View Full Version : Need Help! Help me wrap my head around pressurization

04-23-2011, 12:33 PM
I have built a test bed that I am using for experimenting with stirling engines. The engine is 2 cylinder alpha with the hot and cold being the same size (1 inch stroke by 2.3ish diameter).

Now the engine starts running on its own at about 450 - 500F hot and 60F cold. I am wondering how much lower I could get by pressurizing the whole system. Trying to find info on this and having a hard time. the max I am thinking is 100psi. I am hoping to get under 400F.

thanks a lot
