600 HP Cummins KTA19-M3 marine engine, four-stroke inline 6-cylinder design
Cylinder block strengthening: high-strength vermicular graphite iron (CGI) cylinder block, with a tensile strength of 450 MPa, 60% higher than traditional gray cast iron, and a cylinder diameter × stroke of 159 mm × 159 mm, achieving optimized power density at 19L displacement.
Breakthrough in materials and manufacturing processes
Piston anti-wear technology: A 300 μm thick plasma ceramic layer (Al2O3-13%TiO2) is sprayed on the top of the aluminum alloy piston, and a nickel-based alloy bushing is cast in the ring groove, with a wear rate of <0.005 mm/1000h.
Valve strengthening: The intake valve is laser-clad with Stellite alloy using 21-4N steel, and the exhaust valve is vacuum-infiltrated with nickel-based high-temperature alloy (Inconel 751), with temperature resistance increased to 850℃.
600 HP Cummins KTA19-M3 Marine Engine Features:
Integrated design: The cylinder block and cylinder head adopt an integrated design to reduce the risk of water and oil leakage and minimize the failure rate.
Enhanced durability: The reinforced cylinder liner and chrome-plated piston ring help improve the durability of the engine and extend its service life.
Emission compliance: The engine meets the requirements of China Inland River No. 1, China Inland River No. 2 and IMO TIER2 stage emission regulations. It uses CMI's BHT3B supercharger optimized for marine engines, which helps to reduce emissions and improve reliability.
Fuel efficiency: High injection pressure, overspeed protection, low-pressure fuel supply, and optimized pipeline design ensure full fuel combustion and high efficiency and energy saving. Equipped with ESTC electronic oil level timing control valve, it accurately supplements and adjusts the timing and improves the combustion smoke color at low idle speed.
Reasonable exhaust system design: The exhaust system of Chongqing CSSC marine engine is reasonably designed, and the water-cooled supercharger and water-cooled exhaust pipe effectively reduce the engine surface temperature to meet SOLAS safety regulations.
