Key Technical Features of the NTA855-C250 Diesel Engine
Robust 14L Inline 6 Mechanical Diesel Platform
The NTA855-C250 is built on a 14L displacement inline 6-cylinder configuration, known for its mechanical simplicity and durability. Unlike electronically controlled engines, this mechanical diesel engine provides:
- Stable operation in harsh environments
- Easier maintenance and troubleshooting
- Lower dependency on electronic systems
This makes it especially suitable for remote job sites and export markets.
Cummins PT Fuel System for Reliable Fuel Delivery
A key feature of this engine is the Cummins PT fuel system, which ensures precise fuel delivery and efficient combustion. Compared to conventional injection systems, the PT system offers:
- Improved fuel atomisation
- Stable fuel pressure control
- Reduced maintenance complexity
This system contributes to consistent fuel consumption rates at full load, making the NTA855-C250 a cost-effective long-term solution.
Turbocharged and Aftercooled Performance
The turbocharged aftercooled design enhances engine efficiency and power density. Key benefits include:
- Increased air intake for better combustion
- Improved thermal efficiency
- Higher torque output at low speeds
With a rated speed of 2100 rpm and strong low-speed torque (up to 1017 N·m), the engine performs reliably in heavy-duty operations.
Key Applications: Why the CCEC NTA855-C250 for Construction Machinery is Unmatched
The versatility of the Cummins NTA855-C250 construction diesel engine allows it to power a diverse range of heavy equipment.
NTA855-C250 Engine for Bulldozer, Grader, and Roller
In the construction sector, the NTA855-C250 engine for bulldozer/grader/roller applications is prized for its "lugging" ability. When a bulldozer hits a heavy load, the NTA855-C250 1017N·m low-speed torque engine maintains power without stalling, a critical feature for Shantui and Liugong machinery.
Powering Mining Equipment and Drilling Rigs
For extraction industries, HekoPower recommends the NTA855-C250 engine for mining equipment. Whether used as a Cummins engine for drilling rig power units or in large-scale concrete mixers, the Euro II NTA855-C250 diesel engine meets emission standards while remaining easy to repair in the field.
Specialized Uses: Water Pumps and Fire Pump Units
The reliability of the diesel engine for water pump / fire pump applications cannot be overstated. The NTA855-C250 water-cooled turbocharged engine can run for extended durations at constant speeds, making it ideal for emergency standby systems and irrigation.
Comparison and Upgrading Logic
Comparison between NT855-C250 and NTA855-C250
The "A" signifies "Aftercooled." While the standard Cummins NT855-C250 diesel engine is reliable, the "NTA" version provides better thermal efficiency and higher power density.
NTA855-C250 vs NTA855-C280
If your application requires more "headroom," the C280 offers 30 more horsepower, but the 250HP Cummins NTA855 engine remains the most cost-effective solution for standard 20-ton class machinery.
The HekoPower Advantage: Genuine CCEC Original NTA855-C250 Engine
As a dedicated NT855-C250 engine supplier in China, HekoPower bridges the gap between factory production and global logistics.
Genuine Cummins Engine vs Rebuilt: Making the Right Choice
When searching for a Cummins NTA855-C250 price, many buyers are tempted by "rebuilt" options. However, a genuine CCEC original NTA855-C250 engine from HekoPower comes with a 12-month warranty and all-new internal components. Rebuilt engines often use mismatched parts that lead to premature failure in heavy duty low speed industrial engines.
Shipping Weight and Dimensions for Global Logistics
To assist our international clients, the genuine CCEC NTA855-C250 engine shipping weight and dimensions are roughly:
- Weight: ~1300kg (Dry)

Frequently Asked Questions (FAQ)
What is the difference between the NT855-C250 and the NTA855-C250?
The primary difference lies in the aspiration system. The "N" stands for naturally aspirated, "T" for turbocharged, and "A" for aftercooled. Therefore, the NT855-C250 is turbocharged, while the NTA855-C250 is both turbocharged and aftercooled. The aftercooler cools the compressed air from the turbocharger, increasing its density and allowing more oxygen into the combustion chamber, which results in more power and better efficiency.
What is the fuel consumption rate of the NTA855-C250 at full load?
Under full load at its rated speed, the NTA855-C250 typically has a fuel consumption rate of approximately 210-220 g/kW·h. Actual consumption will vary based on the specific application, load factor, and operating conditions.
Is this a genuine Cummins engine or a rebuilt unit?
HekoPower supplies 100% genuine, new CCEC NTA855-C250 engine assemblies. We are committed to providing our customers with original equipment that meets the highest quality standards.
Can this engine be used for an industrial generator?
Yes, the NTA855-C250 is an excellent choice for driving an industrial generator. Its stable 2100 RPM rated speed is well-suited for generating 50Hz or 60Hz power, depending on the alternator configuration.
