sorry guys. back in the 70's a group at MIT ran a 24 or 32 vane engine. it had been run to 27,000 rpm at time of article, and produced lots of power but like turbine engines turned to many rpms to be practible in cars so they didn't know what to do with it. read about it in popular mechanics or mechanics illustrated. i think it might make a cool airplane engine.

@69aussieguy

yes you are right i dont see it ether. this engine cant work, as shown here

[69aussieguy]

@plavins1 No that's not what I was asking, I know how the air is sucked in...it's just like some oil pumps. What I don't see is how the air, once compressed, gets behind the vane it was in front of....there must be a chamber off to the side or somewhere for it to get pressed into, however this would cause a problem for the seal on the end of the vane.

Personally I think this engine has never been built and can't work if built as shown, so all the claims in the video are complete crap.

@69aussieguy it gets sucked in by negative pressure created from vanes sliding away from air intake port

I have a project created in 1998 which is basically like yours, was stopped but now I'm picking up where I left off, then I tell you friend, you're on the right track, just make some adjustments in the engine or when my're ready we can exchange ideas, good luck, your engine is interesting.

i smell wankel engine here 

[xMoose338x]

@69aussieguy the vain should make negative pressure in the champer once it passes the intake port, the space between the veins would increase and the air fuel mixture would be drawn in....

[69aussieguy]

Maybe I'm just plain blind, but I can't see how the compressed air gets from one side of the sliding vane to the other where it is burnt.

BTW has this engine actually been built? If not, then how can anyone make such claims?

[spentacle]

That's VANES not veins. The layout doesn't look much different to an air blower. What I can never understand is how people have the nerve to make claims about greater efficiency, more power etc. until they have actually BUILT an engine and run it on a test bed. Most of these ideas have been tried before and dropped, albeit often because the materials of the day were not up to it.

Note - very high surface area to volume ratio (same problem as the Wankel) There will be very large energy loss to the coolant and so low thermal efficiency. Flame quench will also be an issue resulting in high un-burned fuel content in the exhaust. In fact, the black smoke shown in the animation is prophetic of this!

The seals will be more problematic than those in the Wankel because of both rubbing/fricition/wear problems and the length of them when fully exposed.
