Rotary Spark Ignited Internal Combustion Engine

[airware7]

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.

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.

[MrJirksy]

i smell wankel engine here 

[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?

[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....

[plavins1]

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

[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.

[plavins1]

@69aussieguy

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

[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.

[LifesVoyager]

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.

[kissmyhyphen]

Heidrich motor done wrong.

[NearAbbeyRoad]

The bottom air intake section can also be a compressing/ignition section by pre-mixing the fuel air - as per Orbital.

The casing and rotor can be revered in shape. the rotor being oval. Then the springs can be easily changed from the casing. The spring will weaken, so easy changing is essential.

[fatqwert200]

im sorry this wont work because the pressure would cause the veins to open its a good idea on a air compressor under 20 psi...ie it takes more than 100 psi to compress petrol and more than 2000 psi for the combustion. mayby instead of springs use rotational cam to open and close the veins or pattle. that may be better but over all its not cost effective.

[NearAbbeyRoad]

@fatqwert200

"m sorry this wont work because the pressure would cause the veins to open"

The veins can be on a cam lobe.

[fferrerdalmau]

Also:

3 chambers to remove the springs.

Excentric

quasiturbine

flpas on the stator making cuts on the rotor.

.... I don't know how is the status and the progress on these types of engines... but I will enjoy if I can join to your project.

Best regards

[fferrerdalmau]

Dear Sir.

It's nice to see that I had the same idea last 1994... hahaha

Really, it's incredible it's 99% the same.. . but since I had not time to develop it, I'm happy to see that someone demonstrate it works.

One day I will show you the evolutions that I've made... one recomendation...think in 3D... and you will see .

[chuckbear1961]

I see the heat jamming up the vanes ,and springs weaking from heat and over work.

your engine would work in a low pressure application BMEP less than 100 PSI.

Clean???????? no way you have to mix oil with gas to lubercate the vanes burnt oil emissions.

[btester1]

Vengeance power is much better and it works.

[lt379]

those little spring loaded arms would snap off almost instantly

[1crazyfocker]

back up claims, thats not how it works, you dont design something then make claims about unless you have proof, like i dont know build one.... then test it. have you done that? where did you get your data from?

[dcamman]

Where is the built unit and where is your data to validate your claims??

[fdlbeats]

the temperature, pressure and velocity make the stress massive on the spring components, creating a small clearance will mean a less compliant spring and will increase the normal force, increasing frictional force, reducing efficiency. The vanes and their housings will have to be very high precision and will need somesort of bearing or really expensive polymer. It could be good, but will need alot of work. The first combustion engine was rubbish in comparison to what we have now.

[francisporters]

the 4 springs means lower rpm than a 4 stroke, so you have to invent something different sorry.

[LejeuneDirichlet]

This shit won't work.

[mafzalmr]

when ignition blasts, mixed full intaking from the other end, its imposible in same time. i have an idea more bater then its.

[cuyesama]

cool

but the fuel injection should be closer to where the air intake is id say

so that the can have more time to mix, and have an even better and cleaner burn

jus sayin'

cheers

[Otaku35]

brilliant concept!

[Florin888]

Cycle Carnot from start is limiting the efficiency of any thermal engine. Of course some engines are better than others, but you cannot claim you have a better efficiency and that is better for environment before you start a prototype and measure the percent of various burnt exhaust gases.

[Zxceelxuz]

How can you claim maximum efficiency and performance without a working prototype?

[ollieoniel]

also the wankel engine has seals like those vanes so its very possible to make this engine the only thing i would worry about is the coriolis effect on the vanes.

[ollieoniel]

diesel engines can reach 60% efficiency i think you mean higher power to weight ratio. i guess that can be efficient when it comes to transport but the engine itself would have to have a higher compression than a diesel to be more efficent.

[zaperatus]

by "burns more fuel" I asume you mean that it burns a higher % of how much fuel put into it, over a conventional engine.

[sabriath]

Why not just make a jet engine then? I mean, if you are continually going to feed gas and ignition to the process, might as well have the least amount of moving parts right? You have 4 high-tension springs moving against a barrier...a jet engine just has 1 rod through the entire unit with fans connected at specific points.

[robinhooodvsyou]

What the fuck are they talking about efficiency if they haven`t tested it.

[DragonFlyback256]

This is no different in principles than the Quasiturbine, only a simpler approach. I don't see a way it can work cleaner or with more efficiency than a Wankel engine. Vane is just another word for apex seal. (And so with its sealing / jamming problem.)

[Blondets1]

my only concern i have for the vanes is jamming into the ports. I see that with the springs there is no way to hold them back unless the ports are smaller and there is a grove to keep from jamming.

[primeobserver]

The sliding vane principle has been tried as an IC engine many times. So far, no one has published details of geting one to rotate quickly enough to produce usable power without self destruction.

It has been somewhat effective as a pump for many kinds of liquids and has been proven to serve as a moderately effective hydraulic motor, all at moderate RPM.

The principle, numbers among the earlier applications at the US patent office, much prior art available.

Best of luck and a great animation.

[InventorWillimczik]

This principle is about 100 years old and is used as hydraulic oil pump for the steering system, developed by Mercedes Benz. Nobody succeeded with this principle as an engine. Even if, it needs oil in the gasoline for lubrication, what is unacceptable today. Sorry, but a nice animation.
