Installation of a Hydrogen Generator for my 1971 Chevelle
I decided to try one of the Hydrogen assist kits that are available now to try to get better fuel economy from this car. What the system essentially does is take an electrolyte, which is basically distilled water and baking sode or KOH, and by electrolysis produce hydrogen and oxygen, which can be fed into the intake. This hydrogen not only act a fuel, but allows the gasoline to burn much more efficiently. Do a google search for HHO and find plenty to read.
In the photo's below the 2 stainless tubes are the generators, they contain the electrolyte and the stainless steel plates. The hydrogen comes out of those and feeds into the blue bubbler. This acts a flash back arrestor and a filtering device for the hydrogen. I have the output of the bubbler going right into the base of the carburetor. I have a 40 amp fuse to protect the system and a ignition relay to turn it off when the car is shut off since it is connected directly to the battery. I also have a switch installed under the dash to turn it off if I need to.
7/9/2008- Installation of HHO kit. I put a mixture of a gallon of distilled water to 2 TBSP of baking soda.
7/17 - Drove it 145 miles and used 6.85 gallons of gas which is 21mpg. I usually get 18mpg so this is a good start. System drew about 25 amps, didn't notice too much of a difference in performance, but I did notice that it doesn't ping anymore and the engine seems to run cooler.
7/19 - Flushed the system out completely. I was surprised at all the gunk that had been built up in such a short time. Replaced it with a solution of 1 gallon of distilled water to 1/2 tsp of KOH (potassium hydroxide). Supposed to run cleaner and produce more HHO.
7/24 - Drove it 147 miles and used 6.36 gallons, 23.2 mpg. That is a huge increase over my baseline 18mpg. Going to do a volume test this weekend, I'm pulling about 22 amps and the solution still looks pretty clear. Going to take some more pictures this weekend also.
