Back to the future again. The Injection Carb is re-invented. Check Bendix
service literature from the 1040s and 1950s on how it works. I always
thought that Rochester TBI was just an electronic update of Injection
Carbs.

One advantage of ICs is that you can pull negative Gs without flooding the
engine. Just the thing when you want to follow a Me109 into a power-dive.

Seriously, injection-carburators solved some real problems with high perf
piston engines in aircraft and duplicated most FI advantages at a fraction
of the cost.
