Publicly available information is insufficient here to confirm the full extent of its product commercialization, current operating status, or principal customers.

Achates Power was established in the United States in 2004 with a focus on opposed-piston engine technology. The architecture places two opposing pistons in a shared cylinder, removing some components associated with a conventional cylinder-head design and changing the arrangement of the combustion chamber, gas exchange, and cooling systems. The company has publicly positioned the technology for applications such as commercial and military vehicles, emphasizing fuel efficiency, power density, and emissions performance. Because the verifiable public record available here is limited, this entry does not add unconfirmed executives, specific engine model names, production dates, or later operating developments.
