All ideas are welcome, who knows we'll get there someday
Thank you

Welcome to econology!
It is much easier to make a steam engine from scratch than to modify a gasoline engine.
The much slower rotation speeds require a huge flywheel and a longer piston stroke.
Do you have a project?

We must see everything again; the piston stroke the valves, the crankshaft and in addition it must withstand the water!
It is very simple to make a steam engine and very inexpensive.
What use do you want to make?

good evening Alain
to manufacture is good, but it requires material and know-how! Do you know if we can find steam engines of the order of 1 or 2 kW, with a return and a correct cost?

Sorry Pierre-Yves
It is easy for me who is very well equipped to do it and I often forget that few people can do it for lack of machining equipment.
The easy word is more about comparing an existing engine and making one out of every piece.
I make food feeders so making a cylinder and a piston is easy enough for me, but for ordinary people ......
No I do not know where to find these engines and it involves a kettle and safety.
By searching the net you can surely find!

a steam engine is quite simple, but the explosion engine is not suitable
the steam engines have a double effect: the steam that passes through the piston ring is not lost, it is still in the steam circuit
with an explosion engine transformed into a steam engine, all piston leaks would make water in the sump: big mayonaise!
low speed for large steam engine, but small steam engine could turn very quickly too
a good steam engine must be at least double expansion: first relaxation in a first cylinder double effect, 2eme relaxation in a larger cylinder
and for a strong pressure 3 successive cylinder are not bad
the high pressure cylinder must remain very hot and thermally insulate: nothing to do with the engine block of a cylinder 4
so I see 3 double acting cylinder in tandem on the same rod
the low pressure is near the connecting rod the medium pressure a little higher and the high pressure at the top
the problem of the 3 cylinder in tandem on the same rod is the impossibility of balancing the mass
2 connecting rod vee is not bad: low pressure on one side, high and medium pressure on the other side
I like the high pressure cylinder very hot in tandem above the medium pressure cylinder

I look at the possibilities of making a chain of co-generation biomass then steam for a few weeks.
Regarding the steam, I can not find companies that work in the small steam. The only company I found is in Germany, http://www.spillingwerk.de/english/produkte.php but they do not want to do anything below 1MW, because according to them, the price does not decrease with size due to lack of mass market.
I had found a company in the USA: http://www.dynamicenergy.us/Steam-Turbine.html but the manager has retired. He still wants to work on it, he can help us.
The only country I know that still has production steam vehicles is China. But I can not find any contact for the moment.
In Europe, the only steam specialists are fans of models, with sizes that would be suitable for domestic cogeneration: small locomotive, boat.
I found the following links:
- http://www.cav-escarbille.com/
- http://www.association-abv.com/
- http://www.le-petit-train.be/accueil.html
I have not yet price contact with these associations, but I discussed with a small Belgian company, named Precirail, which seems to me expert, in particular for the boilers. It does not have a website to my knowledge, they are artisans.
I also saw a small 2x2 V-cylinder engine running, each cylinder pair being 2 (compound), 45mm then 65mm. The engine dates from 2009, made of stainless steel, given for 15 at 18KWh to 12 bars. It was done by a retiree in Germany: it would be perfect in my opinion to move forward.
Otherwise, hardware side, I identified alternators very impressive simplicity and efficiency, which would already regulate the electrical part:
http://www.alxion.com/bin/alternateur_kit_stk.html
On the steam side, I think that it is absolutely necessary to aim for a closed and sealed circuit, with as little water as possible to solve the legal problems related to safety: it would look like a refrigerating machine circuit, where the fluid is water, and where decompression is used to produce movement.
I also look at oxygen enrichers to increase the temperature of combustion, while reducing possible pollution by nitrogen and dioxin.
Here is the inventory on my side :-)
Let's move together!

forget the oxygen: it's too expensive for a steam boiler: it's just good for very high temperature furnaces where it is important to reduce the useless nitrogen flow: but the oxycombustion is not even the best solution: the heat recuperators of martin siemens furnaces are as efficient as the oxycombustion
for steam the safety regulations are completely unsuited to small dimensions: yet the refrigerating machines are the proof that one can make small pressurized machine without any danger
so any good little steam engine will be unsellable according to the current regulations: it is necessary to invent the fluid Rxxx and not to say that it is water
a lot like heat pump dealers selling machines at R290 without saying that R290 = propane
edit: no need to invent it! it already exists: R718 = water
