Key Features of Cummins NTA855-DM317 Marine Diesel Engine
14L 6-Cylinder Turbocharged Aftercooled Design
The CCEC NTA855‑DM317 turbocharged aftercooled engine adopts Cummins’ patented turbocharging and air‑to‑air aftercooling system, greatly improving combustion efficiency and power density. Its 14L large displacement ensures strong low‑speed torque and excellent durability under long‑term marine working conditions. Equipped with a Cummins PT fuel system and integrated heat exchanger, the engine achieves compact structure and stable heat dissipation for marine environments.
317KW 1500RPM Rated Performance
As a standard 317KW 1500RPM marine diesel engine, the NTA855-DM317 is specially calibrated for generator drive. It provides consistent frequency and voltage output for shipboard electricity generation, making it an ideal Cummins NTA855-DM317 marine generator engine and CCEC NTA855-DM317 auxiliary diesel engine.
CCS IMO Approved for Marine Vessels
The Cummins NTA855-DM317 holds complete CCS IMO certification and meets strict marine emission and safety standards. Our NTA855-DM317 CCS IMO Tier II certification details include formal test reports, factory certificates, and inspection records, fully compliant with requirements for international navigation vessels. This certification makes the engine widely applicable for commercial fishing vessels, cargo ships, and offshore platform power systems.
Fuel Consumption Curve at 1500rpm
The optimized fuel injection map gives the NTA855-DM317 fuel consumption curve at 1500rpm obvious advantages in partial load conditions, reducing operating costs for long‑term marine use. With good cold-start performance, it supports reliable start at ‑12℃, suitable for various marine climates.
Typical Applications of NTA855-DM317 Marine Auxiliary Engine
The Cummins NTA855-DM317 marine generator engine is designed for a wide range of marine auxiliary power scenarios:
- Cargo ship onboard electricity generation systems
- Offshore platform generator power units
- Commercial fishing vessel genset systems
- Marine diesel generator sets operating at 1500RPM
- Ship auxiliary power system diesel engine integration
Comparison: NTA855-DM317 vs. NTA855-M400 and DM287
When selecting a power unit, it is important to note the difference between Cummins NTA855-DM317 and NTA855-M400. While the M400 is often rated for propulsion, the DM317 is a dedicated NTA855 generator drive. Furthermore, the NTA855-DM317 vs NTA855-DM287 comparison shows that the DM317 offers a higher power ceiling for vessels requiring more significant auxiliary loads, such as large commercial fishing vessels or cargo ships.
