Thank you Longboy, I thought this might be true as it seems logical. I am slowly working towards designing my engine design. I have never done this before, so it is a sharp learning curve. Initially I was trying to find a prototype model maker, but it's quite hard to find someone who can work with m...

I only came to this site, as an answer to a question while 'inventing' a different type of engine. It uses tried and tested technology, but with a modern twist. I remembered from my past a compressor for Hydrogen liquification, with a piston inside another. I had never quite understood the reason fo...

Thanks Ferraccio,

I'm afraid I can't show you want I'm thinking about yet, as it is in the first stages of thought. I am working on a novel type of Diesel/bio fuel engine. One of the posibilities is the double piston arangment, but it seems that I can't find whether it will take the high pressures, so I will most lik...

Thanks for that explanation Ferraccio, We are certainly at cross purposes. I am designing a completely different type of engine and only wish to know, if the piston inside a second piston arrangement (As in some Stirling engines) can withstand high pressures, as in a Diesel engine? So the rest of th...

Thanks Ian,

I'll get experimenting.

Yes, there are two pistons, in one cylinder, and both are subjected to high pressure, perhaps 20:1 and perhaps more.

I need top know if there are examples of this arrangement being capable of sealing.

So, it's called a Beta motor, thanks.

Thank you Ian, I hope that we are not at cross purposes, regarding High compression of this type of piston combination. I am designing a different type of engine, and remembered the double piston in one cylinder arrangement. I realise that different styles of Stirling engine sometimes have this arra...

Hi all, I'm new to this forum, so hello. I would like to know if anybody, has experience in the type of piston with a con-rod sliding though it, where a second piston can be mounted as in some Stirling engines, giving two stage compression. I need to know if this type of piston is capable of very hi...
