Very interesting web site some of these engine I never knew existed I my self rebuild
motors like 4 V6 and V8 .but never thought
of making one. for one reason equipment and machinery needed to do this is very expensive . I wish you luck in your venture.

well i am almost finished with the co2 engine, i built it out of pvc and a wooden frame. the piston is a round dowel with 2 o- rings on it. hopefully i can find a massive flywheel to push the piston back up. wonder if i put a radiator in line with the co2 line, will it provide more power with less co2 consumption...

Not a radiator, but an expansion chamber. This allows the CO2 to expand fully from its liquid state. Maybe put a warming element around it to help even more.

Interesting site. On the subject of making your own engine, I once watched a video of a machinest who made a 2 foot long scale model of a Ferarri F1 car. What was amazing was that it was fully functional, all the way down to a tiny 3 or 4 inch long 16 cylinder engine. Absolutely amazing! If mice could drive, one would have no problem driving this thing around. Sounded just like the real thing, too...

most awsome! do you think that pvc would crack under the temps and pressures from a c02 carteidge?
would this engine work?:http://www.geocities.com/cajunjoe_here
click on sengine.bmp
i would use the radiator to heat the co2

Heat it to a warm temp, or heat it in order to expand it? If it is to expand it, you need an expansion chamber so it has room to warm and expand. A radiator wouldn't give it the room it needs unless the tubes running through it were like an inch in diameter.

Every year I go to a shw of homebuilt engines, It is very interesting! There are many models of "normal" engines, and many that weren't modeled after anything at all. Im afraid I don't know of any websites, google gives me only jet engines and aircraft engines. (at least on the first page)

Seems like it would work fine, if you get the valving sorted out for the cylinders.

that is the beauty of this engine, i deigned it so i wouldn't need complicated fabricated valves.it uses sprig loaded ball valves at the bottom. when one piston goes down, it pushes the valve open, then it fills with steam, pushes the piston up the chamber to a hole in the side where the steam is sent to a condenser to be reused. as it goes up, it pushes the other piston down to restart the cycle. lke the c02 engine 'cept with steam
any ideas for a boiler from household items

no but I've got one I can mail you....to bad its so heavy. It is home bult, it has some leaks but they dont affect it (you only notice them when your operating above 70psi)

i'm lookin for something light so i can put it on a viechle, and it needs to be made out of existing parts. i can't fabricate much

Try to find a copper/brass toilet tank float, or a big soup can. You can solder on the soup can top if you have a torch, if not they are cheap to buy. Then just plumb in you piping.

Do NOT PLAY AROUND WITH BOILERS. If you are going to make a boiler, use very thick steel and find a welder you trust. Then get it certified. If you can, buy one prebuilt with a certificate. I don't think I need to emphasize how bad it can be if the boiler were to burst. DEFINITLY do not use a leaky boiler. Leaks mean cracks, which are a point of stress leading to failure.

ill have a safety relif at like 75 or 100. the design i made requires the flywheel to get to speed before you engage the clutch, so i don't need alot of pressure to get going
has anyone seen an engine like the one i designed? if not, it might be worth a patent just for the sake of it.
i had another idea for the valves. ill post a diagram at my site soon

well the one i built weighs somewhere around 35-40 lbs or so when full...its not that heavy, but it doesnt provide enough steam for a car...however I have lots of plans and materials for one which could...but no reason to build them.
As for the leaks, there from slag holes, and its save up to 100psi
