The PDI system is a combination of the intake port fuel injection (PFI) method and the direct fuel injection (GDI) method in one internal combustion engine.
The PFI method reduces noise and PN (Particulate Number) and has high combustion efficiency in low output areas, while the GDI method has high output and high fuel efficiency. Because the PDI applies or combines the two systems in a driving space, it can maximize the advantages of both systems. It can enhance the experience of the driver and passengers by improving not only the driving performance, but also noise issues of the vehicle.

A complete understanding of the two systems is necessary because the PDI system uses both systems together. With knowledge and experience in PFI and GDI ECU (Engine Control Unit)s and control unit components, Hyundai KEFICO is proud to be a trusted partner in PDI systems.
