KTA38-C1050
Cummins

The Cummins KTA38-C1050 is a premier 38-liter, V12 heavy-duty diesel engine designed to deliver exceptional power, legendary durability, and reliable performance in the most demanding operating environments. Engineered for extreme-duty cycles in construction, mining, and industrial sectors, this 1050-horsepower engine offers unparalleled torque and a robust design to maximize equipment uptime and productivity.
The table below summarizes the key technical specifications of the KTA38-C1050 engine.
The KTA38-C1050 is engineered as the prime power source for heavy machinery and equipment where high power density and continuous operation under load are critical.
Construction & Earthmoving Machinery: Excels as the driving force for large excavators, bulldozers, graders, and heavy-duty dump trucks used in major infrastructure projects.
Mining Equipment: A reliable and robust power solution for mining haul trucks, large wheel loaders, and drill rigs, built to withstand 24/7 operation in harsh conditions.
Specialized Heavy Vehicles: Powers crane carriers, concrete pump trucks, and oilfield service rigs that demand high torque and stable power output.
Industrial & Power Generation: Serves as a dependable prime mover for high-capacity industrial pumps and large diesel generator sets for prime or continuous power.
1. Proven Turbocharged & Aftercooled Air System
The engine features an advanced turbocharged and aftercooled (TTA) aspiration system. This technology forces a greater mass of cool, dense air into the combustion chambers, enabling more complete fuel burn for maximum power output and efficiency while reducing thermal stress on components.
2. Robust and Durable Engine Platform
Built on the proven K-Series architecture, it incorporates heavy-duty design features for longevity. Key elements include replaceable wet cylinder liners for extended engine life and lower rebuild costs, and gallery-cooled pistons for maximum durability under continuous high load. Its high-strength construction is designed to withstand the intense vibrations and shock loads of heavy equipment operation.
3. Reliable Cummins PT Fuel System
At its heart is the legendary Cummins PT (Pressure-Time) fuel system, known 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.
4. Engineered for Simplified Service and Support
The engine is designed with serviceability in mind, supported by a global Cummins service network. Available as a complete "power pack" including radiator, air filter, and chassis, it simplifies installation and integration into OEM equipment.
