Cummins KTA50-C1600 1600HP V16 Mining EngineProduct Description
The KTA50-C1600 is a 50.3-liter, 16-cylinder diesel engine in a 60° V configuration. Four-stroke. Turbocharged and aftercooled. PT fuel system with STC injection. Compression ratio 13.9:1. It was engineered specifically for machines that run continuous heavy-duty cycles; not the kind of workload where an engine gets to cool down between shifts.
If you've been searching for this engine and ended up with five different spec sheets showing five different torque figures, you're not imagining things. The KTA50-C1600 is calibrated differently depending on the application: mining haul truck configurations run at 2100 RPM, construction machinery variants at 1900 RPM, and genset builds at 1500–1800 RPM. Same engine block. Different ECU tuning and output curves. We'll make sure you get the correct configuration for your specific equipment — that's not a sales line, it's how this engine works.
Version Reference: The 2100 RPM / 5966 N·m spec is standard for mining truck applications (BELAZ, TEREX, Komatsu). If your equipment was originally spec'd at 1900 RPM or runs a genset load profile, tell us — the unit you need may be different. We stock both.
Every unit ships from the Chongqing Cummins plant (CCEC) with a factory test report, full operation and maintenance manual, and export-grade sea freight packaging.

Why the CCEC Plant — Not Just Made in China
Chongqing Cummins Engine Company (CCEC) was established in 1995 as a joint venture between Cummins Inc. USA and Chongqing Machinery & Electric. Cummins holds a 50% equity stake and contributes full technology transfer, engineering standards, and product line oversight. This is not a licensed copy or a domestic imitation. The CCEC plant manufactures under the same Cummins technical specifications as any other Cummins plant globally.
The KTA50 engine family was originally produced at Cummins' Daventry plant in the UK (DAV). CCEC produces the same engine family under direct Cummins technology and product line control. Both plants build to the same core specifications. The practical differences come down to price, lead time, and parts availability — all of which favor CCEC for export markets.
If you're sourcing a KTA50 for a mining operation in Africa, the Middle East, Central Asia, or South America, the CCEC version gives you a genuine Cummins engine at a more competitive price, with faster availability and better local parts support than waiting for a DAV-sourced unit.
CCEC vs. Cummins DAV
Most buyers searching for a KTA50-C1600 already have a machine with an existing engine; either an original DAV unit or an earlier CCEC unit . and they need a replacement or spare. The question they're really asking is: "Will this CCEC engine actually work in my machine?"
| Factor | CCEC (Chongqing, China) | DAV (Daventry, UK) |
|---|---|---|
| Cummins Technology | ✔ Full Cummins license | ✔ Original Cummins plant |
| Core Engine Design | Identical KTA50 architecture | Identical KTA50 architecture |
| Export Price | More competitive | Higher |
| Lead Time (to export markets) | ~15 business days | Longer, subject to availability |
| Parts Availability (Asia/Africa/ME) | Strong regional network | Limited direct channels |
| Drop-in Compatibility | Verified — see BELAZ case below | OEM standard |
| Documentation | Full test report + manual included | Standard OEM docs |

Field Verification: BELAZ 75131 Engine Replacement
BELAZ 75131 · Original DAV Engine → CCEC KTA50-C1600 Replacement
01 / Incident
A BELAZ 75131 mining dump truck sustained engine damage following an on-site accident. The original Cummins KTA50 unit, manufactured at the Daventry plant (DAV), was beyond repair.
02 / Decision
The operator needed a direct replacement. DAV-sourced units were not available within the required timeline. Our CCEC KTA50-C1600 was selected as the replacement.
03 / Adaptation
The replacement unit was modified and adjusted to precisely match the configuration profile of the customer's original engine — mounting points, output tuning, ancillary connections.
04 / Result
Post-installation, the engine operated flawlessly. Full performance was restored. The BELAZ 75131 returned to service delivering optimal output under standard mining load conditions.
What this confirms: A properly spec'd and adapted CCEC KTA50-C1600 is a viable, proven replacement for an original DAV KTA50 in a heavy mining haul truck. Cross-plant compatibility is real, not theoretical.
Where This Engine Works

All models: 4-stroke, V16, water-cooled, turbocharged and aftercooled, PT fuel system, Euro II / Non-road standard. The KTA50-C1600 torque range reflects different application configurations (mining 2100 RPM vs. genset 1500 RPM).
What Makes This Engine Suited for Heavy-Duty Work
1. Cummins PT Fuel System with STC Injection
The pressure-time (PT) fuel system controls injection based on fuel pressure and time — not a mechanical cam. It's simpler to maintain than common-rail systems, more tolerant of fuel quality variation in remote operations, and well-proven in extreme environments. STC (step timing control) adjusts injection timing under load, reducing smoke at startup and improving combustion efficiency at full load.
2. Turbocharged and Water-Air Aftercooled
Aftercooling drops the charge air temperature before it enters the cylinders. Cooler, denser air means more oxygen per combustion event — which is how you get 1600 HP out of a naturally-large but not impossibly-complex engine. It also reduces thermal stress on pistons and liners, which directly impacts overhaul intervals.
3. Replaceable Wet Cylinder Liners
When this engine needs a rebuild, you don't replace the block. Wet liners are designed to be swapped — which is why KTA50 engines can run for decades in mining operations without losing their service value. Lower rebuild cost, shorter downtime, longer total lifespan.
4. 223L Lube System / 45–118L Cooling Circuit
These aren't large numbers for marketing. They reflect the sustained thermal load this engine is designed to handle. A mining truck doesn't idle; it runs at 80–100% load for hours at a time in ambient temperatures that can push 45°C. The lube and cooling system capacity is sized for that reality.
5. Low-Profile Engine Design
The 60° V-angle produces a lower overall engine height compared to wider V-angle configurations. In mining truck installation envelopes where bonnet clearance is fixed, this matters.
Questions We Actually Get Asked
Can the CCEC KTA50-C1600 directly replace the original Cummins KTA50 from the DAV (Daventry) plant?
Yes — with proper configuration matching. The core engine architecture is identical across CCEC and DAV production. We have completed this exact replacement on a BELAZ 75131 dump truck. The process requires adapter and mounting adjustments to match the specific machine configuration, but there are no fundamental compatibility barriers. Contact us with your original engine serial and machine model and we'll confirm the adaptation scope.
Why do different sources show different torque figures for the KTA50-C1600?
Because they're measuring different things. The KTA50-C1600 is calibrated for different applications: at 2100 RPM (mining truck mode), max torque is 5,966 N·m at 1500 RPM. In genset configuration at 1500 RPM, torque rises to 7,300–7,600 N·m. Continuous prime power mode shows 5,071 N·m. The engine is the same — the output curve is different. If you need a specific torque figure for a machine spec, tell us the application and rated speed.
What is the fuel consumption of the KTA50-C1600 per hour in actual operation?
At rated power (1194 kW), specific fuel consumption is 210 g/kW·h. At full rated load, that translates to approximately 250 liters per hour (using standard diesel at ~0.83 kg/L density). Real-world consumption depends on load factor — a truck operating at 70% average load will consume significantly less. We can provide a fuel consumption curve across the RPM range on request.
What's the difference between the KTA50-C1600 and the KTTA50-C2000?
Power and cooling configuration. The KTA50-C1600 uses a single-stage turbocharger with water-air aftercooling (KTA = single A = water-air intercooler). The KTTA50-C2000 uses a two-stage turbo configuration with air-air intercooling (KTTA = double A), producing 2000 HP at 7,016 N·m. The KTTA series runs at higher boost pressures and is designed for applications requiring significantly more output from the same displacement.
What's the typical overhaul interval for this engine?
Under standard mining duty cycles with correct lubrication and maintenance intervals, KTA50 series engines are designed for major overhaul intervals of 10,000–15,000 hours. Actual interval depends heavily on operating conditions, fuel quality, and preventive maintenance compliance. The replaceable wet liner design is specifically intended to make overhauls cost-effective when they are required.
What's included in the shipment?
Standard supply includes: complete engine assembly, flywheel, alternator, factory test report, operation and maintenance manual, export packing for sea freight. Clutch assembly (SO60225 or SO60525) available separately or as part of power pack configuration. Spare parts kits — filters, injectors, pistons, gaskets — available on request. We can also supply the full power pack for direct drop-in replacement in mining truck applications.
