Asking question again….Does HHO gas mixture really reduce some (not replace) fuel consumption?
Wikipedia Oxyhydrogen is a mixture of hydrogen and oxygen gases, typically in a 2:1 atomic ratio, the same proportion as water.[1] This gaseous mixture is widely used for torches for the processing of refractory materials.[citation needed] [edit] Properties Oxyhydrogen will combust when brought to its autoignition temperature. For a stoichiometric mixture at normal atmospheric pressure, […]
