Key Features & Technical Advantages of NTA855-M400
298kW 400HP High Performance & Low Fuel Consumption
The Cummins NTA855-M400 marine engine provides stable 298kW output and optimized fuel efficiency as low as ≤220g/kW·hr. Its Holset HT3B turbocharger and advanced fuel injection system ensure strong low‑speed torque and smooth operation. This makes the Cummins 400HP marine diesel engine ideal for long‑distance shipping and continuous propulsion duty.
IMO Tier II & CCS Certified Marine Engine
As a strictly regulated IMO certified marine diesel engine, the NTA855-M400 IMO Tier II version complies with international marine emission regulations. It also carries CCS certification, which is essential for vessel registration and inspection. HekoPower supplies fully certified CCEC NTA855-M400 marine propulsion engine units ready for direct installation.
Robust Design for Harsh Marine Environments
The NTA855-M400 features a sea water pump and heat exchanger cooling system, water‑cooled exhaust manifold, and prelub system for dry‑start protection. It supports reliable starting at temperatures as low as -12℃, with a dry net weight of 1430kg and overall dimensions 1809×881×1598mm for convenient engine room planning. Equipped with Fleetguard spin‑on oil filters and 24V/100AMP electrical starting, the engine reduces maintenance difficulty and improves durability.
Applications of Cummins NTA855-M400 Marine Engine
Fishing Boats, Tug Boats & Cargo Ships
The NTA855 marine engine is widely used for fishing boat 400HP propulsion, tug boat propulsion, and cargo ship propulsion.
