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.

Features & Benefits

• Engine Design - Opposed piston architecture with 2-stroke design for high power density, improved power-to-volume ratio, high fuel efficiency and low heat rejection.
• Fuel System - Using a Modular Common Rail System, ACE is designed for operation in full-desert conditions across all specified military fuels (JP-8, JP-4, DF-1, DF-2, DF-A, F-24, HVO).
• Lubrication System - Integrated dry sump lubrication system with remote filtration enables ACE's low-profile engine design while maintaining engine efficiency.
• Air Intake System - Combining a Cummins HE500 variable geometry turbocharger with an integrated, gear-driven super charger, ACE minimizes transient response and maximizes performance.
• Exhaust System - Using thermally insulated exhaust manifolds and exhaust manifold elbows reduces surface temperatures and improves safety.
• Versatility - Although ACE is being developed for military applications such as the Next Generation Combat Vehicle, it can be used in commercial applications that also require high power with limited available space.
