Gasoline Direct Injection (GDI) has been integrated into quite a few
automotive engines over the past few years. After reading an article
about it, and googling for the availability of GDI fuel injectors I
started thinking this might be a cool direction to go in for those
persons interested in engine design, particularly the HCI Radial
guys.

Forget GDI on an aircraft engine, it is a good thing only when you use
the engine a very low charge with EGR (exhaust gas recirculation) system.
The GDI engines are not better than standard engines at full charge.
For an airplane we kneed light engines and best fuel use at full power.
It may be achieve with mechanical injection.
The best I know is the IO320 in the homebuilt power range, it is
better than most of automotive conversion.
