Hydrogen Fuel Injection. Does it work?

[Ciro Pabón]

I wonder if any of you have seen Hydrogen Fuel Injection actually working.

I read that instead of creating pure hydrogen in a chemical plant, and then distribute and store it, you can use the vehicle's alternator to produce hydrogen from distilled water through electrolysis, and then you push it into the injection chamber, apparently increasing the engine power.

Is this true? Does it work? All I`ve got is what I've googled. http://www.wired.com/news/autotech/0,2554,69529,00.html

That's new for me. But it looks interesting, as there is no need for hidrogen storage to be used as an additive.
I can imagine that mixing hidrogen and Diesel in the chamber must make for higher temperatures of combustion, probably faster expansion of the mix and better burning of particles. There could be, nevertheless, new polluants resulting of the temperature rise and possible long-term effects in engine reliability...

this is similar to a topic i created a few weeks back and yes in theory this should work whether it does is a different matter lol

Thanks, GreenPower Dude Reloaded. But HFI is a commercial idea and it means you do not use pure hydrogen: it would be a waste of energy/money, as pointed out by other forum members.

And, thanks, DaveKillens, but manufacturers of early versions of the HFI gadget claim a reduction in pollutants because of higher combustion chamber temperatures.

The idea of HFIis to use diesel oil or gasoline mixed with a little hydrogen. This hydrogen you get from electrolysis by attaching an alternator to your engine. The makers of HFI equipment say that the energy you get from burning diesel with hydrogen is greater than the energy invested in separating it from oxygen.

I do not know is this is some kind of perpetual moving machine, as burning hydrogen is, essentially, recomponing it with oxygen and producing water.

So the thing should not work unless this injected hydrogen is helping the diesel oil or gasoline to burn more efficiently. The article cites US californian measurements back in the sunny 70's. Did they smoke it green?

That is what intrigues me, as the URL I posted alleges U$700/month in fuel savings for a typical american commercial truck.

since it would require almost 3 Btu's of energy for every 1 Btu of energy produced by electrolysis of water for hydrogen fuel, it does not seem to be a very practical solution.

I always get a chuckle when I hear the greenies pushing electric cars as being "emissions free". Since 60% of the electricity in the US is produced by burning coal, an electric car is in effect a "coal-fueled" vehicle. Hardly "emissions free". Obviously, most environmentalists are too dim to figure this out.

As for the racing vehicle that produces the least amount of emissions, on a "well-to-wheel" basis, take a look at Audi's diesel LeMans car.

hi all,

m Raam , new to the forum.this is my first post here.

to begin with hydrogen as a fuel needs to overcome a few practical hurdles.

· Transportation and storage as it is a gas
· Compression and liquefaction result in loss of energy in the order of 25% to 40%
· Volumetric energy content is less at NTP
· Safety is a major concern as accidents can have severe repercussions

once we get aorund all these hurdles, we can think of hydrogen as a practical fuel...

cheers
