Mafuta motsutsana ndi chisanu
M'dera lathu la nyengo, nyengo yozizira imatha kubwera usiku wonse. Kutentha kochepa kwambiri kumatha kulepheretsa galimoto iliyonse, mwachitsanzo pozizira mafuta. Kuti mupewe izi, ndikwanira kudzipangira nokha zowonjezera zowonjezera, zomwe, zikasakanizidwa ndi mafuta, zimapanga chisakanizo chopanda chisanu.
Mavuto a dizilo
Ngakhale kukwera kwa mtengo wamafuta a dizilo, magalimoto okhala ndi injini za dizilo akadali otchuka kwambiri m'dziko lathu. Komabe, muyenera kudziwa kuti kutsika kwamafuta kwa injini izi ndi chifukwa chaukadaulo wapamwamba kwambiri kuposa "ma injini amafuta". Zamakono zamakono zimafuna chisamaliro choyenera. Eni dizilo ayenera kusamala makamaka m'nyengo yozizira. Choyamba, chifukwa cha "kuzizira kwa mafuta", ndipo kachiwiri, chifukwa cha mapulagi owala.
Kudalira kuyambitsa galimoto m'nyengo yozizira pamtundu wa mapulagi owala ndi vuto lomwe limachokera ku mapangidwe a injini ya dizilo. Izi zili choncho chifukwa mpweya wokha umalowa m'masilinda, ndikuukakamiza. Mafuta amabayidwa mwachindunji pamwamba pa pistoni kapena m'chipinda chapadera choyambira. Zinthu zomwe mafuta amadutsamo ziyeneranso kutentha, ndipo iyi ndi ntchito yamapulagi oyaka. Kuyatsa pano sikuyambika ndi spark yamagetsi, koma kumachitika zokha chifukwa cha kuthamanga kwambiri ndi kutentha pamwamba pa pisitoni. Ma spark plugs osweka sangatenthetse bwino chipinda choyaka moto m'nyengo yozizira, pamene chipika chonse cha injini chimazizidwa mochuluka kuposa momwe zilili bwino.
Zomwe tatchulazi "mafuta amaundana" ndi crystallization ya parafini mumafuta a dizilo. Zikuwoneka ngati ma flakes kapena makhiristo ang'onoang'ono omwe amalowa mu fyuluta yamafuta, kutseka, kutsekereza kutuluka kwa mafuta a dizilo muchipinda choyaka.
Pali mitundu iwiri yamafuta amafuta a dizilo: chilimwe ndi chisanu. Ndi malo opangira mafuta omwe amasankha kuti dizilo liti lilowe mu thanki, ndipo madalaivala sayenera kudziwa chifukwa mafuta omwe agwiritsidwa ntchito amatuluka m'mapampu panthawi yoyenera. M'chilimwe, mafuta amatha kuzizira pa 0oC. Mafuta osinthika omwe amapezeka pamasiteshoni kuyambira Okutobala 1 mpaka Novembara 15 amaundana pa -10 ° C, ndipo mafuta achisanu amagawira kuyambira Novembara 16 mpaka Marichi 1, atalemeretsedwa bwino, amaundana pansi -20 ° C (gulu F mafuta achisanu) komanso -32 ° C (Arctic Class 2 Dizilo). Komabe, zitha kuchitika kuti mafuta ena otentha amakhalabe mu thanki, omwe amatsekereza fyuluta.
Kodi kuchita zinthu zikatero? Dikirani kuti mafuta mu thanki asungunuke okha. Ndi bwino ndiye kuyendetsa galimoto mu garaja kutentha. Mafuta sangawonjezere ku mafuta a dizilo. Mapangidwe akale a injini ya dizilo amatha kuthana ndi izi, koma m'mainjini amakono zitha kupangitsa kuti jakisoni awonongeke kwambiri.
Petulo kukana chisanu
Kutentha kochepa sikungowononga mafuta mu injini za dizilo. Mafuta a petulo, ngakhale kuti sagonjetsedwa ndi chisanu kuposa dizilo, amathanso kusinthasintha kutentha. Madzi ozizira mumafuta ndi omwe amachititsa. Mavuto angathe 
kuwoneka ngakhale pakusintha pang'ono kutentha. Tiyenera kukumbukira kuti kuwerengera kwa thermometer kungakhale konyenga, chifukwa kutentha pafupi ndi nthaka kumakhala kochepa kwambiri.
Malo omwe mafuta amaundana nthawi zambiri amakhala ovuta kuwapeza. Njira yotsimikiziridwa, ngakhale yokhalitsa, ndikuyika galimoto mu garaja yotentha. Tsoka ilo, kupukuta uku kumatenga nthawi yayitali. Zabwino kwambiri ndikugwiritsa ntchito zowonjezera zomangira madzi. Ndikoyeneranso kuthira mafuta pamalo opangira mafuta odziwika bwino, pomwe mwayi wokumana ndi mafuta otsika ndi wotsika.
Kupewa, osati kuchiza
N'zosavuta bwino kulimbana ndi zotsatira za kuzizira. Zowonjezera mafuta zomwe zimatsanuliridwa mu thanki pamene kuwonjezera mafuta kumachepetsa chiopsezo cha kuwonongeka kwakukulu.
Ma injini a dizilo amayenera kuthiridwa ndi anti-paraffin asanayambe kuwonjezeredwa. Zosefera zamafuta sizimatsekeka. Ubwino wowonjezera ndikuti ma nozzles amakhalabe oyera ndipo zida zamakina zimatetezedwa ku dzimbiri. Mankhwala monga DFA-39 opangidwa ndi K2 amawonjezera kuchuluka kwa mafuta a dizilo, omwe amathandiza kuchepetsa kuwonongeka kwa injini ya dizilo m'nyengo yozizira.
Ndibwino kuti muthire K2 Anti Frost mu thanki musanawonjezere mafuta. Amamangirira madzi pansi pa thanki, kusungunula mafuta ndikuletsa kuzizira kachiwiri. Komanso, musaiwale kuyendetsa ndi tanki yodzaza kwambiri m'nyengo yozizira, njirayi sikuti imateteza ku dzimbiri, komanso imapangitsa kuti injiniyo ikhale yosavuta. Mafuta akazizira, samasintha nthunzi bwino. Izi zimapangitsa kuti zikhale zovuta kuyatsa kusakaniza mu silinda, makamaka pamene kuli kochepa kwambiri.
Kuyika ndalama zokwana zloty khumi ndi ziwiri muzowonjezera mafuta m'nyengo yozizira ndi lingaliro labwino kwambiri. Kuwonjezera pa kusunga nthawi, dalaivala amapewa kupanikizika kowonjezereka komwe kumagwirizanitsidwa, mwachitsanzo, ndi kuyenda. Palibenso chifukwa choyang'ana ma patent kuti achepetse mwachangu mafuta, zomwe zingakhale zodula. Ndi bwino kukhala m'mawa wozizira kwambiri m'galimoto yotentha kusiyana ndi kukhala m'basi kapena tram yodzaza.
