Greg:
This is valid. The superheated steam makes a nice cleaning
agent, and water injection is also a way to reduce knocking and increase
power. It recovers a great deal of otherwise wasted thermal energy from
the combustion process. The problem is that superheated steam is very
corrosive, so long term durability is problematic. But as a one shot
cleaning treatment, it works and is cheap.
If you are struggling with run on, this MAY help but it is more
likely that the problem lies elsewhere. Incorrect mixture, idle speed
and ignition timing are more likely to be the culprits. If your car is
equipped with an anti-run on circuit, you should make sure it is working
properly too. Run on is more of a problem as the compression ratio is
raised, so modified engines have more of a problem than stock ones.
Carbon residue can glow and act as an ignition source, so this
can be a problem, but a well tuned car will *generally* not have this
problem.

I was re-reading an article printed in a club newsletter from the
distant
past about an old time mechanic who recommended water injection to
eliminate this problem.

Does anyone have any thoughts to the validity of his actions?
