Response to Displacer Gland Material
<t>James,<br/> <br/> The displacer (rod) bearing is not a conventional gland, because that would cause too much friction. There is no foam involved. It is a close-fitting brass tube, fairly long to minimize the leakage. The rod must run absolutely freely in it.<br/> <br/> The regenerators can be of ...

Response to Piston sealing
<t>Because most model hot air engines have little power they are much impaired by friction and leakage, so the piston seal is a worthy consideration. There are many factors, which can be followed till . . . ZZZzzzzz.<br/> <br/> Three kinds of seal are regularly used, although their engineering is no...

Response to Reusing loss heat
<t>Hello John,<br/> <br/> You ask >how much heat will eventually migrate throughdespite the insulator reroute the heat back to the original power<br/> source?< Heat will flow only from hot to cold! However, some waste heat can be recovered by using it to pre-heat the burner air before recuperating f...

Response to model does not run
<t>Hi Jason,<br/> <br/> Any success, yet?<br/> <br/> Because the power of small hot air engines is so tiny (most of them just go, without ever driving anything), I have had to a) minimize friction and leakage, b) use a high temperature and good cooling, c) use a heavy-enough flywheel and get the bal...
