Blowing atomized fuel at a flat wall has very little penalty, to nice pretty
ports.
It sounds crazy but shearing fuel/air, and flat walls aint that bad.
  Depending on your purpose, might due just as well letting the fuel take
it's
own course.  Blowing the fuel against a deflector, may do exactly the
opposite
of what you'd expect.  Intake air is very dynamic.
