Opposed piston engines are getting to be the rage and this one, the CoAxe, from a company in Australia, looks like another interesting entry. It's initially being developed as a 100 horsepower unit for use in unmanned aerial vehicles.
The unit is relatively small, lightweight and low maintenance. It's also extremely low vibration since all moving parts have their opposite part moving in the reverse direction. They're not talking about use in motor vehicles and I wonder if the reason may be that it's better suited to continuous rpm operation, though you might think the shaft drive would fit the bill.
The video (no longer available) shows the idea in computer generated form along with see thru models for demonstrating the moving parts, but there's no actual engine, and like so many other similar projects, there may never be an engine.
You know, if even half of the concept engines we've covered here on The Kneeslider were to get built, we would be awash in new or revived designs. Take a run through our articles in the engines category and see what I mean.
Thanks for the tip, Joel.
