Cummins Marine KTA19-M3 640 HP advantages

  • The cylinder block is integrated with the cylinder head, which reduces failure rates and prevents oil and water leakage. The use of chrome-plated piston rings and strengthened cylinder liners improves durability and extends engine life.
  • The supercharger is optimized for marine engines and meets all the emission requirements for China Inland River 1, China Inland River 2, and IMO Tier2 regulations. It reduces emissions and improves engine reliability.
  • It can achieve energy savings with high efficiency and high-injection pressure. The ESTC electronic timing control valve equipped with the valve can be used to accurately adjust and supplement the timing, and improve the color of the combustion smoke at low idle speeds.
  • The exhaust system design of the Chongqing CMI Marine Engine is reasonable. Water-cooled superchargers and water-cooled pipes can reduce the surface temperatures of the engine to meet SOLAS safety requirements.
