Hi

It seems that the design of Beta Engine from Rider-Ericsission company is https://en.wikipedia.org/wiki/Rider-Eri ... ne_Company is available.
It was close to 0.5hp of power.

Can someone shed some light on what was its efficiency and whether it can be pressurised to produce a more powerful engine ?

Is it a good starting point if one want to raise it to significant power levels running into few kWs of electricity

The efficiency would have been about 5% / 10%, the real value comes in the low grade fuel, and compared to a steam engine the lack of a boiler, and it's certification and boiler man.
To pressurise a motor both sides of the piston are effected, the crankcase is pressurised, so the bell crank and connecting rods would make this design impractical as a pressurised as a pressurised machine. The simplest layout is the one often seen with a two throw crankshaft, with the displacer crank leading the power crank by 90*. The next most simple is a GAMMA, requiring only one crank pin, or an ALPHA motor of the same layout.

Thank you Ian. That was great help. As you would have know by now, I am a newbie not only to Stirling but machining in general.

Any recommendations for a published design which can be pressurised and later scaled other then the Viebech, I have some access to automated machining and can probably pull off something which most amateurs cannot so that wont be a limiting factor.

Also I could not understand "The simplest layout is the one often seen with a two throw crankshaft, with the displacer crank leading the power crank by 90*". Would you be kind enough to share a link/video showing that design.

Did u mean something like this https://www.youtube.com/watch?v=mUr6rsNgBU0

hello again Ian. Im not sure I understand what you wrote above. I'm currently looking at a twin v pump design. would you say a twin v pump design is a suitable design for pressurising if I enclose everything including crank shaft and the alternator like you once suggested?.

The GAMMA, and ALPHA mentioned above have the power cylinder mounted at right angles to the displacer cylinder in a V form.

So pretty much like the video I posted
