/ 11 1999 Franz-Josef Paefge n, Ebe rha rd Wag ner, Detlef Frank, Arun Jaura, Richa rd va n Bash uyse n, Tomohiko Kawanabe The contradiction between the demand for the highest efficiency and the lowest emission rates was the central topic of the 1999 conference. “What is the right decision to make between pollutant and greenhouse emissions? What alternative propulsion technologies have the greatest potential to challenge combustion engines, and will the market accept them?” These are just a few of the questions discussed at the conference. The keynote speech by Dr. Franz- Josef Paefgen (Chairman of the Board of Audi AG) was dedicated to the topic of “The internal combustion engine on the threshold of the next millennium – perspectives and challenges”. In his deliberations, Dr. Paefgen came to the following conclusion: “In the medium term there will be no alternative to the internal combustion engine. The sum total of its characteristics continues to make it the best propulsion system for our automobiles for the time being. To safeguard this, however, further and permanent optimization is required (...) And yet, efforts to develop alternative propulsion, such as the fuel cell, are indispensable, as the limited availability of fossil fuels will make alternative propulsion an absolute necessity. Consequently, my conclusion is not ‘either the one or the other’, but both: further development of the combustion engine and dedicated and intense pursuit of alternative propulsion.” The “Optimization potential of common-rail injection for lowemission and low-consumption diesel engines” was the topic of the presentation held by Dipl- Ing. Eberhard Wagner of Daimler Chrysler. His conclusion: “Additional measurement procedures and pre-calibration using state-ofthe art numerical and diagnostic methods will have to be used for future combustion processes (...). Without them, it will be impossible to meet the requirements of the future.” Ford Motor Company presented a “hybrid-electrical vehicle” with a 1 kWh NiMH battery, the Ford P2000 LSR. The first test results achieved with a prototype vehicle were presented by Dr. Arun Jaura: “As with all hybrid powertrains, the relative improvement in terms of fuel economy depends largely on the drive cycle. In the US City and Highway Driving Cycle, the LSR concept yields a reduction in fuel consumption by about 10 to 15 % compared to the nonhybridized vehicle with small CIDI engine. Compared to the serial production Taurus model, the fuel consumption will at least be halved through this systematic and integrated approach, where the vehicle has been viewed as an entire system.” Alternative drive concepts completed the range of topics of the 1999 “Engine & Environment” conference. Dipl.-Ing. Detlef Frank of BMW asked: “Hydrogen as a fuel for piston engines – a concept for the future?” and Dipl.-Ing. Matthias Bork of Opel presented “Perspectives of fuel cells for mobile applications“, listing the following criteria for future market success: “Vehicles running on a fuel cell system need to compete with combustion engines at all levels, but in particular in terms of safety, power, transportation capacity, convenience and costs. Market launch success will depend on these factors.” Zero Or Near Zero Emissions? – Pollutant Emissions versus CO2
