Cummins Engines

The Advanced Combat Engine (ACE) is ideal for new or repowered combat vehicles where mission effectiveness, maneuverability and survivability are key objects.

The compact 14.3L ACE produces 1,000 hp, and a peak torque of 2424 lb-ft. This four-cylinder, two-stroke, opposed-piston diesel engine is equipped with eight pistons, as well as supercharging and turbocharging capabilities that eliminate the necessity for a valve train. While compactness is a key advantage of ACE, particularly crucial for combat vehicles with their restricted installation space, the engine offers advanced capabilities not currently available. These include a 50% increase in power density, a 20% reduction in heat rejection, and a 13% improvement in fuel efficiency compared to today's best-in-class combat engines.
