CCEC NT855-M147 (1600 RPM) Marine Main Engine is 6-cylinder inline, 14 liters four-strokes engine with 140 mm (5.5 in) bore and 152 mm (6.0 in) stroke.

NT855-M147 Marine Main Engine equipped with PT Fuel System, comes with turbocharger, this marine diesel engine complies with IMO-NOx requirements of the International Maritime Organization (IMO). The continuous power at 1600 RPM of CCEC NT855-M147 Marine Main Engine is 147 HP (110 kW). 

Based on standard CCEC marine main engines, SeaMac provides both heat exchanger cooling and keel cooling marine main engines, we also provide complete propulsion system that including marine engine, gearbox, shaft, propeller as complete power system.

SeaMac provides full life cycle services for all our customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

All of CCEC marine main 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 NT855-M147 Marine Engine

  • NT series marine engine has stable performance, sufficient combustion, low failure rate, fast starting, good acceleration, strong cooling, high injection pressure, perfect detection characteristics, good transient response, high reliability and durability.

  • It meets the requirements of IMO TIER2 emission regulations, and adopts CMI high-efficiency supercharger and high-efficiency intercooler to make the engine run efficiently, and the application of low-temperature intercooler technology greatly reduces fuel consumption and emissions, while enhancing engine reliability.

  • With high injection pressure, overspeed protection, low-pressure fuel supply, fewer pipelines, and low failure rate, it can ensure full fuel combustion and achieve high-efficiency energy-saving effects. The equipped ESTC electronic oil timing control valve can accurately supplement and adjust the timing and improve the combustion smoke color at low idle speed.

  • Overall modular design, block integration, compact structure, detachable parts, high reusability.

  • Cylinder block and cylinder head adopt integrated design, low failure rate, excellent lubrication system, low parasitic power, durability and excellent reputation.
