Re: Need a 50 watt power output providing stirling engine

Im afraid there is no such engine on the market :/ But in case you find it, please let me know, i need one too :)

Re: Need advice buying my first sterling engine

Maybe you could buy several of these to reach requested power? https://www.inresol.se/products/inresol-v2-6

Re: ITS GENIOUS™ - 10 kW portable CHP stirling

Cool stuff.
Would be cool if you sell also some small simple model for hobbyists/off the grid folks on a budget :)

Re: Noob question - would these parts work?

Soo... i'm now in process of fitting pistons into cylinders, unfortunately the tube i got has some pretty rough dimensional tolerances. Or to be more specific, it's crooked as a bygeorge. Therefore i might need to get some better quality tubes before going on with the construction. However i at leas...

Re: Engine running for short period

I would guess either insufficient cooling as you mentioned or thermal expansion of pistons increases friction to a critical level.
What materials have you used for pistons and cylinders?

Re: A Stirling theory question on average pressures

This video imho nicely demonstrates the effect of a snifter valve.

Re: Stirling power generator

Basic rule of thumb - less dead space means more power, therefore i suppose in upper picture the displacer isn't in top end.

Re: Stirling power generator

Well, imho in an engine complex like this, connecting it to an expansion tank (with additional dead volume) might be more feasible.

Re: Stirling power generator

For power regulation you may either put a valve on a channel between cylinders (limiting airflow causes engine to lose power, or better say - to waste power on pushing the air through), or you could add container with a lot of dead volume, again connected through valve to the rest of the system (add...

Re: Noob question - would these parts work?

Well, technically it still is a displacer (it displaces medium), and it even does the same job in alpha as in other configurations, the only difference is it is attached to a piston instead of a rod. A honed stainless cylinder with a well made cast iron piston will have similar friction to an ordina...

Re: Noob question - would these parts work?

Blaf, That motor gets its power from being an ALPHA motor, it has no fancy regenerator. With a generator in place it will easily run a radio, or charge a battery. Here it is now with it's air cooling, and I'v removed the side arm on the yoke and fitted a roller that slides up and down in a slot, I ...

Re: Noob question - would these parts work?

Oh dear, i thought my order for ventilation pipes (which i planned to use for cylinders), i made weeks ago, got ignored since i didn't get any response from manufacturer. Now i've received an email saying the order is being delivered.

It seems i'll have to try to build it anyway...
