Has anybody played around with or know anything about HHO, BROWN GAS, HYDROGEN FUEL? All of these are names for Hydrogen which can be made from water as water is 2 parts hydrogen and 1 part oxygen. It is what drives the space ship. There is a web site www.water4gas.com that states you can use it on diesel engines to boost mileage. They also talk about a MAP sensor enhansor that changes the signal from the MAP sensor to the computer so the computer will lean out the mixture to compensate for the hydrogen. It is very interesting to me but at the same time I am alittle scepticle. Does anybody know about this with diesel engines or even gas engines for that matter.
