atomization enhancement

[Gary Derian]

A "puddle" of fuel in this context can mean a cloud of droplets in the port.
The shock wave that hits this breaks up the drops into smaller ones.  Sure
it gets diluted, etc. but its the best we have for now and it does work
pretty well.  The only way to inject atomized fuel in a short period of time
is with a mechanical injection pump except maybe the stuff used in single
rail diesels.  Does anyone know what the single rail diesels use for
pressure and injectors?

One question I have is When does a SEFI system fire the injectors, during
the intake stroke or some other time?
