Water Injection for power?

[Dave Williams]

-> article that may be of interest.  The author suggested that, instead
-> of the usual fan/radiator/et al, the cylinders be cooled by injecting
-> water (diesel style) during the latter part of the power stroke.  The
-> H2O would flash into steam, thereby changing the heat (normally
-> exhasted) into mechanical power.

 Direct-to-cylinder cooling has been used on some large Diesels.  Worked
okay, as far as I know.

 "Six stroke" engines have also been built, with water injected after
the exhaust stroke.  The water flashes to steam, provides a little extra
kick, and cools the cylinder.

 Either scheme requires a large supply of water, approximately as much
by volume as the fuel supply, making such things awkward for motor
vehicles, though it's no big deal in stationary installations.
