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.
