The family of engines strategy uses a common power cylinder system across several different engine variants to address a range of power and torque requirements in order to serve multiple military vehicles with a common architecture. In December 2020, Achates Power announced that their 10.6L

The engine was invented by Herns Louis, veteran of more than 30 years in the parts manufacturing industry ranging from automotive to aerospace, specializing in computerized parts machining. The technology can be easily adapted to existing engines, making the implementation very cost effective.

The HPE was long thought to be a system in which all engine valves had to be actuated in a fully variable manner to allow for two-stoke pneumatic modes and still enable the four-stroke combustion mode. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.

The Libralato engine is a rotary engine comprising two interlaced circular chambers of slightly different diameters. The Libralato engine has only four moving parts which perform the four phases in every revolution of the engine. The rotors do not rely on casing contact for their location as in Wankel engines.

An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. Using the pressure from the exhaust gas from the active cylinders, the ‘idle’ cylinders could be expanded to extract more work out of the engine during partial load operation.

Combustion starts in the central part of the channel, where the fuel/air mixture is rich and flame propagates to inner and outer end of the cell. Since heat release increases pressure inside the channel, opening the outer channel end generates an outflow of the exhaust gases. The air-fuel mixture can be radially stratified.
