I hope most poster in this forum now know my attitude regarding HHO and overunity by now. But just out of curiosity. Is it possible to use hydrogen on a fuel injected engine or do it have to be a carburettor engine

 

Google, as ever, knows all - http://avt.inel.gov/hydrogen.html

 

I think it would be, but I think you would have to adjust the air/fuel ratio. Guess what I'm saying is I would be interested in this also.

If solar cells became cheap I could see running a car off of hydrogen.

 

BMW has been experimenting with Hydrogen powered cars since the 70s. The entire ground fleet of the Munich (Munchen) airport runs off of it.

From what I understand it doesn't take a lot of modification, except for the bottle in the trunk. I don't feel H2 is really anymore scary than gasoline (which has more energy potential than either H2 or Propane).

Adding propane to diesel can be a hoot though.

 

Mythbusters took a carbureted vehicle completely unmodified and had a tank of hydrogen. They opened the tank and held the hose over the intake. The vehicle ran but backfired after a few cycles.

I would reccommend trying with a fuel injected vehicle. You would have to replace the injectors. most injectors are peizo based and the hydrogen, not being a liquid, wouldn't meter correctly. Once you had the combustion area size, you could calculate the amount of hydrogen needed per stroke and wha-la!

The hydrogen can also self ignite from hot gas left over from combustion, and spark plugs.
