RE: is this better engine?

Huge surface area on the combustion chambers...

What did you used to see in circuses, eating fish, and balancing balls on their noses?

SEALS! :D

RE: is this better engine?

Rotaries have some really neat features that are theoretically possible - often vastly oversold by the marketing guys. However, physically realizing them is a different matter. Also, durability is almost always a game stopper for these engines.

RE: is this better engine?

My view (!) Rotaries of all types are emulating gas turbines.  Massive power to weight ratio; average/bad economy.

RE: is this better engine?

you'd wear out the sides of those plates before too long, since they must react the cylinder pressure during firing by "wedging" themselves against the opposing sides of the channels in which they slide.  This is, in essence, a mucked-up and less-workable version of a swashplate engine.

RE: is this better engine?

Have had experience with using a vane pump as a motor.  Vane wear (for heavy steel vanes) and breakage (for lightweight carbon vanes) is an issue, especially in hot, sooty environment; fouling of the vane slot was an issue too.  Also, we could never get the porting to work well; either large flow losses due to small port size, or (with larger ports or more of 'em) rapid vane wear due to high edge loading on the vanes.

RE: is this better engine?

I dont see how the dividing plates would ever stand the combustion events, plus as Greglocock mentioned, there are lots of sealing areas that cannot be sealed effectively.

Also, whenever I see a website that spends more time on investor relations and corporate videos instead of the bread and butter stuff it reminds me of an old snake oil salesman.  "Toss them enough fluff, someone will eventually bite", or "Dazzle them with brilliance, then blind them with bull****".

(OP)
I suspected as much,if it sounds too good to be true...!

I've emailed the regtech.com rep asking how many hours
will that engine last before needing an overhaul,
and they wouldnt give me straight answer just the usual sales pitch and more propaganda,
which proves its nothing to get exited about.

RE: is this better engine?

Looks as efficent as a turbine. Maybe much less.
