The Komatsu-Cummins N-855 is a heavy-duty diesel engine developed as a collaboration between Komatsu Ltd., a Japanese multinational corporation, and Cummins Inc., an American corporation specializing in power solutions. The N-855 engine is based on the Cummins N855 series, which has been widely used in various applications such as construction equipment, trucks, and industrial machinery.
Here are some key features and specifications of the Komatsu-Cummins N-855 engine:
Displacement: The N-855 engine has a displacement of 14 liters (855 cubic inches), which is where it gets its name.
Configuration: It is an inline 6-cylinder engine, meaning it has six cylinders arranged in a straight line.
Power Output: The power output of the N-855 engine can vary depending on the specific model and application. It is available in a range of horsepower ratings, typically from around 240 horsepower to 450 horsepower.
Turbocharged: The N-855 engine utilizes turbocharging to increase its power and efficiency. Turbocharging involves using a turbine-driven compressor to force more air into the engine, resulting in improved combustion and higher power output.
Fuel System: The N-855 engine uses a mechanical fuel injection system, which delivers fuel directly into the cylinders at high pressure for efficient combustion.
Cooling System: It features an efficient liquid cooling system to regulate the engine’s temperature during operation.
Applications: The N-855 engine is commonly used in a variety of heavy-duty applications, including construction machinery such as bulldozers, excavators, and loaders, as well as in trucks, generators, and other industrial equipment.
It’s worth noting that while the Komatsu-Cummins N-855 is a collaborative product, the N855 series is primarily associated with Cummins. However, Komatsu and Cummins have collaborated on various projects, and their partnership has resulted in engines specifically designed to meet the requirements of Komatsu equipment.
