Boosting MPG with hydrogen (HHO) cell

[PuntoHowTo]

in the case of LPG use in diesel engines (which has been about for years now) the gas is used to replace some of the diesel fuel that would be burnt instead its also fed it at a far greater rate and carried in a pressurised cylinder

with water electrolysis you have to carry water = weight, you have to carry equipment to split the water, then you have to take power away from the engine in order to power the HHO generator.
electrolysis is an extremely inefficient way to create hydrogen and the claims above suggest 200ppm of hydrogen would be added to the mix 1 hour driving would need around a litre and an half of water which would need to be carried.

if you could show some improvement in combustion efficiency even with such a tiny amount of gas the benefits would be far outweighed by the energy cost of producing the gas and carrying the extra weight

as people keep pointing out time and time again, if it were worth while the manufactures would be all over it, where as pretty much all hydrogen research has moved away from internal combustion over to hydrogen fuel cell technology because its far more efficient, and even then its still not efficient enough to turn into a viable replacement for fossil fuel internal combustion at the moment.

The point of all this rambling means that basically, the far heavier Punto has more power yet has very similar efficiency to the underpowered Panda therefore why give everyone a Punto 55 when you can have more power but with the same economy?

.... I can't say that any of this information is very accurate but its just some of my thoughts...

I replaced my mk1 55s with a a mk1 85 elx...and my fuel economy went from 38mpg in the 55 to 43-48mpg in what should have been the heavier less efficient car for the simple reason you weren't constantly pressing your foot to the floor to keep up with traffic. With the added bonus it felt like a real car because you could join fast moving roads and overtake with authority.
