Closed free piston/displacer Stirling idea

Post by vminnen »

Just uploaded a sketched
idea with which I tried to confront some of the problematic
aspects I spotted as common to many (model) stirlings:
friction air leakage not self-starting
complicated mechanisms to ensure displacer movement timing
Apparently, free piston/displacer engines are the name of the
game in commercial solar / micro-CHP applications. But I have not come
across any model engines operating on FPD principles yet. Is this
idea is any good? Else I hope it might inspire someone for something
better...
