POWERTRAIN SYSTEMS Delphi Multec® Light Duty Diesel Common Rail System The Delphi Multec® Light Duty Diesel Common Rail System is a robust, modular fuel injection system. This highly popular system offers automotive manufacturers the best value light duty diesel fuel injection system in the industry. The system features balanced valve, extremely fast actuating servo-solenoid injectors, which deliver precise metering and performance similar to competitive servo-piezo technologies, but at lower cost. Delphi's DFP6 high pressure fuel pump, which may be included in the system, offers best-in-class volumetric efficiency, well above 90 percent at very high pump speed. The compact size of the DFP6 pump and injectors allows packaging flexibility with reduced weight. And, the system also includes Delphi's patented Individual Injection Characterization (I3C) control strategy, which helps provide optimal control of multiple injections over the life of the engine to help maintain low noise and reduced emissions. The key elements of the Delphi Multec Light Duty Diesel Common Rail System include: Delphi Multec Light Duty Diesel Common Rail System (4-Cylinder Engines) Compact, state-of-the-art fuel injectors for best possible packaging (17 mm, or 19 mm pencil diameter) High pressure modular pump range (0.3 to 1.2 cm3/rev). The DFP6 single plunger pump enables operation up to 2,000 bar, with the inherent capability of 2,200 bar DFP6 roller cam shoe mechanism optimized for reduced torque, dynamic mass and noise via the patented Delphi static shoe guide Proven, tubular-shaped common rail Reliable electronic control unit (ECU) with 32-bit processor Filter customized to application requirements to ensure performance over the life of the engine Delphi now offers a new family of Diesel fuel injection equipment that offers improved performance through increased injection pressure--up to 2,500 bar--leakage reduction, and increased multiple injection optimization because the injectors are capable of up to nine injections per cycle. These innovations translate into better injection control and better combustion, thus reducing fuel consumption, CO2 and other emissions. The new system is not yet in production. Contact Delphi for further information. Simple, modular, robust and precise diesel fuel injection system with a high level of injection performance Stable emissions and excellent acoustic performance throughout the life of the vehicle Low backflow injectors do not require backflow cooler mechanism Robust, durable and modular pump family designed for high pressure bar capability and can support a variety of packaging and drive requirements Tubular common rail is hydraulically optimized to dampen waves, enabling precise and multiple fuel injections Simple, reliable and cost effective electronic controller design works with 12 V battery voltage, thus boost voltage is not required The system's fuel filter is specifically designed to withstand the life expectancy objectives of the engine

Delphi Multec® Light Duty Diesel Common Rail System Typical Applications The Delphi Multec Light Duty Diesel Common Rail System is suitable for the entire range of light duty vehicle applications, including future generations of downsized engines in a variety of vehicle classes. For some passenger vehicles, the system can help meet Euro 6 Step 1 European emissions standards without the need for nitrogen oxide (NOx) aftertreatment. To meet an engine manufacturer's requirements, the system can also integrate diesel particulate filter strategies and NOx exhaust aftertreatment strategies. Performance...
