I tried to pose my question once more:
10 or 12 PSI? Could this be real? This is a pressure less than the atmospheric pressure of about 14 PSI!

I'm sorry, yes!
At 12 psi with an area of say 12in/sq or 4" piston, you will have 144in/sq..
Now the atmoshpere pressure at sea level is 14.7 psi....
So to answer your question about 12 psi, is yes.
12psi of compress air at 12in/sq piston area with a stroke of 12" will produse a total of 144 ft/lb for each 12" stroke of the ratchet engine, and a costant flow of 12 psi!

1. May be there is a great misunderstanding or I have understood you wrong. I think a piston with an air pressure of 12 psi could no do some useful work.

2. I take your formula and did some trials. I reduced the stroke from 12" to 6": The result is a power output twice as with 12 ".

If we us12psi to start with:

12psi = 12 lb of work at 1 inch of travel.

The Ratchet engine converts linear in to rotational energy, with the only lose of friction. At 99% efficiency.

If:

piston(a) 12psi at 12" of travel = 144lb of work...say 1 revolution

and:
piston(b) 12psi at 6" of travel = 72lb of work...say 1 revolution

For (b) to equal (a), (b) would need 2 revolution to equal (a)

a=144
b=72

a=(bx2)
b=(a/2)

Hi Tom
 I found this one on youTube, you might find it interesting

I did see it, but I like simple and my engine is simple and very efficient..

Yes Tom your engine is much simpler, I hope you get the chance in the future to make it

Hi Tommey,

thanks for the new video simulation from you ratchet engine.
My question: Is there a limitation how strong the push and pull from the piston could be?
What would happen if the piston has a power up to 7800 lb f?
Wouldn' that power destroy the mechanism?

I've looked at Tom's designs with an engineer friend of mine, specialized in designing things light and strong. This Ratchet Engine has great potential, and his (albeit most excellent) proof of concept will be only that. A proprietary toothed set of tracks rather than the welded in place bicycle chain, and forged aluminium or high-quality steel construction would so booth this design's max power.
Tom has offered some good calculations, but I'll just have to extrapolate those to imagine how big of an air tank it would take to make an alternative to the electric car with its modest mileage.
An HHO-only engine made this way though (maybe for now as secundary engine in a car) could be made very small, light and STRONG. Some 90% or better of the HHO being usedl versus ~20% of the petrol. And, there's just something about a combustion engine, isn't it? Electric is great for trains and busses. Taxis.
Tom's handywork being so great, it seems plausibe he could propel a full sized pickup truck with a 6-piston air engine of this scale, mostly PVC and wood. Air tank as a trailer? With such big air pockets I bet this proto in the vids will be LOUD, but power at that. Can't wait to see his gokart he'll build around it.
Seriously, it seems plausible that with the right funding (5 digit $ will do), a triple mileage petrol engine can be made. Compressing air while decellerating is just a great idea, a designated set of pistons could be there just to to re-used that energy, offering a performance boost shortly when the pedal is floored. Once you have a triple or quatruple effciency engine, that sure opens the door for HHO-on-demand-only propelled cars, which we'll all agree would be the holy grail. Trying to do that with a contemporary engine design will be multiples more diffucult to achieve.

What happened to the videos of this design in action? Ive looked everywhere!!!
