Beta type Kovács/Manson engine with regenerator

Here is my new Beta type, cold side ventillation Manson engine in an animated GIF.
The crank is so simple, but works well.
Less friction on the sealed parts as same like Beta Stirling without any gears! :)
The hot side ventillation is possible too as mine first construction.


The engine has regenerator and this construction can work with flywheel or free construction also!
So, if you have enough money, time and tools for this engine, just build it and call itt Kovács Beta type Manson engine. :)


Here is a normal crankshaft version with original Manson cycle ventillation 

and hot side ventillation




GREETINGS!

Welcome to my new site!

This blog will show you some tips, tricks, and some new research and development results for hot air engines.
Specially for Manson and Ericsson engines.
I know these hot air engines are not really popular as like a Stirling cycle engines.
Lot of time I heard in the last 6 years: "Manson and the Ericsson cycle engines are was dead end of the hot air engines."
When I asked: Why?
The Ericsson cycle is one of the best caloric cycle.
The Manson engine is one of the highest torque hot air engine.
They has open cycle. 
Is that a problem? Not really! :)
I have new practical inventions for these engines! 
Are you interest it?
Then subscribe my youtube channel (BladeAttila's youtube channel) also follow me on my blog here.

Who am I?
I'm Attila Kovács from Hungary.
Chemical technician and CAD/CAM/CNC operator, also service engineer in the Hungarian TECAN distributor's Ltd.
The hungarian Group of Stirling friends community's leader on a forum also on the facebook.
Few years ago we created an overall hungarian hot air blog with my friend Simi112 (Simi112's channel)
We tried to collect and categorized all of type hot air engines from the last approx. 200 years.
That was a big challenge! :) 
That blog is the biggest, categorized collection of different types hot air engines in hungarian language.
In this year we start to translate some popular pages to Engish.
That is under construction now! 
Coming soon! 
Be patient!  :)



Sketches from hot ventillation regenerative Manson engine




Regenerator

The original Manson engine hasn't got regenerator, but a small gap between the displacer and the cylinder.
This is a bad regenerative parts, so I tried a simple regenerator in my first engine.
My first engines had hot side ventillation!
Remember, the original engines had cold side inward, and hot side outward breathing.
The Rupp engines had cold side ventillation without regenerator too.
What's the different?
The original engine get cold air from outside, no preheating!
It has slow and bad heat exchange, because the contact surface was small.
I used a steel tube for breathing. It was a preheater also a preregenerator.
The preheated air easier expand when the displacer-regenerator (secondary) move up.
The heat exchange's time shorter, the engine has higher speed, also performance.
The engine has 250 ccm volume, and it was very low budget construction!
Easy to build and so simple with only one self controlled valve.
I know it is useless for real power, but what can produce a professional one...? 

Here is my little boy's firs run, on denatured alcohol burner:
