Overview :
373-597 kW | 500-800 hp
Power | Certification |
500 – 800 hp | IMO Tier II |
373 – 597 kW |
-
Designed to withstand the challenging conditions commercial marine operators often face; this same reliable, durable power is now available for recreational boating applications, including super yachts and yacht support vessels.
-
Improved idle stability and reduced noise and vibration are a direct result of the Cummins Modular Common Rail fuel system.
-
In-cylinder technology to meet IMO Tier II, EPA Tier 3 and EU Stg. 3a; platform for future emissions globally.
-
Covered by a comprehensive one year warranty and backed by Cummins global service network.
- Built at Seymour Engine Plant in Seymour, IN, U.S.
Features
-
Engine Design : Reliable base engine uses common components from the proven K19, K38 and K50 engines. A new cast-iron, ductile single-piece piston with nitride-coated rings and hardened cylinder liner provides excellent durability and long life.
-
Fuel System : Modular Common Rail Fuel System features a simplified design which provides constant high injection pressure regardless of engine speed or load condition. Benefits include low noise and vibration for quiet operation, idle stability and low-end torque.
-
Cooling System : Single-loop cooling eliminates the need for two keel coolers for reduced installation expense. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements.
-
Exhaust System : Water-cooled exhaust manifold cools engine surface temperatures. Design is a cast single piece construction that eliminates potential exhaust leakage.
-
Air System : Mounted or remote marine grade air cleaner with replaceable element reduces maintenance cost. Water-cooled turbocharger optimized for vessel operating conditions and safety.
-
Lubrication System : Standard capacity 60.6 L (16 U.S. gal) shallow oil pan or high capacity 72 L (19 U.S. gal) deep oil pan for installation flexibility. Cummins spin-on oil filters available on engine service side.
-
Electronics : 24v Quantum System electronics feature a proven CM850 ECM to monitor operating parameters, while providing diagnostics, prognostics and complete engine protection. Simplified electrical customer interface box for all vessel connections reduces installation complexity.
-
Certifications : Complies with IMO Tier II, EPA Tier 3 and EU Stage IIIa emissions regulations. Designed to meet International Association of Classification Societies (IACS) and SOLAS requirements. Consult your local Cummins professional for a complete listing of available class approvals.
