufamba kwenguva nenzira, semuenzaniso, yakawandisa injini kushandiswa kwemafuta, kuderera kwekumanikidza uye kurasikirwa kweinjini simba. Pasina kuyerera kwemafuta, simbi-ku-metal friction mumabhengi inogona kukuvadza injini panguva yekutanga-up.
Kuchengeta mafuta emafuta pakudziya kwakadzika kunoita kuti zvive nyore kutanga injini uye inopa kupisa kuri nani. Naizvozvo, kana isu tine hanya nezve yakanaka kuchengetedzwa kweinjini munguva yechando, zvakakodzera kushandisa mafuta ekugadzira uye, pamusoro pezvose, kutevera inokurudzirwa shanduko yebasa. Nokudaro, tichava nechokwadi chokuti mafuta achachengetedza zvinhu zvayo, izvo zvinonyanya kukosha mumamiriro ezvinhu akaoma ekushanda. Uye isu tichatongerwa izvozvi mumwedzi yechando.
