Delphi Focuses on Technologies Promising More Mobility and Less Consumption


Delphi Concept Car on Display; Press Conference Sept. 12 at 10:30 a.m.

FRANKFURT, GERMANY — At the 2007 International Automobil-Ausstellung (IAA) in Frankfurt, Delphi (PINKSHEETS: DPHIQ) is showcasing an array of remarkable innovations for new cars as well as vehicles that are about to enter the market. With a focus on CO2 reductions, below are a number of Delphi highlights ready to be discussed before, during and after the Sept. 13 - 23 event.

Delphi launching a new Gasoline Direct Injection (GDi) System

Delphi is launching a new, high-performance Gasoline Direct Injection (GDi) system that is optimized for the increasing use of turbochargers and bio-fuels as a flexible, cost-effective solution to global pressures on emissions and CO2 emissions. The heart of Delphi’s homogeneous GDi system -- named Multec 10® -- is a new multi-hole injector, designed for homogeneous lambda=1 combustion and available with spray preparation options optimized for a wide variety of combustion chamber shapes and static flow requirements. Delphi injectors’ high linear range make the system ideal for boosting applications, where significantly higher fuel rates on a full load are required without compromising fuel rate control at idle. Tests proved it is the quietest injector on the market. Delphi’s new GDi system is targeted to meet today’s most demanding emissions requirements -- including SULEV and EURO 6 -- without the cost of a complex after-treatment system.

Uprated Diesel Common Rail system for Euro 6 and US Tier 2 -- New 1,800 bar Common Rail System

A new version of Delphi’s proven diesel common rail system will allow compliance with Euro 6 and US Tier 2 Bin 5 without costly next-generation injection technologies. Delphi was the first to develop a solenoid injector that challenges the performance of servo piezo injection systems and the first to introduce closed loop control for diesel. It’s been a very successful strategy that has helped Delphi to grow steadily to become the world’s second largest supplier of diesel common rail systems. The new 1,800 bar system is expected to enter production for high performance Euro 5 applications during 2008. The system will also include a number of additional upgrades, largely to further improve hydraulic efficiency and spray optimization: High performance engines need excellent atomization and shaping of the injector spray, which means more injector holes -- either six of seven smaller holes in our Euro 5 system, compared with five or six in the Euro 4 system.

New Battery Monitor Supports More Electronics, Can Help Reduce Fuel Consumption

Delphi’s new Battery Monitor helps ensure optimal battery performance, making more electronics possible while ensuring sufficient power for starting the engine and, when integrated into a vehicle as part of active battery management, can help improve fuel efficiency and extend battery life.

Delphi’s Battery Monitor precisely measures current (I), voltage (V) and temperature (T), the three parameters essential to determining battery state of charge (SOC) and state of health (SOH). Using these parameters, Delphi’s Battery Monitor continuously updates SOC and SOH. Traditional methods of measuring current, voltage and temperature do not provide the high level of accuracy, range of measurement and resolution that Delphi’s Battery Monitor provides.

New Radar Generation: Multi Mode Sensor

A new generation of radar sensors used for smart or adaptive cruise control (with stop & go), autonomous brake assist, pedestrian classification and collision warning are being developed for a 2009 debut. Delphi’s newest radar sensors will enable better performance at a lower cost. The next generation of radar has a wide field of view and provides a single radar unit with long, medium and short-range capabilities, eliminating the need for multiple sensors. The beams are electronically scanned to provide enhanced performance, improved reliability and reduced cost compared to mechanically scanned radar. The multi-mode sensor is also smaller so it takes up less space and weighs less than conventional radar sensors.

Sensor Fusion: The Way to Multi-Functionality

Delphi’s unique approach provides a scalable architecture that allows for a customized feature set using common hardware for automakers. In addition, a single camera also simplifies vehicle packaging while providing multi-system functionality. It also reduces the number of standalone products that compete for limited windshield space. To further increase the effectiveness of its active safety systems, Delphi is fusing its vision and radar systems to generate greater intelligence and synergies for active safety systems.

Delphi’s Progressive Secondary Loop Technology for R-152a Application

Delphi believes the mild flammability of R-152a could be safely used with the application of secondary loop technology. That system keeps the R-152a entirely under the hood and away from the passenger compartment. Additionally, this secondary loop system requires less horsepower than today’s systems. In combination with Delphi’s system controller, it can provide a 13 to 19 percent reduction in fuel usage by the air conditioning system -- a valuable energy savings.

Delphi’s Halogen-Free Cable Debuts in 2007

New ultra-thin wall cable, touted for its halogen-free requirements, superior performance, durability, smaller size and recyclability, made its worldwide debut on the 2007 Toyota Tundra. It delivers superior performance and durability in a smaller and lighter package. Further, the material composite offers potential for the cable to be recycled at end-of-life.

An Environmentally Friendly Manufacturing Process for Steering Wheels

Delphi has instituted a new manufacturing process for steering wheels using non-ozone depleting polyurethane foam that aligns perfectly with energy-saving efforts. Tooling polyurethane to achieve a textured effect is a very critical manufacturing process. The polyurethane foam tool process used by Delphi for producing the steering wheels for a new car model launched this year is a unique three-dimensional computer modelling process that applies graining into the tool surface eliminating the need for master tools. The process allows Delphi to build the tooling 50 percent faster and reduce overall cost by 50 percent.

New Waferized Joint Connectors Impact Today’s Wiring Systems

Waferized joint connectors are a vital component of Delphi’s Electrical/Electronic (E/E) architecture system that enable miniaturization of a vehicle’s E/E architecture at a time when space is at a premium. These connectors dramatically impact the way that wiring systems will be assembled in the future by offering new possibilities for automating the production process.

Delphi Concept Car and Media Activities at the IAA (hall 5.1/ A04)

Delphi will present its advanced technologies and new innovative concepts at its booth (hall 5.1/ A04) at the 2007 IAA. To showcase some of the company’s technology advancements, Delphi equipped a concept car with its most-modern up-to-date E/E applications. Delphi’s Engineering Vehicle Electric/electronic (EVE) incorporates a Plexiglas “skin” giving a rare view of E/E architecture inside the car and clearly showing typically hidden electrical/ electronic devices, modules and systems. EVE also demonstrates manifold E/E-functions. The fully operable car is made of ideas -- a real car of imagination for car designers.

Delphi’s press conference is scheduled at the second press day -- Wednesday, Sept. 12 -- from 10:30 to 11 a.m. Individual interviews with Delphi executives can be scheduled upon request. On both press days, Delphi is offering media members to come on its booth for a “Vitamin-Start-up breakfast” at 9 a.m. and a “Vitamin Talk” at 5 p.m.
