Five cylinders, three spark plugs, three fuel injectors.

But when it is available what will it cost?And what wlll the horsepower be?Mileage?

The design reminds me of an A/C compressor.

Duke are not the first to build these. Of course, greed oil companies keep these things off the market because of their efficiency.

Interesting. The big advantage of a traditional ICE is it's virtually all linear motion translated directly to rotational motion.
The axial design has far more complex forms of motion. Looks more difficult to design, and I would think it would require more precise tolerances in manufacturing. It'll be interesting to see how this develops into larger power plants for larger and more powerful vehicles.

Good luck sealing that rotating joint at the head gasket. And while they're at it, good luck with durability on the ball and socket conrod big end.

It does look familiar, from long ago. it also looks like some hydraulic motors i have seen ( tho no combustion involved of course ). All of these designs have the same problem however, reciprocating motion.

If I remember correctly, another engine like this was built back in the 60s but, the swash plate would not handle the strain long enough to be considered a viable or reliable component on the engine. With out that swash plate, that engine is just a large paper weight. A large one I'll grant you but still useless.

Wikipedia has a good page on these type engines. One design was produced in 1911.

The 1969 Pontiac Fiero was to offer a similar radial engine in the trunk.

However was never produced. The car itself tho was sexy

That was my first thought.
There seem to be a number of small bearings in the design that are subjected to regular off center, if you will, loads if you noticed.
Unlike say, a Fiero engine).
Keeping them alive will be a major hurdle that they will need to get over.
I'm sure lubrication and durability are two of the major bugaboos that keep the engineers awake at night.
And like the Wankle/rotary, I'm wondering about fuel type and efficency....
Still, it's cool to see this being tried...
Thanks for posting this, Cliff.

That is amazing! An 18 cylinder engine that only weighs a couple of hundred pounds more than a dressed big block chevy. It's a shame that development did not continue.
