Best look at the rules about applying for patents first UJ, it's a nightmare Laughing

I hear and understand what you're saying UJ, but don't quite understand why? I think we might be approaching the "creation" of power from different ends. Very Happy

Oh well UJ, time I finished playing the 'devil's advocate' I expected more people to join in. I've certainly learned a few things. I admit to being sceptical about these units but I'm willing to give them a try. Cool

I'm no physicist but I think there are some contributing to Wiki. Take a look at the Lower Heating Value of Hydrogen relative to the electrical input required for the electrolysis:

Also take a look at:

Pigtin, you could always try a perchufter valve....

[quote]Particularly noticeable on the merc, when I start it, it ticks over at 800 rpm. After about 20 seconds when the unit kicks in the engine revs drop to 600 and the engine goes a lot quieter.

PeppiB,

If there is an improvment in the combustion the RPMs should have increased. I worked for twenty odd years as a tune-up mechanic and as you adjusted the engine be it carburation or ignition as the optimum value was reached the engine would have increased in RPMs and ran smoother. Some questions: How is this gas supply modulated to cope with increase in revs or load. Another source of hydrogen is the battery as it charges. Why is this not being 'harvested' too. Can you tell me how far apart the plates are in the gas generator so that we could perhaps measure the current required.

The electrodes are 3cm apart because that fits in with the container size I use. The gas is an aid to the normal petrol and is not modulated. The revs certainly drop when the unit clicks in. Even at 600 rpm, in drive, the car attains over 30 mph and sometimes i have to run with slight braking to keep within the speed limit. Before installation of the unit, the tickover speed of 800 rpm would only move the car at about 15 mph.

Not a clue of the technicalities of why that should be, it is just the way it is.

It is still saving me money at the pumps!

I must say the reports of operation are very attractive (if you ignore the rather high fire risk in the event of frontal impact) but I've yet to see any scientific description of how the system is supposed to work.

If there isn't a scientific explanation then we are discussing myths and legends and I've managed to survive all my life without them and the mythical prospect of the firey furnace causes me no loss of sleep (although it might if I'd fitted a jam jar full of hydrogen and oxygen to the front of my car). Shocked

Art, I stand corrected. This road I was on yesterday must have been more of an incline than I thought. On a definite level today, on tick over, the car was doing 10 mph.

How's the project going peppiB? I've assembled all the bits and am just waiting to clear enough space on my workshop. I'll try it on my 32 Austin 10/4 as any increase in perfomance would be easily detected.
Not quite sure of the grade of SS I have but will soon find out if it's wrong.

Don.

Just a quick update on this one. The merc has now covered 1500 miles, mainly in the city and around the pennines, with only 1 long journey to Birmingham and is averaging 38.7 mpg which isn't bad for a 5 litre V8. I flushed the unit out yesterday as some sediment had formed in the bottom and I also swapped the polarity of the electrodes to even out any possible 'wear'. Haven't had the Minor out since I fitted one on there and did a lakes trip averaging 55 mpg. I put one on the landcrab the other day and she was purring along when I took her for her MOT this week. She failed Shocked

Drove 20 miles to the testing station I use (along a motorway) pulled into test bay and a brake pipe burst!! Temporary repair and moved her to a friends industrial unit 3 miles away from that garage and all the brake pipes will be replaced this week, so she should be through her MOT by weekend and see how she drives home.

Don - missed your post for some reason. I just used heavy duty stainless mesh as I am not strong enough to roll stainless sheet. The USA website recommend marine grade (can't remember the number, possibly it was 7 or 16) but I am happy with the results I am getting. if at any time I can manage to make the electrodes from sheet it is an easy job to swap them in the unit.
