Injini yamagalimoto ndi njira yamphamvu yagalimoto. Mafuta agalimoto ndiwofunikanso kwambiri, ntchito yake, kuziziritsa, kupewa kukangana kwachitsulo, kudzoza ndi ntchito zina, pakangotha ​​​​mavuto amafuta agalimoto, kukhudzidwa kwagalimoto kumakhala kwakukulu kwambiri, zotsatirazi ndizochepa pang'ono zamafuta a injini yamagalimoto kulephera kwachilendo. kusanthula.

1. Kuthamanga kwa mafuta nthawi zonse kumakhala kochepa kwambiri

Sensa yamafuta amafuta nthawi zambiri imayikidwa mumsewu waukulu wamafuta, ngati choyezera kuthamanga kwamafuta ndi sensa yamafuta ndi yachilendo, ndipo choyezera chamafuta chikuwonetsa kuti kupanikizika ndikotsika kwambiri, zomwe zingakupangitseni kulephera zitha kufufuzidwa molingana ndi kapangidwe ka mafuta odzola komanso kuzungulira kwamafuta. Ngati dera lamafuta ligawika kutsogolo ndi kumbuyo mbali ziwiri molingana ndi kayendedwe ka mafuta ndi sensa yamafuta, zifukwa zochepetsera mafuta zitha kugawidwa m'magawo awiri: choyamba, gawo lamafuta lisanachitike sensa yamafuta. sichaulere kapena mafuta osakwanira; Chachiwiri, kukhetsa kwamafuta pambuyo pa sensa yamphamvu yamafuta ndikuthamanga kwambiri. Ngakhale pali kusiyana pakati pa kapangidwe ka mafuta ndi kayendedwe ka mafuta a injini zosiyanasiyana, sikovuta kuzindikira vuto la kutsika kwamafuta otsika malinga ndi malingaliro omwe ali pamwambapa.

2. Kuthamanga kwa mafuta kumatsika mwadzidzidzi

Kuchepetsa kwadzidzidzi kwa kuthamanga kwamafuta nthawi zambiri kumakhala kutayikira kwakukulu kwamafuta, monga kutsekeka kwa waya wa chitoliro chamafuta, kuphulika kwa chitoliro chamafuta, ndi zina zambiri, kumapangitsa kuti mafuta azichulukirachulukira, ndipo kupanikizika kwamafuta komwe kumawonetsedwa muntchito ya injini kumakhala kotsika kwambiri. Kuwonongeka kwa pampu yamafuta, monga pampu yamafuta amafuta ndi nyumba yapampu, shaft yapampu ndi kunyamula pakati pa kuvala kwakukulu, kapena kulephera kwapampu yapampu kuphwanyidwa kwamphamvu ndi zifukwa zina, kotero kuti mpope wamafuta sungathe kukhazikitsa kuthamanga kwanthawi zonse; Zitha kukhalanso kuti olowa payipi olumikizidwa ndi mpope mafuta ndi lotayirira kapena losweka, ndi mafuta fyuluta watsekedwa, etc., zomwe zingachititse kuti mafuta dongosolo mafuta mpope sangathe kukhazikitsa wamba ntchito kuthamanga, kuti injini. Kuthamanga kwa mafuta kumakhala kochepa kapena ngakhale palibe. Izi zikachitika, injiniyo iyenera kuzimitsidwa nthawi yomweyo kuti ipewe ngozi zazikulu zamakina. Kenako chotsani poto yamafuta a injini, yang'anani poyang'ana malo otayira ndi mpope wamafuta.
