Sure is. Looks efficient, and wonder how the wear of parts might be.

The technology is shown here (http://www.regtech.com/rotaryprinciple.html)

     How much??
    My dad says that if you have to ask how much you cant afford it.


    Thanks Alot Mr Mom

VERY few moving parts. I especially like the HP to weight ratio.

A very interesting design and concept.  How many engines have been built to date?  Applications?  Wear statistics?

I think I got it - the cylinder walls move up and down while the pistons stay still - the rotors shape determining compression and exhaust - till you turbo or supercharge it   ;D

I do like that they allow it to be a diesel   :)

The principal looks simple enough but look at all the potential seal problems. Could be solved but expect it would take a bit of work.

Doesn't the Wankel Engine work similar to this and didn't it have seal problems when it first got started?

Wankel is really different.

  This one had problems, also. It has been upgraded since first one was built in 2001.

  Ran a 125 KW Genset, so, it must be getting reliable ??

Sure are a lot of seals. All 6 sides of each "cylinder wall" has to have a seal. And you have to wonder how they lubricate all of those sliding surfaces.
Cool to look at though. Lots of combustion strokes per revolution.

Thanks FDH, I try to keep up on new engine concepts. I thought I'd seen all the internal combustion engine designs. This one is new to me. I wonder about its efficiency?

I studied the gyro-recipicating engine about 28 years ago. I haven't been able to find anything on it since. Seems to have disappeared. Anybody got a link on it?

Here's another recent design that's supposed to hit the market sometime:How Quasiturbine Engines Work: Photo-detonation and Quasiturbine Engines (http://auto.howstuffworks.com/quasiturbine1.htm)

Looking through their website quite a bit and all I saw was a lot of promotional "news releases" and testing announcements. It's a great concept.  I would REALLY like to see some actual test results on this thing as far as actual performance and how the engineering team handled the moving vane seals. Some serious potential there for seal "blow by" I would think.

Anybody do a "Google" search on these guys?

That "Quasiturbine" seems really great !!

Wonder why it doesn't get into production faster ???

Here is a link to a chainsaw w/ the "Quasiturbine"
