Delphi E3 Diesel Electronic Unit Injector
The Delphi E3 Diesel Electronic Unit Injector (EUI) is one of the
world's most advanced production diesel unit injector for high
performance heavy duty applications. The Delphi E3 EUI is an
integrated fuel injection device that contains a high pressure
pump and an electronically actuated injector. It is driven by the
engine's overhead camshaft, with one EUI per cylinder. Delphi's
E3 EUI dual valve design offers high-speed, ultra high pressure
operation and many advanced features including a flexible
injection capability enabling pilot, post and split injections.
The Delphi E3 EUI is designed to help manufacturers meet the
world's most stringent emissions regulations. It is the flagship of
Delphi's extensive range of high quality EUI products, which are
designed to fit the same injector pocket. This allows
manufacturers the freedom to meet a variety of emissions
standards with the same cylinder head design.
