High Speed Marine Diesel Engines For 40 KW - 80 KW Generator Sets
Features & Benefits
Cooperated with FEV, German
Solid crankshaft, cylinder and cylinder head made of alloy cast iron, sliding bearing, small bulk, light weight, less vibration, low noise, high reliability, overhaul interval is over 12000 hours.
necking combustion technique pump,1-type high pressure, low inertia, injector with small bore more complete combustion, low fuel consumption, oil seal of valve added, Seal technology for piston ring and valve oil-sealing technique, low fuel consumption.
Optional electronic governor pump
Perfect G-drive for 40-80 KW generator sets
