Two-Stroke Opposed-Piston Diesel Engine By Achates Power The Achates Power opposed-piston engine is packed full of unique technology. The supercharged, turbocharged, diesel 3 cylinder makes use of six ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

In this video, we explore opposed piston engines, focusing on the Achates Power engine and the Asender engine. Opposed piston engines enhance the use of combustion energy by replacing the cylinder ...

Rudolph Diesel made tremendous progress in improving fuel efficiency by developing his diesel engine in the 1890s. Gasoline engines had been in development and commercial use for some years but were ...

An OP can be configured and packaged to fit the vehicle it’s intended for. For trucks, the cylinders are likely to be vertical or slanted. Photo: Achates Power Security’s tight at Achates Power Inc.

Argonne, which is partnering with Achates Power to develop a hydrogen-powered engine, recently began testing the engine in Argonne’s state-of-the-art facilities. In a groundbreaking demonstration, ...
