KTA50-C1600
Cummins

The Cummins KTA50-C1600 is a premier 50-liter, V16 heavy-duty diesel engine engineered to deliver exceptional power density, legendary durability, and reliable performance in the world's most demanding operating environments. As a flagship model within the renowned Cummins K50 series, this 1600-horsepower engine is built for extreme-duty cycles in mining, heavy construction, and power generation, offering unparalleled torque and a robust design to maximize equipment uptime and productivity where failure is not an option.
| Feature | Specification |
|---|---|
| Engine Model | Cummins KTA50-C1600 |
| Configuration | 4-stroke, V-type 16 Cylinders |
| Displacement | 50.3 L |
| Rated Power | 1194 kW / 1600 HP @ 1900 RPM |
| Peak Torque | High torque output typical for the platform |
| Aspiration | Turbocharged & Aftercooled |
| Fuel System | Cummins PT Direct Injection |
| Dry Weight (Approx.) | ~3706 kg |
The KTA50-C1600 is engineered as the prime power source for the largest and most critical mobile and stationary equipment.
Mining & Heavy Haulage: The definitive power solution for ultra-class mining haul trucks (e.g., 150-ton to 240-ton class), large electric-drive wheel loaders, and drill rigs, built to withstand 24/7 operation in the harshest conditions.
Major Construction & Quarrying: Powers the largest excavators, bulldozers, and mobile crushers used in major earthmoving and infrastructure projects.
High-Capacity Power Generation: Serves as a dependable prime mover for large diesel generator sets providing prime or continuous power for mega-projects, industrial complexes, and utility support.
Marine Propulsion: A robust choice for large workboats, tugboats, and specialized vessels requiring high thrust and reliable propulsion.
1. Legendary K-Series Heavy-Duty Platform
Built on the proven and ultra-robust Cummins K-Series architecture, it features a high-strength cast-iron cylinder block and heads designed for maximum rigidity. Key durability features include replaceable wet cylinder liners for extended engine life and efficient heat transfer, and gallery-cooled pistons to manage extreme thermal loads, ensuring longevity under continuous high-power operation.
2. Advanced Turbocharged & Aftercooled Air System
The engine utilizes an advanced turbocharged and aftercooled (TTA) aspiration system. This technology forces a greater mass of cool, dense air into the combustion chambers, enabling complete fuel burn for maximum power output and efficiency while significantly reducing thermal stress on critical components.
3. Proven Cummins PT Fuel System
At its heart is the legendary Cummins PT (Pressure-Time) fuel system, renowned for its mechanical simplicity, ruggedness, and precise fuel delivery. This system ensures optimal combustion, excellent throttle response, and reliable operation even with varying fuel qualities, contributing to lower total operating costs and ease of maintenance in remote locations.
4. Engineered for Global Support and Simplified Service
Supported by Cummins' global service and parts network, the engine is designed for serviceability. It can be supplied as a complete "power pack" with integrated cooling and filtration systems, simplifying installation for OEMs and reducing downtime through planned maintenance programs.
