The NT855-C400 is engineered as a prime mover for a wide range of heavy-duty equipment, particularly excelling in three key sectors:
Construction & Mining Machinery: An ideal power source for demanding equipment such as excavators, bulldozers, wheel loaders, and mining haul trucks where high torque and reliability are critical.
Power Generation: Serves as a dependable driver for industrial and commercial generator sets, providing prime or standby power for facilities like factories, hospitals, and data centers.
Industrial & Marine: Powers large industrial pumps, compressors, crushers, and marine auxiliary systems requiring continuous, rugged performance.
1. Proven PT Fuel System for Ultimate Reliability
At its heart is the mechanical Cummins PT (Pressure-Time) fuel system. Renowned for its simplicity and robustness, this gear-driven system ensures precise fuel metering, excellent atomization, and stable operation even with varying fuel qualities, contributing to exceptional reliability and ease of maintenance.
2. Efficient Turbocharged and Aftercooled Design
The engine features turbocharging with air-to-air aftercooling (TTA). This technology forces a greater mass of cool, dense air into the cylinders, significantly boosting power output and combustion efficiency. The result is superior fuel economy, lower emissions, and reduced thermal stress on engine components.
3. Durable Construction for Extended Service Life
Built for longevity, it incorporates a heavy-duty cast-iron cylinder block and replaceable wet cylinder liners. This design allows for efficient heat dissipation and enables straightforward in-frame overhauls, extending the engine's operational life and reducing long-term ownership costs.
