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 program includes the OE parts, tools and know-how to service this fast-growing, high-performance technology.

Raising the bar with OE technology

Our industry-first Multec® 14 (M14) 350-bar pressure 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. 

OE expertise in the aftermarket

We bring our OE expertise to the aftermarket too. Our GDi service programme features our award winning Multec® GDi multi-hole fuel injectors for optimised fuel delivery and combustion, low noise GDi high pressure fuel pumps and service kits, giving you access to OE parts for a high-quality, competitive service. Understand more about the common service issues with GDi.

More than parts

We also offer a comprehensive electronic and hydraulic diagnostic solution including our proven on-board DS diagnostic tool, a high-pressure diagnostic kit, HD3000, allowing technicians to safely set and electronically control any pressure test point up to 3000 bar and a wide-ranging low-pressure tester, LP35.
