Advantages of KTA19-M425 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.
