Mafura a kenngoa ka kamoreng a bohlokoa ho enjene ea diesel hobane e susumetsa ts'ebetso le tlhahiso.Nakong ea mollo, sefafatsi ke feela ho kenngoa ha mokelikeli tikolohong e nang le khase ka molomo oa molomo hoo mokelikeli, ka ho sebelisana ha oona le khase e potolohileng le ka ho se tsitse ha oona, o phatloha ho ba marotholi [1].Litšobotsi tsa spray li tsebahala ka ho ama haholo ts'ebetso ea ho tuka le ho tsoa lienjineng tsa disele.Ka ho ntlafatsa litšoaneleho tsa spray, likhase tse tala tse tsoang enjeneng ea diesel tseo haholo-holo NOx le PM li ka fokotsoang [2-4].Lipatlisiso tsa litšobotsi tsa li-sprays tsa diesel li tsepamisitse maikutlo holim'a phello ea tšobotsi ea spray mosebetsing oa enjene joalo ka ho kenella ha ntlha ea spray, bolelele ba marotholi le boholo ba marotholi le kabo ea lebelo [5]. ].Ho kenella ha ntlha ea spray ho nka nako e telele ha khatello ea ente e ntse e eketseha.Sephetho sena se amana le bongata bo phahameng le lebelo le phahameng la marotholi ka khatello e phahameng ea ente [7].Ho ea ka khatello ea ente, spray e kenella ka potlako ka likhatello tse phahameng tsa ente [8].The khefu-up bolelele tšoaea ntlha ea discontinuity, moo spray fetoha ho tloha sebakeng sa mokelikeli (boholo mokelikeli, kapa interconnected ligaments le marotholi), ho puso e khabeloa atomized ea marotholi [9].Ka mor'a ho qhalana ha kholomo ea mokelikeli e hlahang molomong, marotholi a hlahisoang a ka 'na a arohana ho ba a manyenyane ha a ntse a kena ka har'a khase e potolohileng [10].Ntlafatso ea deformation ena e lebisa ho khaohaneng ho ba marotholi a manyane.

Matla a amanang le khatello e matla, tsitsipano ea holim'a metsi le viscosity e laola ho arohana ha lerotholi [11-12].Leha ho le joalo, CFD ke sesebelisoa sa ho sekisetsa se sebelisoang ho bolela esale pele karolo ea bohlokoa e ke keng ea etsoa litekong.Patlisisong ena, ho batlisisoa litšobotsi tsa diesel ea spray ho shebane le ho fetola mocheso o tikolohong, khatello ea ente ka bophara bo fapaneng ba nozzle ka ho sebelisa Computational Fluid Dynamics.Ketsiso ena e ka hapa bophara ba marotholi, ho kenella ha spray le bolelele ba ho arohana.
