The Delphi Diesel Electronic Unit Pump (EUP) is a robust high pressure fuel delivery device that is a part of a high performance fuel injection system for heavy duty "cam in block" diesel engine applications. The EUP uses proven valve technology from Delphi's highly successful EUI product line. It can be used in conjunction with either Delphi's mechanical injector (single valve system) or the Delphi Smart Injector for Diesel Engines (dual valve system) and interconnecting high pressure fuel delivery pipe.

Benefits

• High pressure capability
• Robust design
  
• Proven reliability
  
• Suitable for upgrading engines with mechanical fuel systems
  
• Shot-to-shot fuel adjustment for combustion optimization
  
• On board diagnostics and dynamic trimming capability (Glitch control)
  
• High speed actuation for improved injection performance
  
• Valve based on Delphi's proven EUI technology Target emissions: Euro III, IV, V and VI; US 07, US 10 and beyond; Tier III/IV; Japan NLTR and post-Japan NLTR

Typical Applications

The Delphi Diesel Electronic Unit Pump is suitable for nine to 16 liter heavy duty diesel engines for on- and off-highway applications. It can also be used in premium medium duty diesel engine programs.

Performance Advantages

The Delphi Diesel Electronic Unit Pump is part of a high performance fuel injection system which, in conjunction with either a Delphi Smart Injector or Delphi Mechanical Injector, provides a flexible and easy to package solution.  The EUP can be mounted in the engine block or in a cam-box as an upgrade for existing in-line pump engines.

The Delphi Diesel Electronic Unit Pump features the same performance advantages as the Delphi Electronic Unit Injector product line, including ultra high pressure injection and proven reliability.
