Main Parameters yeGE 7FDL Injini
Iyo GE 7FDL yakatevedzana iine-stroke yepakati-kumhanya dhiziri injini yakagadzirwa neGeneral Electric (GE). Iyo inonyanya kugadzirirwa njanji locomotive traction, uye zvakare inoshanda kune marine magetsi masisitimu uye akamira emagetsi ekugadzira mayunitsi. Pazasi pane ayo epakati tekinoroji ma paramita uye akatsanangurwa akatsanangurwa mamodheru ane akasiyana cylinder kuverenga.
