POWERTRAIN SYSTEMS Delphi Diesel Fuel Injectors Delphi Diesel Fuel Injectors are a family of highly versatile mechanical products that can be adapted for use in a wide range of light duty, medium duty and heavy duty fuel systems for both direct injection and indirect injection diesel engines. They are precisionengineered for both mechanically- and electronically-controlled pump line nozzle systems. They can be configured in conventional bar-type designs for axial-feed or side-feed, or forged body designs for a variety of angled side-feed applications. The nozzle valve of Delphi Diesel Fuel Injectors is mechanically closed by a high stress-capable spring, and the opening pressure is accurately set by high precision shims. Their proven, cost effective technology and application flexibility provide manufacturers with excellent value. Low Spring Injector Features and Options: Delphi offers a variety of diesel fuel injectors • Valve spring positioned low in injector body for reduced to meet a wide range of applications. moving mass • Holder body types: bar stock or forged construction • Body diameters from 17 mm upward • Compact profiles • Direct injection (DI) engine and indirect injection (IDI) engine versions available • Range of inlet and backleak configurations • Start-of-injection sensor injectors • Enhanced injection pressure option: o Specifically developed to be compatible with electronic unit pump (EUP) systems operating at high injection pressures o May be installed within the cylinder head, connecting to the EUP with a purpose-made high pressure line/connecting tube o Injectors withstand operating pressures up to 2,000 bar Nozzle Options: • Multi-Hole Nozzles for Direct Injection Engines o Long Stem Nozzle options available include: Guide diameters from 4 mm to 6 mm Various spray cone angles with injection hole configurations specifically tailored to individual engine requirements Outline to ISO standards more commonly with 7 mm or 9 mm diameter shank Variety of seat profiles available to suit application requirements Sac-type nozzles available with mini-sac or conical sac Valve covered orifice (VCO) nozzles that contribute to low carbon emissions Nozzle holes tailored to the engine application with hole diameters from 0.12 mm and with options for hole form pre-conditioning and holes with conical form o Long Stem Nozzles are available in two types: Standard guide configuration Extended guide configuration, which is important when space is limited or extreme injection pressures are encountered www.delphi.com | © Delphi.
