hho [hydrogen] generators???

[softailer]

Has anyone ever had any experience using an hho generator/cell on their trucks before. How did this work out for you? Considering building one for my 5. 9. Would appreciate any input from those that have done this.

The universe has this rule -- conservation of energy -- so the energy you gain from burning the hydrogen can never exceed the energy it take to make the hydrogen in the first place.

Not working out like these folks hoped it would. Kind of sounds like some kind of Green California thing OH IT IS :-laf

Hasn't worked on a couple of gassers around here either.

Hydrogen as a fuel source by itself is as clean as the energy used to get the hydrogen.
The real problem is the "kits" to make the hydrogen onboard while driving. Those are the biggest lie.

in test's we did for a customer, there was not as much loss in mpg with the hoh generator as we calculated on paper. think about it for a minute. when the hydrogen combined with the oxygen it gave off heat. to separate the hydrogen from the oxygen it takes the same amount of energy, with the alternator-battery efficiency at about 70% and engine efficiency to run the alternator is about 35% you have to loose at least 50% for the minuscule amount of hydrogen produced. next look up the cubic feet per minute the engine needs at cruising speed and figure the output of the generator and you can see it is like urinating in a Olympic size pool to raise the level. also power derived from fuel is near related to the weight of the fuel, not the volume. you need one pound hydrogen to get work of one pound diesel.

I spent some time reading up on the HHO generators a couple of years ago. CKelley1's calculations on efficiency are right, so what could explain some people being able to show better mileage? My theory was that some vehicles were burning the fuel incompletely and that by adding in a little bit of hydrogen they were getting a more complete burn, thereby getting better mileage. The overall effect should be close to a small propane injection system. However, I don't think that the HHO systems will help at all in an HPCR 5. 9, they already burn very efficiently.

The laws of thermodynamics trump the salesmanship of perpetual motion machines.

For the same reason that people loose weight on all kinds of different diets. If you pay attention of how you drive (eat) you will get better mileage (loose weight). I can get about 2 mpg better just by paying attention of how I drive.
The second issue with MPG is you HAVE to have a min 3 tank average to tell anything. Some will compare there WORST tank with a current BEST tank and claim the improvement is because of X.

I think what WOULD help increase milage and power would be if they went back to #2 diesel fuel that was as heavy as it used to be. It would have more BTUs and give more energy. The stuff we get now is more like kerosene. I remember the fuel smelled like oil and had an oily consistency. If you spilled some down the side while filling your tank it would be there three days later. Now it evaporates almost like gasoline does.

I wish they sold diesel fuel by the BTU rather than the gallon.

 

[Joseph Donnelly]

Winter fuel costs about 5% and the new ultra low sulfur costs another 5% or so.

Who knows a chemist that works in a refinery? I would like to calculate how much #4 or #6 fuel oil would need to be mixed with the current pump diesel fuel to achieve the old grade of #2.
