Delphi Smart Injector
The Delphi Smart Injector for medium and heavy duty diesel
engines is a high pressure, electronically controlled diesel fuel
injector that is designed to be combined with Delphi's Electronic
Unit Pump (EUP) to provide a complete high pressure fuel
delivery system for "cam in block" engines or engines with
separate cam boxes. The injector's nozzle control valve is
electronically controlled to help reduce fuel consumption and
improve performance. The Delphi Smart Injector is designed to
help manufacturers meet the most stringent emissions
regulations.
