In reply to a message from Kirbert sent Sun 22 May 2011:
you ask, see if I can tell it.
those multi-hole injectors use only one valve but use a
small disc with around 6 holes to make a lot of small
droplets of Atomized fuel, that can Vaporize easier.
I probably said this somewhere,large droplets of fuel are
not good(take to long to vapoerize),so the smaller you can
make them the better for effincey.
a thin DISC can break up fuel quicker than a long tubular
hole, same size, same pressure.
that is precisly why direct chamber injection is the only
way for modern engines to go, instead of 40psi, its 2200psi,
stop and think about the droplet sizing.
as a useless bit of trivia, modern diesels have 25,000-
OK 1st car in modern era to use a disc in MPI injector
nozzle, our one and only GM, 1957 Corvette FI, thru
and this will get kirby(probably most of the guys)thinkin.
Pratt-Whitney great 3350hp,B29 WW2, bomber engines used
Direct chamber FUEL INJECTION, with the fuel injected down
thru the center elctrode of the spark plug, to get it in
center of chamber,and COOL THE PLUG FOR detonation control.
my question; what ever happened to that technology, it is
said that it would give to much better fuel milage, so it
was put into archives somewhere, orders from OIL companies.

The original message included these comments:
Any idea how the valve works? There aren’t multiple pintles to plug
those multiple holes I presume.
Why only for ethanol blends? Wouldn’t the same idea help with
