A more appropriate reference for this discussion would be
http://en.wikipedia.org/wiki/Hydrogen_fuel_injection

The Brown's Gas injection process doesn't replace the normal fuel 
mixture as in the
water-fuelled car article, it merely adds free hydrogen to the fuel 
mixture.  This allows the
car to run a much leaner mixture under certain conditions (like idle or 
low load) with a
corresponding improvement in both fuel economy and emissions.  
Unfortunately for
the people who just fabricate their own unit, it takes extensive 
modifications to the
ECU's air/fuel mixture map to take full advantage of the system.
