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.

Benefits

  • Highly efficient and compact, with integrated transfer pump
  • Engine oil-lubricated pump provides long term durability at high pressure operation
  • Fast response injector with small quantity injection control for precise combustion control
  • Fully flexible injection capability
  • Close-coupled multiple injection capability
  • Bespoke injector body, including slim line designs for packaging flexibility
  • Wide range of nozzle options available
  • High pressure (up to 2,400 bar) capability provides the potential to minimize the need for exhaust aftertreatment
  • On board diagnostics and dynamic trimming capability
  • Target emissions:
    • Euro VI
    • Post-US 10
    • Post-Japan NLTR
    • Tier IV

Typical Applications

The Delphi F2R High Pressure Heavy Duty Diesel Common Rail System is designed for four to 16 liter diesel engine applications. It is suitable for on- and off-highway vehicles.

Specifications

Peak pressure
2,400 bar 
Engine cylinder capacity 1.0 L to 2.6 L
Injector diameter 21 mm minimum
Pump Two or three plunger variants
Drive voltage 50 V

Performance Advantages

The Delphi F2R High Pressure Heavy Duty Diesel Common Rail System is among the most advanced fuel systems in the world. It allows engine manufacturers to combine the benefits of high pressure and fully flexible injection for optimized combustion across the engine speed range. This reduces the need for expensive aftertreatment systems and maximizes engine efficiency. With oil lubrication, Delphi has redefined common rail capability in terms of reliability and durability at high pressures.
