Cycle Circle engine

Check out this unusual engine. No crankshaft, no piston rods, and much less to go wrong. See it at [www.circlecycleice.com]

Hmmmmmmmm....... Well, it's good to know the internet isn't letting us down, yet another engine that doesn't waste power due to the piston reciprocating (but doesn't really answer the question as to why very short stroke crankshafts don't seem wildly more efficient than square or long stroke). Their geometry seems suspect, they claim ..."Unlike the Otto Cycle engine whose maximum lever arm (torque) is achieved when the piston is halfway through its power stroke, the CC engine lever arm is increased through the full travel of the power stroke..." I dunno, their pistons and cylinders orbit around a center while remaining aligned in the same direction, which would seem to give them much the same lever arm situation. Given all the rotating parts, and associated gear trains, seems hard to pinpoint the dramatic friction reductions they claim. I will admit they seem to have a video showing the engine in operation, but it's the same Tesla turbine demo we see everywhere else, a spinning naked engine. Where is the load to prove it is making power? Better yet, where are the dyno and smog tests to prove all these claims for superior efficiency and cleanliness? Lest I sound a bit cynical, I keep remembering that inventors like Bell, Edison and the Wrights made real demonstrations before asking for money rather than asking for money in order to make demonstrations....

Whoo Boy, here we go again. Double talk and smoke and mirrors.

Seems funny that these fantasy engines are always CAD drawings and never real working hardware.
Absolute nonsense and only goes to prove the incompetence of the Patent Office these days.
Ken has it right. Where is the dyno and where are the real numbers? For that matter, where is a real engine and not this cartoon version?
ABSOLUTE B....S.....

If anyone is interested, I still have that bridge in Brooklyn and that block of Tesla Turbine stock to get rid of. Even the cat gets mad when i use it to line his potty box.

It's really amazing how brazen some of these guys can be. I remember one exhibit at an early 90s SAE conference for the "split-phase" engine from Australia. It would supposedly run at a compression ratio of less than 2 to 1. Very complex action, hard to figure what was happening. They even had an honest to God WW2 hero, knighted by King George VI, as their CEO. I guess they figured no one would consider someone would have the gall to push a fraud in a collection of engineers that big.

They did. Total scam, but took years to unravel. Sad thing was, they actually had some good technology in the beast, but they were more interested in bilking the investors than making their good stuff commercial.

We have had this argument so many times. There really is not enough friction loss in the crank mechanism that any crank mechanism would have any significant efficiency advantage over the normal crank. it could be worse. But the simple conecting rod is fairly low friction loss. That's not to say that one might have advantages over another for other reasions. My excentric 90 degree V wasn't acceptable to many. But I was not claiming an efficiency advantage, I was trying to achieve a more compact double acting engine. That was 20 years ago.

I think you will find that was the infamous Splitcycle engine promoted by Ricky Maine. Their stroke of luck was to have Sir Jack Brabbam of racing car and drving fame tell everyone how good it was (hero but not from WW2). People believed Sir Jack and Splitcycle took in 10 of millions most of which disapeared into luxury homes and cars.
The engine used multiple 2 cycle units running on geneva wheels. I wrote a report and explained it was basically 48 10cc model airplane engines geared 12 to 1 to and out put shaft.
I don't think there was one piece of vaguely good tech in the aglomeration, it appeared just designed to part greedy technical illiterates from their money.

How's this for a motto?

THE INTERNET.....BILKING THE GULLIBLE SINCE 1988!
