Hyundai Tucson: Engine Control System / Injector Description and Operation

Hyundai Tucson (LM) 2010-2015 Service Manual / Engine Control / Fuel System / Engine Control System / Injector Description and Operation

Description

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.
