Common Rail Systems
Delphi Ultra High Pressure Heavy Duty Diesel Common Rail System
The Delphi Ultra High Pressure Heavy Duty Diesel Common Rail System (UHPCRS) 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, ultra 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 the UHPCRS it has now developed a range of common rail systems with class-leading pressure capability and durability.
Benefits
Highly efficient, compact pump 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 valve stock for packaging flexibility
Wide range of nozzle options available
Ultra high pressure (up to 3,000 bar) capability provides the potential to minimize the need for aftertreatment
On board diagnostics and dynamic trimming capability
Target emissions:
Euro VI
Post-US 10
Post-Japan NLTR
Tier IV
Typical Applications
The Delphi Ultra High Pressure Heavy Duty Diesel Common Rail System is designed for four to 16 liter diesel engine programs. It is suitable for on- and off-highway applications.
Specifications
Peak pressure range 2,400 bar to 3,000 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 Ultra 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 ultra 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.
