Beer_Guy Claims 100mpg+ Carburetor, page 2

Water injection into a four stroke gasoline engine is not new but has been around for decades. I first bought one out of a J C Whitneys catalogue years ago. When It came in I looked at it and said..I can do this myself.

IT actually works in my cauberated 6 cylinder GM Biscayne. It takes some time to get it adjusted correctly. IT mostly is noticable on long trips but then again your best gas milage is on the open road ..not on city stop and go traveling. I can tell this clearly in my moped...city driving here sucks up alot of stop and go gas milage.

THe injection works by vacuum pulling the water vapor or a very small stream into the intake manifold where it is vaporized. IF you adjust to much water the motor will begin to stall. All you have to do is make or fabricate sufficient connections to hook up the system. Water is stored in a plastic bottle of sufficient size and mounted in the engine compartment. This is not a problem in my olde Chevy but space may be more difficult to find on todays cars. THe valves doing the water adjustment are fine fish aquarium valves..fine thread. You can even install a bypass valve to dump water back to the bottle for finer adjustment if you are so inclined.
IN the winter time I just added some rubbing alcohol to the water in the bottle.

This does work but it is not a quanutm leap in milage like some are claiming in these miracle cauberators or system modifications. This is simply a adaptation of the principle you observe when driving on very damp days where it seems like you have a few more horsepower due to the density of the ambient air.
As I recall once I got this adjusted correctly it made a difference of about one eighth to a quarter of a tank over a long high speed trip. Not as noticable in around town stop and go driving.

Years ago you could get a series of books in the psuedo underground book market...

Browns Book of Caubarators.

Supressed inventions and how they work

Browns Alcohol motor cookbook.

I have all three books bought years ago. I dont even know if they are even available anymore.

I have thought for years about fabricating a heat exchanger to pre heat gasoline using water as the heating medium...water from the engine water jacket using a coil inside for the gasoline to pass through. Now that I have purchased a wire fed welder this should be easier than the olde stick welding. You just have to use parts which are stout enough and able to survive anti freeze corrosion. Also you have to be aware of the space limitations on todays cars and trucks. Not much room in many of them.

IN Brown's book of caubarators this heating is done with exhaust gases heating the gasoline through heat exchangers in some designs.

I am not sure however that this would work as well on fuel injection verses say..caubuerated engines. My experience has been on caubuerated engines.

However to be fair on the subject ..I also believe that the electronic ignition spark has great potential in helping with this endevour. This is a great invention. Also very versatile to those versed in its workings.
My olde Chevy still has points and condensor and yet it works in this car.

Also the person concerned about heating gasoline...remember ..the flash point of gasoline is much higher that paper. Some 600 to 800 degrees as i recall verses 451 degrees for paper and wood. What you are concerned mostly about is spark in the wrong place. Also a type of relief system for over pressurization would be necessary. If you look at many cauberator designs there is a fine spring relief valve built into them. A bypass dump system might be in order too.

Take a close look at your electric fuel pumps...they dumb the excess pressure back into a line going back into the fuel tank. Nothing complicated about this.

Some intresting posts here,
