Key Details

  • Project Name: Marine Engine

  • Engine type: 6B 6C K19 K38 6L NTA855

  • Project Date: 6.8.2018

  • The Benefits:

  • Unmatched peformance driven through a perfectly matched turbocharger and a new 24-valve cylinder head that delivers industry-leading power density.

    Quiet operation, including an 80-percent reduction in noise at idle, is one of the many benefits from the common-rail fuel system.

    Enhanced sociability from the high-pressure common-rail design virtually eliminates smoke and improves the whole boating experience.

    Increased durability from innovative engine design characteristics.

    Maximize vessel performance and access comprehensive vessel diagnostic information via SmartCraft® electronics.

    Cummins offers a complete line of variable speed propulsion solutions designed specifically for the challenges of commercial, government and recreational marine applications. Our propulsion line includes the mechanical K and N Series and the electronic Quantum Series.

    Both the N Series and the K Series have proven reliable and durable in tough marine environments for over 25 years. Many of our NTA855 and KTA19/38/50 propulsion ratings are now certified to meet more stringent IMO Tier II global emissions standards.

Marine Propulsion

Both the N Series and the K Series have proven reliable and durable in tough marine environments for over 25 years. Many of our NTA855 and KTA19/38/50 propulsion ratings are now certified to meet more stringent IMO Tier II global emissions standards.

The Quantum Series product line was introduced in 2005 to meet the U.S. Environmental Protection Agency’s stringent Tier 2 emission standard. Today the product line is certified to current EPA, IMO and EU regulations and will serve as the platform for future more stringent standards.

Overview:

● Advanced design and sophisticated manufacturing Adapt to harsh working conditions, high strength, heavy load operation
● Holset wastegate valve is more dynamic
● Integrated design Cylinder, cylinder head and other parts “one multi-energy”, reducing the connection parts, parts are 40% less than other similar engines, the failure rate is greatly reduced
● Excellent reliability With forged steel camshaft and crankshaft, high-strength cylinder design, many parts are cast on the cylinder block, with high rigidity, high pressure resistance and long service life.
● The cylinder liner of the platform mesh honing design prevents the oil leakage with perfect geometric structure.
● Rotor high pressure fuel pump with lower fuel consumption and effective noise reduction
● Bosch inline fuel pump burns more under high injection pressure, less energy loss, stronger power, and strong fuel adaptability
● Extended stroke The combustion gas expands more fully, increasing the effective power output and ensuring low fuel consumption under strong power.
