Re: [alternativeenergy-224] Stirling engines and vacuum tubes - It is a VF500  engine. The plan is to use the engine with as little modification as possible. So, lubrication would be handled by the oiling system already in the tabor Sep 19, 2011 2:34 PM
Re: [alternativeenergy-224] Stirling engines and vacuum tubes - I'm curious now. What kind of engine was it? What about friction & lubrication? Does it have piston rings? Those may have too much friction. m On Mon, Sep 19, 2011 at 2:08 PM, tabor wrote: > It's a 90 degree block w Mitchell Sep 19, 2011 2:20 PM
Re: [alternativeenergy-224] Stirling engines and vacuum tubes - It's a 90 degree block with a shared crank pin so it's already perfectly 90 out of phase. It's actually a 4 cylinder so it will be functionally 2 engines running in parallel. I plan to remove the cam/timing chain, permanently seal the exhaust  tabor Sep 19, 2011 2:08 PM

Re: [alternativeenergy-224] Stirling engines and vacuum tubes - It's an alpha type made from a 500cc engine. There is lots of testing to be done but the plan is 300psi, air, and I'm hoping to get useful power from it. I was thinking of manufacturing a plate system using stainless foil.
