Advantages of N855-DM313 Marine Auxiliary Engine
- Robust Crankshaft and Piston Design – Witness the prowess of CCEC’s marine engines with a robust, fully balanced crankshaft design that ensures steady rotation and enhanced strength. The steel piston crown, equipped with oil galleries and aluminum skirts, stands as a testament to durability and minimal oil consumption, guaranteeing a reliable and efficient maritime journey.
- Precision Fuel Injection for Optimal Performance – Cummins’ unique PT system, featuring fixture and Step Timing control, propels fuel injection pressures beyond 120Mpa. This precision results in an outstanding fuel consumption rate and emission performance, setting a new standard for marine engine efficiency. The incorporation of a check valve in the fuel tube further enhances reliability in critical maritime operations.
- Enhanced Lubrication Efficiency – Experience a dual spin-on filter system that effectively separates impurities above 10um. Coupled with a low-pressure (240-310Kpa) and steady-temperature (100-120°C) lubricating oil system, CCEC minimizes auxiliary power wastage, ensuring optimal engine efficiency even in challenging maritime conditions.
- Cutting-Edge Cooling Technologies – CCEC’s commitment to excellence extends to the cooling system, featuring a great flux water pump and specialized channel design for effective heat dissipation. The inclusion of a spin-in water filter not only keeps the coolant clean but also maintains its acidity within normal limits, safeguarding engine health throughout the maritime journey.
