This is Delphi’s first diesel common rail application with DaimlerChrysler and the first time that DaimlerChrysler has entrusted a supplier with turnkey, complete systems responsibility, including components software and calibration.
The first phase of the project covers the applications engineering and supply of Delphi’s diesel common rail (DCR) 1600 system for passenger cars. Further phases are planned to extend the application to an additional vehicle.
The new system provides high injection pressure, improved nozzle design, superior hydraulic stability and enhanced software strategies. Delphi’s DCR 1600 delivers more complete combustion and provides more accurate control of very small volumes of fuel, introducing the option of up to five injection events. One of the many benefits is a reduction in NOx of up to 30% through the introduction of a late-pilot injection event.
