Njengengxenye eyinhloko ohlelweni lwenjini evuthayo yangaphakathi, ukubaluleka kwesayensi kwesihlungi sikaphethiloli akuxhomekile nje kuphela emthelela waso oqondile ekusebenzeni kwenjini kodwa futhi nasekunikeleni kwaso okuphelele ekusebenzeni kahle kwamandla, ukuvikelwa kwemvelo, nokwethembeka kwemishini. Ngokombono wobunjiniyela, izihlungi zikaphethiloli ziqinisekisa ukuhlanzeka kwesistimu yokunikezela uphethiloli ngokusebenzisa izindlela zokuhlunga eziyinkimbinkimbi, ngaleyo ndlela zigcine ukusebenza kwenjini kuzinzile.
Phakathi nenqubo yokusha, ukungcola okunjengezinhlayiya, amanzi, nama-colloid kuphethiloli, uma kungahlungiwe ngokuphumelelayo, kungaholela ekuvaleni komjovo, ukuguga kwamasilinda, ngisho nokuhluleka kwenjini. Izihlungi zesimanje zikaphethiloli zisebenzisa{1}}izihlungi eziyinhlanganisela yezendlalelo eziningi, ezihlanganisa isilawuli sokuqina kobuso kanye nobuchwepheshe bokuhlukaniswa kwe-centrifugal ukuze zibambe kahle ukungcola okungusayizi we-micron{2} kuyilapho kulinganisa ukunemba kokuhlunga kanye nokumelana noketshezi. Lokhu kuthuthuka kwezobuchwepheshe kuthuthukisa kakhulu ukonga kukaphethiloli futhi kunciphisa ukukhishwa kwesisi esibangelwa ukusha okungaphelele, ukuhambisana nezinqubomgomo zomhlaba zokongiwa kwamandla kanye nokunciphisa ukungcola.
Ngokombono wesayensi yezinto, ucwaningo nokuthuthukiswa kwesihlungi sikaphethiloli kuye kwaqhuba ukusetshenziswa kobuchwepheshe be-polymer membrane, imidiya yesihlungi se-nanofiber, kanye nama-alloys ensimbi angagqwali. Isibonelo, ezinye izihlungi eziphezulu{2}}zisebenzisa i-hydrophobic coating ukuze zihlukanise ngokusebenzayo amanzi kuphethiloli futhi zivikele ukugqwala kwe-electrochemical. Izindlela ezintsha ezinjalo azigcini nje ngokunweba impilo yesihlungi kodwa futhi zinciphisa izindleko zokunakekela, okubonisa ukubaluleka okungokoqobo kokuhlanganiswa kobuchwepheshe bemikhakha ehlukene.
Ngaphezu kwalokho, ukuthambekela kwezihlungi zikaphethiloli ezihlakaniphile kuyavela. Ngokuhlanganisa izinzwa zokucindezela kanye namamojula okuqapha ukugeleza,{1}}imikhiqizo emisha yesizukulwane inikeza{2}}impendulo yesikhathi sangempela mayelana nesimo sokuhlunga, ihlinzeka ngosekelo lwedatha lokulungiswa okubikezelwayo. Lokhu kuguquka kobuchwepheshe akugcini nje ngokuthuthukisa ukwethembeka kwesistimu kodwa futhi kwenza isisekelo sezingxenyekazi zekhompuyutha zezimoto ezixhunyiwe kanye nezinhlelo zokuxilonga ezihlakaniphile.
Kafushane, ukubaluleka kwesayensi kwezihlungi zikaphethiloli kudlulela kububanzi bokusebenza bengxenye eyodwa. Ukuvela kwabo kwezobuchwepheshe kunomthelela omkhulu ekusebenzeni kahle kwenjini yangaphakathi, ukusimama kwemvelo, kanye nokukhiqizwa kwezimboni. Ngokuzayo, ngokuthuthuka kwesayensi yezinto kanye nobuchwepheshe bokulawula uketshezi, izihlungi zikaphethiloli zizoqhubeka zidlala indima engenakuthathelwa indawo ekuthuthukisweni kwe-powertrain.
