Kia Sportage: Engine Control System / Injector Description and operation
The GDI injector is similar to a standard injector, but sprays fuel at a much
higher pressure directly into the combustion chamber and has a swirl disc to
get the fuel swirling as it exits the nozzle. This aids in atomization of the
fuel.
The ECM controls both the feed circuits (high side) to feed voltage to the injectors
and the ground circuits (low side) to energize the injectors. Also, the feed
for 2 injectors comes from the same driver set. As the ignition coils are paired
with cylinders (1-4 and 2-3), the injectors are also set up in pairs.
