Advantages of CCEC KTA50-M2-1800 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.
