Gasoline Direct Injection (GDi)

Demand for gasoline direct injection (GDi) technology is continuing to grow and as one of the world's leading suppliers and developers of GDi fuel injection systems we are perfectly positioned to help our customers take advantage of this exciting opportunity.

Having been first to market with 350 bar GDi, we have now developed a high efficiency 500+ bar solution which is designed to minimize load on the engine valvetrain whilst delivering class leading performance.

GDi Injectors

Overview

Our range of high pressure fuel injectors provide best in class performance at 500+ bar pressure.

Continuity in design across our range allows a direct drop in replacement for customers looking to upgrade their operations from lower pressures.

Features / Benefits

Inwardly-opening injector with multiple laser drilled flow holes for flexible spray pattern and penetration control
500+ bar system operating pressure for improved spray and faster injection time
Benchmark level low noise performance
6 mm and 7.5 mm tip sizes

GDi Rails

Overview

Our GDi rails utilize the best design and manufacturing practices to store fuel at high pressure ready for injection. Our experienced engineering team is highly skilled in optimizing the design of the rail to ensure minimal fluctuations in pressure between individual injections, which is crucial in optimizing engine performance.

Features / Benefits

One piece forged stainless steel fuel rail
High crashworthiness due to single piece construction
Capable of infinite life fatigue resistance at 600 bar operating pressure
Design optimization for low noise, low stress and low cost
Available as a separate component or as an assembly with injectors pre-installed

GDi Pumps

Overview

Our range of high pressure fuel pumps provide best in class performance at pressures over 500 bar. Our unique plunger ring seal technology significantly improves pump efficiency, allowing our customers to upgrade their engines to 500+ bar pressure without increasing the load on the valvetrain. This helps avoid costly engine redesigns whilst continuity in design across the range allows them to be a direct drop in replacement for customers looking to upgrade their engines.

Features / Benefits

Up to 600 bar pressure continuous operation
Includes unique Plunger Ring Seal feature to improve efficiency and reduce stress on the valvetrain
Direct drop in replacement for existing GFP2 pump
Variable plunger diameters available to optimize performance and minimize cam loads; 6mm, 7mm, 8mm, 9mm
