I have been to a garage today to have my gas tank pipe work re-done. While i was there, a guy came in for some chemical for his Hydrogen tank. This system is fitted to a Peugot 405 diesel car with 160,000 miles on it. The guy travels all over the country with his work and says, “It’s been well worth the £ 600.00 investment to have it fitted. He says, he used to do a round trip to London and this would need 1 full fuel tank. With the system fitted he now does the same trip and still has a1/4 of a tank of diesel left. The claim is that the system increases power by between 19-24%.


Has anyone else heard about this and if yes have you spoken to anyone who’s had it done????????????

Hi Patrick,

There is a 100 post thread Link Removed about the Hydrogen generator, a good read if you have a spare half hour.:Smile:

Think this might be a similar thread thats been on RVOC with dispute as to whether it actually works

No one has ever demonstrated that this actually works, and here is why

If you convert 1 US gallon of water to hydrogen by electrolysis it will yield 420.6 g of hydrogen (H2 gas). If the electrolysis is 100% efficient it will take 16.821 kWh of electricity to crack 1 gallon of water. That 420 g of H2 only has an energy density of 14 kWh (33.3 kWh/kg * .4206). That's 16% more energy to crack the water than you get out of it. At 70 percent efficiency that means it would take about 24 kWh of input energy to produce hydrogen with 14 kWh of energy output.

... but have a read here and on the link Jim gave on RVOC

and there are plenty of mugs out there who will make it a profitable business ...

hi patrick.
have a look at this thread from the sister site RVOC.

Mike went to the trouble and expense of having this unit fitted as a personal experiment only to find he'd been sold a pup.

I was thinking of having this done a while back, but after googling it , most thoughts were as previously stated-ie. it doesn't work!, so save yourself a few hundred quid and don't bother.
Cheers, Dave:thumb:

hydrogen fuel for diesels

dont know about hydrogen, but lpg with diesel works have a look at tinley tech lpg conversions. no link with company

nah!!! missed jims link and spent too long looking for the thread over there then posting it here.:Blush:

Thank's to all of you for saving me from wasteing all that Vodka money

How frustrating is that!

thank's for taking the time John!

Excellent link Jim, only one thing to add, according to "boff" on facts, 70% efficiency is only obtainable in commercial installations, using the scam merchants methods, 50% or less is the best you will get, the rest is converted into heat.

I am as sceptical as most if not more so but I remember a mega thread somewhere a good while ago and it left a bit of doubt in my mind.

I do remember someone in the UK with a Pug 205 had done a DIY job and made incredible claims. A pretty aggressive woman from memory. Someone from the fuel industry was involved. Just about everyone said "if it works the manufacturers would fit it as standard". It was a very passionate thread.

Why the doubt ?

Well the calculation of burning hydrogen certainly makes a nonsense of it BUT someone used the word CATALYST. There was a chance that a small volume of hydrogen injected into the normal air/fuel mix would improve the combustion. No-one disproved this as far as I remember.

I'm in agreement, hydrogen would improve combustion.
The issue is the amount of energy required to produce the H2 .. as pointed out, even the best H2 generators are only 70% efficient.

The makers of these H2 devices claim the energy used in producing H2 is surplus from the vehicle alternator .. and costs nothing .. now that is a load of bull .. no such thing as free energy ..


I recall some 30 years ago, a neighbour of mine who was a science teacher, made a water device that drip fed water into the inlet manifold and claimed it improved MPG ..
Now whether it did or not I've no idea, but it sounds more feasible than an H2 generator running on 'surplus' energy .

Rings a bell -- they do/did inject water into jet engines intakes to improve performance, not sure why now.

But of course Google always knows....

ah yea indeed,

steam is also injected into the fuel oil in oil fired boilers.. not many about today due to the cost of fuel.. The one I was involved with at Inverkip, back in the early eighties, is now mothballed..

I've always thought my cars ran better on cold wet nights, denser moist air, so there may be some validity in it ..

So, what if we generated steam from the engine cooling system and injected it into the combustion chamber along with the diesel .. ?

:roflmto: I've mentioned this many times in the past on lot's of different Forums. They used to push water injection the same as they are pushing Hydrogen generators for motor injection and other items that are supposed to make the fuel burn better and last longer and more efficient and more and more and more.
In ALL my different investigations over many fruitless years I have YET to come up with one that consistently does as it says on the box. Still searching...............

BTW. I thought back in the late 50's I had come up with the solution to perpetual motion. Obviously I hadn't. I forgot to calculate the losses in the production of electricity from an Alternator being run from a Generator that was started up via a battery or pedal cycle and then used to feed back electricity to the alternator that then ran the generator that then ........................ :Blush:
