That's very useful. Thanks. Well, I don't consider condensing before the intake valve shuts to be a real problem. It won't fill up the entire cylinder in the brief moment of the valve being open.. Maybe it will make the engine "burp" a little earlier. I might just do that, if the engine does...

I think our posts crossed.. That doesn't matter, since the engine can suck in steam freely. If some of it condenses before the piston reaches BDC, so be it. i already thought about that. A checkvalve in the head, like all flame gulpers already have, should be sufficiënt to drive out excess...

You might have a point there. On the other hand: Steam collapses to about 1:1600th of its volume when condensing.. Does air do that, without changing from gas to fluid? In other words: You might throw a lot of energy into the cylinder of a flame eater, but how much kinetic energy do you get in...

Disappointment always is a possibility when you try something new and/or out of the ordinary. And advice would still be welcome, just like the experiences you had. But if there's empirical evidence that the problems you pointed out are possible to overcome, I might still give it a try. ;)...

A flame eater doesn't have a lot of power, but it still runs. If my contraption wil run, I'll be satisfied. If it could drive something, that would be a bonus. What are you talking about? http://www.youtube.com/watch?v=Uy-SN5j1ogk Someone else's did, and pretty powerful, I must say...

Hmm, they were even close to doïng what I'm planning to do.. Oh well. Still nice to give it another "modernized" try..

Fair enough. :) I didn't come that far until now.. My bad. Maybe.. I guess in a way, I'm doing that, be it more simplified. About the water injection: You can scale down an engine, but you can't scale down physics. In a small engine, the cylinder is probably narrow enough to provide...

Nooooo!! Not again Newcomen! Newcomens engine had no crankshaft and flywheel! On top of that, it had an entirely, manually operated cycle. Not an autonomous one!

If you had read my post properly, you would have seen that efficiency wasn't my main goal. It was only meant to be more powerful than a flame eater, and to be easier to build than both flame eaters and conventional steam engines. Not to supersede conventional steam engines. So there's no...

Well, maybe I should elaborate a bit more, after my "intervention"/bump in the other thread: http://www.homemodelenginemachinist.com/f26/steam-vacuum-engine-anyone-built-one-19538/#post217342 What I am planning to do, is to build a "steam-to-vacuum" engine, with a working cycle that is similar...

You made it perfectly clear. Ingenious idea. Thank you.

Great looking engine! But what does "Selfcharger" mean? Does it have a hidden compressor, or something?

What drag? I mean: The vacuum is more powerfull in order to overcome any aditional drag (look at how that oil drum inploded), and on top of that, the condensing water might even improve the sealing between the piston and the cylinder a little bit. And the Newcomen-engine.. You can point out a...
