Here's one I just read:
http://www.canada.com/montreal/montr...ry.html?id=cfe... Some fellow is claiming he has a small device that will boost combustion efficiency and save drivers lots of money, while reducing emissions. Obviously, plenty of claims have been made before, so I'm asking -- does this sound on the level? It sounds reasonable that injecting H2 into your fuel stream can improve the combustion. I assume that combusting the H2 in your cylinders along with the regular fuel will boost temperature to give a cleaner burn. Would the higher temperature harm your engine life at all? Since this device supposedly only holds a limited supply of distilled H2O, KOH, etc which get periodically replaced, can I assume that it's catalytically cracking some hydrogen from the hydrocarbon fuel stream itself, so that hydrogen can improve the combustion of the remaining fuel at the cylinder? Is this somehow akin to a sort of turbocharger, but which uses hydrogen instead of pressurized oxygen? Can it work for other things like aircraft engines, in order to boost their operating ceiling? 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? |

combustion efficiency and save drivers lots of money, while reducing emissions. Obviously, plenty of claims have been made before, so I'm asking -- does this sound on the level? Water injection has been around for a long time, both for internal combustion and aircraft jet engines, it does improve efficiency, reduce temperatures and reduce some emissions. It depends what is being claimed for the actual device. Regards Jeff |

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 |

I read the web page ad, and every single paragragh had at least one outright falsehood. Some paragraphs had several. Most also had classical marketing misdirection and dissimulation. The bottom line? YOU CAN'T GET SOMETHING FOR NOTHING. Everything this guys says violates conservation of energy and both the First and Second Laws of Thermodynamics. It's a simple bilko scheme. -- Harry Andreas Engineering raconteur |

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 |
