@ MW383

Jim,

I am starting to get this drawn up in 3D cad. What I have is probably not correct but I will forward pictures anyway so you can mark up for corrections. Bit by bit I can get this fully modelled.

, MW383
Thanks MW, I am looking forward to seeing the pics of what you have done, I appreciate you doing this for me, just send the photos to my email box and I will examine them from there.

I have another drawing of the way the engine flywheel end couples into the fixed base end plate.
There is a stubby shaft protruding from the center of the flywheel, the end goes into the inside of a porous bronze bushing which is fixed inside the fixed end plate.

This is to prevent any out of round occurring or flexing of the output shaft and wobbling of the flywheel.

@ MW838,

I decided to draw up and photograph a paper model of the 4 stroke principle, which I have been able to combine the 2 revolutions into a single revolution. :D

@all,
There are a series of 13 photos, keep your eye on the ARROW denoting the rotation of the flywheel.

As I don't know how to put a photo with its text next to it, maby someone might like to try this, until then, you all will just have work it out for your selves.

I have also made 2 Tiny Weeny Videos, which will be posted after these still photos.
Look for the "paperclip" and click on that below the "pink" icon. TA.

Rotation of the flywheel containing the recessed groove is ANTICLOCKWISE
Firing mixture takes place at the first position, the flywheel does 1 revolution, and the cycles start all over again.
Enjoy.

1778 = All valves closed, mixture fires, flywheel rotates anticlockwise, the mixture has several degrees of flywheel movement to totally burn.
1779 = Beginning of position where piston on square shaft begins it's downwards FIRST power stroke.
1780 = Piston is travelling downwards, driving flywheel further around.
1781 = Piston and square shaft almost at bottom of stroke.
1782 = Piston is at bottom of stroke, beginning of SECOND stroke, which is the EXHAUST stroke, exhaust valve opens.
1783 = Piston rising upwards, driving burnt gasses out through exhaust exit.
1784 = Piston rising, almost at top of stroke.
1785 = Piston has reached top of its stroke, exhaust valve closes, INLET valve opens
1786 = Piston is descending, intake gasses enter cylinder, the THIRD stroke is underway.
1787 = Piston almost at the bottom, intake valve closing.
1788 = Piston reaches bottom of stroke, intake valve closed.
1789 = Piston travelling upwards, compressing flamable gasses, the FOURTH stroke is underway.
1790 = Piston has reached top of stroke, the mixture fires, which drives the piston back down again. to begin another series of cycles.

  ;D

@All,

Before I post these videos, there is someone who is making a 3D model of my Dudgeon Engine, this is MW383, I am looking forward to see his results, perhaps these flat paper models of mine can be of help to everyone too.
Remember a 3D model will be able to show far better detail than my hand drawn scrappy looking thing.

Tonight I decided to make a short video which is accessed by clicking on the "paper clip" just under the "pink" TWV icon that jeanna on the Joule Thief forum so kindly made for me, thanks jeanna.

I decided it was time to make a paper flat model of my Dudgeon engine.
With a new operating principle, it takes a little time for someone who has never come across it to understand its operation, it is very simple, nothing complicated at all, however most people will have difficulty trying to figure out how did I manage to get 4 strokes, which in today's engines need 2 Revelations to work, to work only on a single revolution.
To most mechanics and engineers, this is totally impossible, ha ha, not any more.

The first video has my Aussie accent, explaining how the engine works, it's not very long about 12 seconds, you may copy the video if you so wish.
The second video, I will post in its own section as we can only upload to a certain limit per post.

Enjoy my gift to the world. ;)

@All

Here is the last video, as I promised, no voice over to explain it, just silent movie.

If there is anyone cleaver here, you may double up the speed if you want and maybe make it a bit longer to look at too.

Correct me if I am wrong, but isn't your design just like the 1950's Wankel Rotary engine that Mazda uses today? It's a very cool design eitherway, but when I see rotors in place of pistons, I can't help but think zoom zoom zoom, yeah yeah yeah yeah..lol

Remember that little jingle Mazda had for it's car commercial a few years back? That song burned itself into my head I guess.

Anyway, your design just reminds me of the Wankel engine. Here is a link, see what you think and let me know please.

Thanks

Hello t3t4,

I just went to the link and took a look see at the wankel engine, as you asked me to.

Looking at the moving image and reading the blurb I see the wankel needs 3 revolutions of its central shaft where as my design can do it in 1 revolution.
There are 3 firings the wankle can do, where as my engine can do 1, however if my engine does 3 revolutions, then we have it on par with the wankle.

My engine has no gearing, which is another pluss.


If someone was to bolt on another cylinder on my engine, then we have doubled the power instantly where as the wankle is fixed to it's design, unless they make the area size larger for the whole engine.
But if they were to double the wave groove between the highs and lows, then a single piston would give 2 firings per single revolution.
If the wave groove was to be doubled again, then you would get 4 firings in a single revolution.

If someone made a very large flywheel, to incorporate even more wave grooves, then you could have 6 or 8 firings in 1 revelution of the flywheel.

Then again, if someone made a single round groove and placed it as an encentric around the center of the flywheel, then you would have the same old 4 stroke principle working as a 2 revolution engine, but with no crankshaft or camshaft, see 1824 below.

Thanks t3t4

Yeah, I understand. It comes down to sequence of events, the more events per cycle or revolution, the better. Although, I imagine a point of diminishing return may be reached quickly in terms of fuel requirements and/or fuel efficiency. Decreasing parasitic drag by decreasing the amount of moving parts is great for increasing overall efficiency. But, we still have that thermal waste to deal with in the end.

I do hope that you build your engine, I'd love to see or hear some test results.

So I'm just thinking out loud here with an image of the Wankel and the piston type air plane engine in the front of my mind. One small engine with multiple combustion events, but pancake thin. The air plane engines use a master connecting rod with a bunch of smaller connecting rods attached to it. The Wankel uses egg shaped cylinders with rotors. But to add rotors, you add length to do it. Such as the Mazda 12b and 13b engines which are twin to triple rotor engines. But the 13b won't fit in a suitcase, but the 12b will, almost. The airplane engine has many cylinders and many combustion events, but it's big and heavy and still uses too many moving parts.

So you use a grooved flywheel in an eccentric rotational pattern. I'm thinking of pump gears at the moment. What if, you used something like an automatic transmission pump which are a set of gears. If you've seen them, then you know what I'm talking about. Their smooth lobed gears that run eccentrically. What if, you had a combustion event with each mesh of each lobe? That would be much like what your engine design is, but adding to it like adding cylinders on an airplane engine, and still being pancake thin, but eccentric in rotation like both yours and the Wankel engine.

Large pump gears would be like a flywheel, but it would probably be lighter. Due to it's shape and design, it could have 50 or so combustion events while consuming very little space. So it would work just like your engine and the Wankel engine, but with the added (so-called) cylinder capacity of an airplane engine, all the while not growing an inch in thickness. It would still be a 2 stroke engine though, as I'm seeing it that is. Or it could be altered to work on a half lobe base which would probably be required just to keep the thing from shaking itself right out of your car.

Yeah, large egg spinning fast ='s broken car, unless the combustion events where offset.

But anyway, your posts got me thinking, I believe you have a really cool idea and I hope I explained above what I'm seeing in my head. At least somewhat,,,lol. I wonder how much power could be produced with an engine like yours or the one I described, which is still the same thing, just different. But either way, there will be an RPM limit! Not so much for mechanical integrity, but more for the fact that gasoline can only burn just so fast, which is true of any fuel. Even jet engines have an RPM limit, but it's up there above 100,000 revs somewhere. So this is a neat project, if you need help building it, just say when.

Thanks Jim,

t3t4

@ t3t4,

I never seen inside a automatic gearbox, strange as that may be, and thanks for the kudos, very much appreciated along with the offer for help.

MW383 has offered to make a model on 3D engine graphing tools, which will be way much better than my simple paper cut out lol.
I'm just waiting to see his jpgs of it, but he is a very busy fellow, so I am patiently waiting, theres no hurry, it's been in my head for decades, a few months or years wont matter.

I have to congratulate you on being about the first person to take a single look at it and have been able to understand what it will be able to do.

I have posted this engine here as I want as much input as possible, any improvements that anyone can think of, lets see if they are possible, then if used, that person can brag at his own Kidd's/grand Kidd's, see I had something to do with this engine.

Last weekend I saw some large flat 12" diameter x 1 inch thick steel disks, there were 5 or 6 of them.
I might go and see them in a week an make an offer, hmmmm.
