That does not logically follow.  Air and water vapor
do not have identical characteristics in terms of
physical behavior.

Displacing it to where?  And how?  It's the same
number of water molecules.  The molecules don't get
any bigger, they just spread out and hold heat energy.

ISTR some very different reasoning behind keeping the
water from absorbing too much heat before being sealed
in the combustion chamber, but perhaps I misunderstand.
