Thread: hydrogen machine? :)

I don't understand why it is so hard to believe that replacing air with HHO would NOT lead to increased fuel economy. But there's no free lunch. The HHO system has to be maintained and checked regularly for example. But at todays gas prices seems like a decent trade to me.

As far as running an engine only off of HHO, yes it can and has been done. But there are issues here as well. First off you need to have enough HHO; that could be a large HHO generator for a V8. Second you will have to toally change your timing. Gasoline engines spark before the piston reaches TDC due to the time it takes for the combustion process to happen. With HHO only you spark and it explodes RIGHT NOW! Now your timing needs to be ATDC. Also you lose lubricating and cooling effect of the petrol based fuel which leads to hotter valve temps etc. Finally you will notice serious corrosion issues due to burning HHO and the water you get back from it. Life issues with HHO only vehicles is not well understood or demonstrated yet.
