Ngenxa yezidingo ezikhulayo ekusebenzeni kahle kwezinjini zikadizili, ama-turbocharger angaphansi kwamazinga okushisa aphezulu. Ngenxa yalokho, isivinini se-rotor kanye ne-gradient yokushisa ekusebenzeni kwesikhashana kuba nzima kakhulu ngakho-ke ukucindezeleka okushisayo kanye ne-centrifugal kuyanda.
Ukunquma umjikelezo wempilo wama-turbocharger ngokunembe kakhudlwana, ulwazi oluqondile lokusatshalaliswa kwezinga lokushisa kwesikhashana esondweni le-turbine lubalulekile.
Umehluko ophakeme wamazinga okushisa kuma-turbocharger phakathi kwe-turbine ne-compressor uholela ekudlulisweni kokushisa kusuka ku-turbine kuya ohlangothini lwendlu ye-bearing. Isixazululo esinembe kakhudlwana sifinyelelwe ngokubala uketshezi ekuqaleni kwenqubo ehloliwe yokupholisa ngokuxazulula zonke izibalo. Imiphumela yale ndlela ihlangabezane nezilinganiso zesimo sesikhashana nezinzile kahle kakhulu, futhi ukuziphatha okushisayo kwesikhashana komzimba oqinile kungenziwa kabusha ngokunembile.
Ngakolunye uhlangothi, kakade ngo-2006 amazinga okushisa egesi afika ku-1050 ° C afinyelelwa ezinjinini ezikhishwa uphethiloli. Ngenxa yamazinga okushisa aphezulu e-turbine inlet, ukukhathala kwe-thermomechanical kwagxila kakhulu. Eminyakeni yokugcina izifundo ezimbalwa ezihlobene nokukhathala kwe-thermomechanical kuma-turbocharger zanyatheliswa. Ngokusekelwe kwinkambu yokushisa ebikezelwe futhi eqinisekisiwe ngamanani esondo le-turbine, izibalo zengcindezi zenziwe futhi izindawo zokucindezeleka okushisayo zikhonjwe esondo le-turbine. Kuyaboniswa, ukuthi ubukhulu bengcindezi yokushisa kulezi zindawo bungaba kububanzi obufanayo nobukhulu be-centrifugal stress kuphela, okusho ukuthi ukucindezeleka okubangelwa ukushisa akukwazi ukunganakwa ekuklanyweni kwesondo le-radial turbine.
