With the Direct Acting Common Rail System, Delphi is bringing in production an innovative concept in Diesel Fuel Injection technology. In the Delphi Direct Acting Diesel Common Rail System, the injector needle is set in motion directly by a piezo ceramic actuator, rather than being moved via an electro-hydraulic circuit as with existing fuel injection technologies. This enables the injector to spray fuel into the combustion chamber faster and with much improved spray momentum and accuracy compared with current diesel fuel injection technologies. Another important feature is the fast needle opening and closing movement independent of the injection pressure. The result is a considerable reduction in emissions, more torque and power for better driveability and improved fuel economy. In this paper the authors provide a technical description of the unique injection performance characteristics of this novel approach and it is describe how the Direct Acting Common Rail allows unbeatable flexibility in the fuel injection strategy. Examples of the advantages and trade-offs are provided.
