First, the positive thing: Is good if you look for a book: this means that you like to be informed. Few considerations: If you want a book for built/design a Stirling engine for a car this means that you do not know how the engine functions. This book do not exist. The Strirling is not at all adapt ...

Marmick, If the design of ST is OK, copy it, and test it. If there is really no expensive there is no problem..., right? (I think is however expensive, also in India..., also in India may be costs as a luxury car ... built in India). Yelds may be are local (internal heat converted in mechanical), or...

Wellcome Marmik, I think you refer to ST05 5 kW engine. This engine seems to be beta (or gamma) type, tubes heater, atmospheric. Yeld is low (7%), is quite in good mechanical quality. The engine is expensive to built. Head tubes are expensive, and may be are substituted by other devices, although th...

I correct myself:
of the lever that BIND laterally the T lever.
Scusami, Ferraccio

Ciao Ante! I understand that you have provided the movement of the lever to "T" as vertical. This derives from the fact that you did not put in the variable the length of the lever that laterally the T lever. Congratulations for your work, if so, however, this is not acceptable, since the ...

Speaking you about beta type I suppose your interest in medium-level well-performant engine. A simple research in you tube (digit: "stirling engine") demonstrate that the question is more complex than you think. And answers may are many, and contrasting, so how are different the types of e...

Welcome! Well only few questions... right? There are many answers, and all us will be able to give you. - I propose a book for you: "Making a Stirling Engine", by Andy Ross. - I propose also a bit of study about how the engine runs. When you know how the engine runs you have itself many an...

Dav, the function of the regenerator is the same in all types of Stirling engine, heat storage, and return. Each has chosen several systems, trying to reduce the dead spaces, which are the ducts where there is no useful thermodynamic action. In small motors have regenerative function the walls of th...

Welcome Dav !!! Gamma architectures may be are different, pistons may be are parallel, and regenerator coaxial to displacer. Wikipedia scheme do not resolve all possibilities, are examples... Many and many architectures are been explored and tested. You have to be more documented on what was yet don...

Yes atmospheric is unpressurized; the engine runs with compressions and decompressions done by heat, when the average of pressions is the atmospheric. Excuse my incorrect translation of atmosferic = atmospheric) This challenge comes from the fact that someone, in forum, wanted a "real" pow...

I correct myself: between is used as regenerator; (not displacer..sorry
F

Ian Negative: I know that the tube (between) are used (in part) as displacer, but with diameters of 360 mm (but also a lot smaller...), you have to connect the circonference of the hot heat to the (lateral) tube-regenerator and then the tube-regenerator to the piston, this involves other tubes and d...

Ian, In Ross Joke the motor piston stroke is smaller than the displacer one; with smaller stroke is necessary larger diameter of piston to conserve 1:1 rapport. The geometry of displacer and and piston is fixed in consequence, and so they (displacer and piston), also if parallel, (very good!) are qu...

Ian I do not agree, the two cold pistons allow a perfect location, with almost reduced transfer ducts (dead spaces), which, in a large engine are really deadly (are feet of tubes!!!); with the frictions (already optimized) to have three rods is not detrimental, in fact is quite the contrary ... each...

About a "Medium technology level" (not too high), feresenn with "today not too high level materials", Ive done a draft for a 5000 W engine. I propose it to you. - Alpha parallel architecture. - One displacer, twoo motor pistons/cylinders. Displacer dia 360 mm Displacer stroke 260...
