Hi Ian SC, I do agree with anybody that free piston can be dynamically linked to displacer,with a Scotch Yoke you have an easy drive for trials.Thankyou for explaining me the ringbon mechanism,you do not say why the electromagnetic field to move the displacer by outside coils?then probably Beale sai...

Dear Ian, Please accept my apologies for so colloquial reply on your enquiry.We have dynamic linked pistons based on fluid mechanics and Inertial dynamics only.If you apply Lagrange mechanics,for ex.solving all eq. simultaneaously,regardin compressible eq. of working fluid, then you´ll be in displac...

Welcome all of you new Members,friendly,to this wonderfull Forum on Stirling Engines. My first comment is that this challenge to be better than IC engines needs in my oppinion a multidisciplinary effort, and all of you are a potential plus to? the main target,not defined yet,meaningfull is to reach ...

Dear Colleagues, I read in this Forum something exiting, in gamma this ratio can be handled fron 1 to 10!!! I have an enthusiastic friend fan of SE, he doesnt know,by the rule of thumb and space his gamma,2 displacers vertical and 2 free small pistons rubber sealed, is running quite well. Lets find ...

Dear Friend, 1.-If you find some statement against the increase in Compresion Ratio,except max temperatur increase,please let me know,CR is fundamental to get an important increase in power output. 2.-If you can confirm me ceramic coating insulating wall, adiabatic,I´ll be gratefull,so we can dream ...

Hi buddies, 1.-I remind that 1.5 is a variable coeficient with influence in Diameter ratios,hot and cold. 2.-Sirling wrote L/3=stroke, L=3 D, 3D/3=D=stroke it means displacer zone ,I understand the drum displacer Volume swept=o,785 Dexp3,In L length of drum,1/3 cold,2/3 hot. My above colleague confu...

Hi you doing colleages, Thankyou for sharing knowledgements on S.E. of different configurations , more than 3. I´ll be short respecting others space. 1.- In Alpha, the optimum ratio between Volume of power piston have been stated as Vp x 1,5=Vc, Vp piston power, and Vc is vol. compression. This is n...

STIRLING ENGINES EDUCATION. The historical event that Diesel cycle and Otto cycle, between others like Brayton,meanwhile Stirling Engines, external Combustion in almost 200 years is still fighting to take off,call our attention in the perspectie of the last 50 years only.In next posts we want to com...

Dear Colleague, Your question is interesting,Same Stirling let us simple ratios around, but I´ll retransmit a recently posted ratio based on piston work swept vol cylinder, x 1.5=swept vol. of Displacer, some simple mathemathics establish the optimum ratio between piston radius and displacer radius ...

Dear Mr Norris, Probably you are using a language methaphoric,or are yuo kidding. Yesterday I posted you in detail,sadly I pressed a botton store the mail!I am sorry. This time I´ll be brief. 1.-The misconsideration of this marvellous Stierling,any type,that now is reviving a new wave, it was scienc...
