Vapor vs Atom, Coated vs Plain Intake Air Temps

[Dave Williams]

-> For this notion, of higher Fuel Pressure causes better atomization,
-> well again, how much effect can that really have if your firing at a
-> closed intake valve, like a batch fired gm TPI?.

 A typical Bendix-type injector only "atomizes" for a small part of its
cycle.  In time per cycle, maybe 1/3.  In flow per cycle, probably 1/2.
The rest of the time it's just pissing down the runner as the pintle
moves on and off the seat.


-> period of time.  It's been stated that the back side of the valve may
-> be as hot as 600dF
-> With it that hot, will coating the port with a ceramic barrier
-> treatment

 Heat transfer requires time.  You're moving several port-volumes worth
of air through the port ever few milliseconds.  There's not time to heat
much of the intake charge.

 This is where a little empirical experimentation might be worthwhile.
