Sorry about that. Between this 1963 East German surplus computer and AOL,
some transmissions must be ignored.
I don't speak much fuel injection yet. The electronic stuff doesn't have a
pop pressure. Where in a high pressure mechanical system a hard line is charged
at high pressure and each injector is opened when its pressure gets high enough
to lift its pintle off its seat. The injector sprays until the line pressure
drops below pop pressure and the injector closes. The pressures involved tend to
fog the fuel with the expended pressure.
The Lucas system for race cars operates at 100 PSI. For diesel engine you
might see several thousand PSI.
The more energy it takes to open the injector the finer the
droplets or just a gas like fog.
The electronic systems just open the injector with about 50 PSI in the
line, and spray fuel with little energy being imparted into the fuel, so
atomization is minimal. I am guessing that anything that enhances atomization
would be helpful.
