From time to time the newest piece of snakeoil comes down the pipe. Since they are without merit, they obviously never come to fruition. But I read this and I am very intrigued. As a former tranny builder I understand the strengths and benefits of planetary geartrain parts. I was shown this link by someone in chat. I hope I am not duplicating a post already here in the boards.

the ramifications in my mind are that if this is further expanded upon that it could result in the gearing for the engine to be in the engine as well (not stated on the page). I figure if I can visualize it Im sure those much smarter than I could as well.
The current trends of smaller piston bores and large strokes to control emissions are right in line with this technology. I also see its integration with the newer displacement control systems like "displacement on demand" the lack of a rociprocating assemply that is revolving as well as oscillating could help control the inherent vibrations of the "shut down" cylinders. I understand there will still be oscillation but on a smaller tighter scale.
I know that NASCAR has guys whos job it is to investigate emerging technologies that allow them to "cheat" within the rules. If this has merit we will see rules there as well. At the very least it might make a way to make some LEV's that still have engines. I posted this here due to the more scientific responses I have recieved only in posts here in power adder. It likely could go elsewhere but I would not get reasonable feedback. There really isnt a theoretical area unless you count the street ricing area.

Tell me what you think?

Very interesting!

I found a good site showing what happens in the planetary gears.

Set the moving gear to half the size of the fixed grear and watch.
When offset is 0 you get a perfect line.

That is an interesting concept, seems to work very well in the spirograph sim site. I like new ideas like this...even though he just addapted a childs toy to engines, I think its cool.

It should even be possible to make the piston and rod as a single unit. Then the skirts could also be removed from the piston making it lighter because the rod would locate it square in the cylinder bore. With the piston skirts removed the 'rod' can be shorter without the piston to crank clearance problems. The cylinder head will be closer to the crank center for an engine with the same stroke making it more compact.

The 'flying' cylinder heads are the size of the conventional engine.

wow joby very interesting fact I never thought of about those skirts. Reduced friction AND reciprocating weight. Just imagine what ring seal would be like. maybe only one ring would be required too?

Tom check this out! Another interesting thread.

That motor would share the same "invisible" line pattern/stroke as joby's diagram

It is as I had fered there actually was already a post on this listed on the site. I have used the same link he did.

one time down the track, a couple 7000RPM shifts, and a 250 shot aught to turn those little teeth to dust.

B4Ctom1

those little "teeth" dont seem to be turning to "dust" in any of the Wankels Ive seen...

Kingtal0n

true but this thing isnt a wankel now is it? it actually has a piston and rod... which completelly throws the game to chaos.

detonation is killer...

JoBy

That has nothing to do with anything ... Put a 250 shot on your lawnmower and watch it explode with a conventional crank ...

This engine could be designed with strong enough gears, no problem. It is only a matter of using strong enough parts for the power you are producing.

B4Ctom1

I must agree with Joby on this. Of all the crappy ideas I have seen here on "teh intarweb" I think this may be the first bottle of "snake oil" I have ever seen that can really "cure cancer"

We know that if a gear is weak it can be made stronger and bigger. solution is as simple as the question on this one...

Well, it does avoid many of the sealing issues of a wankel and to a lesser extent of a piston engine.

The big debate is if it could be built in a way that you'll end up with fewer losses to the extra moving parts then you have with the more traditional assembly that we're already using. I would also imagine that it would be a pain to get balanced with larger displacements.

B4Ctom1

yes but think of the cylinders could be clustered together tightly in a narrow V formation or even a W arrangement like flowers in an floral arrangement.

You guys are no fun! I just wana see it explode thats all... sheesh

B4Ctom1

yeah like THIS!

EXACTLY like that!!!!!!
