i think that is creating to much friction. you can create the same pistons patern just with a crank and conecting rods. with less friction. (i think)
-
@lapere71 That's I find out in practice also...
Better to have something out of machine if it is suited to job and machine is long lasting - also most of the energy I´m losing when heat is not even entered the engine and it's working gas.
Got some slow work going on with continous torque, less need of flywheel, stress and still overall simplicity with inaccurate manufacturing robustness, easy materials etc... These should be good for a reliable subsystems where "lost heat" is used anyway...

@railrdr523 Yes.This only has ideal gas isochoric transfer to the cold cylider after expansion. Do not give up, power not the most important :)
a.) power is a function of charge pressure and working gas. Pressurize 200bar with hydrogen and you have a power.
b.) this is the reason of my work. of course they are inefficeint. gas is wrong place in trad. 90deg piston engines.

@lapere71 very very nice sounds like something that would take me a month to figure out u have really took the Stirling engine idea and made it efficient way more efficient thank you
-
@railrdr523 The reason of this mechanism is solve both a) and b). With the mechanism, the stirling will produce a lot of power and it will be much more efficient.

Do you think that high compression ratio is the main way to do and get advantage with these many types of heat machines (work done on compressing the working gas on hot end)?
In my opinion this help heat flow in hot end only and adds stress to mechanics...
Nice real work and efforts presented here, thank you.
About this I agree with a comment of "onecraftydude" about two bearings with lever-springs or similair taking out the hitting noise making gap for smoother and long lasting operation...

@358Eki Low compression ratio is better than high in striling cycle machines.

so... it's been said before, but it seems like a cam like that would have alot of friction compared to a traditional crank. how much friction is there, and would it need an extra flywheel?

@AngryVGFur can't solve friction problem with flywheel. Flywheel is only energy reserve and it cause more friction.

not much different from the old swash plate idea, just a cam instead of a plate!?
Axbent 2 years ago
@Axbent no, no, n, cam is not a idea. Idea is that cold cylider volume is zero during expansion process and hot volume is almoust zero during compression process.
