In this forum I read that for a gasoline engine it is needed 0.5 L of HHO per L of engine displacement and 1 L of HHO per L of engine displacement on diesels, but how did you come up with this numbers?..I mean if someone did some test by himself or it is based on what many people have seen on their own tests?
I ask this because I believe that there is a ratio between gasoline and HHO to get the maximum benefits, just as there is a ratio between gas and air to get a full combustion.
I'm going to do some test, but I wanted to know first what do you think.
