Hi everyone this is my first post on the forum because I need some help.

Anyway here is the shpiel... my father has designed a revolutionary new rotary engine design. It is A LOT more efficient model than even the RX8 model. It should be more powerful and have much better fuel economy. He has had this idea patented, the problem is we need to get this idea to Mazda so that they can consider buying it for future versions of the RX8 or whatever they maybe be coming up with. It cost over 20000 dollars to get it patented so making a prototype without some extra fincancial banking would be difficult. I need some contact information for people at Mazda. You can private message me.

The Renesis is at its core a heavily tweaked Wenkel Engine instead of tweaking this takes the engine to the next generation.

All this may sound odd I assure you I am not a troll. I am currently an engineering student entering my last year of study and my father has both a bachelors and masters degree in engineering along with many years of experience.

Thank you again for any help you may provide.

I would prefer to talk to someone with some power at Mazda rather than some customer service rep.

 

If it's patented ... could you give us the patent number so we can look it up?

 

We are currently in the process moving homes so I will have to wait till everything is unpacked before I can give it.

 

The other thing is I wouldnt mind consulting other companies but I doubt they would scrap all their engine manufacturing to go rotary.

 

Wow, there are quite a few patents for rotary engines and the like.

Check this out.

That is a search for "Rotary" and "Engine" on the U.S Patents and Trademarks site.

 

You misspelt Wankel, and if you are looking for Angel money that's one thing, but I doubt if a manufacturer like Mazda would be interested in scrapping it's engine design, which it no longer pays licensing fees for, for an unproved design, which has no real test data since you don't have a prototype. Even for a troll, this would be a long row to hoe.

 

"Misspelt" is not a word.

 

if you had a patent you wouldnt mind handing out the number thats why you have the patent, it makes it illegal for anyone to steal your idea...just who are we kidding here?

 

*sniff* *sniff*

I smell a troll.

 

But, he assured us he was not....

 

It would have cost you 1/10th of that amount if you file yourself instead of through a lawyer.

 

I won't doubt that emporer's father has an interesting design patented, but why try here to find names at Mazda. Part of actually making money from your idea is selling that idea and unfortunately it takes much more to sell a new design than posting on an internet forum.
Actually if you do have a huge improvement over the Wankel, other car companies may be the way to go. Mazda has spent untold millions developing the Wankel to where it is today and never has tried one of the other rotary designs (that I know of). I do not see the company retooling to produce either 2 lines of rotaries or scrapping the Wankel in favor of untested technology. Where another company (lets say Mercedes--who was interested in the rotary before) might buy the design and do the R&D.
As far as trying to get to the right people to sell your design to in a major car company; all I have to say is "good luck". Be prepared for lots of disappointment before you hit it big.
BTW, what kinds of factors makes you so sure this is a better design than the Wankel. Isn't it kind of early to say that when you can't get a prototype together.

 

Hmmm. Usually when I have an idea that I believe will be valuable to the company, make them more profitable, increase revenue or whatever, I normally put together a proposal complete with busness case and ROI, and contact a senior executive. Such as

James J. O'Sullivan - President and CEO
Robert Davis - SVP, Marketing and Product Development
Richard Valenstein - VP, Finance, Systems, and Administration

unless it is a gas/electric rotary you are wasting your time. nobody on the planet would invest/purchase in anything but that.
we are getting 20mph tops with a great motor. unless yours is around 40mpg there is no chance. joe

 

isnt ford only a 33% owner of mazda...just curious because im not too sure they have a controlling interest

 

Ford owns 33.4% of Mazda. That constitutes controlling interest.

Ford used to own 24.54 percent, but when they raised it to 33.4 percent, part of the deal was to make Henry Wallace Mazda's president.

In case you don't know who Wallace is, he was VP at Ford at the time.

I'm not sure if Ford can own more than 49% of Mazda though, due to Japanese law.

 

Patent Link

Click on the pictures to understand how it works. Anyway if you guys know of anybody who could possibly manufacture a prototype that would be great. I am currently looking at some prospects but the more the merrier.

 

I still smell troll, but I could be wrong.

What is the point of novelty? It is easily ascertainable if I order the file wrapper, but don't feel like spending the dollars to do so.

But the novelty is somewhere in here:

"a plurality of vane subassemblies, equal in number to said extensions, adapted to mount within the chamber subassembly such that each vane subassembly independently pivots about its own pivot axis, each vane subassembly including a vane member forming a compression/combustion subchamber between said vane member and the surface of said cylindrical volume, each said compression/combustion subchamber being isolated from each other of said compression/combustion subchambers, and in the case of an internal combustion engine each said compression/combustion subchamber functioning to both compress and combust fuel therein, a portion of said vane member extending into a corresponding one of said extensions;

a rotor subassembly situated within said cylindrical volume and permanently isolated from each said compression/combustion subchamber such that the rotor subassembly is not exposed at any time to the contents of the compression/combustion subchambers, the rotor subassembly including a drive shaft aligned along said central axis, and a rotor blade mounted on said drive shaft, said rotor blade being formed such that the rotational position thereof corresponds to the pivotal position of each said vane members"

I'm thinking one of these:

1. each vane subassembly independently pivots about its own pivot axis

or

2. a rotor subassembly situated within said cylindrical volume and permanently isolated from each said compression/combustion subchamber such that the rotor subassembly is not exposed at any time to the contents of the compression/combustion subchambers

2 above appears to greatly reduce emissions. One question is, if a prototype has not been built, is this enabled? Also this patent issued in 1990, don't you think Mazda is fully aware of this to make sure:

A. they don't infringe; and

B. they aren't passing up valuable advances?

 

I'm glad that your dad wants to get his design out there. As an engineering student myself, I understand that it is hard to market new things. Unfortunately, Wankel-type rotary engines have serious disadvantages, such as heavy fuel consumption, low thermal efficiency, etc. My thermodynamics teacher told me that the Wankel rotary engine was more of a novelty item, which is why you don't see them in any other car today except the RX-8. I am impressed by the design you father came up with. I couldn't even dream of anything like that. The closest thing I ever came up was a modern version of the RE10X, which I believe was a direct-injection rotary engine that Mazda experimented with some time ago. I've read some SAE technical reports on a John Deere GDI rotary, and the results were impressive, even today (the report was written sometime in the 80s). Good luck with your project. If you need help finding a manufacturer, I would be glad to help you in asking around .

 

Thanks for sharing the patent with us. I read it with interest. The design is indeed impressive.
However, there are so many clever 'rotary' engine patents that never took off that I would not bet a Cent (that's a hondredth of 1 Euro) on it.

 

It says filed in 1989, wouldn't that make it a bit old? Also as said there are many interesting designs, Mazda have extensively developed this engine, I doubt they will switch rotary engine types after all that R&D. I would reccomend contacting Photon, because they seem open to these new engine types and I do believe they bought out Lotus and are on their way up. Anyways you might want to send that link to Rotarygod, I think he might like to read that for fun.

 

Photon? What is their full name? Do you have a link?
The idea maybe ten years old but in the world of engines I dont think its outdated considering the V type has been around for such a long time. Even the Wankel is a very old concept.
