Oscillating Steam Engine

[darketodll]

where can i get a piston like that one ?

i need for my proyect

please

Hi, how slow can you get this to run? thanks, am researching for a musical experiment :)

[cffellows]

Don't know for sure, probably 80 - 100 rpm.

[AudunBarsk]

How do you meassure/find it out ?

[cffellows]

Just watch the mechanism and count off seconds. If it's turning more than once per second but less than twice per second, it's somewhere between 60 and 120 RPM

@cffellows You could use a gear reduction and draw a white dot on the slower gear and check how many times a minute it does comes round then multiply it by the reduction.

@AudunBarsk at that slow speed you can count it with your eyes

does the double action mean that there is a powerstroke every stroke? so that when it goes down it will have a power stroke and when it goes up?

[cffellows]

This engine is not double acting. The power stroke causes the piston to go up and inertia from the flywheel pushes the piston back down for the exhaust stroke.

[k0ent]

ok, the discription of the vid said that it was double acting, anyway you got some great videos, i subsribed

[cffellows]

You're right, my mistake. Thanks for pointing it out.

[chesterfield44]

Very very nice, I like that a lot :)

[cffellows]

Thanks, it's a sweet runner...

good vid i made an oscillating air engine out of legos it actually works i need to post a video of it though

[Drinutdi]

how the hell does it let air out for another cycle?

[cffellows]

When viewed from the back:

- There are 2 holes, side by side, in the column behind the cylinder. The hole on the right lines up with the air inlet, and the hole on the left connects to the brass pipe on the left. On the power stroke, the cylinder lines up with the air inlet hole. At the bottom of the power stroke, the cylinder moves to the left and lines up with the exhaust hole on the left.

10k u i will post a video response on my engine

[solboard]

So, it runs like a gasoline 2-cycle engine?

[Drinutdi]

is the flywheel to keep it going ? cause i'm bulding my own

[cffellows]

Yes, the flywheel momentum causes the engine to keep rotating between power pulses. This is a double acting engine meaning that air pressure pushes the piston down during half the cycle and up on the other half. The flywheel is bigger than it needs to be, but that's mostly for looks.

Dude you could make that like a desktop fan! xD

[justin15ac]

ya u gotta spin it the rite way!lol good vid
