Delphi’s Fuel Economy and Emission Solutions to be on Display at 2009 Vienna Motor Symposium

Delphi’s Direct Acting common rail injection system – now on Mercedes-Benz E-class sedan and coupe – showcased at event

Delphi presenting paper on breakthrough Direct Acting common rail system improvements in emissions, power and fuel economy

VIENNA, Austria -- Discussions at the 2009 Vienna Motor Symposium are sure to center upon how automakers and suppliers are striving to meet stringent emissions standards while improving fuel economy and performance. During the show, Delphi Corporation (Pinksheets: DPHIQ) will showcase a variety of solutions to those issues with a product line-up that includes a full range of gasoline and diesel engine management systems, modules and components as well as a line-up of fuel handling solutions.

In addition, Delphi is announcing that its revolutionary Direct Acting diesel fuel injection system is being used more widely by Mercedes-Benz vehicles, and Delphi executives will present a paper at the symposium providing a technical description of the premium system’s design, working principles and performance characteristics. The results presented in the paper show that the new Direct Acting common rail system is designed to meet the needs of future diesel powertrains that are being designed for high boost, high power density, and low emissions using advanced injections strategies and low fuel consumption -- potentially in conjunction with other technologies.

Delphi’s Display at Vienna Motor Symposium
The 30th International Vienna Motor Symposium takes place May 7-8, 2009, at the Congress Center in Hofburg, Vienna

Some of the Delphi Powertrain Systems products scheduled to be on display in Vienna include:

* Diesel Fuel Injection Systems
o Delphi Multec diesel common rail with balance valve fast servo solenoid injector
o Delphi Direct Acting common rail injection system with the Direct Acting Piezo injector
* Gasoline Engine System Technology
o Delphi Multec 20 Stratified Gasoline Direct Injection system with fast solenoid injector
o Variable Valve Actuation with two step valve lift control
* Transmission Management System
* Fuel Handling & Evaporative Management Systems

Mercedes-Benz E-Class Line-up Features Outstanding Fuel Economy, Reduced Emissions and Improved Engine Power and Torque
Delphi unveiled the next generation of diesel fuel injectors -- named the Delphi Direct Acting common rail system -- in Sept. 2008. Last December, Delphi announced that the new system would debut on the Mercedes C250 CDI.

Since the beginning of this year, Daimler has introduced two new models fitted with Delphi’s system: the new E-Class sedan unveiled at the North American International Auto Show in January and the new E-Class coupe which debuted at the Geneva Motor Show in March.

The new E-Class line-up takes advantage of Delphi’s revolutionary technology to offer drivers improved engine output and torque while reducing emissions and fuel consumption.

The new E-Class sedan is available with completely new four-cylinder engines in two versions equipped with Delphi’s Direct Acting common rail injection system:

* The E250 CDI with 150 kW/204 hp and 500 Newton meters develops a 25 percent higher torque than the previous V6 diesel engine but uses around 23 percent less fuel at only 5.3 liters per 100 kilometers (combined NEDC consumption). This corresponds to 139 grams of CO2 per kilometer.
* The E220 CDI BlueEFFICIENCY with 125 kW/170 hp also has a fuel consumption level of 5.3 liters per 100 kilometers.

The new E-Class coupe will be available with Mercedes-Benz’ new fuel efficient four-cylinder diesel engine: the E250 CDI BlueEFFICIENCY. The engine has an output of 150 kW/204 hp and develops a maximum torque of 500 Newton meters -- available at just 1600 rpm. This rates the engine as some 36 percent more powerful than the previous four-cylinder diesel engine while consuming around 17 percent less fuel: 5.1 liters per 100 kilometers (combined NEDC consumption, provisional figure). The corresponding carbon dioxide emission level is 135 grams per kilometer. Combined, these characteristics make the E250 CDI BlueEFFICIENCY one of the most economical vehicles in its class.

All the new E-Class engines meet EU5 emission standards.

Delphi Presenting Paper
On Friday (May 8), Delphi’s Dr. Detlev Schoeppe, Technical director for Delphi Diesel Systems, will present a paper detailing Delphi’s Direct Acting common rail injection system.

“In this paper, we are providing a technical description of the system design, working principle and the performance characteristics which are the basis for premium engine performance,” said Dr. Schoeppe. The design concept put into production has been made possible by the practical realization of a new and superior approach to the nozzle needle control. The previous servo needle control has been replaced by a unique design in which the piezo ceramic actuator now has direct authority over needle motion. Elimination of hydraulic servo also eliminates the need for back-lead drain and the associated parasitic losses.

The paper’s co-authors include:

1) Stefan Zuelch -- Chief Engineer, Advanced Diesel Engineering -- Delphi Diesel Systems in Gillingham, UK
2) Derk Geurts -- Chief Engineer, Diesel Common Rail System -- Delphi Diesel Systems in Bascharage, Luxembourg
3) Christian Gris -- Chief Engineer -- Delphi Diesel Systems in Blois, France
4) Dr. Rainer W. Jorach -- Chief Engineer, Common Rail Pumps -- Delphi Diesel Systems in Gillingham, UK

ABOUT THE SYMPOSIUM
