I know nothing about the Saab. There are few of them in this country so
I can't comment on them. However that system (allowing more fuel in)
would, l would think, increase engine power and also increase fuel
consumption, which was not what the discussion ws about. As for adding
alcohol to fuel that is already done in this country. There has been the
great ethanol debate raging for several years.
My comments were that the only report I have seen on such a system was one
which came to the conclusion that, after testing, there was no benefit in
such a system as that which adds water to the fuel.I don't back away from
that as it is fact. The test was reported when a device of this nature
was being advertised in this country.The aim of this devce was to improve
fuel economy.
If this system was sucessful in one make of car why has it not been put
into general use. Any device that saves fuel shoud be popular. Seems
strange to me. What other makes of cars use such a system?
Cheers,
Bob VK6BE.

water cools the air and increases the density of the air and so allows
more fuel in. This allows a higher compression ratio with lower octane
fuel. Normally you get predetonation but this system supressed that. On
the SAAB a tank held the water and should you run out of water, the
ignition control system retarded the timing to stop the engine pinking
itself to death.
