The NTAA855-C360S20 is designed as a prime power source for heavy machinery and equipment requiring dependable power in challenging conditions. Its primary applications include:
Heavy Construction & Mining: Powers large excavators, bulldozers, wheel loaders, and mining support equipment where high torque and resilience are critical.
Power Generation: Serves as a reliable driver for industrial generator sets, providing prime or standby power for remote sites, plants, and critical facilities.
Industrial Drives: Ideal for high-capacity pumps, compressors, and crushers in continuous, heavy-duty industrial processes.
Marine & Specialized Applications: Used in marine auxiliary power and other demanding equipment.
Advanced Turbocharged & Aftercooled Design
The engine features an efficient turbocharged and aftercooled (TTA) aspiration system. This technology forces a greater mass of cool, dense air into the cylinders, significantly increasing power output and improving combustion efficiency for superior fuel economy and performance.
High-Pressure Fuel System for Optimal Combustion
Utilizing an advanced high-pressure direct injection fuel system, the engine ensures precise fuel delivery and excellent atomization. This results in cleaner, more complete combustion, contributing to strong power output, improved fuel efficiency, and lower emissions.
Proven Durable Construction
Built on the renowned heavy-duty 855 series platform, it incorporates a rugged cast-iron cylinder block and durable components designed to withstand high cylinder pressures and thermal loads. This robust construction ensures extended service life and reliability in severe operating conditions.
