Ukungqubuzana nokuguga phakathi kwezingxenye zemishini kukhona kabanzi ezinhlelweni zemishini. Injini iyafana.Ukunciphisa ukungqubuzana nokuguga phakathi kwezingxenye zenjini kubalulekile ekuthuthukiseni ukusebenza kahle kwenjini nempilo yesevisi. Ukungqubuzana akudli nje amandla amaningi, kodwa kungaholela nasekuhlulekeni kwezingxenye ngaphambi kwesikhathi. Ngakho-ke, isihluthulelo sokuxazulula lezi zinkinga sisebuchwephesheni bokugcoba obusebenzayo. Ngokusebenzisa izindlela zokugcoba ezithuthukisiwe, impilo yesevisi yenjini inganwetshwa ngenkathi kunciphisa ukusetshenziswa kwamandla.
I-Graphene, njenge-nanomaterial ekahle yokuthuthukisa ukusebenza kwe-tribological, ithuthukisa izici zokuthambisa zamafutha enjini eyisisekelo. I-Graphene inezinto zokugcoba eziphawulekayo, eziyenza ibe yinto ethembisayo yezinhlelo zokusebenza ezihlukene zezimboni.Enye yezici ezibalulekile ze-graphene ezinikela ezicini zayo zokugcoba isilinganiso sayo esiphezulu sendawo nevolumu. I-graphene iyingqimba eyodwa yama-athomu ekhabhoni ahlelwe ngesakhiwo selathisi lekhekheba lezinyosi. Lesi sakhiwo sihlinzeka ngendawo enkulu kakhulu, evumela i-graphene ukuthi yakhe ifilimu yokugcoba eqinile futhi ezinzile endaweni yezinto ezisebenzisanayo.
Kafushane, izici zokugcoba ze-graphene zisukela endaweni yayo ephezulu, indawo eshelelayo, amandla okuthwala umthwalo, ukuqina kwe-thermal namakhemikhali, i-coefficient ephansi yokungqubuzana, kanye nokumelana nokugqokwa okuphezulu. Lezi zici ezihlukile zenza i-graphene ibe ikhandidethi elikhangayo lokuthuthukisa izinto zokugcoba ezithuthukile ezingathuthukisa kakhulu ukusebenza nokuqina kwezinhlelo ezihlukahlukene zobunjiniyela.
Lapho injini iqalwa, izinhlayiya ze-graphene nano zinika amandla ukungena nokunameka kwemifantu egqokwayo (i-surface asperities) zenze ifilimu elivikelayo elincanyana phakathi kwezingxenye zensimbi zamaphistoni anyakazayo namacyliner.Ngenxa yezinhlayiya ezincane kakhulu zamangqamuzana e-graphene, ingakwazi ukukhiqiza umphumela webhola ngesikhathi ukungqubuzana phakathi kwe-cylinder ne-piston, ukuguqula ukungqubuzana kokuslayida phakathi kwezingxenye zensimbi kube ukungqubuzana phakathi kwezingqimba ze-graphene. ukungqubuzana nokuhuzuka kuncipha kakhulu futhi impushana iyathuthukiswa, ngenxa yalokho konga amandla futhi kuthuthukiswe ukusetshenziswa kahle kukaphethiloli. Ngaphandle kwalokho, ngesikhathi sengcindezi ephezulu kanye nezinga lokushisa, i-graphene izonamathisela endaweni yensimbi futhi ilungise ukuguga kwenjini (ubuchwepheshe be-carburizing), okuzokwandisa impilo yesevisi yenjini. Uma injini isebenza kahle kakhulu, iholela ekwehleni kokukhishwa kwekhabhoni endaweni ezungezile kanye nokuncipha kwemisindo nokudlidliza.
Ukuhlola kubonisa ukuthi ukungqubuzana kwehle kakhulu futhi umphumela wokugcoba uthuthukiswa kakhulu ngemva kokusetshenziswa kwe-graphene enamandla emafutheni.
Izimoto ezinenjini kaphethiloli.
