Does it use AC or DC?

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?

[Reno89519]

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.

I thought they were talking about this:

well very much smaller. maybe they want to put one on each wheel :).

[ckilmer]

sounds like a wankel engine. there have been a lot of variations on this engine over the years.

[Sequoyah101]

Does not look scaleable.

[oil_dude]

Can you get 650 HP out of it, like a stock 4.4 Liter twin-turbo V8?

bump

[bigbob]

Where’s the plug?

[SC DOC]

Lots of Deficiencies and not scalable.

Man, Mario Faccioli could have used one of these back in the day.

[catnipman]

this thing looks incredibly complex and so difficult to repair that it would probably just be cheaper to melt it down and buy a new one ...

[stevio]

Awesome. Some really smart, creative people out there. More power to them.

Here's a fairly decent YouTube video presentation, but this guy seems like a rah-rah booster. He does a good job explaining how the mechanism works and has prepared some good animations.

This big problem that I see are the sliding valve seals. Rotating sleeve seals have always been the Achilles heel of many designs compared to poppet valves in a conventional ICE engine.

Liquid cooling would appear to be a serious challenge, too.

When I first saw this design I thought "the rotating mass will act as a flywheel eliminating the external flywheel." The narrator of this video makes that point.
