HHO vehical / law of conservation

[Creativity]

When u burn gaseous H2 in O2 u get gaseous H2O and heat.When burning fossils u release CO,CO2,H2O.Of course in both reactions in reality in ICE u get also some other gases like NOx.so fossil fuels have H2O already there when burning(just wanted to say that water vapour is not a totally new chemical in reaction).

2 volume of H2 and 1 volume of O2 produces 2 volumes of H2O(all of it accounted as gaseous because temp is above critical for water).So when seeing this partial pressures,after the burning pressure would drop(before reaction 2+1--->after reaction 2).It would drop if heat produced would be taken away(keeping the reaction with constant temperature).That heat is not removed it allows to expand gaseous H2O to take more volume than H2 and O2 had before the reaction started.

Burning of fossils ends up with more gases that u have in the beginning(so not like burning of hydrogen)+heat.So by burning up fossils in constant heat with removing excess heat u will end up with high pressure(not like burning H2 where u end up under atmospheric pressure).This extra pressure is already extra work that this gases can perform.If u account for heat produced that is normally available to further pressurise gases,the question is:

when substituting fossils with hydrogen,do i end up with higher total pressure than when using fossils only?(pressure is what is a usefull power in ICE)
To answer u would have to show that burning of hydrogen and expanding of H2O produced by it is of higher end pressure than
burning of fossils.
If u would say that hydrogen is more favourable,then u go against the fact that in practice ICE has less power on hydrogen fuel only.

that's why i stay with my opinion that fast burning rate of H2 ,O2 mixture is the main reason of added efficiency(higher peak pressure,more  complete burn of fossil fuel and less time to loose heat to the engine components).

PS:In both cases of burning there is also air that is heated to expand to do some work.

Nice explanation. Thanks!
What comes to mind is water vapor injection. How does that figure into the equation?

[Creativity]

there are two ways that i know of.
1)One i know for a long time already and is so old as the racing cars itself  .Water injection was used to allow higher compression ratio's and/or to chill down the piston crowns/valves.Depending on the car (turbo or NA) water was used to prevent knocking under max load of the engine or to chill it down under high boost.In both cases water was not supposed to be a vapour until it was in the combustion chamber.How it worked?
On NA engine maximum compression ratio is set so it won't start to detonate under fully open throttle at full load.If we could get CR(compresion ratio) higher and avoid knocking,both extra power and extra fuel efficiency would follow.In racing cars power was the goal .Water droplets start to evaporate and it takes heat to do that.In that way evaporating water was chilling down the interia of the engine before the ignition.In tuning terms it meant that u can go with higher CR if u inject some water.That was a good trade,because higher pressure of gasses (following higher CR) positively outweighted loses of energy to evaporate water.It is worth to note that water wasn't injected all the time but only in the moments that detonation could occur(full load of the engine).
As i see it Injecting of water(not vapour) can have some positive effect on today's cars with detonation sensors.In this cars CPU is adjusting ignition advance,when it hears detonation start it adjusts the ignition so it will avoid full detonation.Of course timing goes in the direction of worse power and engine is less efficient in fuel.If u could inject water in the moment when detonation occurs,CPU would not change ignition settings and so a bit of power and efficiency could stay where it was.
With turbocharged cars there is more of a problem with the high thermal load on the interia of the engine.Water by evaporating cools down the hot spots,that can be a sources of knocking.Other way is to inject water on the intercooler(not into!),in this way efficiency of the intercooler gets higher and higher boost is tolerated.Those are just simple words on how it works.

In this light,adding of water into the system makes no sense if no changes to engine settings follows(higher CR,changes in ignition curves,changes in valves timing,higher boost...).

In this case water works as an enabler for changes in the engine.So extra power or efficiency is not because of the water(methanol or more fuel can replace water in its job-but both are more expensive than water) but because of the changes that are now allowed to the engine.This subtle difference should be seen.

2)something that i got to hear recently but i can not verify it ,is that water is being split into Hydrogen and Oxygen.well i had no further explanation how would it work so i let myself to come with a possible theory to back it up.I would have to check at what pressures and temperatures would it be possible to achieve it(maybe some additive to the water would be needed to work as a catalyst  ).Further if that splitting occurs close to the peak pressure of combustion it would have a very minor role in speeding up the process that is almost at its highest speed at that time . To take maximum advantage of any speed up we would have to adjust engine.Here i would dare to say that water vapour would be somehow better than water droplets used in the racing cars.The bigger the droplet the more time it takes to evaporate,in race car u don't want it to evaporate before ignition.Here u want water to be ready for splitting as fast as possible,evaporating it first can seed it up i guess.
Evaporated water already received energy form outside and won't rob us from the combustion heat(what follows pressure won't drop because of the energy put into the water to evaporate).
In this case water takes an active role in combustion as opposed to the first case i spoke about.Again any change to the combustion properties should be reflected in adjusting of the engine settings( if we want to be sure that we get all of what can be taken).


Now i can imagine that both effects take an active role in the game of a combustion  .

Hmmmm....good schtuff you got there....


Well, if Hydroxy burns MUCH hotter than gasoline, wouldn't the incorporation of a little water vapor aid in keeping combustion temperatures under control?

Some people claim you can wrap your O2 sensor(s) with aluminum foil to remove the added heat.

And the electrolyte you refer to can be 100% Lye, Potassium Hydroxide, or least preferred Baking Soda.

Now, about controlling the engine. That is an entirely different set of problems.
Trying to overcome the computer's adaptive memory is extremely difficult on most cars.
