IHave a Jeep YJ that would benefit fron installing an appropriately sized TD.
Aviation could use an engine like this. I see them as an early adopter, plus the simplicity may mean more time between overhauls.
The other use would be standby generators. They are noisy and heavy now.
Not unlike an older GM A/C compressor.
The wear between the head and the cylinders will kill it.
How is a swash plate inefficient? If it does not produce heat, and I cannot imagine that it does, or at least not much, how is it robbing power?
Low surface to volume helps, but makes for something somewhat outsized.
It’s only 29 feet long and 15 feet tall......................
Is it 4 cycle, ie: suck,squeeze, bang, and blow or something different?
They put the Dyna-cam engine in an aircraft over thirty years ago.
Hadn't heard much about it since.
Another unique design that’s been around for a while:

Interesting stuff. Reminds me of the excitement generated by the Wankel back in the day, before the first Arab Oil Crisis.
Then, one of the Wankel’s biggest shortcomings turned out to be its relatively-poor MPG.
And, since this article doesn’t tout the Duke Axial Engine’s fuel efficiency, I’m guessing it’ll go nowhere in today’s (Nanny State skewed) marketplace... unless those promised “future developments” bear substantial fruit.
“Is it 4 cycle, ie: suck,squeeze, bang, and blow or something different?”
Per the company, it is a four-stroke engine.
It is basically an axial piston hydraulic pump / motor with spark plugs and a fuel injection system.
and a variable compression ratio design..................
Some where I have a swash plate compressed air motor I built. Converted it to steam and got about 4 amps at 12 volts out of it.
One of my personal favorites is the Knight sleeve-valve motor:

This is a swashplate engine, which has been done before. People have tried most of this technology. Not saying this isn’t the Holy Grail, just saying I ain’t holding my breath.
“The estimate is that it’s probably a process of a couple years to get it to production ready,”
Multiply by five, at least.
