Amapharamitha Ayinhloko we-GE 7FDL Engine
Uchungechunge lwe-GE 7FDL iyinjini yedizili enesivinini esinemivimbo emine ekhiqizwe ngabakwaGeneral Electric (GE). Iklanyelwe kakhulu indlela yokuhamba kwezitimela zesitimela, futhi iyasebenza nasezinhlelweni zamandla olwandle kanye namayunithi okuphehla ugesi amile. Ngezansi imingcele yayo yobuchwepheshe eyisisekelo kanye nokucaciswa okuningiliziwe kwamamodeli anezibalo ezihlukene zamasilinda.
I. Imingcele Yezobuchwepheshe Eyisisekelo
Ipharamitha Imininingwane Imininingwane
Umkhiqizi we-GE Transportation Systems
Inkathi Yokukhiqiza 1956 ukwethula (ikakhulukazi esetshenziswa kumamodeli wokuthekelisa ngemuva kuka-2004)
I-Stroke Type Four-stroke
I-Cylinder Arrangement yohlobo lwe-V ilungiselelo eline-engeli engu-45° efakiwe

I-Fuel System Umjovo oqondile
I-Fuel Type Diesel
Isistimu Yokupholisa Ipholile ngamanzi
Ibanga Lejubane Elilinganiselwe 450～1,050 rpm (isivinini sokusebenza esijwayelekile: 600～900 rpm)
I-Compression Ratio Cishe i-16.5:1 (ukwehluka okuncane phakathi kwamamodeli ahlukene)
Ukugudluzwa Kwesilinda Cishe ngu-18.68 L (inani elibaliwe: π×(228.6/2)²×266.7×10⁻⁹)
II. Amapharamitha Akhethekile Amamodeli Anezibalo Ezihlukile Zesilinda
Inombolo Yemodeli Yokusuka Kwamasilinda (L) Ibanga Lamandla (hp) Izicelo Ezivamile
7FDL-8 8 Cishe 149.4 1,400～1,800 izitimela ezincane (isb., GE CM20EMP), ukushintsha izitimela
7FDL-12 12 Cishe 224.2 2,000～3,300 izitimela ezinosayizi omaphakathi (isb., GE P32AC-DM izitimela zemodi ekabili)
7FDL-16 16 Cishe 298.9 2,400～4,400 izitimela ezinkulu zemigqa emikhulu (isb., AC4400CW, Dash 9-44CW)
