Found this link to a new engine that looks very similar to the rotary. Inventor says it will be very economical.

Sure it will, we have all heard that before

Hope this isn't a repost.

Will it flood?

Ugh, it has 4 moving parts as opposed to 3. Clearly inferior to the mighty Wankel

Looks like it could have significant TORQUE(!) considering it is producing power in a similar way to a rotary, but at a much further distance from the centerpoint of the engine. Probably also a much lower speed engine compared to the rotary as well.

Let's see, they claim 500 ft/lbs torque, 350 HP and 100 mpg.

But when they bring it to the U.S., they'll have to retune it to preserve the catalytic converter life, so it will only be 100 ft/lbs, 150 HP and 19 mpg.

Sorry, but I think those boys from Kentucky should stick to building stills not engines.

Google quasi turbine.

The concept of operation at detonation is very good IMO.

Great, just what the world needs - ANOTHER rotary engine!

So many new age rotary engines....so little progress to actually stick these things into something worthwhile.

Until these people buy some car and stick one of these things in there to prove to the world what it can do, it's all just a dream...far from reality.

I'm glad they are looking into better engines but I've heard about so many "new" types of rotary engines which never come out of development that I no longer have the gleam in my eye when I hear about it.

"The comment was “It would be easier to spin the housing than the wheel!” This immediately gave me the answer to the problems, all our problems. NO WE ARE NOT SPINNING THE HOUSING! For a week we tried to prove that this change wouldn’t work. We could not find a reason why it wouldn’t work."

A very interesting idea in spinning the housing.....a paradigm shift possibly. Not sure how this would reduce the number of seals needed.

Why recycle the exhaust, unless it doesn't all get burned? I would think that would be detrimental to the power production, since there's less room in the chamber for new fuel / O2

I'm having trouble conceptualizing how it works.

I don't even think that they know for sure yet.

Actually the very first Wankel rotary engine was an actual rotary engine (and not an orbital engine) and it was spinning its housing:
http://www.der-wankelmotor.de/Motore...toren_nsu.html

Wankel created a table where he classified different types of rotary engines (hundreds were invented during the last 200 years), the quasi turbine (or at least a concept that looked very similar) was also part of this table.
The reason why Wankel came up with his engine has mainly to do with his ability to patiently analyse and test all the different types of possible rotary engine concepts over decades. It's very unlikely that some Garage inventor finds a totally new rotary engine concept that hasn't already been considered before.


Also, a lot of comments on this website are bogus:
This is basically breaking thermodynamic laws. Besides it is very unlikely that any engine concept is going to be more efficient than a diesel engine that can draw back on over 100 years of development.

Check out towards the end of the video on the site. Skip all the "Imagine this and that" baloney and there is a short piece showing the x-ray of the engine firing though its cycles. Just go back over that a few times and study what's going on.

Looks like there are three moveable firing chambers that have two locating track & pins that move them out towards the rim for compression and back in towards the center for power stroke and back out again for exhaust. Pretty neat like one of the sides of a rotor moving around. Could concieveably work but the efficiency thing I'm not sure I see esp. w/such a large cold rim and so much mass to move around.

I'm glad they are trying something nevertheless... that's the only way to test out ideas... and beside being rewarding, it's likely lots of fun!

yeah, I remember 20 yrs ago when the Orbital was going to be the new hot engine good luck skinning that cat ...
