Cummins
Legendary Heavy-Duty Power for the Toughest Applications
The Cummins NT855 series is the embodiment of industrial-grade power, durability, and dependability. Built on the legendary legacy of the Cummins 855 platform, this inline-six, 14-liter diesel engine is engineered to excel in the most demanding environments. Designed for extreme longevity and low total cost of ownership, the NT855 is a cornerstone for power generation, marine operations, and heavy-duty construction where mission-critical reliability is non-negotiable.
The NT855 series offers a range of configurations for diverse applications, from prime power generation to heavy machinery. Key specifications are summarized below:
The NT855 engine is engineered to deliver robust, continuous power across three major sectors:
Power Generation: The prime mover for industrial and commercial diesel generator sets, providing highly reliable prime or standby power for facilities, data centers, and critical infrastructure.
Marine Applications: A trusted power source for marine propulsion and auxiliary systems in workboats, fishing vessels, and commercial craft.
Heavy-Duty Industrial & Construction: The heart of demanding off-highway equipment, including heavy-duty trucks (historically), excavators, mining equipment, drilling rigs, and large pumps.
Legendary PT Fuel System: The NT855 utilizes Cummins' patented Pressure Time (PT) fuel system. This mechanically governed, high-pressure injection system ensures superior fuel atomization for efficient and complete combustion, contributing to the engine's renowned fuel economy and reliable, surge-free power.
Efficient Forced Induction: Equipped with Holset exhaust gas turbochargers, the engine maximizes air intake for greater power density and efficiency. Advanced models feature air-to-air or water-to-air aftercooling to cool the compressed intake air, further improving combustion efficiency, fuel economy, and emissions.
Proven "Big Cam" Heritage: The NT855 series descends from the iconic Cummins 855 "Big Cam" platform, known for its large-diameter camshaft design that enabled shorter, more efficient injection periods. This heritage translates into exceptional low-rpm torque production and million-mile durability potential, a reputation carried forward into the NT series.
Durable, Serviceable Design: Engineered for long life and easy maintenance, the NT855 features replaceable wet cylinder liners for excellent heat dissipation and straightforward overhaul. The robust construction with a heavy-duty cast-iron block and integrated design minimizes failure points and simplifies service in the field.
