Ngenxa yokwanda kweemfuno ekusebenzeni kakuhle kweenjini zedizili, ii-turbocharger ziphantsi kobushushu obuphezulu.Ngenxa yoko, isantya se-rotor kunye neqondo lobushushu kwimisebenzi edlulayo inzima kakhulu kwaye ngenxa yoko uxinzelelo lwe-thermal kunye ne-centrifugal luyanda.
Ukumisela umjikelo wobomi bee-turbocharger ngokuchanekileyo ngakumbi, ulwazi oluchanekileyo lokusasazwa kobushushu okwethutyana kwivili leinjini yomoya lubalulekile.
Umahluko ophezulu wobushushu kwii-turbocharger phakathi kwe-iturbine kunye ne-compressor ukhokelela ekugqithiseni ubushushu ukusuka kwi-injini ukuya kwicala lendlu yokuthwala.Isisombululo esichane ngakumbi siphunyeziwe ngokubala ulwelo ekuqaleni kwenkqubo evavanyiweyo yokupholisa ngokusombulula okwethutyana zonke iiequations.Iziphumo zale ndlela zidibene nemilinganiselo yexesha elifutshane kunye nesigxina kakuhle, kwaye ukuziphatha okwethutyana kwe-thermal yomzimba oqinileyo kunokuveliswa ngokuchanekileyo.
Ngakolunye uhlangothi, sele sele kwi-2006 ukushisa kwegesi ukuya kwi-1050 ° C kwafikelelwa kwiinjini zepetroli.Ngenxa yobushushu obuphezulu bokungena kwi-injini yomoya, ukudinwa kwe-thermomechanical kuye kwagxila ngakumbi.Kwiminyaka yokugqibela izifundo ezininzi ezinxulumene nokudinwa kwe-thermomechanical kwii-turbocharger zapapashwa.Ngokusekwe kwibala lobushushu eliqikelelweyo eliqikelelweyo neliqinisekisiweyo kwivili leinjini yomoya, ubalo loxinzelelo lwenziwa kwaye imimandla yoxinzelelo oluphezulu lwe-thermal ichongiwe kwivili leinjini yomoya.Kuboniswa, ukuba ubukhulu boxinzelelo lwe-thermal kule mimandla bunokuba kuluhlu olufanayo nobukhulu boxinzelelo lwe-centrifugal kuphela, oku kuthetha ukuba uxinzelelo olubangelwa yi-thermal alukwazi ukungahoywa kwinkqubo yoyilo lwevili le-radial turbine.
