Delphi’s new heavy duty diesel system clicks
   
  The F2 range, which is designed for operation at up to 3,000 bar, provides an affordable way for manufacturers to meet many global emissions regulations including Euro VI, US10 and Japan PNLTR.  
     
 
Brief

Production is expected to begin prior to the introduction of Euro VI in 2013.“We believe that Delphi’s F2 is the most advanced and the most flexible diesel fuel injection system available for heavy duty and premium medium duty applications” said David Friday, Delphi Heavy Duty Diesel general manager. “
 
     
 
It will help our customers meet the toughest emissions standards through 2020 while protecting their investments in existing engine designs.”

Delphi also has been confirmed as the fuel systems supplier for an all-new heavy duty engine. “Selection for an all-new engine is extremely competitive,” Friday said. “Delphi’s success demonstrates the many benefits of our distributed pump architecture, which will deliver a competitive advantage in the marketplace.”

Separately, Delphi also has booked its first contract for the new F2R common- rail system, which has a conventional architecture using a remote pump. In the system, the pump is oil-lubricated, allowing exceptional durability at fuel pressures up to 3,000 bar. Several remote pump and distributed pump systems customers have chosen to use Delphi’s F2 hardware with the company’s new ETC 3 Electronic Truck Controller and control software package.

Flexible architectures

Delphi’s F2 family combines the flexibility of common-rail fuel management with world-leading ultra high pressures that Delphi achieves with its Electronic Unit Injection (EUI) and Electronic Unit Pump (EUP) technologies. The range comprises three architectures: the F2P and F2E distributed pump systems that provide a very high level of flexibility in packaging, performance and cost; and the F2R remote pump system that provides ultra-high pressures with the simplicity of a conventional common-rail layout.

F2P is ideal for cam-in-block engines that traditionally would have used an EUP architecture. The rail is pressurised by two or more cam-driven pumps and the layout and dimensions can be retained from a previous EUP configuration, eliminating the need to radically alter existing engines. Production of high output versions can be accommodated by adding extra pumping units, making it cost-effective to offer a wide range of ratings. Because the pumps are cam-driven, there is no loss of an auxiliary drive position on the engine.

The second of the distributed pump architectures, called F2E, is ideal for cam-in-head engines that traditionally would have used an EUI architecture. These can retain their existing layout and dimensions, using two or more cam-driven combination pump/injector units to match fuel delivery to the engine rating. When fuel is required at the nozzle, the pumping element is isolated and fuel is directed from the rail to the injector nozzle
