Jonova Engine-Motor

Latest update Jan 26 October  2016.
added working link to the Arizon university website about Jonova engine.

I have recently been educated that  “” neglecting heat transfer, combustion transients, and intake/exhaust restriction; all positive displacement engines having the same pressure bounds and same displacement will produce exactly the same power.   The energy produced by a positive displacement is given by “”

This means that the combustion gases don’t care inside what kind of engine they are in, what is important is the initial and final pressure and temperatures that you are able to operate at.

The higher the initial combustion pressure value and the lower the exhausted temperature and pressure values the more powerful and efficient your engine is. regardless of geometry or architecture of engine.

So the architecture or geometry of an engine doesn’t really matter or affect  how much power or efficient the engine is at extracting workable energy from the fuel.

by the way the Jonova has and will continue to fail. don’t waste your time or energy, i will try to explain why later.

 

 

The rest of  this page and in fact all pages need to be scientifically reviewed by real

scientist and engineers. 

Please ignore what i have written down and enjoy the links.

I don’t think the video above of that architecture will ever work, the air or combustion gases have no reference to push against, the next cycle start too early, there is no room for the gases to expand, the rate of increase in work chamber is too high.

Recently i got  to do some calculations on  how much torque such an engine should generate,  I got 2270 N.M for a 8 cm rotor radios, as  combustion pressure came to 145 bars.

I am not sure if the numbers  are  correct,  I think they are, check the help me build my engine page.

Two Russians in their  garage have  an actual running JONOVA like engine. CNCed and RUNNING.

And it appears  they have actually solved the problem of sealing between the main rotor and the circular value.
Watch this engine running.

click  here is their website . 

or click   here are the advantages of the Circular engines according to Igor
back to the Jonova engine.

the animated JIF pic below is taken from another site . click to visit it
The design isn’t new , and as far as I know  impossible to seal .
Also the flame is slower then piston speed, i.e there isn’t enough time for pressure to build up.
The rotary valve cannot be sealed with the main rotor no matter what system you use.
The chamber for combustion would take 50% of the pressure of the burnt gases i think.
but it is a nice demonstration of the concept to circular complete torque large expansion ratio concept.

Above picture animation of the “The Eve Rotary Engine: 1825” which is a simple Jonova LIKE motor engine .

you can click on it to go to original website which has lots of Circular engines.

also here is a quotation from the original site ” This animation follows all the contemporary drawings in showing the cutout in the little “revolving-door” as a portion of a circle. You will note that this gives a poor fit with the protruding vane of the rotor as it moves through the cut-out.
If this is correct then for part of the cycle there is a serious leakage path directly from inlet to exhaust, with dire implications for the efficiency of the engine. This is not the only engine in this gallery which shows this fault. “

Here is a real life model its russian attempt

another model

The Jonove engine is part of a huge family of internal combustion engines.

where there is no connecting rod between the piston and the torque arm(disk), and the piston moves in a circular path or toroidal path that forms both the combustion chamber and pressure chamber.

This lack of connecting Rod leaps the thermal efficiency of the internal combustion engine system from 45% (large & heavey Compound engines for electrical power Generation not mobile) power of the Diesel Reciprocating engine to a staggering 60% for Circular engines with much less with .

The Name Taken Jonova is taken from one of the inventors of this type of circular engines named
John NOWAKOWSKI.

The Jonova Engine isn’t new design at all , there are hundreds of the “Jonova” like engine designs , it is only because of the The Arizona Arizona University’s work that it is becoming popular . click on the following pics to go to web site

You can go to the UA site with the original artical by clicking on any of these two pics.

This engine design goes back a hundred years (many patents exist) i have done a great deal of servey + internet.

Here is Text from one of the Jonova Websites.

The project led to the development of four possible project phases. Phase I involves developing an animated CAD drawing illustrating the motion of the engine while providing enhanced visualization for thos unfamiliar with the project. Phase II consists of developing a stereo lithography model for dynamic design validation. The completion of Phase III is a working metal model run on compressed air. Finally, Phase IV is a hot, fuel-burning engine. This was an optional stage, to be completed if time premitted. The current design predicts an ideal engine capable of producing nineteen horsepower at 3000 rpm. This design incorporated internal compression, which ultimately results in a more environmentally friendly engine, since less fuel is required to produce the same power. The original aim of the team was to build q hydrogen burning engine. Time, safely and sealing limitations made accomplishing this highly improbable. The hardware for the final prototype, an aluminum engine, has recently been completed due to the generous donation of machine time and material from the University Research Instrumentation Center. This final prototype includes bearings, cooling channels, spark plugs, coil, distributor, carburetor and other equipment necessary to reach a fuel-burning state. Phases I, II and III were completed that resulted in a successful design project.””

  1. Maaaan, you know there is such thing in the web like search engine, http://google.com if you don’t, go there to understand why this post is bullshit

  2. The Tri-Dyne engine that was shown in Popular Science in the 60’s is a variant of this engine. I would like to see how this works as a compressor, or as an expander, (i.e. steam engine).

    It may be better to use this as gas expander, the engine wouldn’t have to deal directly with combustion.

  3. We have invented a more powerful and effecient internal combustion engine which has 333.3 horse power and does up to 8000rpm. It can use any kind of fuel, economical, cheap and has very few parts. If you are interested, just contact me and I can give you details.

  4. I don’t understand why you are using Jonova as a generic name for a rotary engine. This isn’t the first engine of its type. It’s not even the first time a major university has looked at a rotary engine. It will probably never make it into production, nor the Canadian patent from which the UA design was derived. It doesn’t appear to solve the sealing problems associated with such engines. In short, there is no reason to fixate on Jonova.

    • Dear Sir Mr David.
      Thank you for posting on my blog.

      The reasons I use this name even though I have hundreds of patents with the same configuration are as follows..
      As I started to look into true rotary engines, this university rotary engine was the first of its type/configuration that I saw/found, it had a specific name and some pics and a prototype ,
      And since I had so many different patents of other rotary engine configurations/designs , and I had a naming convention problem and to give those engine designs ,and to give those students credit for the work and creativity working on the engine , and n creating the name for the engine -yes they are the ones who named it- by calling it the using the name they used ((Jonova)) was my way to solve all of the problems and also to give credit to the original inventor and the students, also the name is catchy.

      As you have stated “”It will probably never make it into production, nor……such engines “”

      Yes you are right it WILL NOT and WILL NEVER ever reach commercial production for many reasons. I if you want I will try to explain.

      In fact almost all of the concentric engines i featured or are being investigated will not make it commercial.

      So…. I do Feel that I might be misleading people by not putting the downfalls and short comings and practical and engineering impossibilities these engines have/are.

      As for you words about Fixating on the Jonova , I am actually not Fixated on it, even those the Russians have built one that is working and has partially solved the sealing problem.
      It is just that I have tried/try to gather as much info as I can about these concentric rotary engines and share this info with the public as it is, I try/want to be as neutral as I can ,
      But for some reason the public is so fixated on this type i don’t understand why, might be simplicity or the animation I have no Idea why, this page (Jonova) Gets almost all the hits even though there are much better designs out there and on the pages.

      I hope I answered your questions , I hope you like the answers , and i would enjoy discussing any thing about them engines.

      I thank you again for protesting here, and reading my into my site.

      Thank you Mr David l wallis and Best of regards.

  5. […] 6 minutes and collect data. That's not research. I'm talking about things like this: https://dreamer3000.wordpress.com/page-3/ But my school is not doing research on engines, so if I get involved with a professor I'll […]
