Cummins KTA50-C1600 1600HP V16 Mining Diesel Engine

The Cummins KTA50-C1600 is a 50.3L V16 heavy-duty diesel engine developed for mining haul trucks, large drilling equipment, industrial power packs and other applications operating under prolonged high load. In the referenced mining-truck configuration, it is rated at 1,194 kW / 1,600 HP at 2,100 RPM and develops approximately 5,966 N·m at 1,500 RPM.

The KTA50-C1600 uses the Cummins PT fuel system with STC timing control, turbocharging and water-to-air aftercooling. Its large lubrication and cooling capacities, replaceable wet cylinder liners and heavy-duty V16 architecture make it suitable for equipment that works through long shifts with limited opportunity to cool down.

KTA50-C1600 engines are available in different application calibrations. A mining-truck engine rated at 2,100 RPM is not automatically interchangeable with a 1,900 RPM construction configuration or a 1,500–1,800 RPM generator configuration, even when the base model name appears similar.

Confirm the Correct KTA50-C1600 Configuration Before Ordering

The model name KTA50-C1600 does not identify every installation detail. Engines used in mining trucks, construction equipment, industrial power packs and generator sets can differ in rated speed, torque curve, governor setting, cooling package, flywheel housing, alternator, exhaust layout and accessory arrangement.

For CCEC-to-DAV or DAV-to-CCEC replacement projects, the base KTA50 architecture may be compatible, but the final installation still requires configuration verification and may require changes to mounting, connections, accessories or output settings.

Cummins KTA50-C1600 Technical Specifications

Core Engine Data

Mining-Truck Performance Data

The following data applies to the referenced 2,100 RPM mining-truck configuration. It should not be automatically applied to construction-machinery or generator versions.

At 1,194 kW and 210 g/kW·h, calculated full-load fuel use is approximately 251 kg per hour. Using a reference diesel density of 0.83 kg/L, this is approximately 302 litres per hour. Actual fuel consumption depends on load factor, altitude, ambient temperature, fuel density and engine condition.

Lubrication, Cooling and Electrical Data

Dimensions, Weight and Installation Data

The different weight figures describe different engine conditions and accessory packages. The installation drawing and lifting plan should use the weight corresponding to the actual supplied configuration rather than the lowest listed dry weight.

Why Rated Speed Changes the Engine You Need

The KTA50-C1600 is used across several duty profiles. The same 50.3L base architecture can be configured with different rated speeds, output curves and supporting systems.

A 7,300–7,600 N·m figure found on some KTA50-C1600 listings may refer to a lower-speed industrial or generator configuration. It should not be used as the torque specification for the referenced 2,100 RPM mining-truck version without reviewing the original performance curve.

Typical KTA50-C1600 Applications

References to BELAZ, Terex, Komatsu and other equipment families should be treated as application examples. Direct installation must be confirmed by machine model, original engine data and installation drawings.

CCEC and DAV KTA50 Replacement Compatibility

CCEC and DAV engines can share the same KTA50 base architecture, but manufacturing location alone does not determine whether one unit can replace another. Compatibility depends on the exact build specification and application package.

A replacement may require bracket modification, connection changes, accessory transfer or output adjustment. The engine should therefore be sold as a configuration-matched replacement rather than a universally guaranteed drop-in unit.

Project Reference: BELAZ 75131 Engine Replacement

In the supplied project reference, a BELAZ 75131 mining truck required replacement of a damaged DAV-produced KTA50 engine. A CCEC KTA50-C1600 was selected because a DAV replacement was not available within the project schedule.

The replacement engine was adjusted to match the original machine’s mounting, output setting and ancillary connections. After installation and commissioning, the truck returned to operation under its normal mining load.

This project demonstrates that cross-plant replacement can be practical when the engine is configured and adapted to the original machine. It should not be interpreted as proof that every CCEC KTA50-C1600 can replace every DAV KTA50 without technical review.

KTA50-C Series Model Comparison

The KTA50-C family covers several output levels on the 50.3L V16 platform. The figures below are general comparison references and must not replace model-specific technical documentation.

Model selection must also consider cooling capacity, transmission limits, duty cycle, altitude, emissions requirements and installation envelope. A higher-power KTA50 variant is not automatically an upgrade for an existing machine.

Heavy-Duty Design Features

Cummins PT Fuel System with STC

The PT system meters fuel according to supply pressure and injection timing. Its mechanically actuated injectors and relatively straightforward fuel architecture are widely used in heavy-duty K-series engines. STC adjusts injection timing according to operating conditions to support starting, smoke control and loaded combustion.

Turbocharging and Water-to-Air Aftercooling

The aftercooler reduces compressed-air temperature before the air enters the cylinders. Denser intake air supports high output while helping control combustion and component temperatures under sustained load.

Replaceable Wet Cylinder Liners

Wet liners allow the cylinder surfaces to be replaced during overhaul without replacing the complete block. This supports rebuildability and long-term service value in mining operations where engine replacement and downtime are expensive.

Large Lubrication and Cooling Capacity

The large oil and coolant volumes reflect the thermal load of a 50.3L engine operating for long periods at high output. Final oil and coolant quantities must follow the actual sump, radiator and installation configuration supplied with the engine.

60-Degree V16 Layout

The 60-degree V arrangement provides a relatively compact width and height for a V16 engine. Overall dimensions, maintenance access and centre-of-gravity loading must still be checked against the machine installation drawing.

Frequently Asked Questions

Can a CCEC KTA50-C1600 replace a DAV-produced KTA50?

It may be used as a replacement when the base architecture and application configuration are matched. Engine mounts, flywheel housing, rated speed, output curve, cooling connections, electrical system and accessories must be checked. Some projects require adaptation rather than a direct installation.

Why do KTA50-C1600 torque figures vary between suppliers?

Different figures may refer to different rated speeds and applications. The referenced mining configuration produces approximately 5,966 N·m at 1,500 RPM, while lower-speed industrial or generator configurations may show higher torque. The correct figure must come from the performance curve for the exact engine build.

How much fuel does the engine use at full load?

Using the referenced value of 210 g/kW·h at 1,194 kW, calculated full-load consumption is approximately 251 kg/h, or around 302 L/h at a diesel density of 0.83 kg/L. Actual consumption is normally lower when average load is below 100%.

What is the difference between KTA50 and KTTA50?

KTTA models generally use a different turbocharging arrangement and are configured for higher output. The exact difference depends on the model and application, so turbocharger layout, aftercooling system, rated power and technical documentation should be compared before replacement.

What is the expected overhaul interval?

Overhaul timing depends on load factor, maintenance, oil condition, fuel quality, cooling performance, ambient dust and operator practices. A fixed 10,000–15,000-hour interval should be treated as a planning reference rather than a guaranteed service life.

What is normally included with the engine?

The standard scope may include the complete engine, flywheel, starter, alternator, factory test information, operation documentation and export packing. The exact accessory list must be written into the quotation because radiator, clutch, control system and power-pack equipment may be optional.

What information is required for a quotation?

Provide the machine model, engine nameplate, ESN, current rated speed, required power, original engine photos, flywheel-housing information, required accessories, quantity and destination.
