Ma Parameters Akuluakulu a GE 7FDL Injini
Mndandanda wa GE 7FDL ndi injini ya dizilo yapakati-stroke inayi yopangidwa ndi General Electric (GE). Imapangidwa kuti ikhale yoyendetsa njanji, komanso imagwiranso ntchito pamakina amagetsi apanyanja ndi mayunitsi opangira magetsi osasunthika. Pansipa pali magawo ake aukadaulo komanso mafotokozedwe atsatanetsatane amitundu yokhala ndi ma silinda osiyanasiyana.
I. Basic Technical Parameters
Tsatanetsatane wa Chinthu cha Parameter

Compression Ratio Pafupifupi 16.5: 1 (kusiyana pang'ono pakati pamitundu yosiyanasiyana)
Kusamutsidwa pa Cylinda iliyonse Pafupifupi 18.68 L (mtengo wowerengeredwa: π×(228.6/2)²×266.7×10⁻⁹)
II. Ma Parameter Enieni a Ma Model okhala ndi Zowerengera Zosiyanasiyana za Cylinder
Nambala Yachitsanzo ya Ma Cylinders Displacement (L) Power Range (hp) Ntchito Zofananira
7FDL-8 8 Pafupifupi 149.4 1,400～1,800 masitima ang'onoang'ono (monga, GE CM20EMP), ma locomotives
7FDL-12 12 Pafupifupi 224.2 2,000～3,300 masitima apakatikati (monga masitima apawiri a GE P32AC-DM)
7FDL-16 16 Pafupifupi 298.9 2,400～4,400 masitima apamtunda akuluakulu (monga AC4400CW, Dash 9-44CW)
