Hyundai Ioniq (AE): Injector / Description and operation
Hyundai Ioniq (AE) 2017-2022 Service & Repair 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.
Specification Item Specification Coil Resistance (Ω)1.425 - 1.575 [20°C (68°F)]
