It's quite simple. The fuel injector in screwed into the cylinder like a spark plug. Air comes through the intake valve, mixing with the fuel in the cylinder.
Conventional fuel enjection (port/sequential) has the fuel injector positioned above the intake valve, and fires when the valve is opened, in essence mixing the air/fuel mixture slightly above the valve.
The drawback I see is having another screw hole in an aluminum head. There are enough helicoils done now removing spark plugs every 5 years. Try removing a fuel injector after 15 years!
