Tornado fuel saver
It makes sense that by turbulating the air it would mix the fuel and air mixture alot better resulting in better combustion.

Fuel needs to mix well with the air coming into the engine intake manifold. Sometimes problems are caused by fuel condensing on the sides of an intake and forming puddles that drip un-mixed raw fuel into a cylinder (occasionally causing what we call a "Wet Plug") and in that form it will be blown out the exhaust, never to provide the power that might have been obtained from it.
The better fuel swirls AFTER IT IS INTRODUCED TO THE ENGINE, the better chance it has to mix, and that is a primary consideration in intake manifold design and testing. It is also at the forefront of every engineers mind when they think about valve flow, and upper chamber design. This thinking brought about the "Quench Head" upper chamber layout...
In the designs I have looked over for theoretically outrageously high milage carbuerettors, the common theme was to heat the fuel until it went from a liquid to a gas state, and them mix it with incoming air so that instead of being atomized droplets suspended in the airstream, the fuel would truly mix as a gas.
For whatever reason, we never saw this idea take hold and become prevalent. Some argued that it was because the petroleum companies would lose money - and bought the patents to stifle the idea.
We are currently standing on the edge of the alternative fuel era. What happens next is a coin flip - but I can't get over the idea, the feeling - that somebody has been lying somewhere.
And now we are about to make another major change....
