HHO as a car fuel calculations

[boostmr2]

Any of you math geeks out want to give this an attempt?

In the average automobile, lets say a 2-litre 4 cylinder motor, it is good to have a 14 to 1 air fuel ratio.

Air is only needed for the oxygen it contains, which is approximately 20%.

This means the oxygen to fuel ratio is more like 2.8 to 1, lets say 3 to 1 just for theory.

Would this be the same ratio we should expect for burning pure hydrogen as the fuel?  For each hydrogen molecule we need 3 oxygen for a clean burn?

Just a thought, I get lost when it comes to chemistry on a molecular level.  Hydrogen may require a completely different air/fuel ratio than petrol because of it's different properties.  But if someone could figure out what this is, then it's very possible to calculate exactly how many litres/minute HHO (or just H) need to be produced to keep a vehicle running at lets say a max of 8k rpm's consistently.  This seems to be the biggest problem right now.

The question comes up because most vehicle manufacturer's are leaning towards a fuel tank setup, not a fuel-cell setup for hydrogen vehicles.  I believe it is completely plausible to produce enough Hydrogen or HHO onboard the vehicle, and pressurize it, just like petrol is pressurized, and inject it into a cylinder for burn.  Since Hydrogen is much more volatile as well, it should cause the gases (air) to expand just as fast as petrol would but using less gas to produce the same power.  Plus its cleaner burning!  Any ideas?

Howdy,

That's a good question.  It may be up to experimentation.  I also think that the HHO generation may need to be throttled, meaning the HHO production needs to be variable and proportional to the position of the accelerator pedal, or the engine RPM.  One clue may be at NASA.  The Space Shuttle burns LOX and LH2 in the main engines.  If I am not mistaken the ration is 1:2.7.  The two tanks in the external tank are the clue.  The LH2 tank is 53,488 cubic feet and the LOX tank is 19,744 cubic feet.  The tanks are designed to be expended at the same time.  So hey, thanks NASA, that is your tax dollars doing something good for a change.  So we need a better control system for the Electrolyzer, and maybe a better Electrolyzer.  I know how to make a better control system.  Make it processor controlled.  Check out this other thread.

So far this idea has been more or less ignored in this forum.  By using a processor the control circuit can take external input such as throttle position, RPM, road speed, and environmental variables to get the Electrolyzer producing HHO in the correct ratio to the air intake.  This way we don't starve the engine or burn it up.  Modern gasoline engine management systems do this.  There are sensors all over the motor, and the engine management computer is continually adjusting the mixture to provide optimum performance.  You can really tell this too.  We take it for granted.

Here's to a cleaner, more powerful tomorrow...

Heyah,
burning H in O gives  water, reaction goes as follows:

2 H2+O2->2 H2O
so the ratio is 2:1 in volume.H and O are vary unstable as single atoms and gets really fast to the form of H2 and O2.So u need to base your calculations on O2 and H2.Both are gases and both occupy the same volume per Moll.You get out of the electolyser the exact ratio that you need for full burn.So air oxygen is the excess oxygen not needed in the case you burn only HHO from the elecrolyser.Some excess oxygen can ensure full burn of HHO.

If u want to calculate situation for any specific engine we just need the fuel type it is currently using and the kg of fuel per hour per kW burnt in this engine.Based on this u can easily calculate the amount of HHO needed to generate the same amount of work as other fuel.

i can do it for u tomorrow,

Uh, Creativity,
H2O2 is Hydrogen Peroxide...
That's rocket fuel...

where i wrote H2O2 ? it is just that hydrogen as well as oxygen forms a two atomic molecule when in gas state.So u have H2,O2 and by the way the same for nitrogen N2 .A lot of gases have this form in normal conditions.So when u have electrolysis you get H2 above one electrode and O2 above the other one,when u mix them u have H2,O2 gas mixture.H2O2 is liquid and it is a molecule of 4 atoms.
