Atomization vs Vaporization

[Robert Harris]

Revist Ideal Gas Laws.

The absorbtion of heat in the intake tract and the cylinder prior to
combustion is not to affect the energy release of combustion, it is to both
reduce the work of induction and to increase the amount of the inducted
charge.

The heat of vaporization of fuel is large with respect to the inducted air
mass and thus can cause significant changes in the temperature and thus total
quantity of inlet charge.

Liquid fuel atomized to 10 microns or less ( you will see that number many
times ) burns not as a liquid - droplet by droplet - as essentially identical
to a pre-mixed gas.

A liquid "vaporized" has transitions to a gas state - with a significant size
change.  Water expands approx 1800 times going to steam - fuel significantly
less, but the resultant vapor molecule is orders of magnitude greater in size
than the liquid.

Atomized - preferably to 10 micron or less - fuel absorbs heat - thus cooling
the intake charge and increasing the fresh charge inductable - without
appreciatory changing the size of the fuel particle

Vaporization the fuel absorbs the heat, but since a state change is involved,
it greatly expands the space occupied by the fuel.  The benefits of cooling
are offset by the loss of space by vaporization.

Atomize - not vaporize.
