Delphi To Present Future Of Automotive Technology at SAE 2002
World Congress
Release Date: February 25, 2002
DETROIT - Delphi (NYSE: DPH) engineers, researchers and scientists will reveal a
glimpse at the future of automotive technology March 4-7 at the Society of
Automotive Engineers (SAE) 2002 World Congress by presenting 37 technical
papers. Delphi experts will address the future of 42-volt, solid-oxide fuel cell and
brake-by-wire systems; ways to improve fuel economy and lower tailpipe emissions;
the development of new materials; and techniques for reducing noise, vibration and
harshness, as well as helping increase vehicle stability and safety in future vehicles.
"Delphi's more than 16,000 engineers, scientists and technicians continue to develop
the latest innovations that are driving tomorrow's technology," said J.T. Battenberg III,
Delphi chairman, CEO and president. "We are looking forward to participating in this
year's technical discussion during the SAE World Congress to share some of our
recent research findings that are sure to shape the vehicles of the future."
In addition to this year's technical presentations, Mark Sellnau, Delphi research
scientist, will be awarded the Arch T. Colwell Merit Award for his 2001 technical
paper "Cylinder-Pressure-Based Engine Control Using Pressure Ratio Management
and a Low-Cost Non-Intrusive Cylinder Pressure Sensor," which he co-authored with
General Motors' Frederic A. Matekunas, Paul A. Battiston, Chen-Fang Chang and
David R. Lancaster. This award, presented at the SAE Honors and Convocation on
Tuesday, March 5, recognizes the authors of papers of outstanding technical or
professional merit. Papers are judged primarily for their value as new contributions to
existing knowledge of mobility engineering. Sellnau's paper discusses a low-cost
engine control system that utilizes non-intrusive cylinder pressure sensors mounted
in the spark plug boss of four-valve-per-cylinder engines and presents the cylinder
pressure sensing concept, the sensor design and the system description. The
technology can be applied to gasoline or diesel engines to help improve fuel
economy and reduce emissions, and can significantly simplify the engine calibration
process.
Highlights of nine significant Delphi papers to be presented at this year's SAE World
Congress include:
"Fuel Economy Improvements in an SUV Equipped with an Integrated Starter
Generator"
(Monday, March 4, at 1:30 p.m., room D0-04AB, Cobo Center)
The recent surge in gas prices has drawn attention to the lower average fuel
economy of the growing class of sport utility vehicles (SUV). Vehicle manufacturers
are looking for ways to improve the fuel economy of these vehicles without affecting
performance or utility. One possible solution is the 42-volt integrated
starter-generator (ISG). The ISG offers the ability to reduce fuel consumption through
the use of engine-off during coast-down and idle, early torque converter lockup with
torque smoothing, regenerative braking and electrical launch assist. This paper
details the fuel economy benefits offered to SUVs with an engine stop-start function
implemented with an ISG. Dynamometer test results for an SUV equipped with a
Delphi-designed Energen-10™ ISG are presented.
"The BRAKE Project - Centralized Versus Distributed Redundancy for
Brake-By-Wire Systems"
(Monday, March 4, at 2:30 p.m., room O2-35/36, Cobo Center)
Today, many system vendors develop complete chassis systems. The
characteristics of each system are determined by both hardware and software. This
paper presents the objectives and preliminary results of the BRAKE project - a
collaborative effort of Delphi, Infineon Technologies, Volvo Car Corporation and
WindRiver. The objective of this project is to use microelectronics technologies to
design a distributed brake-by-wire system, including: a distributed fault-tolerant
system for enhanced safety, an extension of the OSEK-based operating system for
a distributed time-triggered architecture, and an open interface between vehicle
control and brake system control.
"Fast Start-Up On-Board Gasoline Reformer for Near Zero Emissions in
Spark-Ignition Engines"
(Monday, March 4, at 3:30 p.m., room W2-70, Cobo Center)
The Ultra-Low-Emission Vehicle (ULEV) II standards proposed for 2004 introduction
in California include a Super-ULEV (SULEV) standard. Gasoline-fueled vehicles that
robustly meet SULEV standards over their useful lives offer a significant step toward
eliminating the automobile as a source of regulated pollutants. Developing SULEVs
can significantly reduce an OEM's fleet average non-methane organic gas (NMOG)
emissions. This paper describes recent progress in Delphi's program to develop a
gasoline-fueled vehicle with an on-board reformer to provide near-zero tailpipe
emissions and shows results from an engine linked to an experimental, fast start-up
reformer. The authors present both performance data for the reformer as well as
engine emissions and performance results. Program results continue to show an
on-board reforming system to be an attractive option for providing near-zero tailpipe
emissions to meet low emission standards.
"Cold Starting Performance of a 42-Volt Integrated Starter Generator System"
(Tuesday, March 5, at 3:30 p.m., room D2-15, Cobo Center)
Over the next several years, vehicle manufacturers will begin to use a 42-volt-based
system to integrate the starter and generator into one unit known as an integrated
starter-generator (ISG). The ISG, its associated electronics and battery pack form a
system that has the ability to perform torque smoothing of the driveline, electrical
launch assist, regenerative braking, high power generation, engine stop/start and
other features. One of the important tasks to be performed by the ISG is starting the
internal combustion engine under extremely low temperature conditions. Cold
starting requirements have a great influence on the design of any ISG system. This
paper examines how the cold starting requirements affected the design of the Delphi
Energen-10™ ISG system. Test results performed at -29°C for the cranking of a
gasoline 4.0-liter, V-6 powertrain are presented. A discussion of the electric motor
control strategy used during the cold starting events with an ISG system is also
included.
"Solid-Oxide Fuel Cell Auxiliary Power Unit - A Development Update"
(Tuesday, March 5, at 10:30 a.m., room M2-29, Cobo Center)
Delphi and BMW were successful in demonstrating an Auxiliary Power Unit (APU)
based on solid-oxide fuel cell (SOFC) technology in February 2001. An SOFC APU
generates power using hydrogen and carbon monoxide reformed from fuels such as
gasoline, diesel, or natural gas. This paper describes Delphi's most recent activities
in the development of a second-generation APU. This development has been targeted
toward resolving the fundamental issues with the following key subsystems: fuel-cell
stack, fuel reformers, and energy and thermal management. Major focus has also
been directed at system integration challenges to make a more robust and efficient
product.

Exhibiting full scale prototype SOFC systems hold more credence to me than showing mock-ups (full scale non-working models, e.g. AUTOmony), or the sale of a few fuel cell test stations., or the sale of a miniuscle amount bus fuel cell systems. The stationary power market is over twice as large as the automotive markets, and fetch 20 times the value for an equal amount of products. |
