Tommey Reed's Ratchet Engine test fire, using HHO as a fuel...

[Tommey Reed]

This is the first test fire using HHO....

Hi Tommey,

Good to see you back on the road.

What you are investigating is basically the "hammer-effect" of the water
which is due because of the implosion of the gas.

You are not alone on that yourney.

Hi Tommey,

Great work and good to see you back, looks like a big kick from the little amount of HHO being used. How much torque, estimated, is that producing?

[sm0ky2]

If you seal the water-chamber, it will result in a greater expansion.
some of that energy is being dissapated in the displacement of the large water-mass. If the container is sealed, all that energy is placed on the piston. (do not overgas !!)
this will also create a proportionately stronger vacuum-force
this "vacuum" is caused from the two gases becomming a single (more dense) molecule. this leaves you with a very low pressure between the water and the piston-head.

if you shrink the piston further, maybe the size of the shaft thats currently on top of it.
build a smaller ratchet-engine for it to operate, and you should be able to significantly increase the timing, with the same ammount of gas you are currently producing.
with the sealed water-chamber, it should give you plenty of torque to do something useful, even with a smaller piston/less gas being used.
and the advantage of being able to rapidly fire at a constant rate.

a simple timing circuit on the ignition, would allow gas to build up for the 1 to 3 seconds or so required, and fire again.
this could be achieved with a flame-arrestor and a constant gas flow
