The Cummins CCEC NT855-C450 is a member of the NT855 series, known for its legendary reliability and rugged construction.

This inline six-cylinder engine is turbocharged and aftercooled, ensuring efficient combustion and improved power delivery. With a displacement of approximately 14 liters, the NT855-C450 can generate a maximum power output of around 450 horsepower (335 kW) at a rated speed of around 1800 revolutions per minute (RPM).

One of the standout features of the NT855-C450 is its electronic fuel injection system, which optimizes fuel delivery for improved efficiency and reduced emissions. This system enables precise control over fuel injection timing and quantity, resulting in better combustion and enhanced fuel economy. Additionally, the engine's advanced design incorporates a heavy-duty air-to-air intercooler, which cools the compressed air before entering the combustion chamber, leading to higher combustion efficiency and increased power output.

The engine's cooling system is designed to handle demanding conditions. It utilizes a liquid cooling mechanism, with a large capacity radiator and a powerful water pump to regulate temperature effectively. This ensures that the engine can operate within optimal temperature ranges even under heavy loads and high ambient temperatures, enhancing overall performance and durability.

To support its industrial applications, the NT855-C450 is built with a robust and durable construction.

The engine block is made from high-strength cast iron, designed to withstand the stresses of continuous operation. The crankshaft and connecting rods are forged for added strength and reliability. This rugged design not only contributes to the engine's longevity but also reduces maintenance requirements, making it suitable for various heavy-duty applications.

Maintenance is made convenient with features like easy access to service points, replaceable wet-type cylinder liners, and easily replaceable filters. The engine's modular design allows for efficient servicing, minimizing downtime and ensuring continuous operation.

The NT855-C450 is compliant with various emission standards, showcasing Cummins' commitment to environmental sustainability. Through advanced engineering and aftertreatment technologies, the engine manages to balance power output and emissions control effectively. This compliance with emission regulations makes it suitable for use in areas with stringent environmental standards.
