Gasoline Direct Injection (GDi) Systems

Demand for gasoline direct injection (GDi) technology is increasing - several research firms project the global GDi market will grow in excess of 10 percent annually through 2026. And when paired with electrification technologies, growth is forecast well into the next decade. As a leading OE manufacturer, Delphi is perfectly positioned to help you take advantage of this exciting opportunity. In addition to the latest generation OE technology, our GDi service programme includes the OE parts, tools and know-how to service this fast-growing, high-performance technology.

Delphi OE technology innovations

Our leading-edge 350 bar pressure gasoline direct injection system raises the bar, taking injection pressure from 200 to 350 bar. By injecting smaller droplets into the combustion chamber faster, the latest generation system delivers fewer hydrocarbons and particulate emissions – up to 70 percent - and increased fuel savings. And if that’s not enough, we’re already working on a 500 bar solution.

GDi maintenance

With the launch of the Hartridge Excalibur GDi Master, Delphi is now expanding its GDi service program offering in North America to include GDi and multiport gas fuel injector testing equipment. The Excalibur GDi Master is capable of providing up to 250 bar, and powerful flow and injection per minute rates allow it to test coil and piezo injectors of both GDi & PFI technology types.
