Do they wait for compression, then inject the fuel in a spray? Even better.

All diesels work that way. There is no other way to control
ignition timing. The high compression heats the air charge to a
temperature that will ignite the fuel as it is injected, so that
injection timing controls ignition timing, and the length of the
injection time, and therefore the volume of fuel injected, controls
the power produced. There is no throttle butterfly to control incoming
air. Full air charge is needed to generate the high pressure and
temperature.
