Atomisation

[bill.shurvinton at nokia.com]

As a matter of interest have you ever tried remote injectors where, at
high RPM you squirt into the trumpet. Requires a little more finesse in
programming I would guess but should give great atomisation up at the
high end

 The TBIs inject as far away from the valve as possible, into the
low-pressure (15-19 inches of vacuum) intake tract.  There's plenty of
*time* for vaporization to occur, plus the sonic flow across the
butterfly goes a good job of breaking the fuel up to start with.  The
port injectors are like pissing into a urinal; the fancy spray patterns
the books show only exist for a small part of the injector's duty cycle
if you look at one with a strobe.
