This maybe a case of the person that did the website knows how/why this works & assumes that everyone else how/why it would. Also, the "meat" maybe further into the website than many people will go.
IMO, I'd have a section on that website on how/why/when this works. Here is some of what I'd including:
Hydrogen =
1. Detonation robs mpg & octane suppresses detonation.
3. To lean of a condition causes detonation.
3. Hydrogen is 130+ octane.
4. Within OEM specs ones engine maybe running to lean(well known fact in engine performace circle) & the addition of a little H2 may end that detonation & increase mpg.
5. Some links to the above info.
Water injection =
1. Detonation robs mpg & a rich condition suppresses detonation(mpg bad).
2. Water injection suppresses detonation & explain why it does. Many OEMs shipped their kerosene engines with water injection systems years ago for this reason.
3. A quick overview of WWII fighter planes. US had alot of av gas & used a rich condition causeing the use of more fuel per hour. Japan & German didn't have much av gas & used water injection to suppress detonation, therefore using less fuel per hour. Although there are some apples & orange in the mix, compare the gallons per hour of a Zero to a Wildcat.
4. Within OEM specs ones engine maybe running to lean(well known fact
in engine performace circle) & the addition of a little water may end
that detonation & increase mpg.
5. Links to the above info. There have been thousand of pages written on water injection.
I assume that the black box is decreasing the number of milliseconds the the fuel injectors are injecting fuel. If so, the follow is true.
1. A shorter injection time leans out the mixture.
2. Within OEM specs ones engine maybe running to rich(well known fact
in engine performace circle). The blackbox would lean the mixture & increase mpg.
3. If installing the blackbox cause a lean condition anywhere in the working envolope of the engine than the hydrogen/water injection is needed.
Tired of typing now. But there is every reason to believe that from an engineering aspect that this tech & info can/will increase mpg. It can also be worked with by most people who have the desire.
I have no $ interest in this. I have no solid idea as to how much oil would be saved per day in the US if everyone did this method. But if it was a 5% increase in mpg that would nearly 600,000 barrels a day in US fuel saving. The Japanese & Germans got greater than 5% savings, so 5% maybe possible.
Myself, if I wanted to play with a spark ign engine now, I'd scrap the OEM ECU. Put on 2 Megasqurits. One for fuel & one for water injection(to each cylinder).
