The Delphi E3 Diesel Electronic Unit Injector (EUI) is one of the world's most advanced production diesel unit injectors for high performance heavy duty applications. The Delphi E3 EUI integrates a high pressure pump and separately controlled nozzle needle into a single fuel injection device. It is driven by the engine's overhead camshaft, with one EUI per cylinder. Delphi's E3 EUI dual valve design offers enhanced fuel delivery control at high-speed, ultra high pressure operation and many advanced features including a flexible injection capability enabling pilot, post and split injections to reduce engine noise and exhaust emissions.
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.
The Delphi E3 Diesel Electronic Unit Injector is suitable for nine to 16 liter heavy duty diesel engines used for on- and off-highway applications, including trucks, buses, generators, marine, and construction and agricultural equipment.
|Plunger diameter range||9 mm to 11 mm|
|Stroke range||Up to 19 mm|
|Engine cylinder capacity||1.5 L to 2.6 L|
|Peak pressure||2,500 bar|
|Drive voltage||50 V (operates on 12 V and 24 V vehicles)|
The Delphi E3 Diesel Electronic Unit Injector provides a major advantage for diesel engine manufacturers in meeting extremely stringent future emissions requirements. And with optimized hydraulic performance and one million miles durability, it represents a significant advancement in heavy duty diesel fuel injection technology.
The Delphi E3 EUI helps achieve extremely low smoke/particulate levels at any engine load and speed and, thus, helps reduce the need for large and costly aftertreatment devices.
