Fuel Injector 107-1230 1071230 for Caterpillar 950f 950f II 960f Caterpillar 3114 Engine Caterpillar 3116 Engine

Umthelela wobubanzi be-nozzle, ingcindezi yomjovo kanye nezinga lokushisa elizungezile ezicini zokufutha enjinini kadizili(ingxenye 4)

Njengoba igrafu ikhombisa ubude bokungena kuMfanekiso 9 kanye noFigure 10 kusetshenziswa i-ambient ehlukene.

izinga lokushisa lika-0.12 mm kanye no-0.2 mm we-nozzle ububanzi likhuphuka njalo ngesikhathi esithathiwe futhi kokubili izinga lokushisa ubude bokungena akunikezi okuhluke kakhulu. Lokhu kungenxa yobubanzi obuphakathi kwamazinga okushisa abukho bukhulu kakhulu. Kodwa-ke, ingcindezi yomjovo ithonya ubude bokungena kwesifutho, lapho ingcindezi yomjovo ehlukile engu-40 MPa, 70 MPa kanye no-140 MPa enomfutho we-ambient ongu-1 MPa ngomfutho womkhathi. Njengomjovo ophakeme wokucindezela, ukungena okude ubude kuzothonya. Lokhu kungenxa yokuthi isifutho saphikiswa nengcindezi ye-ambient.

Umfanekiso 11 no-12 ubonisa amagrafu obude bokuhlukana anobubanzi obungu-0.12 mm no-0.2 mm wombhobho. Kunomphumela wokuguquguquka kwezinga lokushisa elingu-500 K, lapho ingcindezi yomjovo engu-140 MPa kanye nobubanzi benobhobho engu-0.2 mm ikhuphuka ngokuphawulekayo isuka ku-1 mm imile iye ku-2.3 mm. Lokhu mhlawumbe kungenxa yokuthi i-droplet ayizange ihlukane futhi iba yinde, lokhu kubizwa njengengxenye ye-ligament. Qhathanisa nezinga lokushisa elingu-700 K ku-140 MPa kanye nobude bokuhlukana obungu-0.2 mm bugeleza ngokungaguquki ngesikhathi. Ngakho-ke izinga lokushisa lithonya izinga lokushisa eliphakeme le-ambient elisetshenzisiwe, ubude obufushane bokuhlukana kwenzeka engxenyeni eyinhloko.

4. Isiphetho

Lolu cwaningo lubonise ukugeleza kokulingisa kukaphethiloli ogeleza kusifutho se-nozzle ngaphambi kokusha. Ukucindezela komjovo ophansi ekamelweni kuzophazamisa ukuhlukana kwesifutho sikaphethiloli sibe amaconsi amancane kakhulu ngaphambi kokuqala ukuthungela kukaphethiloli. Ukushintsha kwezinga lokushisa ekamelweni nakho kuthinta ubude bokungena kwesifutho. Emazingeni okushisa aphezulu e-ambient, isibaseli siyahwamuka kalula futhi sithungele isibaseli ngokwaso. Futhi, ububanzi bombhobho buphinde buthinte ubude bokwehlukana komlomo wesifutho njengoba kuthonywa ingcindezi ephezulu yomjovo lapho ubude bokuhlukana buba bufushane.
