Features and Benefits
Engine Design: Reliable base engine uses common components from the proven K19, K38, and K50 engines. A new steel piston with PVD coating top ring along with nitride coated second ring and high boron liner provides the excellent durability and long life withstanding higher temperatures and meeting the stringent emission norms. No matter the vessel, Cummins will keep you always on.
Fuel System: Proven High Pressure Modular Common Rail Fuel System features an increased system pressure and optimized fueling. The pump is designed to give higher fuel pressure throughout the engine speed and load range. Benefits include low noise, low vibration for quiet operation, improved performance, idle stability and low-end torque while still delivering improved fuel economy.
Cooling System: Two-pump, two-loop, low temperature aftercooling maximizes efficiency and improves performance. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements. SOLAS Heats shields meet Subchapter M requirements.
Exhaust System: Dry exhaust manifold and turbocharger deliver improved transient response. Vertical or horizontal exhaust connections available for installation flexibility. Compact SCR designed to meet the rigors of the marine environment. The system has been designed with integrated System Out NOx sensors, DEF dosing units, Internal Decomp tubes all working together to give the customer optimized DEF consumption. The Exhaust Throttle Valve integrated with the engine enables for an efficient SCR cleaning allowing the customer to operate transparently to previous non-SCR products.
Air System: Turbocharger is a standard Cummins offering working in tandem with an engine integrated wastegate that allows for precise air flow management and enhanced transient response. Mounted or remote marine grade air cleaner options are available. The air system design provides a significant increase in power for the continuous operating rating definition.
Lubrication System: Standard capacity 114 L (30 gal) and high capacity 166 L (44 gal) marine grade oil pan. Cummins spin-on oil filters available for easy accessibility and servicing. Optional “service free” integral breather system eliminates oil carryover for a clean bilge.
Electronics: 24v Quantum System electronics feature an ECM to monitor operating parameters, while providing diagnostics for complete engine protection. Simplified electrical customer interface box for all vessel connections to reduce installation complexity.
Certifications: Complies with IMO Tier III and EPA Tier 4 emissions regulations. Designed to meet the International Association of Classification Societies (IACS) and SOLAS requirements. Consult your local Cummins professional for a complete listing of available approvals.
