Sechinhu chakakosha muinjini yekupisa yemukati system, kukosha kwesainzi kwemafuta kwesefa hakungori mukukanganisa kwayo kwakananga pakuita kweinjini asiwo mukupa kwayo kwakazara mukugona kwesimba, kuchengetedza kwezvakatipoteredza, uye kuvimbika kwemuchina. Kubva pamaonero einjiniya, mafirita emafuta anovimbisa kuchena kweiyo mafuta ekupa system kuburikidza neakaomesesa kusefa masisitimu, nekudaro kuchengetedza yakagadzikana kushanda kweinjini.
Munguva yekupisa, kusvibiswa kwakadai sechinhu chinonzi particulate matter, mvura, uye colloids mumafuta, kana zvisina kunyatsopepetwa, zvinogona kutungamirira mukuvharika kwejekiseni, kupfekedzwa kwecylinder, uye kunyange kutadza kweinjini. Masefa emafuta emazuva ano anoshandisa-layer composite sefa zvinhu, kubatanidza tension control necentrifugal separation tekinoroji kuti ibate zvine mutsindo mamicron-saizi inosvibisa uku ichienzanisa kurongeka kwesefa uye kusamira kwemvura. Uku kufambira mberi kwetekinoroji kunonatsiridza hupfumi hwemafuta uye kunoderedza kubuda kwemhepo kunokonzerwa nekupisa kusingakwane, kuenderana nekuchengetedza simba repasi rose uye mitemo yekudzikisa emission.
Kubva pamaonero ezvekushandisa sainzi, tsvakiridzo nebudiriro yemafuta ekufambisa zvakafambiswa nekushandiswa kwepolymer membrane tekinoroji, nanofiber sefa midhiya, nekuora{0}}anodzivirira simbi alloys. Semuyenzaniso, mamwe masefa akakwirira-anoshandisa hydrophobic coating kuparadzanisa mvura kubva mumafuta uye kudzivirira kukoromoka kwemagetsi. Magadzirirwo akadai haangowedzere hupenyu hwesefa chete asi zvakare anoderedza mutengo wekugadzirisa, zvichiratidza kukosha kunoshanda kwekubatanidzwa kwehunyanzvi hwekubatanidza tekinoroji.
Pamusoro pazvo, hunhu hwehungwaru hwemasefa emafuta huri kubuda. Nekubatanidza ma sensors epressure and flow monitoring modules, zvitsva-zvigadzirwa zvechizvarwa zvinopa chaiyo-mhinduro yenguva maererano nekusefa, zvichipa tsigiro yedata yegadziriro yekufungidzira. Iyi shanduko yetekinoroji haingogone kuvimbika kwemechini asi zvakare inoisa hwaro hwehardware yemotokari dzakabatana uye nehungwaru hwekuongorora masisitimu.
Muchidimbu, kukosha kwesainzi kwemafirita emafuta anodarika chiyero chekushanda kwechikamu chimwe chete. Shanduko yavo yetekinoroji ine simba rakakura pakuita kweinjini yekupisa kwemukati, kuchengetedza kwezvakatipoteredza, uye kugadzira maindasitiri. Mune ramangwana, nekubudirira mune zvekushandisa sainzi uye tekinoroji yekudzora tekinoroji, mafirita emafuta acharamba achiita basa risingadzokerike mukugadzirisa powertrain.
