Re: Heater & Regenerator Design
Whatever you do. Just don't let the working fluid get inside the displacer, not even through a very small hole.

Re: Heater & Regenerator Design
As long as there is no passage way to the engine working fluid, it is fine.

Re: Heater & Regenerator Design
If the inside of the displacer sees engine pressure, it is dead space.this is open in the displacer can and in the crank case, so it always sees engine pressure

BTW. He is just pressurizing the cylinders, not the crank case. Defies all conventional stirling thinking.

Re: varible phasing
Yes. If you increase the temperature and change the phasing to close 0, it looks like an IC. Oh, you can get rid of the cold cylinder too. The point of a stirling engine is common material can be used and some how produce the comparable amount of power. In order to do that, the power from suction ne...

Re: What are the challenges for making an engine that does real work?
Yes. He did with his 230w engine. Magnetic coupling can also transmit high power through a thick "semi" magnetic medium; but not the way he did it.

Re: What are the challenges for making an engine that does real work?
Magnetic couplers are nice. But the designer has to make compromise between weight and torque.

Re: gamma stirling engine scale
The problem is to get your 3.5 psi across the entire stroke is every difficult. One better show a detail analyse before claiming an effective pressure. On top of that, as the engine gets bigger, heating/cooling gets more difficult.

Re: Alpha type stirling engine Problem
The bigger problem is. If your engine does not run because of seal ring friction, the engine is not produceing much power anyway.

Re: Snifting valve
Most stirling engines already get down to crank case pressure before maximum internal volume (because of small temperature difference). Without the snifter valve, the engine is just pulling negative pressure and losses power.

Re: A Timing question
Yeah. 90* offset is not optimum for alpha engines.the ALPHA motor is a Ross Yoke type, and the angle is somewhat different, 120*

Re: Alpha type stirling engine Problem
Please provide data for the following questions to start.
What is the total volume (including dead volume) of the engine?
What is the hot/cold gas temperature? I am not talking about heater and water temperature. I am talking about the temperature of the gas in hot and cold cylinder respectively.
