Does it use AC or DC?
ICE....................
Very cool design but you cannot add more pistons inline, so you’re going to have to increase your mechanical systems and/or the equivalent to you crankshaft or transfer cases if you want more cylinders.
I would say that is better candidate as the gasoline side power source for electrical generation in a gas-electric hybrid than it is for mechanical force generation in a gas-only vehicle.
Pretty cute, sending link to my friend Tom to figure out where to put the turbos...

Seriously, though, what practical uses, especially once it gets all of the emissions components added? And how noisy? Will it run a generator? Put in trunk of Tesla to recharge it on the road?
Package and sell it as a build your own engine, especially tied to a generator. That looks like it would be a fun and challenging kit build.
I just dont see the advantage of this thing.
Compare the parts count of a one cylinder engine to what is in this engine.
well very much smaller. maybe they want to put one on each wheel :).
sounds like a wankel engine. there have been a lot of variations on this engine over the years.
“sounds like a wankel engine.”
Not even close. This uses the typical 4-stroke piston.
Does not look scaleable.
There are several of these Internal Combustion engines that are small, light, and power dense for their size, but not really scalable to larger engines. And they're incredibly expensive to manufacture. LiquidPiston is another.
The anticipated use for these small, light, and powerful engines is to power military drones.
Good point. If I understand you correctly, we’re essentially talking about somehow adding multiple engines as a way to increase output. OR...making the same thing but bigger. I can see a decreasing weight to output curve on that idea, though. Maybe the same with the former.
Then again, in the video they talk about using a scale large enough to drive cargo ships and trains. Hmmm...
Am also wondering, what exactly are the emissions? Does it/will it need a catalytic converter and if so, how much HP will it rob?
If it really is great, I’m sure the government will figure out a way to F it up.
Go to the article’s site and look at the video. It’s little like a Wankel.
“I just dont see the advantage of this thing”
Weight is one. I think the article said it weighs around 1/3 of the Honda GX-240 engine used in lawn equipment and has higher output also. What they end up doing with the valve train design is going to be make or break — rotary valve or what. Again, from memory, I believe the prototype rotary valve design had insurmountable flow problems but my 1968 Yamaha 100 thought it flowed fine, just fixed timing.
“It’s little like a Wankel”
It looks like a Wankel inside a differential.
