OEM Cummins NTA855 diesel engine | Tonkee®

This Cummins engine employs a turbocharged and aftercooled system, enhancing its power output and fuel efficiency.

The turbocharger compresses incoming air, increasing the density and allowing for improved combustion. The aftercooler cools down the compressed air before it enters the engine, ensuring optimum air density and maximizing performance.

The NTA855 is capable of producing impressive power and torque figures. It delivers a power range of 250 to 400 horsepower (186 to 298 kilowatts) and a torque range of 895 to 1,500 lb-ft (1,213 to 2,034 Nm). These specifications make the NTA855 a suitable choice for demanding applications that require robust performance, such as heavy-duty trucks, construction equipment, and marine vessels.

Furthermore, the Cummins NTA855 engine features a reliable and efficient fuel system. It incorporates a high-pressure fuel injection system that ensures precise fuel delivery, resulting in improved combustion efficiency and reduced emissions. The engine is compatible with various fuel types, including diesel, biodiesel, and natural gas, providing versatility to meet different operational requirements and environmental regulations.

In terms of cooling, the NTA855 engine employs a liquid cooling system. It includes a radiator, water pump, and thermostat to maintain optimal operating temperatures. This cooling system enables the engine to withstand high ambient temperatures and heavy workloads while ensuring efficient performance and durability.

The NTA855 engine is also designed with serviceability in mind.

It features easily accessible components and maintenance points, facilitating routine inspections and servicing. The engine's modular design allows for efficient repairs and replacement of individual components, reducing downtime and maintenance costs.

The Cummins NTA855 has found widespread application across various industries. In the transportation sector, it powers heavy-duty trucks, buses, and emergency vehicles, delivering reliable performance for long-haul and stop-and-go operations. In the construction industry, it is utilized in equipment such as excavators, bulldozers, and loaders, providing the necessary power and torque to tackle demanding tasks. Additionally, the NTA855 is commonly employed in marine applications, serving as a propulsion engine for fishing boats, tugboats, and other vessels.
