Kodi ndichifukwa chiyani mafuta a injini amatsika nthawi zambiri pambuyo powasintha?
Nthawi zambiri, pambuyo ntchito inakonzedwa kusintha mafuta mu injini, mlingo wake akutsikira patapita nthawi, pamene dalaivala anatha kuyendetsa mpaka makilomita mazana asanu. Tsamba la AvtoVzglyad limafotokoza chifukwa chake kutayikira kumachitika.
Chimodzi mwa zifukwa zambiri banal: mbuye sanali kwathunthu kumangitsa kuda pulagi. Poyenda, pang'onopang'ono anayamba kusungunula, choncho mafuta anathawa. Chifukwa chinanso chofananacho ndi kufuna kusunga ndalama pa zinthu zing’onozing’ono. Chowonadi ndi chakuti chisindikizo cha penny chimayikidwa pansi pa pulagi yokhetsa ndikusinthidwa ndikusintha kulikonse kwamafuta. Sitikulimbikitsidwa kuti mugwiritse ntchito kachiwiri chifukwa pulagi ikamangika, imakhala yopunduka, kuwonetsetsa kulimba kwa dongosolo. Kugwiritsa ntchito kwake mobwerezabwereza kumatha kupangitsa kuti mafuta atayike, chifukwa chake sizoyenera kupulumutsa pazakudya izi.
Mafuta amathanso kuchoka pansi pa mafuta fyuluta gasket, chifukwa mwatsoka ambuye sanali kukoka izo kapena overtightened pa unsembe. Chilema cha fakitale cha fyuluta chimathekanso, momwe thupi lake limangong'amba pamsoko.
Kutaya kwakukulu kungathenso kuchitika pambuyo pa kukonza kwakukulu kwa injini. Mwachitsanzo, chifukwa cha kuwonongeka kwa silinda chipika gasket, ngati amisiri anasonkhanitsa galimoto bwino kapena wothinikizidwa chipika mutu molakwika. Chotsatira chake, mutu kupyolera mu gasket umakanizidwa ndi chipikacho mosagwirizana, zomwe zimabweretsa kuwonongeka m'malo omwe kumangika kwake kumamasulidwa. Chitonthozo chachibale ndi chakuti dalaivala amatha kuona vuto yekha ndi smudges mafuta injini pansi pa mutu wa chipika.
Kutsika kwamafuta kungayambitsenso mavuto akale ndi injini. Mwachitsanzo, zisindikizo za tsinde la valve zinalephera. Zigawozi zimapangidwa ndi mphira wosamva mafuta, koma m'kupita kwa nthawi, chifukwa cha kutentha kwakukulu ndi kupanikizika, mphirayo imataya mphamvu zake ndipo imasiya kugwira ntchito ngati chisindikizo.
Kutayikira kungayambitsidwenso ndi zovuta zamakina amagetsi. Chowonadi ndi chakuti pamene majekeseni amafuta atsekedwa, amayamba kusapopera mafuta, koma kutsanulira mu chipinda choyaka moto. Chifukwa cha izi, mafuta amawotcha mosagwirizana, kuphulika kumawonekera, zomwe zimatsogolera ku maonekedwe a microcracks mu pistoni ndi mphete za pistoni. Chifukwa cha izi, mphete zopangira mafuta zimachotsa filimu yamafuta pamakoma ogwirira ntchito a masilindala mosagwira ntchito. Chifukwa chake zimakhala kuti mafutawo amalowa m'chipinda choyaka moto. Chifukwa chake kuchuluka kwa mtengo.
