Lintlha tse ka sehloohong tsa GE 7FDL Engine
Letoto la GE 7FDL ke enjene ea disele ea lebelo le mahareng e nang le methapo e mene e entsoeng ke General Electric (GE). E etselitsoe haholo-holo bakeng sa seporo sa terene, hape e sebetsa ho litsamaiso tsa motlakase oa maoatleng le likarolo tsa ho fehla motlakase o emeng. Ka tlase ke likarolo tsa eona tsa mantlha tsa tekheniki le litlhaloso tse qaqileng tsa mehlala e nang le lipalo tse fapaneng tsa li-cylinder.
I. Mekhahlelo ea Motheo ea Theknoloji
Litlhaloso tse qaqileng tsa Ntho ea Parameter
Moetsi GE Litsamaiso tsa Lipalangoang
Nako ea Tlhahiso ea 1956 ho hlahisa (haholo-holo e sebelisoa mefuteng ea ho romela thepa ka mor'a 2004)
Stroke Type Four-stroke
Tokisetso ea Cylinder Tokisetso ea mofuta oa V e nang le 45° e kenyellelitsoeng angle

Reted Speed Range 450~1,050 rpm (lebelo le tloaelehileng la ho sebetsa: 600~900 rpm)
Compression Ratio Hoo e ka bang 16.5:1 (liphapano tse nyane har'a mefuta e fapaneng)
Displacement per Cylinder Hoo e ka bang 18.68 L (boleng bo baliloeng: π×(228.6/2)²×266.7×10⁻⁹)
II. Mekhabiso e Ikhethileng ea Mehlala e nang le Lipalo tse fapaneng tsa Cylinder
Palo ea Moetso oa Li-Cylinders Displacement (L) Matla a Matla (hp) Lits'ebetso tse Tloaelehileng
7FDL-8 8 Hoo e ka bang 149.4 1,400~1,800 literene tse nyenyane (mohlala, GE CM20EMP), li-switching locomotives
7FDL-12 12 Hoo e ka bang 224.2 2,000~3,300 literene tsa boholo bo mahareng (mohlala, GE P32AC-DM terene ea mefuta e 'meli)
7FDL-16 16 Hoo e ka bang 298.9 2,400~4,400 literene tse kholo tsa litsela tse kholo (mohlala, AC4400CW, Dash 9-44CW)
