exxon / mobils 100mpg carb

[nypdwb1]

Standard Oil which has become Exxon / Mobil owns a patten on a carborator that gave cars of the 1940's a 100 mpg. They still own the patten, no big secret why they keep under wraps. They make 30,000,000,000.00 in profits and keep a carborator thatwould give all of us 100mpg.??????????

[MorningGaser]

Is this urban myth? How do we know this is true? What are your sources?

[Coyote X]

patents expire after 17 years. You can also do a patent search and look at any patents that have even been granted since 1790. So if there was a device patented in the '40s you can now legally manufacture and sell it all you want

[kps]

A patent from the 1940s would have expired by the 1960s, and we'd have a patent on file showing us how this magic carburetor worked.

Carburetors are gone but the fuel-vaporization con angle is still around.

I thought you could tweak the original patent just a bit and still keep it / er, renew the patent. At least, that's the game big drug companies play.

Seems like we are getting our chain yanked a lot lately. This guy, spinningmarkviii, the free tank of gas guy, etc...

It's an urban legend that came out of the old Shell mileage competitions. They'd take something small like an Alpha, scrap the tread off the tires and inflate 'em up to whatever psi, shave the heads for more compression, run the carb lean, use pulse and glide, etc... to get high mileage out of passenger cars. Well, word does get around, but by the time most people hear it, it's gone from some guys screwing around and getting good mileage to a 100mpg carburettor. The peak right now seems to be about ~100-150mpg@ out of something w/ the same size and aerodynamics as a Honda Insight.\

Iirc, someone else can still make the original thingy per the original specs after 15 years, but a company will time the filing of patents so they always have exclusive rights to the latest and greatest version.

When gas prices go above $3/gal (U.S. Avg.) -- stuff like this comes out of the woodwork...

PISSSTTTT

I have one of these carbs on my 1970 Honda Mini Trail.

And, if any individual wants to make it for his or her own use, he can.

I did hear, probably not true, but that mysterious patent was for fuel inection vs carb's. If that was true, everyone is using fuel injection vs carbs that I know of. Does anyopne still use carbs?

No, Exxon owns all the good patents. ;-)

Pretty sure that no new cars in the first world have carbs...

[SVOboy]

Some scooters still use carbs,

I only know about honda, but they are going to be phasing PGMFI into all of their powersports by 2010.

[Mike T]

I have one of those carbs on my bicycle. Seriously.

LOL

[Ryland]

I love that about patents, that anyone can do a search by patent number, or name, or patent type even I think, alowing anyone who would like to make one for them self to read thru it, look at all the sumited drawings, and even make one for them self, you just can't make a profit off it

[kwtorbe]

I bet it is a single barrell 20cfm that will let your motor have a whole 9hp and go 35mph after 2 hours of accelerating.

We could all get 100mpg if we strangled our motors and drove 35mph everywhere.....

Besides that 40's engines were primarily flatheads that had horrible quench, compression ratio, spark, timing, and everything else for that matter. Generators took alot more power than the common alternator too...

[Ford Man]

[QUOTE We could all get 100mpg if we strangled our motors and drove 35mph everywhere.....



I would be willing to do a lot of my driving at 35 mph if I could get 100mpg vs 45mpg driving 50-55.

Shush it's not the evil oil companies it was the U.S. government that destroyed the original carb and put the patent in the CIA's vault for safe keeping. The possibility of a 100 mpg carburetor out there the government would lose billions in fuel taxes.

If they did have something like that, the party that made it public by saying a government sponsored scientist hired by the president would probably be able to use it to get back into the election chair(the party anyways) for a long time.

An electronic carb CAN get better mileage than fuel injection. Carburetors are emulsifiers while EFI just 'injects' the fuel. The late 80s Corollas had electronic carbs and they did fairly decent. Just about as hard to control mixture as TBI so you would really need 4 small ones to even match EFI today.

[Sludgy]

I think you're talking about the Pogue carburetor. It was supposed to pre-vaporize the fuel: http://www.rexresearch.com/pogue/1pogue.htm

This idea has some merit: By vaporizing the fuel, the engine could run extremely lean, increasing the completeness of combustion while simultaneously reducing pumping losses. This is similar in concept to Smokey Yunick's turbocharger system, and to recent HCCI engine designs.

Still, it's hard to belived that a Pogue carburetor could move any vehicle 100 miles on a gallon of gas with the low compression engines of the day, unless top speed was restricted to say, 25 mph.

[ALS]

I was just making a joke. I thought the at the end would tip you off to my intentions.

[GasUser]

100mpg carb...........yea, but what does it get going up hill???

This is a really old thread - how did this get dredged up?

It would appear that FordMan is responsible for res'ing this thread, unless there is a deleted post in between the last old one (circa May 2007) and his.

[Big Dave]

This has to be the all-time champion of evergreen conspiracy theories. I first heard this crock in the early 60s. Of course, never the first bit of corroboration.

I didn't look at the date on the thread, someone must have made a comment and then deleted it. It came up as a thread that had a new comment.

[markweatherill]

Oh heck! It's certainly pervasive. I was in a training session at work on the subject of environmental issues, you could have predicted (and of course it happened) someone piped up stating that some friend's relative, while working for a big automotive concern, happened to invent a carburettor that got 100mpg or doubled fuel mileage or some such... and all rights to the device were snapped up by said big company never to be seen again.

So do it, already!
My ex-Passat (still in my name, but now it's 'hers') averaged 48 mpg in "normal" driving, but 80+ when really trying for good mpg and keeping speeds down to the 35~40 mph range. I strongly think your 45 mpg could be brought up to mid 70's by dropping your speed to mid-30 mph and concientiously driving for fuel frugality. Then you could claim to have a derivitive version of the non-existent big-oil-supressed, miracle mileage air /fuel mixer. Maybe not 100 mpg, but halfway there for absolutely free, no licensing, no infringement, no labor.
The down side is needing 14 hours for a 500 mile trip, now THAT gets tiring quickly.

You can get 100mpg with "Steam cracking". Do it in real time. 1 gallan of gas don't just = 48 Horse power per hour at 100% engine eff.!

Ok, I googled "steam cracking" and read the wikipedia article, and I get that steam cracking is the process of breaking down large hydrocarbons into smaller hydrocarbons. What does that have to do with automobile engines and their efficiency?
