N855-DM313 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 1800 RPM of CCEC N855-DM313 Marine Auxiliary Engine is 465 HP (347 kW), The Prime power at 1800 RPM of CCEC N855-DM313 Marine Auxiliary Engine is 420 HP (313 kW). The maximum torque of the engine at 1800 RPM is 1840 N.m.
CCEC provides both heat exchanger cooling and radiator cooling marine auxiliary engines, which mainly using for marine main generator and marine emergency generator.
For the emergency generator set applications, we provide additional options for customers such as dual starter motor system (we provide both electric and spring starter motor for customers), which are required by most of international classifications.
All of CCEC marine auxiliary engine are comes with dry type exhaust system, which means dry type exhaust manifold and dry type turbocharger, SeaMac provides upgrading services for water-cooled exhaust system, which modify dry type exhaust system into water-cooled exhaust system, which are quite important and often requested by passenger boat projects.

Advantages of CCEC N855-DM313 Auxiliary Engine

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.
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.
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.
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.
