Advanced Combat Engine offers better power density, lower heat rejection and improved fuel efficiency, Cummins claims.
Cummins has been awarded an $87 million contract by the US Army Ground Vehicle Systems Center to complete development of the modular and scalable Advanced Combat Engine (ACE).
The US manufacturer noted in a 30 July statement that ACE is a modular and scalable hybrid-capable diesel engine that employs opposed-piston technology to deliver 50% better power density, 20% lower heat rejection and 13% improved fuel efficiency.
An ACE powertrain can be configured with three, four or six cylinders to deliver 750-1,400hp.
‘ACE can be integrated into hybrid architectures, enabling commonality and ‘eliminating the expensive logistical burden of having multiple combat powertrains and facilitating the incorporation of new electrified technologies’, Cummins added.

UK hits pause on deployable mortar system procurement as US begins search
The US Army's market survey into available 81mm and 120mm mobile mortar systems was launched only a few days after the UK suspended Project Stokes, an almost identical plan, “pending future decisions on prioritisation, resourcing and funding”.
