Pa ntchito ya injini, zitsulo kuvala zinyalala, fumbi, madipoziti mpweya ndi madipoziti colloidal oxidized pa kutentha, madzi, etc. mosalekeza wothira mafuta mafuta.Ntchito ya fyuluta yamafuta ndikusefa zonyansa zamakina ndi ma colloids, kusunga mafuta opaka mafuta kukhala oyera, ndikuwonjezera moyo wake wantchito.Sefa yamafuta iyenera kukhala ndi mphamvu zosefera mwamphamvu, kukana kuyenda kochepa, komanso moyo wautali wautumiki.Nthawi zambiri, zosefera zingapo zokhala ndi mphamvu zosiyanasiyana zosefera zimayikidwa mu zosefera zosefera, zosefera zowoneka bwino ndi zosefera zabwino, zomwe zimalumikizidwa motsatana kapena mndandanda munjira yayikulu yamafuta.(Cholumikizidwa mu mndandanda ndi gawo lalikulu la mafuta chimatchedwa fyuluta yathunthu. Pamene injini ikugwira ntchito, mafuta onse opaka mafuta amasefedwa kudzera mu fyuluta; kufanana komwe kumalumikizidwa nayo kumatchedwa sefa yogawanitsa).Pakati pawo, fyuluta coarse chikugwirizana mndandanda mu ndime yaikulu mafuta, amene ndi mtundu otaya zonse;fyuluta yabwino imalumikizidwa mofanana mumsewu waukulu wamafuta, womwe ndi mtundu wogawanika.Injini zamagalimoto zamakono nthawi zambiri zimakhala ndi zosefera komanso zosefera mafuta.Zosefera zowoneka bwino zimasefa zonyansa zokhala ndi tinthu tating'ono 0.05mm kapena kupitilira apo mumafuta, ndipo fyuluta yabwino imagwiritsidwa ntchito kusefa zonyansa zokhala ndi tinthu tating'ono 0.001mm kapena kupitilira apo.

Makhalidwe aukadaulo

● Pepala losefera: Zosefera zamafuta zimakhala ndi zofunika kwambiri pa pepala losefera kuposa zosefera mpweya, makamaka chifukwa kutentha kwa mafuta kumasiyanasiyana kuchokera ku 0 mpaka 300 madigiri.Pansi pa kusintha kwakukulu kwa kutentha, kuchuluka kwa mafuta kudzasinthanso moyenera.Zidzakhudza kusefa kwa mafuta.Pepala losefera la sefa yamafuta apamwamba kwambiri liyenera kusefa zonyansa pansi pakusintha kwakukulu kwa kutentha ndikuwonetsetsa kuyenda kokwanira.

● Mphete yosindikiza mphira: mphete yosindikizira ya fyuluta ya mafuta a injini yamtengo wapatali imapangidwa ndi mphira wapadera kuti iwonetsetse kuti 100% yatuluka mafuta.

● Backflow suppression valve: imapezeka kokha muzosefera zamafuta apamwamba.Injini ikazimitsidwa, imatha kuletsa fyuluta yamafuta kuti isaume;injini ikayatsidwanso, nthawi yomweyo imatulutsa mphamvu kuti ipereke mafuta kuti azipaka injini.(Amatchedwanso check valve)

● Valavu yothandizira: imapezeka kokha muzosefera zamafuta apamwamba kwambiri.Pamene kutentha kwakunja kumatsikira ku mtengo wina kapena pamene fyuluta ya mafuta ikupitirira moyo wautumiki wamba, valavu yowonongeka idzatsegulidwa pansi pa kupanikizika kwapadera, kulola mafuta osasefedwa kuti ayende molunjika mu injini.Komabe, zonyansa zamafuta zidzalowa mu injini limodzi, koma kuwonongeka kwake kumakhala kochepa kwambiri kuposa kuwonongeka komwe kumabwera chifukwa cha kusowa kwa mafuta mu injini.Chifukwa chake, valavu yakusefukira ndiye chinsinsi choteteza injini pakagwa mwadzidzidzi.(Amatchedwanso bypass valve)
