Rotary engine running

[JaxxBat]

More insanity...

[Krumme1979]

@JaxxBat LOL!!

Prude :-:

[AutodeskInventorDUDE]

Nice concept! Check out my rotary engine design; it's called "New Engine Idea" if you can find it right in my channel.

it's an early design, btw. It doesn't work at all (as I predict). I have a much better design coming soon or later.

[meetyourdoomBRA]

Hey, i dont get how it works. it looks like a great engine. Hey im a fan of engine of all kinds, i live it. i wanted to know if is it a combustion engine, if yes, can you make an animation explaining where the fuel enters then engine, when it burns, and when then smoke leave. something like this /watch?v=_y6PS-2j2Ug

[Krumme1979]

@meetyourdoomBRA

Have a look at the 4 descriptions in the beginning of the comments. They pretty much explain how it works

[JaxxBat]

@meetyourdoomBRA , It wont work well , rotary valving issues not with standing..Until a working model is under extensive testing it is all theory..

[crudeoilsystems]

nice program and work

[Workmule4ever2day]

Wow! Your looking at a serious timing "crash"if you not tdc every rotation. Idub this engine Clock Work Orange. Cheers to your forward thinking. You would enjoy reading about Planatary Trespin Gearing. An exterior gear that would give you real time sync ability. Cheers again!

[KBTuning]

i dont see where the power stroke would be, all i see is where it would bleed off the pressure you just made...

[Krumme1979]

@KBTuning The pressure is stored in a small rotary "cup". It is stored just long enoug for the piston to pass through the rotary valve. It releases the pressureised gas on the other side of the valve between the valve and the same piston that build the pressure. Have a look at the other video i have (Rotory engine assembly). You'll see the "cup" or "delay valve"

[nemanume]

Please tell me the name of the designe program ...

[Krumme1979]

@nemanume

This one was made in Autodesk Inventor 4.0

(so quite an old program)

[TMNT34]

@Krumme1979

dude you should get some of the that solid works! prettey easy

[trevortravels1]

nice one mate

[zncus]

Can you please tell me what software you used to make this simulation?

Thaks

[Krumme1979]

@zncus It is just made in Inventor 4.0. I used the "animate" function where i plot in displacements. It probably isn't the right tool for the job, but in this case it got the job done.

The "animate" function can not be used to animate a piston going up and down, but it can be used as long as the parts do not switch direction.

(at least it couldn't in 4.0)

[SEThatered]

Pacman engine...

...indeed something new!

[fallouter32]

its impossible to compression is not large enough

[fallouter32]

its impossible to compression is not large enough

[solitajre222]

I just figured it out! That is most likely the smartest solution I've ever seen...

You should copyright it before someone steals it! =3

[hansschreier2]

expectacular.. I love this.. Fantastic....

[sof1map]

looks like shit

[sabriath]

You have 4 compression strokes at the SAME time, and yet....where's the power stroke? It's like they compress, then the disks open up and immediately fills the cavity ahead. Sorry, but I just don't see it. Nice concept though.

[Krumme1979]

nono the compressed gas is transfered into a new chamber that holds the gas until the piston has passed the valve. Then it releases the gas on the opposite side of the piston and ignites. My other video where i make an assembly of the engine might show you what i mean

[redghost105]

@Krumme1979 alot of moving parts...it would use to much oil and cause to much heat

[ridethroughlife]

this engine is awesome, i love the dynamics..but youve always got to think 'can i make this smaller and available on a motorcycle...when youve got that, youre on to something...PM me for details, son.

[Krumme1979]

Thanks!!

Yeah its true what you say about the small engine.

The dynamics are somewhat taken directly from Wankel. All rotary parts.

Unfortunately the idea was patented a few years before i came up with it.

Some canadians i thing. It's called "Round Engine" (you may find it on google)

[dedwards8708]

cool but complicated, check out the edwards Winged Rotary

[Krumme1979]

We seem to somewhat think alike. We both focus on the "all rotating" engine. I posted a concept engine a few days ago where i focus on keeping an equal amount of torque on the crankshaft.

I see where you're going with your engine. It is way more elegant than mine. Fewer parts!

I'm just not sure that the expanding gas in your power stroke will apply all force in the moving direction of the engine. I do understand what your saying about the rifle but some force must be applied backwards??

[hippo459]

how exactly would this work? i can see the compression stroke but then how does the power stroke work?

[Krumme1979]

Well when the gas is compressed it is forced into a delay mechanism through a tube. This is best viewed in my other video where the assembly of the engine is made. The delay mechanism holds the compressed gas in a rotary "cup" where two holes must allign in order for the mixture to escape the chamber. The piston passes through the rotart valve and when the valve closes again the holes in the delayer allign and the gas is now BEHIND the very same piston that compressed. Then the sparkplug fires

[ADHD20B]

only Felix Wankel could ever come up with another internal combustion engine in a radically different way. and that same engine is being used today.

its wierd that theres only realy 2 types of internal combustion engines in the world that actualy works. on cars, boats, bikes etc.

i love how people are experimenting and comming up with different engie designs. keep up the good work ;)

[324Ben]

It is still a great idea,despite that someone else had the idea before you;the good thing about that is that you can learn from their mistakes.

[324Ben]

Well,Trice in UK and Round Engine in Canada both patented this concept,but neither of the companies are the first to patent this concept;the concept dates back to 1930s or even earlier.I have seen several earlier patents on USPD.

[Krumme1979]

really? Hm

I thought i had i great idea here, but i turns out someone had the same great idea about 80 years ago... darn

[FoZZy1300]

I know the feeling, every time I draw up a new engine, I come on here and find foru videos with the same engine I just drew : /

[FoZZy1300]

I do really like this engine btw.

[Krumme1979]

thanks!! yeah i suppose you're not gonna make the big bucks inventing engines these days.

I did contact the canadian website as mentioned above (round engine)

Aparently a prototype has been made and HAS run. I asked for a video of some sort, but unfortunately they could not send it to me (it was to rough and homemade and i think some content was classified)

[astixxx]

if u dont mind...where did u saw this patented? is there a site where i can see it too?

[324Ben]

Google 'Round Engine' ;it should take you to the Canadian website of a similar concept.

[pzpepsi]

i thought something like this when i was walking home from the 6th grade a long time ago. the conclusion is it would wear out within 20k miles and it wouldnt just wear out but completely destroy itself once a main component busted

[Krumme1979]

I have another video that shows the assembly and components.

I don't think it is impossible to bild, but i do see the challenge...

[fangus503]

this looks impossible to build

[Krumme1979]

Yeah... I had the same feeling when i discovered that the idea was patented.

The patent belongs to a mr. "John Archer"

You might be able to find some info on the engine called TRICE.

"True Rotating Internal Combustion Engine"

I suppose we both had the idea, but the patent isn't mine :-(

[PavelNr1]

It´s my idea!!!

[Krumme1979]

DESCRIPTION 4

The piston passes valve at 1 o clock and the valve closes again. The next pistion pushes out the remaining exhaust through the pipe.

Damn hard to explain, but thats more or less it.

The same steps repeats in the other half of the engine ( counter clockwise from 1 to 7)

[Krumme1979]

DESCRIPTION 3

The pistion passes valve at 4 o clock.

Just aftter the "delayer" opens.

Compressed fuel mixture is now in front of the piston. Not behind it.

Just as the "delayer" opens, the spark flies and you have the power stroke.

the combustion chamber is sealed by the rotating valve at 4 o clock.

Now the piston is being moved forward until the valve at 1 o clock opens. Just before that, the pistion passes the exhaust pipe (seen as the thick pipe on the valve at 1 o clock)

[Krumme1979]

DESCRIPTION 2

The fuel mixture is transported a bit forward (by two pistons) untill the valve at 4 o clock closes.

The mixture is compressed.

The compressed gas is pumped up into a chamber above the piston. The purpose of this is to delay the flow. (it is better seen in my other video)

The piston it selv seals the "delayer" where the high compressed fuel mixture is now kept.

[Krumme1979]

DESCRIPTION 1

It's damn hard to explain in text but i'll give it at try:

The engine has 2 combustion chambers (two plugs)

What happens at the first half of the "dognut" repeats in the second.

The first step is vacuum. The first piston pulls in gas (approx. at 7 o clock).

This happens because the rotary valve behind it is sealed and fuel is therefore sucked in through the thin intake right next to the valve.

(Continued)

[majom89]

It works other way like the Wankel rotary engine in the Mazdas but yes, its a rotary.

And how it works? I just cant figure it out from this vid

[Krumme1979]

Magnets? Nono it's just a combustion engine with spark pluggs. The valves are rotating aswell as the pistons. The idea was to design an engine consisting of only rotating parts.

This uses magnets?
