Hi All,

It's time for me to build the first true HHO engine.

HHO is not made for any IC engine, if fact it's wasting HHO just to get a engine  running due to the piston area and implosion effect under load.

This engine I'm building deals with piston displacement of 10.5" piston and a 8" stroke.

Total displacement of 692.8 cu/in.

This is not your average engine, in fact it's a hit and miss type of a engine using some of my ratchet engine designs.

This is the piston I aluminum cast  Saturday.

Why so big?

Lets look at a simple 1 psi on this piston with a 8" stroke.
Total displacement of 692.8cu/in or 0.4cu/ft

1 psi x (pi(r^2))    = 86.6 in/lb of downward force @ 8" stroke =692.8 in/lb
10 psi x (pi(r^2))  = 866.0 in/lb of downward force @ 8" stroke =6928.0 in/lb
100 psi X (pi(r^2)) = 8660.0 in/lb of downward force @ 8" stroke =69280.0 in/lb

HHO will be allow to expand freely and still produce some real output.

So based off your experience with the HHO water cannon, you're going to build an engine that uses volume instead of pressure.  Cool.

I'm guessing the trick will be in getting the most expansion possible.  You thinking dilution and possibly phase change of water to steam maybe?

When I look at your piston, the first thing that comes to mind are those high speed air compressor pumps--much different operation than the low speed, long stroke types.

This is going to be a neat project Tom.  Really looking forward to seeing what parameters you zero in on to get the best performance.

BTW, this is very much "On Topic" if you'd like me to move this thread to the project section, I'd be happy to.

Tommy, hows it coming? its been 42 days sense you posted an update :)

looks good, its all-ways interesting to hear how things work, or don't. its a way of teaching :)
