Nthawi zambiri, injini imakhala ndi chodabwitsa cha kumwa mafuta, ndipo kugwiritsa ntchito mafuta osiyanasiyana munthawi inayake sikufanana, koma malinga ngati sikudutsa mtengo wake, ndi chinthu chachilendo.
Mafuta otchedwa "woyaka" amatanthauza kuti mafuta amalowa m'chipinda choyaka moto cha injini ndikuchita nawo kuyaka pamodzi ndi kusakaniza, zomwe zimachititsa kuti pakhale vuto la kumwa kwambiri mafuta. Ndiye chifukwa chiyani injini imawotcha mafuta? Chifukwa chiyani mafuta ambiri amadya?
Kutuluka kwa mafuta kunja
Pali zinthu zambiri zomwe zimayambitsa kutayikira kwamafuta, kuphatikiza: mizere yamafuta, ngalande zamafuta, ma poto amafuta, ma gaskets ophimba ma valve, ma gaskets a pampu yamafuta, ma gaskets a pampu yamafuta, zisindikizo zotsekera nthawi ndi zisindikizo za camshaft. Zomwe zili pamwambapa zomwe zitha kutayikira sizinganyalanyazidwe, chifukwa ngakhale kutulutsa pang'ono kungayambitse kuchuluka kwa mafuta. Njira yodziwira kutayikira ndikuyika nsalu yopepuka pansi pa injini ndikuyiyang'ana mutayamba injini.
Kulephera kwa chisindikizo cha mafuta kutsogolo ndi kumbuyo
Zisindikizo zazikulu zokhala ndi mafuta owonongeka kutsogolo ndi kumbuyo zidzachititsa kuti mafuta atayike. Izi zitha kudziwika pokhapokha injini ikugwira ntchito. Chisindikizo chachikulu chamafuta chiyenera kusinthidwa pambuyo pa kuvala, chifukwa monga kutuluka kwa mafuta, kumayambitsa kutsika kwakukulu.
Main kubala kuvala kapena kulephera
Zovala zazikulu zotha kapena zolakwika zimatha kukwapula mafuta ochulukirapo ndikuponyedwa pamakoma a silinda. Pamene kuchuluka kwa mafuta kumawonjezeka, mafuta ambiri amachotsedwa. Mwachitsanzo, ngati chilolezo cha 0.04 mm chimapereka kudzoza ndi kuziziritsa kwabwinobwino, kuchuluka kwa mafuta otayidwa ndikwabwinobwino ngati chilolezocho chikhoza kusungidwa. Pamene kusiyana kwawonjezeka kufika pa 0,08 mm, kuchuluka kwa mafuta otayidwa kudzakhala 5 nthawi zambiri. Ngati chilolezo chikuwonjezeka kufika pa 0.16mm, kuchuluka kwa mafuta otayidwa kudzakhala 25 nthawi zonse. Ngati chonyamula chachikulu chiponya mafuta ochulukirapo, mafuta ochulukirapo amawaza pa silinda, kulepheretsa mphete za pistoni ndi piston kuwongolera bwino mafuta.
Chovala cholumikizira ndodo chowotcha kapena chowonongeka
Zotsatira za kulumikiza ndodo yonyamula chilolezo pa mafuta ndizofanana ndi zomwe zimayendera kwambiri. Kuphatikiza apo, mafutawo amaponyedwa mwachindunji pamakoma a silinda. Zomangira zomangira zowonongeka kapena zowonongeka zimapangitsa kuti mafuta ochulukirapo aponyedwe pamakoma a silinda, ndipo mafuta ochulukirapo amatha kulowa muchipinda choyaka ndikuwotchedwa. Zindikirani: Chilolezo chosakwanira sichidzangopangitsa kuti chivale chokha, komanso kuvala pa pistoni, mphete za pistoni ndi makoma a silinda.
