Ringway / Eurovia taken in by HHO scam?

According to an undated “news” article from 2010 on Ringway’s own website they are trialing a “revolutionary Hydrogen Fuel Injector” which they think has “the potential to reduce fuel costs across the entire group’s fleet by up to 20% as well as a significant reduction on carbon emissions”.

Sound familiar? Yep, it is just another run-your-car-on-water-scam clone.

Working in partnership with designer Simon Haswell, the Hydrogen Fuel Injector (HFI) uses the excess power of the truck’s alternator to electrolyse distilled water and inject the resulting hydrogen and oxygen into the diesel engine’s fuel injection system, prior to turbo charging. The gasses give a significant boost to the fuel burn within the cylinders, considerably reducing fuel consumption.

Of course (as everyone must know by now, or maybe not everyone in the world reads my blog?) there is no such thing as excess energy, energy comes from somewhere, and in this case it is coming from the engine and therefore the fuel.

These types of systems have been shown to not give any significant boost to the combustion and when the extra fuel being burned to supply the “excess energy” is taken into account they are always shown to , in fact, have a detrimental effect on fuel consumption.

This is never a surprise to anyone who knows anything about physics or internal combustion engines, but it is usually a surprise to the “inventor” who usually starts to scream that scientists don’t know what they are talking about… it gets very tedious.

These systems have been about for well over a decade, thousands of people have “invented” them, and when tested under controlled conditions they are shown to not work.

It seems that Simon has even tried to patent his “invention”.

Has  Simon Haswell (not an engineer or scientist, but a photographer from Tunbridge Wells) managed to find a way of making this work when thousands have failed before him? It is possible I suppose. But is it likely? No, not really.

    Have designed an excellant hho generator using open source which is delivering more than 1 lpm @less than 10A to be used in my opel corsa 1.4 engine. Test results are erratic. I do not want to use any other electronics and to disturb the existing electronics. Any ideas?

  2. Jon:

    Hi Bob,
    Your test results are probably erratic because there is a lot of uncertainty, error, in your experiments; there are far more variables, unknown factors, affecting your experiment.
    Have you simply tried to leave the HHO generator switched off and see how erratic your results are then? I did this in my old petrol 206 and got massive variations in MPG, nothing consistent at all. Don’t mess with the electronics, it is illegal and will damage your engine. You can save a considerable amount of fuel by learning green driving techniques ( http://en.wikipedia.org/wiki/Fuel_economy-maximizing_behaviors and http://en.wikipedia.org/wiki/Hypermilers ) and those “ultra” fuels you can buy have been shown in the lab to improve things by as much as 10%.

    Hi Bob,

    Modifying the electronics is not illegal currently (unless any of these modifications are not verified and disclosed to your insurance company), but may indeed damage your engine, however, it will be the cause of the issues.
    The computer knows there is more oxygen, and will increase the fuelling which is a result of the increased oxygen content added by the HHO unit.

    You will need to only add hydrogen if you are planning not to modify the computer.

    Hello Mr. “Z5″,
    Firstly, comments with links to HHO sites are spam and will be edited/deleted as such. Secondly, what a load of horse shit! Tampering with your vehicles pollution management system is illegal just about everywhere and adding “hydrogen” makes no difference to this; cite me one single bit of credible science that backs this nonsense up. You making this stuff up, arn’t you!?
