Talk:Stoddard engine

Question
Glenn, Why do you believe 'The power piston and cylinder is not shown' in the image of the 1919 Stoddard Engine? Mikiemike 12:15, 29 May 2007 (UTC)

Help! I'm confused about the Stoddard cycle!
The Thermodynamic cycle page says that the Stoddard cycle has 4 stages: adiabatic, isometric, adiabatic, isometric. But this page says the Stoddard cycle is adiabatic, *isobaric*, adiabatic, *isobaric*. Can some expert fix the page that's wrong?

Stoddard's 1933 patent --- you can see it on this page --- says: "It is to be noted that the increase in pressure at the end of the up stroke of the piston is due to the rise in temperature and not to mechanical work". That sounds like an isometric stage, not an isobaric one. John Baez (talk) 17:44, 13 February 2010 (UTC)

Because, probably, this is two different engines with two different cycles. Earlier version uses Brayton cycle, second uses Stirling cycle without regeneration. EvlSpirit (talk) 05:55, 13 February 2022 (UTC)
