The prime power at 1800 RPM of CCEC KTA50-M2-1700 Marine Main Engine is 1700 HP (1268 kW). The maximum torque of the engine at 1500 RPM is 7020 N.m.

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 KTA50-M2-1700 Marine Engine

  • It meets the requirements of China Inland River 1, China Inland River 2, and IMO TIER2 stage emission regulations, and adopts the BHT3B supercharger optimized by Chongqing CMI for marine engines. 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.

  • The design of the exhaust system of Chongqing CMI marine engine is reasonable, and the water-cooled supercharger and water-cooled exhaust pipe can better reduce the surface temperature of the engine and meet the requirements of SOLAS safety regulations.

  • It has passed the certification of many national classification societies such as China CCS and French BV.

  • Overall modular design, block integration, compact structure, parts can be split, high reusability.
