Kodi kumwa kwamafuta kumatanthauza kuti? Gawo la chimayenda ku chipinda cha kuyaka chifukwa cha kusokoneza mafuta ndipo watenthedwa kapena kupanga kaboni, ndipo gawo linalo limatulutsa kuchokera pamalo pomwe Chisindikizo sichikulimba. Mafuta a seesel nthawi zambiri amalowa m'chipinda cha oyaka oyaka kudzera mu mphete pakati pa mphete ya piston ndi poyambira, komanso kusiyana pakati pa valavu ndi duct. Choyambitsa mwachindunji cha kuthawa kwake ndi mphete yoyamba ya piston pamtunda wapamwamba pafupi ndi liwiro lake loyenda limatsika kwambiri, lidzalumikizidwa ndi mafuta omwe ali pamwambawa amayamba kulowa m'chipinda chochezera. Chifukwa chake, chilolezo pakati pa mphete ya piston ndi piston, mafuta othamangitsa mphete ya piston, kupsinjika mu chipinda cha oyaka chochenjera komanso ma visc.

Kuchokera pamayendedwe ogwiritsira ntchito mafuta omwe amagwiritsidwa ntchito ndi otsika kwambiri, kuthamanga kwa madzi ndi kutentha kwa ma cylinder maymer kumapitirira, kuyambiranso, magawo amavala kwambiri, mafuta Mulingo wokwera kwambiri, etc. ipanga kugwiritsa ntchito mafuta kuwonjezeka. Chifukwa cha kuwerama kwa ndodo yolumikizira, piston woyambitsidwa ndi zosokoneza thupi sizikukwaniritsa zofuna za piston pipitse mphete ya piston ndi mbali ina ya piston Siketi imawoneka ya cylinder limer ndi piston amavala zilembo), ndi chifukwa chachikulu chowonjezerera mafuta.

Kuphatikiza zifukwa zomwe zili pamwambapa, mutha kuwongolera zogwiritsidwa ntchito zamafuta osiyanasiyana monga mphete ya piston ndi piston, kuthamanga kwa chipindacho, etc. zomwe zimakhudzanso kuchepetsa kugwiritsa ntchito mafuta.
