My thought is that air shrouded (or "boosted") injectors would do the
deed--and also improve atomization in the bargain--quite admirably.

The fuel injector could put the fuel into a small "pre-chamber" over a
fairly long pulse width, and then compressed air is quite capable of
putting it into the port in a highly atomized state quite suddenly.
