Understanding the Advanced Combat Engine (ACE)
The Advanced Combat Engine (ACE) is a revolutionary engine designed by Cummins in collaboration with Achates Power. The key feature of the ACE is its opposed piston technology, which allows for increased efficiency and power output. This engine stands out due to its unique configuration—containing only four cylinders, yet capable of producing 1,000 horsepower.
The Technology Behind the ACE
The opposed piston design involves two pistons per cylinder that move toward each other, creating compression without the need for a traditional cylinder head. This allows for better thermal efficiency and reduces the risk of heat loss, a significant advantage in military applications where reliability is paramount. The engine’s two crankshafts must be precisely geared, adding to the complexity but also the benefits of this innovative design.
Applications of the 1,000 Horsepower Diesel Engine
The primary application of the 1,000 horsepower diesel engine is within military vehicles, particularly those requiring high power in a compact form factor. The U.S. Army awarded Cummins an $87 million contract for the ACE, recognizing the need for advanced powerplants in next-generation armored vehicles.
Military Vehicles
Military applications demand engines that offer both power and reliability. The ACE is designed to power tanks and infantry vehicles, providing the necessary performance to operate in challenging environments. Its compact size—31 inches in length and 23 inches in height—makes it suitable for confined engine bays typical in military vehicles.
Other Potential Uses
While the ACE is primarily aimed at military applications, its technology could be adapted for commercial use in areas requiring high output but limited space, such as in certain types of heavy machinery or specialized vehicles. Moreover, the principles behind opposed piston engines can potentially lead to innovations in civilian diesel applications.

Benefits of Opposed Piston Technology
The opposed piston technology utilized in the ACE engine provides several benefits that enhance its performance and efficiency:
Enhanced Efficiency
By eliminating the need for a traditional cylinder head, the engine can achieve higher thermal efficiency. This results in better fuel economy and reduced emissions, aligning with modern military requirements for sustainability.
Compact Design
The compact nature of the opposed piston design allows for a more efficient use of space in the engine bay. This is critical for military vehicles, which often have limited room for engine installations.
High Power Output
The design allows for a significant increase in power output without proportionately increasing the size or weight of the engine. This enables military vehicles to carry heavy loads or execute high-performance maneuvers with ease.
Challenges in Opposed Piston Engine Design
While the advantages are clear, opposed piston engines also face unique challenges that engineers must address:
Complexity of Design
The dual crankshaft setup requires precise engineering and robust materials to ensure reliability. Balancing the engine can also be more complicated compared to traditional designs.
Maintenance Considerations
The unique design may lead to different maintenance requirements, which military technicians must adapt to when servicing these engines in the field.
