You have plenty of heat then, but what's keeping the other end cool? Air/fins/water jacket?

Probably an obvious question but is there enough temperature differential between the hot and cold sides?

On the subject of regenerators, some builders have used a 'stack' of thin plates with holes in them. Make x number of discs and drill them all at one setting with y number of holes and a central/axial hole. Mount them on a shaft with a washer between each, turning each disc by some random amount so ...

Hi McGyver (are you the HMEM McGyver?) More to the point, we have a gap of about roughly 1/4 inch between the outer diameter of displacer piston and internal diameter of displacer cylinder Is this too much gap? If so, what could we use to absorb heat and create a tighter seal if need be ? AFAIK the ...

AFAIK these engines are generally supposed to turn at a slow RPM but I've not made either the coke can or walking beam versions so I can't say for certain if yours can be 'improved'.

Any chance of some pictures or video?

Hi there rammstein

It doesn't really have a name (!). It's a model that as far as I know it was first published in the early 1900's but refined in the 1930's. It's essentially a closed Stirling cycle like a simplified Henrici with side-mounted power piston.

Best regards

You could look at Solar Towers too

Thanks for the reply.

By luck rather than design my ratio will be about 21% so hopefully it won't be a major problem. Once she's up and running it'll be a simple matter to experiment with reducing the aperture although I won't be able to expand it easily.

Thanks again

Can anyone tell me if the size (diameter) of the port that allows air into the power cylinder in a hot air engine (e.g. model Henrici, Robinson etc) has any bearing upon performance?

Looking forward to it!

Hi, new member with an interest in hot air (as opposed to LTD Sterling) engines here. Currently building a simple engine, hope to have some pictures very soon.
