CCEC N855-DM317 Auxiliary Engine

CCEC N855-DM317(1500 RPM) Marine Auxiliary Engine is 6-cylinder inline, 14 liters four-strokes engine with 140 mm (5.5 in) bore and 152 mm (6.0 in) stroke. N855-DM317 Marine Auxiliary Engine equipped with PT Fuel System, comes with turbocharger or LTA, this marine diesel engine complies with IMO-NOx requirements of the International Maritime Organization (IMO). The Overload Capacity power at 1500 RPM of CCEC N855-DM317 Marine Auxiliary Engine is 470 HP (351 kW), The Prime power at 1800 RPM of CCEC N855-DM317 Marine Auxiliary Engine is 425 HP (317 kW). The maximum torque of the engine at 1500 RPM is 2232 N.m.

1.Crankshaft and Rod
Robust and fully balanced crankshaft design for a more steadily rotation and higher strength. Steel pis-ton crown with oil gallery and aluminum skirts for better durability and low oil consumption.
2.Fuel system
Cummins unique PT with fixture and Step Timing control for precise fuel injection make the fuel inject-tion pressure above 120Mpa, which leads to an ex-cellent fuel consumption rate and emission performance. Check valve in fuel tube improve reliability.
3.Lubrication system
Dual spin-on filter can separate impurity above 10um effectively. Low pressure(240-310Kpa) and steady temperature(100-120¡æ) system can reduce auxiliary power wasting of the lubricating oil pump.
4.Cooling system
Great flux water pump and special channel design provide effective cooling. Spin in water filter makes the coolant clean and keeps it in normal acidity.
