![]() " wrote It sounds reasonable that injecting H2 into your fuel stream can improve the combustion. Hmm, I dunno, I feel a little puzzled or suspicious of how he's achieving a net energy gain here. Can anyone debunk any obvious fallacies here? I'm not up to trying to read all of the web site, but the answer is to save your money. Water injection has been around in high HP engines, running at high, constant loads, for a long time. Will it become practical for your airplane or car? Car, no, because of the low HP, and non-constant loads. For airplanes? Yes, if all you want is a boost of extra HP, for a short amount of time. Some WWII fighter planes used them for an extra boost for take-off and for other times, such as dog fighting, where the extra HP meant life or death. Some air racers also use water injection. Why not all of the time? LOTS of water is needed to make much of a difference, and the weight for enough water to last for more than a few short bursts would be impractical to carry around. It also needed a lot of monitoring, which no doubt could be taken care of by modern micro chips. Lastly, if it was a viable option, wouldn't all major manufacturers be using it? You will have to ignore the oil company conspiracy theories, to answer that one. g -- Jim in NC |

Well, why do you equate H2 injection with water injection? From what I
see here, while water spray can act as an atomizer to increase surface area, the H2 is itself combustible. Isn't there a difference? |

Yeah, that's my story, and I'm sticking to it! g I'll try to read better, next time. I've only been at it for about 43 years! ;-) -- Jim in NC |

I knew a guy when I was in High School, good fellow, into his moped, car, etc. He rigged up a water injector on his moped to supercharge it, and got some serious power, until he blew out his engine. Got a heck of a battle scar on his leg, too.... but it was cool while it was going. Glad he wasn't hurt worse, he was a great guy. The huge increase in pressure is probably the reason. Building the engine to take that for longer periods would probably mean so much weight that it took the advantage of the extra power away.
