Y'all check this out. Pretty neat way to run an engine.

I did not go to that site dial up takes too long to upload a Video.

However, I believe that this is not actually a new Idea just like the Common Rail Diesels Fuel System is not a new idea. Apparently the Idea has been updated.

When gasoline Engines first came out the Fuel was sort of sprayed, dripped or otherwise passed onto a warm Plate before entering the Engine.
In the old days you used something like a Blow Torch and heated up the Plate before starting the Engine. When the Engine Started the heat of the Engine kept the plate warm.

That was somewhat OK for Stationary Engines.

Back in the 1970s they were looking into ways to use sound to vaporize the Gasoline. What ever happened to that idea.

I think part of the Vapor issue is that it is easier to meter the Fuel as a liquid that after it is a Vapor.

Also when Gasoline is a Vapor it is extremely easy to ignite making it a little dangerous.

I have heard the horseless carriage engine ignition system was known as a 'hot-tube ignition' as in the gas was sprayed, like you said, on a hot tube.

The spark plug was well known then but it could not deliver enough power to fire off a gasoline charge. In 1903 BOSCH came out with a magneto system that could fire a spark plug with the needed power and the hot tube was soon on the way out.

The problem many vapor systems had in the 70's was the flashing of the gasoline.

Controlling the mixture was too difficult with the tools of the day and if the gasoline flashed due to high temps it was like a bomb going off under your hood. A big bomb, too.

There was also no way to control the rapid increase in flow needed for acceleration. They were easy to flood out and then you stalled. And yes, there was a big problem with vapor lock due to the heat involved.

I knew a guy that fooled around with all of this back then. He was a pretty smart guy when it came to mechanical things but he never could get it to work as it should.

Smokey built one too.

Cool! Smokey was one heckofa guy. I have his autobiography. It is a very good read.

very interesting indeed. I am going to try it on one of my mobile gasoline powered generators

This is pure unadulterated BS. There is simply not enough energy in the fuel to support those claims. Besides, gasoline is burning as a vapor, even when introduced as a liquid. Were this claim true, the engine's thermal efficiency would be over 100%, which means that it would absorb heat, not give it off to the exhaust and cooling system. The engine would actually get cold at that level of efficiency.

Back in the 80's there were seminars on the 200mpg carburetor and this is pretty much where you end up after looking at all of the information. If you can vaporize gasoline into a dry vapor, ideal gas state, you end up with something like propane or natural gas. Compare BTUs.

Fractional distillation was an issue. You can split gas into fractions and end up with waste products.

There were some articles on vapor injection also. I never tracked those down. If anyone sees them I'd like a look see.

Fuel prep systems on jet engines are worth a look. Same for marine engines, old books are cool.

That said there is room for improvement. Start the violins and get to those deck chairs, save the Titanic.

I had a vapor injection system on a big old GM car back in the 60's. They claimed to give you better mpg but I never saw it.

The whole thing was..... A large glass bottle; think pickle jar. Water at 90%, isopropyl alcohol at 10%, an adjusting valve and a suction line hooked up to the PCV valve line. The suction of the engine created a low pressure area in the top of the jar and the adjusting valve controlled how much air was let into the tank through a pipe that ran to the bottom of the jar. Lots of bubbles came out of the bottom of the pipe and the mixture of air, water and alcohol were sucked into the engine.

This resulted in a cooler running engine that was supposed to do all sorts of wonderful things. I did notice I could run mid-grade fuel when it came out and not premium, so it did enhance octane in a way. But all the other Unicorn effects? I didn't see them. I understand some racers ran them, so they must have had some use.

When states went to smogging your car during an inspection they all had to go since they were not factory installed smog items.

Seems like when he toasts his bottom end running lean, and realizes how much fuel he could have bought when he has to replace his Camo-Kota it will be obvious it was a waste.

He also removed his air filter element, a very effective flame arrestor between the engine and the bomb he has mounted to the RF fender.

LOL

had y'all going didn't I?

I think the one Smokey built actually did run some.

I do think it is neat and there probably is something to it. Complete vaporization is worthwhile and has not been a priority with engine manufacturers. We are still riding the tails of the cheap fossil fuel age.

If you underheat the fuel you get fractional distillation and if you overheat the fuel you get carbonization. If you can heat the fuel to a dry vapor without heating the intake air excessively and get it all burned before the fuel condenses you might have something.

Gas has changed an awful lot over the years and old information might not apply today.

He hasnt quite got the corners off his square wheels yet.
In time he will eventually improve his vaporizer until he eventually invents a carburetor.
He will discover that the fuel is vaporized in the carburetor venturi.
Then he may go on & invent fuel injection.
I guess at least he is staying out of trouble & getting his 3 minutes of fame on Utube.
