Is the Opposed-Piston Engine Becoming More Real?
Achates Power has been working on its opposed-piston engine technology—which it claims is more cost effective than a traditional engine (thanks, in part, to the elimination of such things as a cylinder head and valve train), easier to produce, and potentially “approximately 50% more efficient than today’s gasoline engines” (the Achates engine runs on gasoline, diesel, natural gas. . .)—since 2004.

Piston Power for the U.S. Army
Although the future of the internal combustion engine seems to becoming completely shrouded in a haze of CO2 or NOx (OK, both of those are generally invisible, but you know what I mean), with everything going electric, there is still potential life in exploding gas, as indicated by last week’s announcement by Cummins Inc. that it has executed a $47.4-million contract to develop and demonstrate a technically advanced engine for the next-gen U.S. combat vehicles.

Are Two Strokes Better than Four?
A typical internal combustion engine at work in any car or truck today is a four-stroke: intake, compression, combustion, exhaust.
