KTA19-M3-640 Marine Main Engine equipped with PT Fuel System, comes with turbocharger and Water-Air intercooler, this marine diesel engine complies with IMO-NOx requirements of the International Maritime Organization (IMO). The Advertised Power at 1800 RPM of CCEC KTA19-M3-640 Marine Main Engine is 640 HP (477 kW). The maximum torque of the engine at 1400 RPM is 2830 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 KTA19-M3-640 Marine Engine

  • The cylinder block and cylinder head adopt integrated design, which prevents the occurrence of water leakage and oil leakage, and greatly reduces the failure rate. The application of strengthened cylinder liners and chrome-plated piston rings improves the durability of the engine and prolongs the life of the engine.

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