/ 8 1988 Hans Pete r Lenz, Rudolf Pisch inge r, Ernst Fiala , Diet rich Gwinner, Karl Puche r, Irolt Kill mann Legislation and the Catalyst: Practical Experience and Alternative Concepts Will the catalyst live up to its promises? Will there be a future for lean burn engines? What is our neighbors’ experience? (referring to Switzerland) – These were the questions on the agenda of the launch event of the AVL “Engine & Environment” conference series back in 1988. The first conference was held on August 1st and 2nd 1988 in the framework of the “Summer Academy Graz” and was opened by AVL founder Prof. Dr. Dr. h. c. Hans List. The priority topic of this launch event was the catalyst that had become mandatory in Austria in the year of the conference. Highlevel representatives from politics, industry and science attended the first “Engine & Environment” conference, including Prof. Dr. Hans Peter Lenz (Vienna University of Technology), Prof. Dr. Rudolf Pischinger (Graz University of Technology), Prof. Dr. Dr. Ernst Fiala (Volkswagen AG) and Prof. Dietrich Gwinner (Daimler Benz AG).* The first “Engine & Environment” conference was held in the framework of the “Summer Academy Graz”. Fuel Consumption and Emissions The scope of contributions ranged from “Emission laws in Austria and the catalyst as a technical solution” (Prof. Dr. Hans Peter Lenz), Prof. Dietrich Gwinner’s presentation on “The lean burn engine – a concept for the future” to Prof. Dr. Dr. Fiala’s contribution entitled “Will the decision on future transport systems depend on energy consumption and emissions?”. Dr. Fiala: “The way we operate vehicles today needs to be criticized; for example that the engine runs all the time, regardless of whether engine output is needed or not. The first thing that needs to be changed is that the engine should run only when actual output is required. The engine should stop when the car stands still (at traffic lights) and in coast mode. And when the engine runs it must not be operated at any operating point with poor efficiency, but possibly always close to the point of best efficiency. It is possible to adjust that.” What was a vision back in 1988 has virtually become established practice today. The future-oriented concept of an electric hybrid powertrain (see chart) completed professor Fiala’s visionary lecture at the first “Engine & Environment” conference in 1988. * Companies and job titles of the speakers refer to their positions at the time the conferences took place.
