Common Rail Systems

Delphi F2R High Pressure Heavy Duty Diesel Common Rail System

The Delphi F2R High Pressure Heavy Duty Diesel Common Rail System (F2R System) is designed for medium and heavy duty diesel engine programs with high pressure requirements. Delphi offers a complete common rail system including electronic injectors, common rail, sensors, pipes, high pressure fuel pump, electronic controller and fuel filtration.

Delphi has earned a reputation for durable, high technology electronic unit injector and electronic unit pump systems. With this system it has now developed a range of common rail systems with class-leading pressure capability and durability.
