Increasing full mileage

My-SS · August 16, 2005

With the high prices of gas today, I am looking for ways to increase my fuel mileage.

I remembered that back in the '80's Smokey Yunick built a Pont. Fierro in which he turned the gasoline into a vapor and with the use ofa "turbo charger" he was able to keep the inake system pressurizied so that the vaporizied gasoline would stay in the intake system..He not only drasticly increase fuel mileage, but also had a healthy increase in power..A by product was drasticly lower emmisions...MOST of these gains were from the fact that the gasoline was changed from a liquid to a gas vapor..The turbo had just enough boost to keep the intake positive charged so the vapor would not escape.

I'm wondering if I could use maybe NOS nozzles with a fuel injection system and inject vaporized gasoline into the cylinder much like the OEM system does now.

Or maybe use some parts of a propane unit

I'm just thinking out loud here and appreciate any input..

I have a complete 5.3 that I may mount to a test stand and try and develope something..

Go for it. Everyone likes a mushroom cloud. Sounds a little risky. Just be sure you stand back when you light it off.

I actually like people who think like you... I think about this type of stuff all the time.. If I was independantly wealthy, I be an inventor!

I Always thought about this EXACT concept! Even as a teen... it it were just to prove the experiment I think it could be easy...

But to make it work on a vehicle that needs to change the A/F as more power is needed would be difficult since the fuel is already atomized..

Unless.... there were 2 canisters.. One with say a 14.7:1 mix and another with like 12:1 for acceleration.

The motor would have a dual stage Throttle body.. say at 40% you got the 14.7:1 and 41% and up to WOT you got the additional 12:1....

The canisters could have air swirling in them with a big fuel injector at one end and the O2's would determine ho much fuel got sprayed in there.. once they hit the right A/F the injector would shut off.. I bet it could be made to work..

As mentioned earlier.. this is the makings of a great big bomb... certainly powerful enough to mushroom cloud the truck...

If you think about it.. there are tons of Propane powered vehicles around... but I think that cost more than gas...

Things that make you go Hmmmmmmmmmm

Ahh, good ol' Smokey Yunick! The memories that brings back...

Was that his adiabatic (sp?) engine?

By golly, I got the spelling right! Here's an interesting link: http://schou.dk/hvce/

Let us know how it works out!

...so I take it the idea is to keep the gasoline in a vaporous state, without it condensing back into a liquid, and at the proper ratio to air. Carburetors were pretty sloppy, but I wonder how close we're getting with fuel injection?

My thought is that there is only so much heat energy available in a gallon of gasoline, and you can't get around the fact that it takes X amount to shove your vehicle down the road at a certain speed. Plus, you have the low efficiency of the present internal combustion engine, which works by heat / expanding gas.

On propane conversions, the propane mixed into the incoming air already is a vapor state, and yet vehicles with this conversion get less MPG than when running on gasoline. Why? Because there is less heat energy available in a gallon of propane vs. gasoline.

Quite some time ago, someone invented a variable venturi carburetor, and legend has it that it produced amazing MPG. It was named the Pogue carburetor, after it's inventor. I haven't done any research on that subject, so I can't say any more about it, but I do know that Ford made a variable venturi carburetor of some flavor in the early 80s. It was quirky, if you ever drove one, and was a pain in the b*tt to get one working just right.

Intriguing idea, but my hunch is there needs to be gains made in the efficiency of the engine. Good luck.

here's a good read for you about why that carburetor wasn't successful. The idea was to use heat and pressure to introduce a dry vapor into the engine:

Although the person that wrote the article has good points, we must remember that in the 40's no one would have believed that you could heat food in a small box on your counter in a fraction of the time. People who try ideas like this and keep at it will eventually come up with something of use. There are opportunities out there that we do not know are possible, what we think of as fact today may be proven fiction tomorrow. I say go for it, you may find a way to increase the milage on all of our gas guzzlers!

Whoever wrote that article is a CRACK ADDICT... I know there was some good info in that but it was written by someone who had NO grasp of the english language nor used a spell checker.. It was very hard to follow..

Plus he throws in random thoughts and statements like is has ADD also...

So accordingly, thats why the diesel trucks get better fuel mileage? Much higher compression? And why you can get more mileage using higher octance gas? Is there a certain pressure in which gasoline will ignite without using a plug?

PELICAN · August 17, 2005

I'd say go for it. you could be on the news for creating a way to keep the gas guzzlers on the road , or you could be on the news for creating a rather large explosion.

Diesels get more mileage because there is more heat energy in a gallon of diesel than there is in gasoline. Heat energy is the name of the game.

You only get more power out of high octane gas when you have higher compression and an ignition advance curve to take advantage of it. Higher octane gasoline resists spontaneous combustion under compression more so than regular grade, so you can squeeze it harder before lighting it off and thus get more bang for your buck, so to speak. It would be hard to say where a given pressure that high octane ignites, because I'm sure temperature and the design of the combustion chamber have much to do with it. That, I understand, is part of the excitement and hoopla being made about the hemi head; they can run higher compression without knocking (comparatively speaking), and the charge is more "focused" on the piston than with wedge head designs.

Someone correct me if I'm mistaken but that's how it was explained to me.

i hear that.

Aliens once gave me the knowledge to get 50 mpg from a large vehicle, but the night before I was to go to GM to show them my discovery, the aliens took the knowledge away from me. They told me the world was not ready for this kind of invention or knowledge. When we as a people can get along with one another, they will return with this and other methods to improve our lives and the keep the earth productive without depleating it.

and you really belived that?

i actually talked to a guy who works at the livermore labs in cali and their labs worked on a gas engine which had no spark plugs. they actually were controlling the cylinder wall heats so well that they could create an evironment for combustion.
