POWERTRAIN SYSTEMS Delphi Diesel Unit Pump Common Rail Systems Delphi Diesel Unit Pump Diesel Common Rail (UPCR) Systems are an innovative engine management concept that leverages advanced common rail technology — a proven "green" strategy — for small to medium diesel engine programs. The first generation system offers manufacturers a cost-effective, robust solution to help them achieve optimal fuel efficiency and meet stringent emissions standards, such as Euro 4. Delphi is developing a second generation system to help manufacturers meet emissions standards for Euro 5, Euro 6 and beyond. Key features of the Delphi Diesel UPCR System include fast solenoid diesel injectors and a common rail, a program-tailored engine control module (ECM), robust unit fuel pump with an inlet metering valve, as well as an efficient, low cost fuel filter. Low cost engine management system designed to provide the necessary high value essential to the market success of entrylevel market products and economy segment vehicle programs. Compact package size enables relative ease of application in very small engine programs. Light weight system contributing directly to CO2 reduction. High system pressure achieves high efficiency and excellent engine performance. (Up to 1,600 bar system pressure for the first generation system and 2,000 bar and above for the second generation.) Proven, compact fast response solenoid diesel fuel injectors are capable of up to five injections per cycle. The multi-injection capability enables precise tuning of combustion to help meet emissions, fuel economy and noise targets. Simple, robust unit pump provides reliable performance and contributes to an overall economical system cost. All-new engine control module options include a low cost, limited function ECM (DCM 2.5) and a full function module (DCM 3.x) to help meet the manufacturer's specific program targets. The UPCR System is able to drive devices such as a turbocharger (fixed or variable), an exhaust gas recirculation (EGR) valve and intake throttle control. Air management capability helps meet emissions standards, such as Euro 4, with the first generation system and up to Euro 6 and beyond with the second generation. Delphi Diesel Unit Pump Common Rail System Delphi's second generation Diesel Unit Pump Common Rail System is in development. Typical Applications The Delphi Diesel Unit Pump Common Rail Systems are specifically designed for 1- to 4-cylinder engine applications. They are ideal for small engine vehicles destined for emerging markets and for entry-level or mid-level vehicles that will be marketed in developed regions. They are also well-suited for other nonautomotive diesel engine products such as small agricultural and industrial equipment. www.delphi.com | © Delphi. All rig
