The NTA855-C360S10 is a 14-liter, inline six-cylinder, direct-injection diesel engine manufactured by Cummins, designed primarily for use in heavy-duty construction machinery. Its most widely recognized application is serving as the standard core power source for the Shantui SD32 crawler bulldozer.
Key specifications are as follows: Rated Power: 235 kW – 268 kW (320 hp – 360 hp)
Rated Speed: 1800 rpm / 2000 rpm / 2100 rpm
Max Torque: 1440 N·m – 1509 N·m (at 1400 rpm)
Displacement: 14.0 liters (14,010 ml) | Bore × Stroke: 140 mm × 152 mm
Intake System: Turbocharged and Aftercooled
Fuel System: Cummins' proprietary PT Pump direct-injection system
Net Weight: Approx. 1303 kg (Dry Weight)
Performance and Structural Features: High-Efficiency Fuel System: Utilizes the classic Cummins PT Pump direct-injection technology, ensuring excellent fuel atomization, strong adaptability to lower-quality fuels, and relatively lower maintenance costs. High-Strength Cylinder Block Design: The cylinder block is cast from high-strength alloy iron, offering superior rigidity, minimal vibration, and low noise levels; the large-diameter camshaft is capable of withstanding higher loads. Specialized Engineering Application: The "C" in the model designation typically signifies **Construction Machinery** usage; the design is specifically reinforced to deliver high torque at low speeds, enabling it to effectively handle the drastic load fluctuations inherent in bulldozer operations. Broad Compatibility: In addition to Shantui's mainstream models, this engine series is also commonly found in heavy-duty crawler bulldozers and drilling rigs manufactured by brands such as Zoomlion, Pengpu, and Shehwa
