    Why do they pressurize everything?

      can i see the butter?


      Please hand me the butter before I spread your eyeball on my bread?

      So...anyway, why does pressurizing the engine create a greater power output?

        My book about stirling engines has a short section on pressurization. It says that by increasing the internal pressure, the expansion/contraction ratio of the heating and cooling cycles is increased which increases the power output. The hard part is keeping it presurized a/c leaks. Hope that answers your question.

          The gas is the working fluid. The higher the pressure the higher the density of the gas and therefor the higher the heat capacity per unit volume of gas.
