Ente ea diesel ke eona ntho ea bohlokoa ka ho fetisisa ho fihlella ts'ebetso ea enjene ea premium ka mesi e tlase.Ka hona ho latela hore li-injection tsa lienjineri tse sebetsang hantle li tlameha ho laoloa ka nepo.Ka lebaka leo, li-valve tsa hydraulic control valves le orifices li tlameha ho raloa le ho etsoa ka ho nepahala ho phahameng, 'me ho utloisisa boitšoaro ba bona ba mantlha ho tla fana ka tlatsetso ea bohlokoa ts'ebetsong ea ho ntlafatsa le ho lokisa hantle.Delphi e sebelisa motsoako oa papiso le mekhoa e khethehileng ea liteko ho batlisisa litšobotsi tsa phallo ea lisebelisoa tsena.

Joalo ka li-injection tsohle tse ncha, Injector e Phahameng ea Diesel e ntseng e ntlafatsoa Delphi e bile taba ea tšebetso e ngata ea papiso.Se khahlang haholo pampiring ena, ke lipatlisiso tsa CFD tsa mesebetsi ea taolo ea haeteroliki.

Flow cavitation ke sehlooho se tloaelehileng ka thepa ea ente ea diesel;phihlelo e fetileng ea liteko e bontšitse hore mokhoa oa indasteri oa Reynolds-Averaged Navier-Stokes (RANS) o ne o sitoa ho fana ka liphello tse nepahetseng bakeng sa boitšoaro bo matla ba cavitation.Kahoo, ntle le mosebetsi oa CFD, mefuta e meholo (LSM) ea likarolo tse fapaneng tsa mesebetsi ea taolo ea hydraulic e ile ea laeloa.Tšebeliso ea mekhoa e hlakileng ea li-valve tsa taolo le li-orifices ka likala tse ntseng li eketseha haholo li nolofalletsa kutloisiso e tsoetseng pele ea ts'ebetso ea hydraulic [1] e ke keng ea finyelloa habonolo ka mekhoa e meng.Ts'ebetso ea hydraulic e ikemetse ka ho lekaneng ho likala tsohle hore e ka ba molemo joalo ka sesebelisoa sa nts'etsopele.
