IiParameters eziphambili ze-GE 7FDL Injini
Uthotho lwe-GE 7FDL yinjini yedizili enesantya esiphakathi esine-stroke eyenziwe nguGeneral Electric (GE). Ilungiselelwe ubukhulu becala ukutsalwa kukaloliwe kaloliwe, kwaye ikwasebenza kwiinkqubo zamandla aselwandle kunye neeyunithi zokuvelisa umbane omileyo. Ngezantsi iiparitha zayo eziphambili zobugcisa kunye neenkcukacha ezicacileyo zeemodeli ezinamanani ahlukeneyo e-cylinder.
I. IiParameters ezisisiseko zobuGcisa
I-Parameter Inkcazo eneenkcukacha
IiNkqubo zoThutho ze-GE zomvelisi
Ixesha leMveliso 1956 ukuza kuthi ga (ikakhulu lisetyenziswa kwiimodeli zokuthumela ngaphandle emva ko-2004)
I-Stroke Type Four-stroke
I-Cylinder Arrangement i-V-type ilungiselelo kunye ne-45 ° ifakiwe engile
I-Cylinder Bore 9 intshi (228.6 mm)
I-Piston Stroke 10.5 intshi (266.7 mm)
Indlela yokuTshaja kakhulu Ukukhupha irhasi kwi-turbocharging
I-Fuel System Isitofu esithe ngqo
I-Fuel Type Diesel
Inkqubo yokupholisa Ukupholisa ngamanzi
Uluhlu lwesantya esilinganisiweyo 450～1,050 rpm (isantya esiqhelekileyo sokusebenza: 600～900 rpm)
Umlinganiselo woxinzelelo malunga ne-16.5: 1 (utshintsho oluncinci phakathi kweemodeli ezahlukeneyo)
Ukushenxiswa ngokweSilinda Malunga ne-18.68 L (ixabiso elibaliweyo: π×(228.6/2)²×266.7×10⁻⁹)
II. IiParameters eziKhethekileyo zeeModeli ezinezibalo ezahlukeneyo zeCylinder
Inani leModeli yeeSilinda zokuThuthwa (L) Uluhlu lwaMandla (hp) Usetyenziso oluQhelekileyo
7FDL-8 8 Malunga ne-149.4 1,400～1,800 izitimela ezincinci (umzekelo, i-GE CM20EMP), iilomathi ezitshintshayo
7FDL-12 12 Malunga nama-224.2 2,000～3,300 izitimela ezinobungakanani obuphakathi (umzekelo, iGE P32AC-DM isitimela semowudi ezimbini)
7FDL-16 16 Ngokumalunga nama-298.9 2,400～4,400 iiloti ezinkulu ezinkulu (umzekelo, AC4400CW, Dash 9-44CW)
