FUEL VAPORIZATION, DOUBLES MILEAGE

[pese]

Howdy Y'all,

Are you all familiar with the ultrasonic fountain?  I see them a lot in Asian stores, they are popular around Christmas time.  They are a decorative humidifier which use an ultrasonic element to vaporize water which forms a mist in the fountain.  The basic principle being  the water is exposed to ultrasonic sound which gives it enough energy to separate the water molecules and form a vapor.  In the fountain there is a self contained driver, some LEDs and ultrasonic transducer which a potted into a small stainless steel cylinder.  You just apply direct current to the device and it makes a light show and the water vapor mist.

Blessed Be Brothers...

Youse water vaporizers. that are made for room .
tje "ventilate" up to 1 liter @ hour in the room.

the are for 110 or 220v AC
but wor "internal wir 30 or 60 volt DC (different models)
that can produced very easy, (also tranfomatorless) from 12 volt
car supply (it must not used normal invers)

@All

As I further look at the Opel engine, I think this is what they are doing?

The electric fuel pump pressure is adjustable.  See on the dash, there is a rotary multi-position switch, or it mechanically adjusts the fuel pump pressure.  The fuel line then goes to the exhaust manifold where it gets heated.  It is then squeezed down into a refrigerator capillary tube where the heated pressurized fuel then expands into an expansion chamber.  As soon as the fuel inters the expansion chamber it vaporizes because it enters a vacuum condition from the engine intake manifold.  This capillary tube and expansion chamber is probably hacked from a AC unit of appropriate size?  Adjusting the fuel line pressure gives some degree of control of the mixture, along with the choke valve on the carb controlling the air supply.  The only thing the carb is used for is the butterfly valve to control the air supply.  Upon expansion, the vaporized fuel would give up heat and cool down, but then, you have the superheated air from the carb mixing it all together in the intake manifold.

If this is the principle of vaporization, then you could even convert a fuel injected engine.  Leave the FI stuff intact, but build another fuel system with its own pump and variable pressure regulator.  Run the fuel line coiled up inside the exhaust manifold heat riser designed for a hot air intake for a carburetor engine.  Then run it into a capillary tube/expansion chamber and then through a solenoid valve to engine vacuum of the plenum chamber of the FI system.  After the engine warms up, you flip the switch turning off the FI system and turning on the vapor system.  The FI air plenum chamber has its own butterfly valve to control air flow.  Lots of variables to tune to get it right, but maybe doable?

Maybe someone has a small lawn mower engine to try and see if the AC capillary/expansion tube hack works?
It is just an idea in my head.  I am not in a position to try it and see if it works.

I just posted this in another thread and thought you might find this interesting

I would agree, however your statement in itself gives us a clue as to the direction we should be heading. A lean AFR will "melt the pistons", as the expansion ratio(pressure) thus power developed is based on a rise in temperature in the cylinder how is it that a lean mixture can produce more heat?. In another thread I recalled how 20 years ago I was running a 1600cc VW engine on 80% methanol and had 8" blue flames coming out my 10" zoomy pipes(short exhaust pipes on each cylinder). I was running super lean and as you say super HOT, the issue was easily solved with proportional water injection and I retained all if not more power in the process of running a very lean methanol AFR. In truth most ICE's add extra fuel to "cool" the cylinder which makes no sense what so ever from the stand point of efficiency when you could easily add water to accomplish the same cooling.
What is not common knowledge is that the lean AFR follows a bell curve, that is as the AFR is leaned out the cylinder temperatures gets hotter and hotter then------starts to cool down as there is not enough fuel to produce the excess temperatures. This presents new problems as we are now in an area of combustion called "detonation" combustion. 10 years ago I built a few valveless pulsejet and pulse-detonation engines to explore this area further and I will tell you the transition from a conventional burn to detonation is beyond what we consider extreme. A good quality detonation in a conventional ICE would probably throw your cylinder heads through your roof in record time. In my pulse detonation engine I used schedule 160 pressure pipe that should tell you something of the dangers involved, however if you could produced produce peak temperatures at the top of the bell curve and introduce a "moderator" such as water vapor to control the burn I think this could work. Stan Meyers used exhaust gas recirculation as a moderator(atmospheric nitrogen) to control the combustion speed in his HHO injectors as can be seen in his patents.
I know this may seem a little off topic but if we are dealing with efficient "combustion" it helps to know the facts you are not going to read in the textbooks.

If you are going to vaporize fuel and lean out the AFR you should know there are "issues" to deal with.

Hi z.monkey
I would like to try your idea of ultrasonics on a ride on mower,however,I don't understand "plenum of the intake manifold pointed up at the base of the carburetor"in particular plenum, also the ultrasonic apparatus I would require.
I would be thankful for your advice on the above.
happy hunting

HELLO ALL,

IS ANYONE FAMILIAR WITH THESE PEOPLE? http://www.fuelvaporcar.com/index.html
THEY ARE GETTING 92 MPG IN THEIR 5 SEC 0-60 MPH CAR!

I JUST SENT THEM THIS:

CHEERS

Fw: New Generator Technology featured in Canadian Business Magazine

Dear FuelVapor,

My name is Thane Heins and I am the inventor of the Perepiteia Generator which has the proven capacity to recharge electric automobile batteries during 100% of the car's operation - not just in regenerative braking mode.

Our generator technology does not cause any deceleration under load (according to Lenz's Law) in fact our generator causes the prime mover to accelerate. Please see enclosed Ottawa University test data and demo video: http://www.youtube.com/watch?v=_vruf7s9PaA

Recently we have been featured in the Canadian Business Magazine and GQ Magazine is covering our technology in their October "Green Issue".

Neil Young has been in touch with us several times and he has expressed interest in using our generator technology in his X Prize LincVolt entry. We have presented our technology to MIT and NASA has also requested a demonstration.

We would like to offer our technology to your Canadian team as well.
I hope you find this interesting.

Congratulations and Best Wishes
Thane
